Genesis tells the story of the Tower of Babel:
Now the whole earth had one language and the same words. And as they migrated from the east, they came upon a plain in the land of Shinar and settled there. And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. Then they said, “Come, let us build ourselves a city, and a tower with its top in the heavens, and let us make a name for ourselves; otherwise we shall be scattered abroad upon the face of the whole earth.” The Lord came down to see the city and the tower, which mortals had built. And the Lord said, “Look, they are one people, and they have all one language; and this is only the beginning of what they will do; nothing that they propose to do will now be impossible for them. Come, let us go down, and confuse their language there, so that they will not understand one another’s speech.” So the Lord scattered them abroad from there over the face of all the earth, and they left off building the city. Therefore it was called Babel, because there the Lord confused the language of all the earth; and from there the Lord scattered them abroad over the face of all the earth.
The account suggests that language is a cause of technology, as when the Lord says, “this is only the beginning of what they will do; nothing that they propose to do will now be impossible for them.”
But is possible to understand language here as a technology itself, one which gives rise to other technologies. It is a technology by which men communicate with each other. In the story, God weakens the technology, making it harder for people to communicate with one another, and therefore making it harder for them to accomplish other goals.
But language is not just a technology that exists for the sake of communication; it is also a technology that exists for the sake of thought. As I noted in the linked post, our ability to think depends to some extent on our possession of language.
All of this suggests that in principle, the idea of technological progress is something that could apply to language itself, and that such progress could correspondingly be a cause of progress in truth. The account in Genesis suggests some of the ways that this could happen; to the degree that people develop better means of understanding one another, whether we speak of people speaking different languages, or even people already speaking the same language, they will be better able to work together towards the goal of truth, and thus will be better able to attain that goal.
