As the will itself is not phenomenon, not representation or object, but thing-in-itself, it is also not subordinate to the principle of sufficient reason, the form of all object. Thus it is not determined as consequent by a reason or concept or ground, and so it knows no necessity; in other words, it is free. The concept of freedom is therefore really a negative one, since its content is merely the denial of necessity, in other words, the denial of the relation of consequent to its ground according to the principle of sufficient reason . . . Everything as phenomenon, as object, is absolutely necessary; in itself it is will, and this is perfectly free to all eternity.
