Convincing By Stories

When someone writes a story, something is being invented. It is not merely a narration of facts, since otherwise it would not be a story at all, but a history, or some other kind of account regarding the world as it is.

Nonetheless, there is always something in common with the real world, or something implicitly supposed to be in common with the real world. Thus for example The Betrothed presupposes and sometimes mentions actual facts about seventeenth century Italy, even while including an invented narrative about individual persons. Similarly, the film Interstellar  presupposes and sometimes mentions various scientific facts about the universe, even while adding various other things which almost certainly cannot exist in the real world, like time travel.

It is not difficult to see that it is essential to stories to have such a background in common with the real world, for if there were absolutely nothing in common with the real world, the story would be unintelligible. Among other things, a story must follow the laws of logic, at least most of the time, or it will be impossible to understand it as presenting an intelligible narrative. Consequently, a story will make sense to us insofar the background, real or supposedly real, makes the invented narrative a plausible and interesting one. Thus Manzoni’s novel must present a narrative that seems like a possible one in the context of seventeenth century Italy. Likewise, if the background implies that the invented narrative is highly implausible, the story will not make much sense to us. Thus, for example, while I enjoyed most of Interstellar, my experience was somewhat spoiled by the addition of time travel, and this generally tends to be the case for me when stories involve this particular idea. This is largely because time travel is probably logically impossible. To the degree that other people do not think that it is, or do not feel as if it were, it is less likely to disrupt their enjoyment of time travel stories.

The result of all this is that stories are one of the most effective ways to convince people of things. When we are giving our attention to a story, we are not in the mood for logical analysis or careful thought about the precise nature of the real world. And yet, in order to understand the story, we need to implicitly distinguish between the “real background” and the “invented narrative.” But in fact we may not be able to draw the line precisely; if someone does not know the details of the history of seventeenth century Italy, he will not actually know the difference between the things that Manzoni takes from the real world, and the things that Manzoni invents.The result is that a person can read the book, and walk away believing historical claims about Italy in the real world. These claims may be true, but they might also be false. And this can happen without the person having any explicit idea of learning history from a novel, and without noticing that he has become convinced of something which he previously did not believe.

 

Let’s Draw a Line

James Larson, in the note currently at the beginning of his website, accuses Pope Francis of heresy:

Note (April 16, 2016): In order to add clarity as to the nature of the explicit heresy taught in Amoris Laetitia, I have added one paragraph approximately 2/3 of the way through the article below. It reads:

Herein resides the essence of this heresy. It lies specifically in teaching that there is a “gradualness” applicable to the possession of charity and sanctifying grace. It is Catholic dogma that possession of supernatural charity is an ontological state created by sanctifying grace added to the soul, that one cannot possess this charity unless living in this substantial state, and that it is this state of being which is absolutely necessary for receiving the Eucharist and other sacraments. It cannot be possessed by a person living in objective mortal sin, or by any person who is in some process of pastoral effort working towards the attainment of some “ideal”.

Larson is saying that sanctifying grace is a binary state, that it cannot be possessed by someone “living in objective mortal sin,” that these items are Catholic dogmas, and that Pope Francis contradicts them. The text in which he supposedly does this is paragraph 305 of Amoris Laetitia:

Because of forms of conditioning and mitigating factors, it is possible that in an objective situation of sin – which may not be subjectively culpable, or fully such – a person can be living in God’s grace, can love and can also grow in the life of grace and charity, while receiving the Church’s help to this end.

Larson is mistaken on almost every point. It is true that sanctifying grace would normally be considered a binary condition, where either you have it or you do not. But the Catholic Church does not typically create doctrines concerning deep matters of ontology. If someone were to assert that some people are in a vague condition where it is unclear whether or not they are in a state of grace, just as it is unclear whether some people are actually bald or just almost bald, this would not be a heresy. Nowhere does the Church condemn such a view.

But this is beside the point. It is entirely obvious that Pope Francis makes no such assertion in the text under consideration. Nor does he assert this, or anything like it, anywhere else in Amoris Laetitia.

“Living in objective mortal sin” refers to the “objective situation of sin” in the text of Pope Francis, and refers to the general idea of living a life where one regularly performs acts which the Church considers to be objectively grave sins. Larson asserts that the Church teaches that such a person cannot be in a state of grace.

This too is mistaken. The Catechism of the Catholic Church states:

1857 For a sin to be mortal, three conditions must together be met: “Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent.”

1858 Grave matter is specified by the Ten Commandments, corresponding to the answer of Jesus to the rich young man: “Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and your mother.” The gravity of sins is more or less great: murder is graver than theft. One must also take into account who is wronged: violence against parents is in itself graver than violence against a stranger.

1859 Mortal sin requires full knowledge and complete consent. It presupposes knowledge of the sinful character of the act, of its opposition to God’s law. It also implies a consent sufficiently deliberate to be a personal choice. Feigned ignorance and hardness of heart do not diminish, but rather increase, the voluntary character of a sin.

1860 Unintentional ignorance can diminish or even remove the imputability of a grave offense. But no one is deemed to be ignorant of the principles of the moral law, which are written in the conscience of every man. The promptings of feelings and passions can also diminish the voluntary and free character of the offense, as can external pressures or pathological disorders. Sin committed through malice, by deliberate choice of evil, is the gravest.

The Catechism is clear that doing something objectively wrong is not enough for a sin to be mortal, or to exclude someone from the state of grace. In order for this to happen, there also needs to be “full knowledge” and “complete consent.”

The text does not explicitly address the kind of “objective situation of sin” that Pope Francis and James Larson discuss. Much less, therefore, does it assert that a person in such a situation cannot be in a state of grace. However, it is not difficult to see from the above text that a person could be in such a situation without mortal sin. One of the factors that can “diminish the voluntary and free character of the offense” is “external pressures.” The situations under discussion are precisely situations where there are external pressures. That is why they are considered “situations” as opposed to an arbitrarily repeated series of actions. Since the consent must be “complete” and since it can be diminished by these pressures, a person might very well fail to sin mortally in such a situation, even if the situation lasts for a long time.

We can see that Larson’s positions do not correspond very well with anything that the Church actually teaches. Why then does he make these assertions?

I suggest that we have here a case of highly motivated thinking. Larson wants to believe that sanctifying grace is a binary condition, he wants to believe that a divorced and remarried person could not be in that condition, he wants to believe that these are teachings of the Church, and he wants to believe that Pope Francis contradicts these things.

Why would someone have such desires? Larson says in article 25:

Since Pope Francis’ recent interviews and his letter to the editor of La Civilta Cattolica, I have received emails from traditional Catholics which speak of a new level of despair. It is as though they are desperately seeking some explanation of what is happening with the Papacy and the Church which will allow them to escape from coming to some dreadful conclusion.

The situation reminds me of a passage from Robert Bolt’s A Man For All Seasons. In the face of all the forces of evil moving in to ensnare and destroy him, Sir Thomas More offers the following impassioned words to his beloved daughter:

“Listen, Meg, God made the angels to show Him splendor, as He made animals for innocence and plants for their simplicity. But Man He made to serve Him wittily, in the tangle of his mind. If He suffers us to come to such a case that there is no escaping, then we may stand to our tackle as best we can, and, yes, Meg, then we can clamor like champions, if we have the spittle for it. But it’s God’s part, not our own, to bring ourselves to such a pass. Our natural business lies in escaping. If I can take the oath, I will.”

It seems evident that the “tangle of the mind” from which traditional Catholics are now desperately trying to escape is the apparent overwhelming evidence that their Church is being destroyed from within. They dread that they are being irresistibly backed into a corner where they will be forced to conclude that the Church, in what they always considered to be her inviolable nature (if she is to be considered real at all) has contradicted this nature, and has therefore been proved to be a human invention, and not the work of God. In other words, they fear the loss of their faith.

I think this is a correct description of how many people feel. I think it is also a correct description of the way Larson himself feels, and I think it can explain why he desires to hold the above opinions concerning Pope Francis and Amoris Laetitia. This might seem a bit paradoxical. He accuses Pope Francis of heresy. Would not this be a very good example of the kind of thing he should be hoping to avoid?

Yes, in one way, but in another way it is an advantage to him if Pope Francis explicitly falls into heresy. This is important to him. In the first quoted passage, he mentions the “nature of the explicit heresy” taught by Pope Francis. It is not only heresy, but “explicit heresy.”

When people change their minds, they often do so gradually, and by degrees, and in such a way that sometimes they do not even notice that they have changed their minds. It follows that if someone does not want to change their mind, they have a reason to be cautious about gradual changes of opinion. Such changes not only could lead to what they do not want, namely changing their mind, but they could lead to this without the person even noticing it has happened.

Another point should be made about this. I pointed out here that despite the fact that it would be unreasonable to say that getting one year older makes you pass from “not being old” to “being old”, this does not prevent you from growing up. In the same way, if someone changes his mind gradually, at each point he may be able to say, “this change is too small to constitute a passage from not having changed my mind to having changed my mind.” He may be quite right. But this will not prevent it from being true at the end that he has changed his mind in comparison with his original position.

