Kant: Kant's problem

Kant wonders whether or not Hume's problem is through nature.

1- Does Hume's problem generalize by means of cause and effect
Empiricists hold the knowledge of cause and effect is aposteriority.
Based on consumption For ex- if triangle A is larger than triangle B then Aposteriority would be B < A.
The assumption that A has three sides is Apriori.

2- If it does generalize that the knowledge is of nature... there should be 3 distinctions
(A) Apriori- it is a true independant of the observation/Apostiori
(B) Analytic- True by def. of Kant (yes, there are apriori synthetic statements)/Synthetic judgement
(C) Necessity- true in all possible worlds/ contingency
