§ 55. That the will as such is _free_, follows from the fact that, according to our view, it is the thing-in-itself, the content of all phenomena. The phenomena, on the other hand, we recognise as absolutely subordinate to the principle of sufficient reason in its four forms. And since we know that necessity is throughout identical with following from given grounds, and that these are convertible conceptions, all that belongs to the phenomenon, _i.e._, all that is object for the knowing subject as individual, is in one aspect reason, and in another aspect consequent; and in this last capacity is determined with absolute necessity, and can, therefore, in no respect be other than it is. The whole content of Nature, the collective sum of its phenomena, is thus throughout necessary, and the necessity of every part, of every phenomenon, of every event, can always be proved, because it must be possible to find the reason from which it follows as a consequent. This admits of no exception: it follows from the unrestricted validity of the principle of sufficient reason. In another aspect, however, the same world is for us, in all its phenomena, objectivity of will. And the will, since it is not phenomenon, is not idea or object, but thing-in-itself, and is not subordinate to the principle of sufficient reason, the form of all object; thus is not determined as a consequent through any reason, knows no necessity, _i.e._, is _free_. The concept of freedom is thus properly a negative concept, for its content is merely the denial of necessity, _i.e._, the relation of consequent to its reason, according to the principle of sufficient reason. Now here lies before us in its most distinct form the solution of that great contradiction, the union of freedom with necessity, which has so often been discussed in recent times, yet, so far as I know, never clearly and adequately. Everything is as phenomenon, as object, absolutely necessary: _in itself_ it is will, which is perfectly free to all eternity. The phenomenon, the object, is necessarily and unalterably determined in that chain of causes and effects which admits of no interruption. But the existence in general of this object, and its specific nature, _i.e._, the Idea which reveals itself in it, or, in other words, its character, is a direct manifestation of will. Thus, in conformity with the freedom of this will, the object might not be at all, or it might be originally and essentially something quite different from what it is, in which case, however, the whole chain of which it is a link, and which is itself a manifestation of the same will, would be quite different also. But once there and existing, it has entered the chain of causes and effects, is always necessarily determined in it, and can, therefore, neither become something else, _i.e._, change itself, nor yet escape from the chain, _i.e._, vanish. Man, like every other part of Nature, is objectivity of the will; therefore all that has been said