And just as individual human beings change their minds, so the Church changes its mind, gradually and by degrees, and sometimes without saying that a change has occurred. So just as someone who wishes to avoid changing his mind should be cautious about gradual changes, so someone who does not want the Church to change its mind will wish it to be cautious about gradual changes. This is what is happening here with Larson’s argument. It is an advantage to him if Amoris Laetita is explicitly heretical, because in that case it can be completely rejected, preventing the process of gradual change. If the document is not heretical (and it is not) it will be bound to cause gradual changes of various kinds, and there is no way to predict the end results in advance.

In a certain way, traditionalist Catholics are often more reasonable in this regard than others who would be considered “conservative” rather than traditionalist. Thus for example Jimmy Akin says:

11. Does the document foresee any possibility for sacramentally absolving and giving Communion to people who are civilly remarried if they are not living as brother and sister?

It does. In the main text of the document, it begins by noting certain principles to be taken into account, stating:

For an adequate understanding of the possibility and need of special discernment in certain “irregular” situations, one thing must always be taken into account, lest anyone think that the demands of the gospel are in any way being compromised.

The Church possesses a solid body of reflection concerning mitigating factors and situations.

Hence it can no longer simply be said that all those in any “irregular” situation are living in a state of mortal sin and are deprived of sanctifying grace.

More is involved here than mere ignorance of the rule. A subject may know full well the rule, yet have great difficulty in understanding “its inherent values,” or be in a concrete situation which does not allow him or her to act differently and decide otherwise without further sin. . . .

The Catechism of the Catholic Church clearly mentions these factors: “imputability and responsibility for an action can be diminished or even nullified by ignorance, inadvertence, duress, fear, habit, inordinate attachments, and other psychological or social factors” (CCC 1735).

In another paragraph, the Catechism refers once again to circumstances which mitigate moral responsibility, and mentions at length “affective immaturity, force of acquired habit, conditions of anxiety or other psychological or social factors that lessen or even extenuate moral culpability” (CCC 2352).

For this reason, a negative judgment about an objective situation does not imply a judgment about the imputability or culpability of the person involved. (AL 301-302).

The document thus envisions the case of a person who may be living in an objectively sinful situation but who is not mortally culpable because of a variety of factors of a cognitive or psychological nature.

Nothing in this is new. The Church has long recognized that people living in objectively grave sin may not be in a state of mortal sin.

Akin is right that “the Church has long recognized that people living in objectively grave sin may not be in a state of mortal sin.” This was discussed above. But “nothing in this is new” is simply not true, if it is understood in relation to the question about communion for the divorced and remarried. The Pontifical Council for Legislative Texts stated in 2000:

Any interpretation of can. 915 that would set itself against the canon’s substantial content, as declared uninterruptedly by the Magisterium and by the discipline of the Church throughout the centuries, is clearly misleading. One cannot confuse respect for the wording of the law (cfr. can. 17) with the improper use of the very same wording as an instrument for relativizing the precepts or emptying them of their substance.

The phrase “and others who obstinately persist in manifest grave sin” is clear and must be understood in a manner that does not distort its sense so as to render the norm inapplicable. The three required conditions are:

a) grave sin, understood objectively, being that the minister of Communion would not be able to judge from subjective imputability;

b) obstinate persistence, which means the existence of an objective situation of sin that endures in time and which the will of the individual member of the faithful does not bring to an end, no other requirements (attitude of defiance, prior warning, etc.) being necessary to establish the fundamental gravity of the situation in the Church.

c) the manifest character of the situation of grave habitual sin.

The text is clear: people in the situation under discussion are not to be given communion, whether or not they are in the state of grace. It is true that they do not assert that such people are necessarily in a state of sin, as James Larson does, but the prohibition does not depend on their subjective condition. And thus when asked whether he intended to change anything, Pope Francis said that he did intend such a change:

Rocca: Thank you Holy Father. I see that the questions on immigration I had thought of have already been asked, and you have responded very well. So, if you will permit me to ask a question on another event of the last few days, which was your Apostolic Exhortation.

As you know well, there was much discussion on one of many points – I know we have concentrated a lot on it – but there has been much discussion after the publication…Some maintain that nothing has changed with respect to the discipline that governs the access to the Sacraments for the divorced and remarried, and that the law and the pastoral practice and obviously the doctrine remains the same; others maintain instead that much has changed and that there are many new openings and possibilities.

And the question for a person, a Catholic, that wants to know: Are there new concrete possibilities that did not exist before the publication of the Exhortation or not?

Pope Francis: I can say yes. Period. But that would be too small an answer.

Akin’s way of thinking goes, “This does not contradict the Church’s current teaching. So it’s nothing new.” Larson, far more reasonably, recognizes in practice (although probably not in principle) that “this does not contradict the Church’s current teaching” can be true at every point in time, without this preventing the Church from changing its teaching in the end. By asserting that Amoris Laetitia is heretical, he hopes to draw a line, in order to remove the possibility of gradual change ultimately resulting in substantial change.

James Chastek, talking about disagreement on philosophical topics, says:

We care too much about philosophical topics ever to agree about them, and we achieve widespread successful consensus on scientific matters because we care very little which theory turns out to be true. The beauty and utility of math and science are there for anyone to see, but it’s not as if any one would kill, die, be celibate, or riot over them. Math and science of themselves, cut off from any reference to the mytho-philosophical (like the praise or the defiance of the gods) are not the sort of thing that one would think to praise in epic poetry, polyphonic splendor à la a Gounod Mass, or even a pop song.

We have discussed much the same issue here, although we pointed out that caring too much is only one part of the cause of such disagreement. Something else can be seen in the case of Larson’s disagreement with Amoris Laetita. It is not merely that he cares about the position he holds. He cares about agreement and disagreement, directly. For the reasons stated, he wants to disagree with Pope Francis. Thus in order to be sure that he does, he needs to describe the Pope’s position in various ways.

This is not uncommon. People frequently care not only about their positions, but also about the fact that they agree with certain people, and that they disagree with others. People often draw lines exactly for this reason, namely in order to disagree with someone else.

 

Easter for Unbelievers

In the atheist blogosphere today, one finds a somewhat embarrassed acknowledgement of the feast of Easter. Thus for example Brian Leiter says, “Happy Easter… from the Antichrist,” namely himself, and John Loftus says, “Since I don’t think anything significant happened on Easter I’m not treating it as a special day.”

There are a number of problems with this attitude.

First, it is self-refuting. If Loftus thinks that Easter shouldn’t be treated as a special day, then he should not treat it as a special day, which means that he should not go out of his way to mention it.

Second, as I pointed out in an earlier post, whether you should treat the traditions of your ancestors with respect is a different question from the question of whether the beliefs of your ancestors were true. Loftus assumes that if you think the response to the latter question is negative, you should also think that response to the former question is negative. But this is an unjustified assumption, and is unlikely to be true. It is however typical of Loftus, who frequently attempts to justify his practice of ridiculing believers.

Third, there is a more basic point concerning the celebration of feasts and holidays in general. The meaning of the feast is never wholly exhausted by the historical particulars on which it is based. Francis Hunt says about the case of Easter,

In my own personal journey – for I was born and raised a Catholic – it was the realization that I did not, in fact, believe in the resurrection of Jesus from the dead which led me to stop referring to myself as a Christian, even before I was willing to admit to myself that I did not believe in God either. I still have great admiration for the figure of Jesus, for much of the message he preached, for his integrity, his courage, his gentleness, his insights into life and human nature, his radical message of how we could find a way to live as individuals and communally by following better, more noble ideals than those of competition with and dominance over each other. But none of this makes me a Christian, for I do not believe (have faith) that he was the son of God who died, was buried and on the third day rose from the dead.

All of this said, I do not believe that Easter is irrelevant, or that we should not celebrate it. One of the strengths of Christianity (as of all great religions) is its ability to take the most central human experiences and weave them into a narrative which gives us eternally sense-seeking humans some kinds of answers to the questions and mysteries which we constantly experience in living our lives. From our first emergence into (self-)consciousness hundreds of thousands of years ago up to the last handful or two of decades, our human experience has been existentially and immanently connected with the basic course of nature, the year, the seasons. Winter is that season where our survival, our very existence is acutely threatened – it is that time where it is often extremely difficult to find enough nourishment and shelter from the elements to just continue living. If spring does not come soon we will die. And when the days finally become longer and warmer, when nature finally produces enough new life to ensure that we will not starve, that is surely a reason for celebrating. Moreover, having survived a time where much of the world seemed cold and bare and lifeless, it is natural that our thoughts should turn to the cycle of dying and the birth of new life out of that death.

Although Christians like to think that their story is original, nearly all the memes which are gathered together in the Easter narrative are general human ones which can be found in many religions and philosophies; death and the triumph of life over death, the strength of weakness, the suffering of the righteous and their vindication, the belief that justice is ultimately stronger than human power constellations, the sacrifice of the gentle king for the good of the land and the people, even the incarnate god. What makes Christianity unique is its insistence on the essential historicity of its teaching and its consequent claim to universal validity and truth.

As a non-believer I can still be touched and moved by the powerful drama and deep insights into life and the human condition contained in the Easter story. I can find inspiration in a message which proclaims hope beyond hopelessness, vindication beyond failure, new joy beyond despair. Where I cannot journey with the Christians is their assertion that their narrative is a basically factual statement of a particular, explicit, essential intervention of an all-powerful, all-loving God into history with reality-transforming ontological consequences on a cosmic – and even para-cosmic eternal (beyond all space and time) – level. And, of course, it is precisely this assertion which is the heart of the message for Christians.

