Document Summary
Knowledge versus mere justified belief knowledge implies truth justified belief does not imply truth. Recall what makes a good inductive argument: good sample size: a big sample size gives more reason, good sample distribution (sample must be representative of total, these requirements assume there are better or worse evidential relations. Obviously (gen) and (pred) are not deductively valid argument forms. But it seems intuitively obvious that the premises give us a good reason to believe the conclusion. Hume argues that this intuition is unsupportable and wrong. Hume"s version: he believed that all inductive arguments involved one crucial assumption: the.
