Let's take the best computer programmer. Imagine he tries to write down all his important knowledge in a book. He writes down all statements where he believes that he can justify that they are true in a book.

Then he gives the book to a person who never programmed with equal IQ.

How much of the knowledge of the expert knowledge get's passed down through this process? I grant that some knowledge get's passed down, but I don't think that all knowledge does get passed down. The expert programmer has what's commonly called "unconscious competence".

Allen might call that kind of knowledge part of the best knowledge of our civilization. It's crucial knowledge for our technological progress.

But to get back to the main point, to accept that the contemplative, logocentric approach has flaws is not simply about focusing on it itself but on demonstrating alternatives.