I am aware that many believers may see my position as impoverished. If their belief should be true, then they are right. I can remember my own years as a believer (or, more accurately, as one who wanted to believe), I can remember the impression of desolation and emptiness I had when the sacrament was moved to a side-altar, the empty tabernacle door left heart-achingly open, the cross on the altar draped in a purple shroud. I remember the feeling of joy and lightness spreading through a darkened church during the Easter Vigil on Holy Saturday night as the Easter fire is kindled, the Easter candle lit from it and then the light springing from candle to candle in the church, accompanied by the thrice-repeated responsory, Lumen Christi – Deo Gratias. Much of this is, of course, wonderfully staged theatre, (holy) smoke and mirrors, but the feelings induced are none the less real for all that. There is a deep part of us which has a need for, and responds to ritual and solemnity and the only demand I would place on such ritual is that it should be honestly and well done.

Hunt is not using very precise language here, but his basic point is that Easter is not exhausted by the particular claim that Jesus rose from the dead, but the feast is also meant to express certain universal truths. And this would be a sufficient reason for a person to celebrate the feast of Easter, even if they do not believe the particular historical claim about Jesus.

The basic issue is that if a feast had no meaning apart from historical particulars, then there would no reason for us to celebrate it, just as I do not institute a feast to celebrate the fact that I ate breakfast on January 1st, 1990. In a similar way, in the second volume of his work Jesus of Nazareth, Joseph Ratzinger says about the resurrection of Jesus,

Now it must be acknowledged that if in Jesus’ Resurrection we were dealing simply with the miracle of a resuscitated corpse, it would ultimately be of no concern to us. For it would be no more important than the resuscitation of a clinically dead person through the art of doctors. For the world as such and for our human existence, nothing would have changed.

Ratzinger goes on to assert that the resurrection of Jesus changes the world in ways that are likely to be denied by unbelievers. And here there may be a real issue. Every feast and holiday is intended to celebrate universal truths, not merely historical particulars. But that does not necessarily imply that the purported universal truths are actually universal truths: they may be partial truths, or even complete falsehoods. And in that case, one might indeed question whether the feast should be celebrated at all.

One response is that the feast almost certainly has more than one meaning, and consequently one can concentrate on the true meanings. Thus Francis Hunt, in the quoted passage, gives his attention to things which will be likely to be accepted by unbelievers.

But I would argue instead that the principal meaning of Easter is actually true, even in a way which is accessible to unbelievers. Fr. Thomas Bolin, in a homily for one of the Sundays of Lent, explains the joy of Easter:

Today, the fourth Sunday of Lent, is traditionally called “Laetare Sunday”, for the introit of today’s Mass, which begins with the words “Laetare, Jerusalem.” This day is similar to “Gaudete Sunday”, the third Sunday of Advent. For these two Sundays, we wear rose vestments instead of violet, and each Sunday is around the middle of the season. Therefore, today, in the heart of Lent, we begin to anticipate the joy of Easter.

The texts of today’s liturgy express this joy in particular with the image of the joy of the Jerusalem freed from her oppressors. Not only the introit, but also the gradual, “Laetatus sum”, the tract, “Qui confidunt”, which the schola sang before the Gospel, and also the chant for communion, “Jerusalem quae aedificatur ut civitas” (meaning, “Jerusalem, which is built as a city”); all these make reference to Jerusalem and the joy of living there in peace and freedom.

St. Paul, in the first reading, explains that Jerusalem, the physical city, is not such a perfect and happy place. Instead, he says that the physical Jerusalem is a slave, while only “that Jerusalem which is above, is free” (Gal 4:26). Therefore, the true joy of Jerusalem is the happiness of the heavenly city. This joy is the same as that of Easter, which we eagerly anticipate, because with His death and resurrection, Jesus opened the gates of Paradise.

I have been in Jerusalem and can testify that St. Paul’s claims remain true to this day. Even if it is not “a slave” to the Romans, it remains a rather unhappy city. However, an objection might arise at his point. I claimed above that the meaning of Easter is accessible to unbelievers. But if the joy of Easter is the joy of the heavenly city, then it seems to be inaccessible to unbelievers, or at least to those who do not believe in the existence of heaven.

But even this depends on how you understand the heavenly Jerusalem itself. It is possible to look at this in the sense of ideal form which we strive to imitate as perfectly as possible. In this way, in chapter 6 of his work On the Perfection of the Spiritual Life, St. Thomas says that one should strive for heavenly virtue even in this life:

When St. Paul had said, “Not as though I had already attained, or were already perfect,” and, “but I follow after, if I may by any means lay hold,” he added shortly afterwards, “Let us therefore, as many as are perfect, be thus minded.” From these words we can see that although the perfection of the blessed is not possible to us in this life, we ought, to strive to imitate it as far as we can. And it is in this that the perfection of this life consists to which we are invited by the counsels.

For it is manifest that the human heart is more intensely drawn to one thing, to the degree that it is drawn back from many things. Thus the more a man is freed from the affection for temporal things, the more perfectly his mind will be borne to loving God. Hence St. Augustine says that “the desire of temporal things is the poison of charity; the growth of charity is the diminishment of cupidity, and the perfection of charity is no cupidity.” (Eighty-Three Questions, Book 83, Quest. 1). Therefore all the counsels, which invite us to perfection, aim at this, that man’s mind be turned away from affection to temporal objects, so that his mind may tend more freely to God, by contemplating him, loving him, and fulfilling his will.

It is possible to strive for perfection in this way whether or not “the perfection of the blessed” is something that exists in the real world. And it is possible for someone to view the perfection of the heavenly Jerusalem in a similar way, namely as an ideal form that the world strives for, but that it actually achieves only to a limited degree.

There are of course unbelievers who would deny even this sort of perfection, except as something that human beings invent for themselves. Richard Dawkins is a good example, since he asserts that reality is intrinsically “indifferent,” rather than ordered towards good. Someone who consistently holds such a position would indeed have no reason to celebrate Easter. But such a person equally would have no reason to do anything at all, since as I said in the linked post, if there is no purpose to life “at bottom,” there would likely be no purpose worth pursuing, even on the surface.

But in fact the world is ordered towards good, and tends to achieve it, although not perfectly, and it also tends to get better, as I have argued elsewhere. This implies that the joy of Easter has a meaning which is accessible to unbelievers, and can be a reason for them to celebrate the feast, much as Francis Hunt argues, although his argument is a bit vaguer. Of course, a believer is likely to respond that this would be a vastly diminished understanding of Easter. And this is true: as Hunt says, “I am aware that many believers may see my position as impoverished. If their belief should be true, then they are right.” But this is hardly a reason for the believer to say, “You aren’t allowed to celebrate Easter unless you believe all of it,” nor for the unbeliever to say, “Since I don’t think anything significant happened on Easter I’m not treating it as a special day.”

This is why, despite my personal opinions, I attended an Easter Vigil liturgy last night; why I just finished listening to a rendering of the Exultet; and why in general I am not embarrassed at all by the celebration of Easter.

In that spirit, happy Easter to all!

 

Settled Issues

In chapter 5 of his book Probability Theory: The Logic of Science, E. T. Jaynes discusses ESP:

I. J. Good (1950) has shown how we can use probability theory backwards to measure our own strengths of belief about propositions. For example, how strongly do you believe in extrasensory perception?

What probability would you assign to the hypothesis that Mr Smith has perfect extrasensory perception? More specifically, that he can guess right every time which number you have written down. To say zero is too dogmatic. According to our theory, this means that we are never going to allow the robot’s mind to be changed by any amount of evidence, and we don’t really want that. But where is our strength of belief in a proposition like this?

Our brains work pretty much the way this robot works, but we have an intuitive feeling for plausibility only when it’s not too far from 0 db. We get fairly definite feelings that something is more than likely to be so or less than likely to be so. So the trick is to imagine an experiment. How much evidence would it take to bring your state of belief up to the place where you felt very perplexed and unsure about it? Not to the place where you believed it – that would overshoot the mark, and again we’d lose our resolving power. How much evidence would it take to bring you just up to the point where you were beginning to consider the possibility seriously?

So, we consider Mr Smith, who says he has extrasensory perception (ESP), and we will write down some numbers from one to ten on a piece of paper and ask him to guess which numbers we’ve written down. We’ll take the usual precautions to make sure against other ways of finding out. If he guesses the first number correctly, of course we will all say ‘you’re a very lucky person, but I don’t believe you have ESP’. And if he guesses two numbers correctly, we’ll still say ‘you’re a very lucky person, but I still don’t believe you have ESP’. By the time he’s guessed four numbers correctly – well, I still wouldn’t believe it. So my state of belief is certainly lower than −40 db.

How many numbers would he have to guess correctly before you would really seriously consider the hypothesis that he has extrasensory perception? In my own case, I think somewhere around ten. My personal state of belief is, therefore, about −100 db. You could talk me into a ±10 db change, and perhaps as much as ±30 db, but not much more than that.

The idea is that after Mr. Smith guesses 7 to 13 numbers correctly (when by chance he should have a probability of 10% of guessing each one correctly), Jaynes will begin to think it reasonably likely that he has ESP. He notes that this is his subjective opinion, saying, “In my own case,” and “My personal state of belief.”

