ABSTRACT
Thus we are back with our old hypothesis: the only remaining possibility is what seemed most likely in the first place. The principles of ethical knowledge must be either experiences or analytic a priori cognitions. No other kinds of principles exist in ethics or in any other body of knowledge. But for precisely that reason the possibilities are boundless, and we still lack any indication that some particular concept or fact is the starting-point of ethical proofs. Hence we must start from the very beginning in a different manner and determine how we are to find the point at which ethical investigations are to begin.
