"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… 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."