However, Jaynes follows this up by stating that if this happened in real life, he would not be convinced:

After further thought, we see that, although this result is correct, it is far from the whole story. In fact, if he guessed 1000 numbers correctly, I still would not believe that he has ESP, for an extension of the same reason that we noted in Chapter 4 when we first encountered the phenomenon of resurrection of dead hypotheses. An hypothesis A that starts out down at −100 db can hardly ever come to be believed, whatever the data, because there are almost sure to be alternative hypotheses (B1, B2,…) above it, perhaps down at −60 db. Then, when we obtain astonishing data that might have resurrected A, the alternatives will be resurrected instead.

In other words, Jaynes is saying, “This happened by chance,” and “Mr. Smith has ESP” are not the only possibilities. For example, it is possible that Mr. Smith has invented a remote MRI device, which he has trained to distinguish people’s thoughts about numbers, and he is receiving data on the numbers picked by means of an earbud. If the prior probability of this is higher than the prior probability that Mr. Smith has ESP, then Jaynes will begin to think this is a reasonable hypothesis, rather than coming to accept ESP.

This does not imply that Jaynes is infinitely confident that Mr. Smith does not have ESP, and in fact it does not invalidate his original estimate:

Now let us return to that original device of I. J. Good, which started this train of thought. After all this analysis, why do we still hold that naive first answer of −100 db for my prior probability for ESP, as recorded above, to be correct? Because Jack Good’s imaginary device can be applied to whatever state of knowledge we choose to imagine; it need not be the real one. If I knew that true ESP and pure chance were the only possibilities, then the device would apply and my assignment of −100 db would hold. But, knowing that there are other possibilities in the real world does not change my state of belief about ESP; so the figure of −100 db still holds.

He would begin to be convinced after about 10 numbers if he knew for a fact that chance and ESP were the only possibilities, and thus this is a good representation of how certain he is subjectively.

The fact of other possibilities also does not mean that it is impossible for Jaynes to be convinced, even in the real world, that some individual has ESP. But it does mean that this can happen only with great difficulty: essentially, he must be convinced that the other possibilities are even less likely than ESP. As Jaynes says,

Indeed, the very evidence which the ESP’ers throw at us to convince us, has the opposite effect on our state of belief; issuing reports of sensational data defeats its own purpose. For if the prior probability for deception is greater than that of ESP, then the more improbable the alleged data are on the null hypothesis of no deception and no ESP, the more strongly we are led to believe, not in ESP, but in deception. For this reason, the advocates of ESP (or any other marvel) will never succeed in persuading scientists that their phenomenon is real, until they learn how to eliminate the possibility of deception in the mind of the reader. As (5.15) shows, the reader’s total prior probability for deception by all mechanisms must be pushed down below that of ESP.

This is related to the grain of truth in Hume’s account of miracles. Hume’s basic point, that an account of a miracle could never be credible, is mistaken. But he is correct to say that the account would not be credible unless “these witnesses are mistaken or lying” has a lower prior probability than the prior probability of the miracle actually happening. His mistake is to suppose that this cannot happen in principle.

Something like this also happens with ordinary things that we are extremely sure about. For example, take your belief that the American War of Independence happened before the Civil War. You can imagine coming upon evidence that the Civil War happened first. Thus for example suppose you found a book by a historian arguing for this thesis. This would be evidence that the Civil War came first. But it would be very unpersuasive, and would change your mind little if at all, because the prior probability of “this is a work of fiction,” or indeed of “this a silly book arguing a silly thesis for personal reasons” is higher.

We could call this a “settled issue,” at least from your point of view (and in this case from the point of view of pretty much everyone). Not only do you believe that the War of Independence came first; it would be very difficult to persuade you otherwise, even if there were real evidence against your position, and this is not because you are being unreasonable. In fact, it would be unreasonable to be moved significantly by the evidence of that book arguing the priority of the Civil War.

Is it possible in principle to persuade you to change your mind? Yes. In principle this could happen bit by bit, by an accumulation of small pieces of evidence. You might read that book, and then learn that the author is a famous historian, and that he is completely serious (presumably he became famous before writing the book; otherwise he would instead be infamous.) And then you might find other items in favor of this theory, and find refutations of the apparently more likely explanations.

But in practice such a process is extremely unlikely. The most likely way you could change your mind about this would be by way of one large change. For example, you might wake up in a hospital tomorrow and be told that you had been suffering from a rare form of amnesia which does not remove a person’s past memories, but changes them into something different. You ask about the Civil War, and are told that everyone agrees that it happened before the War of Independence. People can easily give you dozens of books on the topic; you search online on the matter, and everything on the internet takes for granted that the Civil War came first. Likewise, everyone you talk to simply takes this for granted.

The reason that the “one big change” process is more likely than the “accumulation of small evidences” process is this: if we want to know what should persuade you that the Civil War came first, we are basically asking what the world would have to be like in order for it to be actually true that the Civil War came first. In such a world, your current belief is false. And in such a world it is simply much more likely that you have made one big mistake which resulted in your false belief about the Civil War, than that you have made lots of little mistakes which led to it.

 

Hume’s Error on Miracles

After his comparison with the idea of the Real Presence, Hume continues by saying that we should proportion our beliefs to the evidence for them:

Though experience be our only guide in reasoning concerning matters of fact; it must be acknowledged, that this guide is not altogether infallible, but in some cases is apt to lead us into errors. One, who in our climate, should expect better weather in any week of June than in one of December, would reason justly, and conformably to experience; but it is certain, that he may happen, in the event, to find himself mistaken. However, we may observe, that, in such a case, he would have no cause to complain of experience; because it commonly informs us beforehand of the uncertainty, by that contrariety of events, which we may learn from a diligent observation. All effects follow not with like certainty from their supposed causes. Some events are found, in all countries and all ages, to have been constantly conjoined together: Others are found to have been more variable, and sometimes to disappoint our expectations; so that, in our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence.
A wise man, therefore, proportions his belief to the evidence. In such conclusions as are founded on an infallible experience, he expects the event with the last degree of assurance, and regards his past experience as a full proof of the future existence of that event. In other cases, he proceeds with more caution: he weighs the opposite experiments: he considers which side is supported by the greater number of experiments: to that side he inclines, with doubt and hesitation; and when at last he fixes his judgement, the evidence exceeds not what we properly call probability. All probability, then, supposes an opposition of experiments and observations, where the one side is found to overbalance the other, and to produce a degree of evidence, proportioned to the superiority. A hundred instances or experiments on one side, and fifty on another, afford a doubtful expectation of any event; though a hundred uniform experiments, with only one that is contradictory, reasonably beget a pretty strong degree of assurance. In all cases, we must balance the opposite experiments, where they are opposite, and deduct the smaller number from the greater, in order to know the exact force of the superior evidence.

While Hume is right to say that convictions should in some way be proportionate to the evidence for them, we can already see here the cause of a serious error. As I have pointed out elsewhere, Hume does not have a developed mathematical theory of probability. Hence his talk of how one should “deduct the smaller number from the greater, in order to know the exact force of the superior evidence.” If one takes this literally, this would suggest that something with no experiments supporting it has a force of 0; something with 35 experiments supporting it and nothing against has a force of 35; something with 40 experiments supporting it and 5 against has the same force; and so on. All of this, of course, is evidently absurd.

He then brings up the example of the testimony of witnesses:

To apply these principles to a particular instance; we may observe, that there is no species of reasoning more common, more useful, and even necessary to human life, than that which is derived from the testimony of men, and the reports of eye-witnesses and spectators. This species of reasoning, perhaps, one may deny to be founded on the relation of cause and effect. I shall not dispute about a word. It will be sufficient to observe that our assurance in any argument of this kind is derived from no other principle than our observation of the veracity of human testimony, and of the usual conformity of facts to the reports of witnesses. It being a general maxim, that no objects have any discoverable connexion together, and that all the inferences, which we can draw from one to another, are founded merely on our experience of their constant and regular conjunction; it is evident, that we ought not to make an exception to this maxim in favour of human testimony, whose connexion with any event seems, in itself, as little necessary as any other. Were not the memory tenacious to a certain degree; had not men commonly an inclination to truth and a principle of probity; were they not sensible to shame, when detected in a falsehood: were not these, I say, discovered by experience to be qualities, inherent in human nature, we should never repose the least confidence in human testimony. A man delirious, or noted for falsehood and villainy, has no manner of authority with us.
And as the evidence, derived from witnesses and human testimony, is founded on past experience, so it varies with the experience, and is regarded either as a proof or a probability, according as the conjunction between any particular kind of report and any kind of object has been found to be constant or variable. There are a number of circumstances to be taken into consideration in all judgements of this kind; and the ultimate standard, by which we determine all disputes, that may arise concerning them, is always derived from experience and observation. Where this experience is not entirely uniform on any side, it is attended with an unavoidable contrariety in our judgements, and with the same opposition and mutual destruction of argument as in every other kind of evidence. We frequently hesitate concerning the reports of others. We balance the opposite circumstances, which cause any doubt or uncertainty; and when we discover a superiority on any side, we incline to it; but still with a diminution of assurance, in proportion to the force of its antagonist.
This contrariety of evidence, in the present case, may be derived from several different causes; from the opposition of contrary testimony; from the character or number of the witnesses; from the manner of their delivering their testimony; or from the union of all these circumstances. We entertain a suspicion concerning any matter of fact, when the witnesses contradict each other; when they are but few, or of a doubtful character; when they have an interest in what they affirm; when they deliver their testimony with hesitation, or on the contrary, with too violent asseverations. There are many other particulars of the same kind, which may diminish or destroy the force of any argument, derived from human testimony.
Suppose, for instance, that the fact, which the testimony endeavours to establish, partakes of the extraordinary and the marvellous; in that case, the evidence, resulting from the testimony, admits of a diminution, greater or less, in proportion as the fact is more or less unusual. The reason why we place any credit in witnesses and historians, is not derived from any connexion, which we perceive à priori, between testimony and reality, but because we are accustomed to find a conformity between them. But when the fact attested is such a one as has seldom fallen under our observation, here is a contest of two opposite experiences; of which the one destroys the other, as far as its force goes, and the superior can only operate on the mind by the force, which remains. The very same principle of experience, which gives us a certain degree of assurance in the testimony of witnesses, gives us also, in this case, another degree of assurance against the fact, which they endeavour to establish; from which contradiction there necessarily arises a counterpoize, and mutual destruction of belief and authority.
I should not believe such a story were it told me by Cato, was a proverbial saying in Rome, even during the lifetime of that philosophical patriot. The incredibility of a fact, it was allowed, might invalidate so great an authority.
The Indian prince, who refused to believe the first relations concerning the effects of frost, reasoned justly; and it naturally required very strong testimony to engage his assent to facts, that arose from a state of nature, with which he was unacquainted, and which bore so little analogy to those events, of which he had had constant and uniform experience. Though they were not contrary to his experience, they were not conformable to it.

