Abstract

In “Is Justified True Belief, Knowledge?” Gettier shows us two counter examples of analyzing Knowledge, as “Justified True Belief” or “JTB”. Lots of scholars have reconstructed similar counter examples to JTB but we can see they follow a similar algorithm. Other scholars have tried to re-analyze knowledge by adding a fourth element to JTB and reformulating knowledge in a “JTB+X” formula and some replaced justification with another alternative component (Y) and proposed a “YTB” analysis of knowledge. In this article I first overview Gettier’s problem and I show that we can construct a similar Gettier problem for each “JTB+X” or “YTB” formula. After that, I will focus on re-analyzing knowledge with a phenomenological attitude that can avoid Gettier’s problem.
