· Immanuel Kant ·

              This philosopher used premises to justify something, to prove it is true. There are four types of judgments; the analytic proposal, which stated that something said about a concept is implicit because what was said is included in the definition of the concept, such as bachelors are unmarried; the synthetic proposal is when saying something about a thing that is not included in the definition of that thing, for example: all bachelors are unhappy; A priori is a proposition that doesn't require us to experience it in order to know that, we don't need to be bachelors to know they are unmarried; and the last one is A posteriori, this one does require experience. 

                Kant affirms that we can combine those judgments, but in order to be true, we must make the right combinations; an analytic proposal with A priori, it does make sense, because we do not need to experience being a dog to know them; a synthetic proposal with A priori, those are things you can deduce, if you see a girl with her arm plastered and you say she broke her arm, a broken arm is not part of the definition of "girl", but it may be true; a synthetic proposal and a A posteriori, when what is said is not part of the definition and we must experience it in order to know it, such as getting to know a bachelor who is unhappy. 

Immanuel said that we could never achieve the whole knowledge of a thing, because we will never know its real purpose neither all their characteristics. After using the reason and experience, we get to a final interpretation, but we cannot know the real essence of the thing, which is called noumena.
