Sure you could say that we all believe in something, since nothing is ever proven. But you know if I used that statement in the wrong thread, people would jump all over it.
What on earth are you talking about? Logic is based on some axiomatic assumptions (such as the law of non-contradiction) that one just has to accept. I believe that one can rationally intuit these assumptions. But I can't prove the validity of rational intuition.
This shows I'm not a thorough-going nihilist, but other than that I think I'm very nihilistic.
The idea is to keep the assumptions to a minimum.
Of course I have feelings, such as moral feelings--or at least I think that's what they are. What are they based on logically? Nothing at all. Nonetheless they sometimes determine my behavior.
Everybody believes in something--that's my view.
