Categorial Imperative

While reading the piece I noticed a point that I did not get the first time around which was the idea of categorial imperative. The idea we have seen before is hypothetical imperative which is showing about how to get to end result that would make the person most happy. Categorical imperative is the idea of  actually choosing the right action to get to that end. Its a bit of an inception-esque idea in a  decision within a decision within a decision but it is trying to find the moral logic within the decisions of the end results that make us happy. Because we cannot be sure that people make certain decisions of pure interests solely we have to to assume that the idea of categorical imperative is a derivation of the piori. Therefore people do things even if it be for circumstantial interest because otherwise the logic to reasoning could not actually go forward. Kant brings up very good examples about debts and and suicide in that they represent categorial imperative. One being that debts are payed not only because of interest but also because money needs to circulate for life to continue, and suicide isn't performed because people believe life is precious and needs to be kept sacred, but also because if everyone killed themselves life could not move on so we could not procreate.
