“The free being with absolute freedom proposes to itself certain ends. It wills because it wills, and the willing of an object is itself the last ground of such willing. Thus we have previously determined a free being, and any other determination would destroy the conception of an Ego, or of a free being. Now, if it could be so arranged that the willing of an unlawful end would necessarily — in virtue of an always effective law — result in the very reverse of that end, then the unlawful will would always ANNIHILATE ITSELF. A person could not will that end for the very reason because he did will it; his unlawful will would become the ground of its own annihilation, as the will is indeed always its own last ground.”
