Book Description

In this thesis, I analyze the classical tripartite definition of knowledge. According to this definition there are three conditions for a knowledge claim to arise, namely, belief, truth and justification conditions. The main problem with this definition is even if these three conditions are satisfied one may not know a proposition p because of the fact that the justification of the proposition p may not be relevant in showing that p is true. Therefore, my primary purpose is to establish a strong conceptual connection between justification and truth conditions. To realize this, first, I defend a three-way interrelation between these three conditions. Second, I inquire as to which kind of justification should lead us to which kind of truth. To answer to this question, I postulate three kinds of realities, namely, Subjective Reality, Inter-Subjective Reality, and Allegedly Pure Reality. Furthermore, I re-define the justification condition in such way that there is a kind of 3whole justification4 and it requires both internal and external justification. According to this conception of reality and re-definition of justification there already exists a strong conceptual connection between internal justification and Subjective Reality which is completely subject-relative. And I defend the existence of such a connection also between the whole justification and Inter-Subjective Reality. Finally, I argue that no conception of justification can lead us to an Allegedly Pure Reality that the hardest version of skepticism claims to exist.
