I myself ultimately believe that true knowledge is unobtainable, logic itself becomes a logical contradiction if you go back far enough into a system of beliefs, and is no more certain than any other reason people have for believing the things they do. the only way I could ever be totally unbiased, and not relying on my own fundamentally uncertain beliefs about the nature of logic and its applications to the properties of truth, would be to stop thinking altogether. I can't view reality at all without that fundamental filter of bias I require to function. In that regard, logic itself can be considered a bias, so when it comes to trying to be objective, through the attempt alone we show bias. I accept logic as the only reliable tool for understanding reality, but in doing so, must allow myself to accept a fundamental belief without any true knowledge. If however, I did not accept logic or some alternative fundamental belief as such, I couldn't think about reality in the first place. Logic however has the ability to identify this flaw within itself, so through logic, at least one can become aware of the paradox. I consider that an accomplishment in itself, which makes me feel as though I'm on the right track with my fundamental beliefs. Of course that too is unprovable.
