RECOMPENSING JUSTICE.--Whoever has completely comprehended the doctrine of absolute irresponsibility can no longer include the so-called punishing and recompensing justice in the idea of justice, should this consist of giving to each man his due. For he who is punished does not deserve the punishment, he is only used as a means of henceforth warning away from certain actions; equally so, he who is rewarded does not merit this reward, he could not act otherwise than he did. Therefore the reward is meant only as an encouragement to him and others, to provide a motive for subsequent actions; words of praise are flung to the runners on the course, not to the one who has reached the goal. Neither punishment nor reward is anything that comes to one as _one's own;_ they are given from motives of usefulness, without one having a right to claim them. Hence we must say, "The wise man gives no reward because the deed has been well done," just as we have said, "The wise man does not punish because evil has been committed, but in order that evil shall not be committed." If punishment and reward no longer existed, then the strongest motives which deter men from certain actions and impel them to certain other actions, would also no longer exist; the needs of mankind require their continuance; and inasmuch as punishment and reward, blame and praise, work most sensibly on vanity, the same need requires the continuance of vanity. 106. AT THE WATERFALL.--In looking at a water-fall we imagine that there is freedom of will and fancy in the countless turnings, twistings, and breakings of the waves; but everything is compulsory, every movement can be mathematically calculated. So it is also with human actions; one would have to be able to calculate every single action beforehand if one were all-knowing; equally so all progress of knowledge, every error, all malice. The one who acts certainly labours under the illusion of voluntariness; if the world's wheel were to stand still for a moment and an all-knowing, calculating reason were there to make use of this pause, it could foretell the future of every creature to the remotest times, and mark out every track upon which that wheel would continue to roll. The delusion of the acting agent about himself, the supposition of a free will, belongs to this mechanism which still remains to be calculated. 107.