While we might disagree that someone would be reasonable in refusing to accept testimony concerning the effects of frost, Hume’s general points here are fairly reasonable.

But when he attempts to apply to this miracles, he basically attempts to reason from the invalid mathematical points in the previous text:

But in order to increase the probability against the testimony of witnesses, let us suppose, that the fact, which they affirm, instead of being only marvellous, is really miraculous; and suppose also, that the testimony considered apart and in itself, amounts to an entire proof; in that case, there is proof against proof, of which the strongest must prevail, but still with a diminution of its force, in proportion to that of its antagonist.
A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined. Why is it more than probable, that all men must die; that lead cannot, of itself, remain suspended in the air; that fire consumes wood, and is extinguished by water; unless it be, that these events are found agreeable to the laws of nature, and there is required a violation of these laws, or in other words, a miracle to prevent them? Nothing is esteemed a miracle, if it ever happen in the common course of nature. It is no miracle that a man, seemingly in good health, should die on a sudden: because such a kind of death, though more unusual than any other, has yet been frequently observed to happen. But it is a miracle, that a dead man should come to life; because that has never been observed in any age or country. There must, therefore, be a uniform experience against every miraculous event, otherwise the event would not merit that appellation. And as a uniform experience amounts to a proof, there is here a direct and full proof, from the nature of the fact, against the existence of any miracle; nor can such a proof be destroyed, or the miracle rendered credible, but by an opposite proof, which is superior.
The plain consequence is (and it is a general maxim worthy of our attention), ‘that no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavors to establish; and even in that case there is a mutual destruction of arguments, and the superior only gives us an assurance suitable to that degree of force, which remains, after deducting the inferior.’ When anyone tells me, that he saw a dead man restored to life, I immediately consider with myself, whether it be more probable, that this person should either deceive or be deceived, or that the fact, which he relates, should really have happened. I weigh the one miracle against the other; and according to the superiority, which I discover, I pronounce my decision, and always reject the greater miracle. If the falsehood of his testimony would be more miraculous, than the event which he relates; then, and not till then, can he pretend to command my belief or opinion.

There are various ways to read this, but each way leads to problems. Hume has told himself that he believes that he has found a conclusive proof that accounts of miracles should never be accepted; and this implies that he must be saying that his condition, that the testimony should “be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavors to establish,” can never be satisfied.

But there is no reasonable understanding where this condition can never be satisfied. Hume seems to be equating “more miraculous” with “less probable,” but there is no degree of probability that could not be established by witnesses in principle. Even if each witness has only a small chance of telling the truth, multiple independent witnesses could in principle establish any degree of probability whatsoever.

The basic problem here seems to be Hume’s mathematically incorrect understanding of probability. If something has never been seen to happen, he says, this is a full proof that it cannot happen. Thus he seems to imply that there is a 0% chance of it happening. But this is evidently unreasonable. In reality, of course, we often see particular things happen which never happened before. And similarly, it is simply not true that a miracle is only called a miracle because it “has never been observed in any age or country.” There have been many reports, in many ages and many countries, of dead people coming to life again. So the only way Hume could say that a dead person coming to life is a miracle in this sense, is by assuming that all of these reports are false. This is simply to assume what he is trying to prove, and in any case we think that resurrection is a miracle whether or not these reports are true. In other words, to say that resurrection is a miracle is not to say that these reports are false, but that if they are true, they are reports of miracles.

Taken in another way, Hume seems to be saying, “A miracle requires a suspension of natural laws. But false testimony does not. Therefore if we have the choice of believing that there was a miracle or of believing that there was false testimony, we should always choose to believe that there was false testimony.” The problem is that, again, if you evaluate this in terms of probabilities, the suspension of natural laws might well be more probable than a particular possibility which does not suspend natural laws. If someone predicts the result of a coin flip 100,000 times in a row, it does not violate natural laws to think that this happened by chance, with a fair coin. But it is much more probable that natural laws were violated, than that this happened by chance with a fair coin.

While it would only relate to Hume personally, we might also note that according to Hume, induction cannot even establish a probability, let alone a necessity.  So according to his position, the experience of dead people remaining dead does not make it improbable that one would rise, let alone excluding it as impossible.

Hume himself seems to sense that there is something wrong with his position, even if he cannot quite work out what it is, again probably on account of the lack of a mathematical theory of probability. Consequently he adds a number of arguments:

For first, there is not to be found, in all history, any miracle attested by a sufficient number of men, of such unquestioned good sense, education, and learning, as to secure us against all delusion in themselves; of such undoubted integrity, as to place them beyond all suspicion of any design to deceive others; of such credit and reputation in the eyes of mankind, as to have a great deal to lose in case of their being detected in any falsehood; and at the same time, attesting facts performed in such a public manner and in so celebrated a part of the world, as to render the detection unavoidable: all which circumstances are requisite to give us a full assurance in the testimony of men.
Secondly. We may observe in human nature a principle which, if strictly examined, will be found to diminish extremely the assurance, which we might, from human testimony, have in any kind of prodigy. The maxim, by which we commonly conduct ourselves in our reasonings, is, that the objects, of which we have no experience, resembles those, of which we have; that what we have found to be most usual is always most probable; and that where there is an opposition of arguments, we ought to give the preference to such as are founded on the greatest number of past observations. But though, in proceeding by this rule, we readily reject any fact which is unusual and incredible in an ordinary degree; yet in advancing farther, the mind observes not always the same rule; but when anything is affirmed utterly absurd and miraculous, it rather the more readily admits of such a fact, upon account of that very circumstance, which ought to destroy all its authority. The passion of surprise and wonder, arising from miracles, being an agreeable emotion, gives a sensible tendency towards the belief of those events, from which it is derived. And this goes so far, that even those who cannot enjoy this pleasure immediately, nor can believe those miraculous events, of which they are informed, yet love to partake of the satisfaction at second-hand or by rebound, and place a pride and delight in exciting the admiration of others.
With what greediness are the miraculous accounts of travellers received, their descriptions of sea and land monsters, their relations of wonderful adventures, strange men, and uncouth manners? But if the spirit of religion join itself to the love of wonder, there is an end of common sense; and human testimony, in these circumstances, loses all pretensions to authority. A religionist may be an enthusiast, and imagine he sees what has no reality: he may know his narrative to be false, and yet persevere in it, with the best intentions in the world, for the sake of promoting so holy a cause: or even where this delusion has not place, vanity, excited by so strong a temptation, operates on him more powerfully than on the rest of mankind in any other circumstances; and self-interest with equal force. His auditors may not have, and commonly have not, sufficient judgement to canvass his evidence: what judgement they have, they renounce by principle, in these sublime and mysterious subjects: or if they were ever so willing to employ it, passion and a heated imagination disturb the regularity of its operations, their credulity increases his impudence: and his impudence overpowers their credulity.
Eloquence, when at its highest pitch, leaves little room for reason or reflection; but addressing itself entirely to the fancy or the affections, captivates the willing hearers, and subdues their understanding. Happily, this pitch is seldom attains. But what a Tully or a Demosthenes could scarcely effect over a Roman or Athenian audience, every Capuchin, every itinerant or stationary teacher can perform over the generality of mankind, and in a higher degree, by touching such gross and vulgar passions.
The many instances of forged miracles, and prophecies, and supernatural events, which, in all ages, have either been detected by contrary evidence, or which detect themselves by their absurdity, prove sufficiently the strong propensity of mankind to the extraordinary and the marvellous, and ought reasonably to beget a suspicion against all relations of this kind. This is our natural way of thinking, even with regard to the most common and most credible events. For instance: There is no kind of report which rises so easily, and spreads so quickly, especially in country places and provincial towns, as those concerning marriages; insomuch that two young persons of equal condition never see each other twice, but the whole neighbourhood immediately join them together. The pleasure of telling a piece of news so interesting, of propagating it, and of being the first reporters of it, spreads the intelligence. And this is so well known, that no man of sense gives attention to these reports, till he find them confirmed by some greater evidence. Do not the same passions, and others still stronger, incline the generality of mankind to believe and report, with the greatest vehemence and assurance, all religious miracles?
Thirdly. It forms a strong presumption against all supernatural and miraculous relations, that they are observed chiefly to abound among ignorant and barbarous nations; or if a civilized people has ever given admission to any of them, that people will be found to have received them from ignorant and barbarous ancestors, who transmitted them with that inviolable sanction and authority, which always attend received opinions. When we peruse the first histories of all nations, we are apt to imagine ourselves transported into some new world; where the whole frame of nature is disjointed, and every element performs its operations in a different manner, from what it does at present. Battles, revolutions, pestilence, famine and death, are never the effect of those natural causes, which we experience. Prodigies, omens, oracles, judgements, quite obscure the few natural events, that are intermingled with them. But as the former grow thinner every page, in proportion as we advance nearer the enlightened ages, we soon learn, that there is nothing mysterious or supernatural in the case, but that all proceeds from the usual propensity of mankind towards the marvellous, and that, though this inclination may at intervals receive a check from sense and learning, it can never be thoroughly extirpated from human nature.
It is strange, a judicious reader is apt to say, upon the perusal of these wonderful historians, that such prodigious events never happen in our days. But it is nothing strange, I hope, that men should lie in all ages. You must surely have seen instances enough of that frailty. You have yourself heard many such marvellous relations started, which, being treated with scorn by all the wise and judicious, have at last been abandoned even by the vulgar. Be assured, that those renowned lies, which have spread and flourished to such a monstrous height, arose from like beginnings; but being sown in a more proper soil, shot up at last into prodigies almost equal to those which they relate.

