Exactly.

Here an interesting quote from Alan Kay:

"The best teacher I had in graduate school spent the whole semester destroying any beliefs we had about computing. He was a real iconoclast. He happened to be a genius, so we took it. At the end of the course, we were free because we didn’t believe in anything. We had to learn everything, but then he destroyed it. He wanted us to understand what had been done, but he didn’t want us to believe in it."

Huh? That's kind of an unfair criticism. The word "believe" is more or less an explicit expression from the author that the article is, well, his belief. As a programmer, I like explicit declaration when reading someone else's "code".

The fault is more with you, for automatically associating the phrase "I believe" with implicit brainwashing.

You're badly misinterpreting it then; normally when people put forward something as a truth, they do so categorically. Instead they put the "believe" qualifier in. So they're not presenting it as a truth, but saying "I believe this, for the following reasons; you may agree with my reasoning."
