of darkness, which can never lead to blessedness. Kant's doctrine of virtue, however, we do not find so pure; or rather the exposition remains far behind the spirit of it, and indeed falls into inconsistency. In his highest good, which he afterwards discussed, we find virtue united to happiness. The ought originally so unconditioned does yet afterwards postulate one condition, in order to escape from the inner contradiction with which it is affected and with which it cannot live. Happiness in the highest good is not indeed really meant to be the motive for virtue; yet there it is, like a secret article, the existence of which reduces all the rest to a mere sham contract. It is not really the reward of virtue, but yet it is a voluntary gift for which virtue, after work accomplished, stealthily opens the hand. One may convince oneself of this from the "Critique of Practical Reason" (p. 223-266 of the fourth, or p. 264-295 of Rosenkranz's, edition). The whole of Kant's moral theology has also the same tendency, and just on this account morality really destroys itself through moral theology. For I repeat that all virtue which in any way is practised for the sake of a reward is based upon a prudent, methodical, far-seeing egoism.
The content of the absolute ought, the fundamental principle of the practical reason, is the famous: "So act that the maxim of your will might always be also valid as the principle of a universal legislation." This principle presents to him who desires a rule for his own will the task of seeking such a rule for the wills of all. Then the question arises how such a rule is to be found. Clearly, in order to discover the rule of my conduct, I ought not to have regard to myself alone, but to the sum of all individuals. Then, instead of my own well-being, the well-being of all without distinction becomes my aim. Yet the aim still always remains well-being. I find, then, that all can be equally well off only if each limits his own egoism by that of others. From this it certainly follows that I must injure no one, because, since this principle is
