In the interest of brevity and encouraging you to read a long reply...

You are far more versed in philosophy than I am, yet my limited knowledge I agree with you. I see this facade of having a philosophy in religion as well and I feel that the problem, as I've said, is rooted in the fundamental conflict within the conditioned mind. And I don't think it's a matter of insincerity, but rather ignorance. I have spoken to people on the right of the spectrum and they are sincere in their ignorance. The same holds true for those on the left. Religious people are the same. This is because life presents the entire range from good to bad and the individual must ignore and reject (albeit unconsciously) some of what he is so that he can face the world without shame and other emotions. It is impossible for the internal conflict of people not to present itself in their institutions and so-called philosophies.

On this idea of "philosophical knowledge..." This phrase doesn't sit right, because knowledge is information that is almost always secondhand then adopted and internalized. Compare this to direct observation without the interference of the conflicted mind.

What does it really mean to respect knowledge or search for it? It doesn't seem to me that this search nor knowledge itself is without bias and that people gravitate toward proving themselves right and righteous rather than trying to get at the truth.
