Freedom's possibility is not the ability to choose the good or the evil. The possibility is to be able. In a logical system, it is convenient to say that possibility passes over into actuality. However, in actuality it is not so convenient, and an intermediate term is required. The intermediate term is anxiety, but it no more explains the qualitative leap than it can justify it ethically. Anxiety is neither a category of necessity nor a category of freedom; it is entangled freedom, where freedom is not free in itself but entangled, not by necessity, but in itself.
