Justification is one of the three traditional conditions for knowledge. Plato in the Theatetus defined knowledge as justified true belief. Unfortunately, the notion of justification of a belief by providing reasons is vague. It involves circularity or an infinite regress of reasons. What reasons can be given that themselves do not have just reasons? In view of (i) and (ii) what value is there in a "justification" that is fallible, or worse false?
