In this paper, I will discuss the truth-belief-justification conceptual analysis of knowledge, which I will refer to as TBJ, Gettier cases, and an example that refutes TBJ. Conceptual analysis is an analysis of a proposition P with given premises to acquire knowledge of that P. The truth-belief-justification analysis of knowledge fails to provide sufficient conditions for someone to possess knowledge. For a condition to be necessary, it has to be satisfied to have knowledge of a proposition. If a condition is sufficient, then the person x will have some information to know something about proposition P. Jointly sufficient conditions are conditions that all need to be satisfied together to have knowledge about some P. They are necessary and supposedly jointly sufficient, but Gettier cases prove that extra conditions on top of TBJ are required to be jointly sufficient. The TBJ analysis identifies three conditions that are necessary and supposedly jointly sufficient for some person x to know some proposition P. Truth indicates that the proposition P has to be true. The truth needs to correspond to some true fact that relates to the world, such as that the Earth is round. It is necessary because a proposition P can only be deduced by factual evidence shown to x. However, truth by itself is not sufficient because truth itself is just a random fact. In addition, the person, x, needs to hold some sort of belief in their proposition P. If you do not believe in a proposition P, then it cannot be known, since you will not have any grounds on which to base your knowledge of that P. It is a necessary condition since “you can only know what you believe”. However, it is not a sufficient condition by itself because a belief is just x’s opinion of a subject. Finally, the person, x’s belief has to be accompanied by observations from their senses, prior knowledge, or deductive reasoning, which in effect, explains what the justification is. This may come from what people may see with their eyes, or forming a conclusion from previously assumed premises. Justification is a necessary condition because the allegedly known beliefs have to be adequately justified. Fallibility of justification is assumed since no justification can
