So there was a guy in academic epistemology who allegedly turned the whole field upside down in the 1900's, by proving that having Justified True Belief in an idea is insufficient for having knowledge of said idea. Read up if you want: https://en.wikipedia.org/wiki/Gettier_problem https://books.google.se/books?hl=sv&lr=&id=Gp9Umi2VEh8C&oi=fnd&pg=PA175&dq=Is+Justified+True+Belief+Knowledge%3F&ots=OGD1Xq6SY1&sig=qfXz6_nL9-_008Z6WmjehU7cKFU&redir_esc=y#v=onepage&q=Is Justified True Belief Knowledge%3F&f=false How I would sum it up: Gettier provided some examples where an individual S deduces an idea Q which happens to be True, but the reasoning is based on a false premise P, which nonetheless is rationally Justified. Thus the individual does not know that the idea Q is true, and does not have knowledge of Q, but still Believes the idea. Thus it is claimed that S has Justified True Belief in something which is not knowledge, and JTB is an insufficient condition for knowledge. The whole thing bothers me and I'm trying to figure out why. Is this an attempt at proving that knowledge is impossible, or can it actually make rational sense within objectivist epistemology? What to make of it all?