Hume is making some reasonable points here. But note that all of these things are contingent. They could have been otherwise in general, and they might well be otherwise in particular cases, even actual ones. Consequently they cannot possibly amount to a full proof that miraculous accounts should not be accepted. The fact that Hume feels the need to point to these contingent facts shows that at some level he is aware of the fact that his argument is not conclusive, although he wishes it to be.

In the end, Hume’s argument does not establish anything, but only expresses his own incredulity, as in this example:

There is also a memorable story related by Cardinal de Retz, which may well deserve our consideration. When that intriguing politician fled into Spain, to avoid the persecution of his enemies, he passed through Saragossa, the capital of Arragon, where he was shewn, in the cathedral, a man, who had served seven years as a doorkeeper, and was well known to every body in town, that had ever paid his devotions at that church. He had been seen, for so long a time, wanting a leg; but recovered that limb by the rubbing of holy oil upon the stump; and the cardinal assures us that he saw him with two legs. This miracle was vouched by all the canons of the church; and the whole company in town were appealed to for a confirmation of the fact; whom the cardinal found, by their zealous devotion, to be thorough believers of the miracle. Here the relater was also contemporary to the supposed prodigy, of an incredulous and libertine character, as well as of great genius; the miracle of so singular a nature as could scarcely admit of a counterfeit, and the witnesses very numerous, and all of them, in a manner, spectators of the fact, to which they gave their testimony. And what adds mightily to the force of the evidence, and may double our surprise on this occasion, is, that the cardinal himself, who relates the story, seems not to give any credit to it, and consequently cannot be suspected of any concurrence in the holy fraud. He considered justly, that it was not requisite, in order to reject a fact of this nature, to be able accurately to disprove the testimony, and to trace its falsehood, through all the circumstances of knavery and credulity which produced it. He knew, that, as this was commonly altogether impossible at any small distance of time and place; so was it extremely difficult, even where one was immediately present, by reason of the bigotry, ignorance, cunning, and roguery of a great part of mankind. He therefore concluded, like a just reasoner, that such an evidence carried falsehood upon the very face of it, and that a miracle, supported by any human testimony, was more properly a subject of derision than of argument.

This is a distorted account of the miracle of Calanda. Ironically, Hume’s position is actually supported to some extent by the errors contained in his own account of the miracle: we cannot “trace its falsehood,” in the sense that we cannot determine whether the account has been distorted by Hume himself, by the Cardinal, by the residents of Zaragoza, or by others, or some combination of these, but it is easy enough to determine the fact that it has been so distorted. Nevertheless, Hume is not proving anything here, but simply asserting that he would not believe in a miracle no matter how good the testimony brought in its favor.

This is not a reasonable attitude, but sheer stubbornness.

How Not to Love the Truth

Since when you are thinking about yourself you will come to the same conclusion regardless of the truth, let’s talk about someone else. Suppose someone says this:

I have the Ultimate Theory of Reality. It is true and absolutely certain. Not only is it true, but there is not even the slightest bit of evidence against it. This is not an exaggeration. All the evidence in the world favors it. No one has ever mentioned even a single fact that stands against it, and all the people in the world who disagree with it disagree with it for emotional reasons alone. And if you hold the Ultimate Theory, you should never change your mind about it no matter what happens. If you find someone who says that he used to believe the Ultimate Theory but no longer does, he never really believed it in the first place. Finally, per impossibile, if the Ultimate Theory turned out to be false, there would be no reason to change my mind, because nothing would matter anymore.

Naturally, this is not an actual quotation. But neither is it a caricature. Although I will not link to the original, it is based on an actual opinion written by a real blogger not that long ago, and every point of it is a fair representation of what he actually said. There are a number of errors here:

  1. The claim to absolute certainty about his opinion.
  2. The claim that all of the evidence favors his opinion.
  3. The claim that he should never change his mind under any circumstances.
  4. The claim that someone could not hold his opinion and then change his mind.
Each of these claims indicates a lack of love of truth in relation to the opinion in question, or at any rate another love which takes precedence over the love of truth. They do this by showing that the person is attached to his opinion as this particular opinion, regardless of whether it is true. And the absolute character of the claims, in this particular example, comes close to showing a complete absence of the love of truth, relative to the particular claim. The first three claims do this in a somewhat evident manner, namely by indicating that the person would be unwilling to change his mind even if he were wrong. The fourth indicates that takes pride in his attachment and considers it good and reasonable: not only does he fail to love the truth of the matter, but he loves his own failure to love the truth. And all of these things are the case whether or not the Ultimate Theory is actually true.
Finally, there is a fifth claim, which I did not include in the list of errors because in principle it could be true (it was in fact false in the case in question.) He claims that if he were wrong, there would be no reason to change his mind, since nothing would matter anymore. In principle, this could be true. If “good and bad do not exist,” is true, then it is not bad to believe that they do exist. If “truth is bad and falsehood is good” is true, then it is good to say that truth is good, and bad to say that it is bad. And if it is true that “nothing matters” then it does not matter if I say that something matters.
But apart from such obvious examples, the claim is a danger signal relative to the love of truth, because again it indicates an attachment to a particular opinion that is unrelated to its truth or falsity. Just as the one who loves sweet wine loves sweetness, not wine, if he would no longer love the wine without sweetness, so one who would not love the truth if it were different from the opinion he currently holds, does not love truth but his opinion, even if his opinion is true.
This idealized example (again, however, a fair description of a real opinion) shows us how not to love the truth. The closer we are, in theory or in practice, to making these kinds of claims about our own opinions, the less likely it is that we actually love the truth relative to those opinions. Unfortunately, however, just as a person might believe himself to be a lover of truth without being one,  a person might suppose that he does not fall into these patterns of thinking, even while falling into them.

Do I Really Want To Know?

Some days ago I asked how we can determine whether we really love the truth or not. Bryan’s Caplan’s account of preferences over beliefs and rational irrationality indicates there may be an additional impediment to answering this question correctly, besides the factors mentioned in the first post. I may care more or less about the truth about various issues, especially depending on how they relate with other things I care about. Now consider the difference between “I have a deep love for the truth,” and “I don’t care much about the truth.”

For most people, the former statement is likely to appear attractive, and the latter unattractive. Let’s suppose we are trying to determine which one is actually true. If the first one is true, then we would care about the truth about ourselves, and we would make a decent effort to determine the truth, presumably arriving at the conclusion that the first is true (since it is true by hypothesis.)

But suppose the second is true. In that case, we are unlikely to make a great effort to determine the actual truth. Instead, we are likely to believe the more attractive opinion, namely the first, unless the costs of believing this are too high.

In principle, believing that I have a deep love for truth when in fact I do not could have a very high cost indeed. But in practice this would be by a very circuitous route, and frequently the costs would not be immediate or apparent in any way. Consequently someone who does not care much about the truth is likely to believe that he does care a lot, and is only likely to change his mind when the costs of his error become apparent, just like the person who becomes uncertain when he is offered a bet. Under normal circumstances, then, most people will hold the first belief, regardless of whether the first or the second is actually true.

 

Rational Irrationality

After giving reasons for thinking that people have preferences over beliefs, Bryan Caplan presents his model of rational irrationality, namely the factors that determine whether or not people give in to such preferences or resist them.

In extreme cases, mistaken beliefs are fatal. A baby-proofed house illustrates many errors that adults cannot afford to make. It is dangerous to think that poisonous substances are candy. It is dangerous to reject the theory of gravity at the top of the stairs. It is dangerous to hold that sticking forks in electrical sockets is harmless fun.

