What leads to determinism is the fact that struggle is made necessary continuously. In a particular case the decision may follow quite ethically, and man may decide himself for the Good; yet the decision is not lasting, he must struggle anew. There is freedom, one might say, only for the moment.

And that lies in the concept of a freedom. For what kind of a freedom would it be which I, through a good act from some earlier time, had brought forth, caused, for all time? It is the very pride of man that he can be free anew at every moment. So for the future, as for the past, there is no freedom; man has no power over them.
