Kant

Kant as what he calls a general problem How is cognition from pure Reason possible? He said that it is being entirely founded on the principle of contradiction. It is the judgment that we gathered from experience and no special expiation. and that they must depend on other principles than that of contrasting.
So Kant is saying what Hume and Locke said that are reasoning for things come from are experience. That because of the reaction or effect that we had in the past is going to effect what we do in the future.
For if A equals B and B is not something that you want A to equal then you many choose not to do A. But if A equals be and B is the effect you want then you will keep doing A.
Kant thinks the same as all the others we read he just uses different words to describe what he is saying.