But false beliefs do not have to be deadly to be costly. If the price of oranges is 50 cents each, but you mistakenly believe it is a dollar, you buy too few oranges. If bottled water is, contrary to your impressions, neither healthier nor better-tasting than tap water, you may throw hundreds of dollars down the drain. If your chance of getting an academic job is lower than you guess, you could waste your twenties in a dead-end Ph.D. program.

The cost of error varies with the belief and the believer’s situation. For some people, the belief that the American Civil War came before the American Revolution would be a costly mistake. A history student might fail his exam, a history professor ruin his professional reputation, a Civil War reenactor lose his friends’ respect, a public figure face damaging ridicule.

Normally, however, a firewall stands between this mistake and “real life.” Historical errors are rarely an obstacle to wealth, happiness, descendants, or any standard metric of success. The same goes for philosophy, religion, astronomy, geology, and other “impractical” subjects. The point is not that there is no objectively true answer in these fields. The Revolution really did precede the Civil War. But your optimal course of action if the Revolution came first is identical to your optimal course if the Revolution came second.

To take another example: Think about your average day. What would you do differently if you believed that the earth began in 4004 B.C., as Bishop Ussher infamously maintained? You would still get out of bed, drive to work, eat lunch, go home, have dinner, watch TV, and go to sleep. Ussher’s mistake is cheap.

Virtually the only way that mistakes on these questions injure you is via their social consequences. A lone man on a desert island could maintain practically any historical view with perfect safety. When another person washes up, however, there is a small chance that odd historical views will reduce his respect for his fellow islander, impeding cooperation. Notice, however, that the danger is deviance, not error. If everyone else has sensible historical views, and you do not, your status may fall. But the same holds if everyone else has bizarre historical views and they catch you scoffing.

To use economic jargon, the private cost of an action can be negligible, though its social cost is high. Air pollution is the textbook example. When you drive, you make the air you breathe worse. But the effect is barely perceptible. Your willingness to eliminate your own emissions might be a tenth of a cent. That is the private cost of your pollution. But suppose that you had the same impact on the air of 999,999 strangers. Each disvalues your emissions by a tenth of a cent too. The social cost of your activity—the harm to everyone including yourself—is $1,000, a million times the private cost.

Caplan thus makes the general points that our beliefs on many topics cannot hurt us directly, and frequently can do so only by means of social consequences. He adds the final point that the private cost of an action—or in this case a belief—may be very different from the total cost.

Finally, Caplan presents his economic model of rational irrationality:

Two forces lie at the heart of economic models of choice: preferences and prices. A consumer’s preferences determine the shape of his demand curve for oranges; the market price he faces determines where along that demand curve he resides. What makes this insight deep is its generality. Economists use it to analyze everything from having babies to robbing banks.

Irrationality is a glaring exception. Recognizing irrationality is typically equated with rejecting economics. A “logic of the irrational” sounds self-contradictory. This chapter’s central message is that this reaction is premature. Economics can handle irrationality the same way it handles everything: preferences and prices. As I have already pointed out:

  • People have preferences over beliefs: A nationalist enjoys the belief that foreign-made products are overpriced junk; a surgeon takes pride in the belief that he operates well while drunk.
  • False beliefs range in material cost from free to enormous: Acting on his beliefs would lead the nationalist to overpay for inferior goods, and the surgeon to destroy his career.

Snapping these two building blocks together leads to a simple model of irrational conviction. If agents care about both material wealth and irrational beliefs, then as the price of casting reason aside rises, agents consume less irrationality. I might like to hold comforting beliefs across the board, but it costs too much. Living in a Pollyanna dreamworld would stop be from coping with my problems, like that dead tree in my backyard that looks like it is going to fall on my house.

As I said in the last post, one reason why people argue against such a view is that it can seem psychologically implausible. Caplan takes notes of the same fact:

Arguably the main reason why economists have not long since adopted an approach like mine is that it seems psychologically implausible. Rational irrationality appears to map an odd route to delusion:

Step 1: Figure out the truth to the best of your ability.

Step 2: Weigh the psychological benefits of rejecting the truth against its material costs.

Step 3: If the psychological benefits outweigh the material costs, purge the truth from your mind and embrace error.

The psychological plausibility of this stilted story is underrated.

Of course, this process is not so conscious and explicit in reality, and this is why the above seems so implausible. Caplan presents the more realistic version:

But rational irrationality does not require Orwellian underpinnings. The psychological interpretation can be seriously toned down without changing the model. Above all, the steps should be conceived as tacit. To get in your car and drive away entails a long series of steps—take out your keys, unlock and open the door, sit down, put the key in the ignition, and so on. The thought processes behind these steps are rarely explicit. Yet we know the steps on some level, because when we observe a would-be driver who fails to take one—by, say, trying to open a locked door without using his key—it is easy to state which step he skipped.

Once we recognize that cognitive “steps” are usually tacit, we can enhance the introspective credibility of the steps themselves. The process of irrationality can be recast:

Step 1: Be rational on topics where you have no emotional attachment to a particular answer.

Step 2: On topics where you have an emotional attachment to a particular answer, keep a “lookout” for questions where false beliefs imply a substantial material cost for you.

Step 3: If you pay no substantial material costs of error, go with the flow; believe whatever makes you feel best.

Step 4: If there are substantial material costs of error, raise your level of intellectual self-discipline in order to become more objective.

Step 5: Balance the emotional trauma of heightened objectivity—the progressive shattering of your comforting illusions—against the material costs of error.

There is no need to posit that people start with a clear perception of the truth, then throw it away. The only requirement is that rationality remain on “standby,” ready to engage when error is dangerous.

Caplan offers various examples of this process happening in practice. I will include here only the last example:

Want to bet? We encounter the price-sensitivity of irrationality whenever someone unexpectedly offers us a bet based on our professed beliefs. Suppose you insist that poverty in the Third World is sure to get worse in the next decade. A challenger immediately retorts, “Want to bet? If you’re really ‘sure,’ you won’t mind giving me ten-to-one odds.” Why are you unlikely to accept this wager? Perhaps you never believed your own words; your statements were poetry—or lies. But it is implausible to tar all reluctance to bet with insincerity. People often believe that their assertions are true until you make them “put up or shut up.” A bet moderates their views—that is, changes their minds—whether or not they retract their words.

Bryan Caplan’s account is very closely related to what I have argued elsewhere, namely that people are more influenced by non-truth-related motives in areas remote from the senses. Caplan’s account explains that a large part of the reason for this is simply that being mistaken is less harmful in these areas (at least in a material sense), and consequently that people care less about whether their views in these areas are true, and care more about other factors. This also explains why the person who is offered a bet in the example changes his mind: this is not simply explained by whether or not the truth of the matter can be determined by sensible experience, but by whether a mistaken opinion in this particular case is likely to cause harm or not.

Nonetheless, even if you do care about truth because error can harm you, this too is a love of sweetness, not of truth.

Bryan Caplan on Preferences Over Beliefs

Responding to the criticism mentioned in the previous post, Caplan begins by noting that it is quite possible to observe preferences:

I observe one person’s preferences every day—mine. Within its sphere I trust my introspection more than I could ever trust the work of another economist. Introspection tells me that I am getting hungry, and would be happy to pay a dollar for an ice cream bar. If anything qualifies as “raw data,” this does. Indeed, it is harder to doubt than “raw data” that economists routinely accept—like self-reported earnings.

One thing my introspection tells me is that some beliefs are more emotionally appealing than their opposites. For example, I like to believe that I am right. It is worse to admit error, or lose money because of error, but error is disturbing all by itself. Having these feelings does not imply that I indulge them—no more than accepting money from a source with an agenda implies that my writings are insincere. But the temptation is there.

After this discussion of his own experience, he considers the experience of others:

Introspection is a fine way to learn about your own preferences. But what about the preferences of others? Perhaps you are so abnormal that it is utterly misleading to extrapolate from yourself to the rest of humanity. The simplest way to check is to listen to what other people say about their preferences.

I was once at a dinner with Gary Becker where he scoffed at this idea. His position, roughly, was, “You can’t believe what people say,” though he still paid attention when the waiter named the house specialties. Yes, there is a sound core to Becker’s position. People fail to reflect carefully. People deceive. But contrary to Becker, these are not reasons to ignore their words. We should put less weight on testimony when people speak in haste, or have an incentive to lie. But listening remains more informative than plugging your ears. After all, human beings can detect lies as well as tell them. Experimental psychology documents that liars sometimes give themselves away with demeanor or inconsistencies in their stories.

Once we take the testimony of mankind seriously, evidence of preferences over beliefs abounds. People can’t shut up about them. Consider the words of philosopher George Berkeley:

“I can easily overlook any present momentary sorrow when I reflect that it is in my power to be happy a thousand years hence. If it were not for this thought I had rather be an oyster than a man.”

Paul Samuelson himself revels in the Keynesian revelation, approvingly quoting Wordsworth to capture the joy of the General Theory: “Bliss was it in that dawn to be alive, but to be young was very heaven!”

