yeh, Im talking historical facts arent very liable, religious facts arnt very reliable, theory and scientific.
for instance history is written by the victors, to me thats not reliable fact.
Everything is somewhat onesided. Fact comes with trust. I dont trust.
Philosophical points of views on anything is a good thing to take a personal outlook on.
Existentialism looks alot at emotion,actions,and source of knowledge. Im not saying that Existentialism is 100% correct, I havent learnt enough about it to make a valid expression on it, but I will in no way shut out anything I read or learn. It is very much valid source of theorys, point of views, statment and facts. Which relates to your statment "But speculating on something, and believing something are two different things" I open my mind to all ways of thinking and creating a understaning of any situation emotion and thought, So far Existentialism is preaching that.
That not one way of gathering information is correct, and not one source will be correct.
All though I feel Existentialism to a certain extent is outdating itself. but its definitly not be shut out.
But i am yet to gather a full understanding of it.

I said somewhat a contridiction, not a entire contridictory statment.
