Plato's three (3) criteria for a claim to be considered Knowledge: 1) Justification, 2) Truth, and 3) Belief?

Question

I know little about the explanation for each criterion. Like for TRUTH, it can either be Fact (validated by our sensible experience), or Reason (reason alone). For BELIEF, it should be accepted by a "community" of believers. And as for JUSTIFICATION, well, I forgot how our professor elaborated on that in relation to being a criterion of Knowledge.

Can anyone please help me? Thanks!

Answer 1

heory of justification is a part of epistemology that attempts to understand the justification of propositions and beliefs. Epistemologists are concerned with various epistemic features of belief, which include the ideas of justification, warrant, rationality, and probability. Of these four terms, the term that has been most widely used and discussed in the past twenty years is "justification". Loosely speaking, justification is the reason why someone (properly) holds the belief, the explanation as to why the belief is a true one, or an account of how one knows what one knows.

Belief is the psychological state in which an individual holds a proposition or premise to be true.

The meaning of the word truth extends from honesty, good faith, and sincerity in general, to agreement with fact or reality in particular. The term has no single definition about which a majority of professional philosophers and scholars agree. Various theories of truth continue to be debated. There are differing claims on such questions as what constitutes truth; how to define and identify truth; the roles that revealed and acquired knowledge play; and whether truth is subjective, relative, objective, or absolute. This article introduces the various perspectives and claims, both today and throughout history.

Answer 2

Justification is the idea of reasons for belief, reasons that entitle you to a belief. It is not a good reason for believing something that I wish were true; reasons have to consist of other things I take to be true. Beliefs must be based on evidence if they are to count as knowledge.