Many autobiographies describe the pain of abandoning the ideas that once gave meaning to the author’s life. As Whittaker Chambers puts it:

“So great an effort, quite apart from its physical and practical hazards, cannot occur without a profound upheaval of the spirit. No man lightly reverses the faith of an adult lifetime, held implacably to the point of criminality. He reverses it only with a violence greater than the faith he is repudiating.”

No wonder that—in his own words—Chambers broke with Communism “slowly, reluctantly, in agony.” For Arthur Koestler, deconversion was “emotional harakiri.” He adds, “Those who have been caught by the great illusion of our time, and have lived though its moral and intellectual debauch, either give themselves up to a new addiction of the opposite type, or are condemned to pay with a lifelong hangover.” Richard Write laments, “I knew in my heart that I should never be able to feel with that simple sharpness about life, should never again express such passionate hope, should never again make so total a commitment of faith.”

The desire for “hope and illusion” plays a role even in mental illness. According to his biographer, Nobel Prize winner and paranoid schizophrenic John Nash often preferred his fantasy world—where he was a “Messianic godlike figure”—to harsh reality:

“For Nash, the recovery of everyday thought processes produced a sense of diminution and loss…. He refers to his remissions not as joyful returns to a healthy state, but as ‘interludes, as it were, of enforced rationality.'”

One criticism here might go as follows. Yes, Caplan has done a fine job of showing that people find some beliefs attractive and others unattractive, that some beliefs make them happy and some unhappy. But like C.S. Lewis, one can argue that this does not imply that this is why they hold those beliefs. It is likely enough that they have some real reasons as well, and this means that their preferences are irrelevant.

One basis for this objection is probably the idea that sitting down and choosing to believe something seems psychologically implausible. But it does not have to happen so explicitly, even though this is more possible than people might think. The fact that such preferences can be felt as “temptations,” as Caplan puts it in describing his own experience, is an indication that it is entirely possible to give in to the temptation or to resist it, and thus that we can choose our beliefs in effect, even if this is not an explicit thought.

We could compare such situations to the situation of someone addicted to smoking or drinking. Let’s suppose they are trying to get over it, but constantly falling back into the behavior. It may be psychologically implausible to assert, “He says he wants to get over it, but he is just faking. He actually prefers to remain addicted.” But this does not change the fact that every time he goes to the store to buy cigarettes, every time he takes one out to light it, every time he steps outside for a smoke, he exercises his power of choice. In the same way, we determine our beliefs by concrete choices, even though in many cases the idea that the person could have simply decided to choose the opposite belief may be implausible. I have discussed this kind of thing earlier, as for example here. When we are engaged in an argument with someone, and they seem to be getting the better of the argument, it is one choice if we say, “You’re probably right,” and another choice if we say, “You’re just wrong, but you’re clearly incapable of understanding the truth of the matter…” In any case it is certainly a choice, even if it does not feel like one, just as the smoker or the alcoholic may not feel like he has a choice about smoking and drinking.

Caplan has a last consideration:

If neither way of verifying the existence of preferences over beliefs appeals to you, a final one remains. Reverse the direction of reasoning. Smoke usually means fire. The more bizarre a mistake is, the harder it is to attribute to lack of information. Suppose your friend thinks he is Napoleon. It is conceivable that he got an improbable coincidence of misleading signals sufficient to convince any of us. But it is awfully suspicious that he embraces the pleasant view that he is a world-historic figure, rather than, say, Napoleon’s dishwasher. Similarly, suppose an adult sees trade as a zero-sum game. Since he experiences the opposite every day, it is hard to blame his mistake on “lack of information.” More plausibly, like blaming your team’s defeat on cheaters, seeing trade as disguised exploitation soothes those who dislike the market’s outcome.

It is unlikely that Bryan Caplan means to say your friend here is wicked rather than insane. Clearly someone living in the present who believes that he is Napoleon is insane, in the sense that his mind is not working normally. But Caplan’s point is that you cannot simply say, “His mind is not working normally, and therefore he holds an arbitrary belief with no relationship with reality,” but instead he holds a belief which includes something which many people would like to think, namely, “I am a famous and important person,” but which most ordinary people do not in fact think, because it is obviously false (in most cases.) So one way that the person’s mind works differently is that reality doesn’t have as much power to prevent him from holding attractive beliefs as for normal people, much like the case of John Nash as described by Caplan. But the fact that some beliefs are attractive is not a way in which he differs. It is a way in which he is like all of us.

The point about trade is that everyone who buys something at a store believes that he is making himself better off by his purchase, and knows that he makes the store better off as well. So someone who says that trade is zero-sum is contradicting this obvious fact; his claim cannot be due to a lack of evidence regarding the mutual utility of trade.

Love of Truth and Love of Self

Love of self is natural and can extend to almost any aspect of ourselves, including to our beliefs. In other words, we tend to love our beliefs because they are ours. This is a kind of “sweetnesss“. As suggested in the linked post, since we believe that our beliefs are true, it is not easy to distinguish between loving our beliefs for the sake of truth, and loving them because they are ours. But these are two different things: the first is the love of truth, and the second is an aspect of love of self.

Just as we love ourselves, we love the wholes of which we are parts: our family, our country, our religious communities, and so on. These are better than pure love of self, but they too can represent a kind of sweetness: if we love of our beliefs because they are the beliefs of our family, of our friends, of our religious and political communities, or because they are part of our worldview, none of these things is the love of truth, whether or not the beliefs are actually true.

This raises two questions: first, how do we know whether we are acting out of the love of truth, or out of some other love? And second, if there is a way to answer the first question, what can we do about it?

These questions are closely related to a frequent theme of this blog, namely voluntary beliefs, and the motives for these beliefs. Bryan Caplan, in his book The Myth of the Rational Voter, discusses these things under the name of “preferences over beliefs”:

The desire for truth can clash with other motives. Material self-interest is the leading suspect. We distrust salesmen because they make more money if they shade the truth. In markets for ideas, similarly, people often accuse their opponents of being “bought,” their judgment corrupted by a flow of income that would dry up if they changed their minds. Dasgupta and Stiglitz deride the free-market critique of antitrust policy as “well-funded” but “not well-founded.” Some accept funding from interested parties, then bluntly speak their minds anyway. The temptation, however, is to balance being right and being rich.

Social pressure for conformity is another force that conflicts with truth-seeking. Espousing unpopular views often transforms you into an unpopular person. Few want to be pariahs, so they self-censor. If pariahs are less likely to be hired, conformity blends into conflict of interest. However, even bereft of financial consequences, who wants to be hated? The temptation is to balance being right and being liked.

But greed and conformism are not the only forces at war with truth. Human beings also have mixed cognitive motives. One of our goals is to reach correct answers in order to take appropriate action, but that is not the only goal of our thought. On many topics, one position is more comforting, flattering, or exciting, raising the danger that our judgment will be corrupted not by money or social approval, but by our own passions.

Even on a desert isle, some beliefs make us feel better about ourselves. Gustave Le Bon refers to “that portion of hope and illusion without which [men] cannot live.” Religion is the most obvious example. Since it is often considered rude to call attention to the fact, let Gaetano Mosca make the point for me:

“The Christian must be enabled to think with complacency that everybody not of the Christian faith will be damned. The Brahman must be given grounds for rejoicing that he alone is descended from the head of Brahma and has the exalted honor of reading the sacred books. The Buddhist must be taught highly to prize the privilege he has of attaining Nirvana soonest. The Mohammedan must recall with satisfaction that he alone is a true believer, and that all others are infidel dogs in this life and tormented dogs in the next. The radical socialist must be convinced that all who do not think as he does are either selfish, money-spoiled bourgeois or ignorant and servile simpletons. These are all examples of arguments that provide for one’s need of esteeming one’s self and one’s own religion or convictions and at the same time for the need of despising and hating others.”

Worldviews are more a mental security blanket than a serious effort
to understand the world: “Illusions endure because illusion is a need
for almost all men, a need they feel no less strongly than their material needs.” Modern empirical work suggests that Mosca was on to something: The religious consistently enjoy greater life satisfaction. No wonder human beings shield their beliefs from criticism, and cling to them if counterevidence seeps through their defenses.

Most people find the existence of mixed cognitive motives so obvious
that “proof” is superfluous. Jost and his coauthors casually remark in the Psychological Bulletin that “Nearly everyone is aware of the possibility that people are capable of believing what they want to believe, at least within certain limits.” But my fellow economists are unlikely to sign off so easily. If one economist tells another, “Your economics is just a religion,” the allegedly religious economist normally takes the distinction between “emotional ideologue” and “dispassionate scholar” for granted, and paints himself as the latter. But when I assert the generic existence of preferences over beliefs, many economists challenge the whole category. How do I know preferences over beliefs exist? Some eminent economists imply that this is impossible to know because preferences are unobservable.

This is very similar to points that I have made from time to time on this blog. Like Caplan, I consider the fact that beliefs have a voluntary character, at least up to a certain point, to be virtually obvious. Likewise, Caplan points out that in the midst of a discussion an economist may take for granted the idea of the “emotional ideologue,” namely someone whose beliefs are motivated by emotions, but frequently he will not concede the point in generic terms. In a similar way, people in general constantly recognize the influence of motives on beliefs in particular cases, especially in regard to other people, but they frequently fight against the concept in general. C.S. Lewis is one example, although he does concede the point to some extent.

In the next post I will look at Caplan’s response to the economists, and at some point after that bring the discussion back to the question about the love of truth.
