I am guessing this is the empirist VS Rationalist discusion?
I love epistemology :D
Anyway one of Sokrates most famus missquotes (not mentioned once in Platos works) explains it well:
"I know, I know nothing"
but this would be knowlage, in other words, if no real knowlage is posible it would be imposible to know.
if a yes we would have to know for sure to say it and we cant know anything for sure, so no. b if no the world wouldnt exist and thus we couldnt state it doesnt exist so no. c is correct. d is socrates old classical answer but modern school says its wrong because we can have true beliefs about something and they consider it somewhat knowledge. e no because definition of existence means absolute, universal, independent (not dependent on your mind) f. same problem g. same problem as "a" h. same problem as "e" i is saying the same thing as a, because if it were not, it would run into the same problem as h, not including universally, absolutely.
C (according to hyper-modern school), d according to classical school. But modern era we are in so C.
thanks for laying it out and being clearApotek You are welcome.
I hate to admit it,but while I would choose the safety of c) or d) to pass an exam,I am secretly an a) guy.In other words,I believe that chess does exist..
