These components together, arguably, give us the three necessary and sufficient ingredients for knowledge. The theory can be presented in the following way:

However, some, such as Gettier, have contested that such a theory is sufficient for knowledge. Others reject the notion of knowledge altogether. Whilst I agree that these three conditions are wholly and inarguably necessary for knowledge I agree with others in that JTB alone is not sufficient for knowledge.

Justified True Belief was a concept intended to be the equivalent of knowledge. Plato described the truth condition as necessary for knowledge, claiming you can’t know something that is false. Most epistemologists agreed that it was a reasonable condition, that what is false cannot be known (Ichikawa, J.
