Distinguished Ways To Achieve Knowledge: A Priori and A Posteriori.

From a knowledge perspective, the main focus of philosophers is to know the knowledge of propositions or whether things exist (Vaughn, 254). Philosophers believe that propositional knowledge has three conditions necessary to understand the proposition. In other words, because we believe in something, that will not happen. Now, to gain knowledge, our beliefs must be true, and we must have a good reason to believe that they are true.

Since the era of Emmanuel Kant, transcendental knowledge in Western philosophy was independent from knowledge of all specific experiences, not knowledge after experience derived from experience. Latin phrases A priori ("before") and after ("after") are used in philosophy to distinguish cause and effect arguments. The first appearance of these phrases took place at the work of a logical scientist at Albert in Saxony of the 14th century. Here, the a priori discussion is called "from reason to result", the latter argument is called "result to cause". Later philosophers gave similar definitions including G. W. Leibniz.

The two terms a priori and posterior are used in philosophy to distinguish between two different types of knowledge. Transcendental knowledge has nothing to do with experience For example, all bachelor's degrees are unmarried men. You only understand the phrase definition, so you can see that this is a priori knowledge. From now on we can conclude that all unmarried men are single and that married men can not become single. According to Kant, all previous knowledge is analytic, which means that previous knowledge is correct only by its meaning.

Kant suggests two important differences: between a priori knowledge and posterior knowledge, and between analysis and comprehensive judgment. Transcendental knowledge is the necessity and universal knowledge that is independent of experience, such as our mathematical knowledge. In analysis analysis, the concept in the predicate is included in the concept in the subject, for example, "In a judgment" the singles are unmarried. "(In this case, the predicate refers to one of the mentioned contents) For example, In a comprehensive judgment, since the predicate concept contains information not included in the subjective concept, comprehensive judgment is useful rather than just defining. Usually we associate post hoc knowledge with comprehensive judgment, prior knowledge and analytical judgment.
