That which is generally received as positive, which we call the real, and the negation of which the concept nothing in its most general significance expresses, is just the world as idea, which I have shown to be the objectivity and mirror of the will. Moreover, we ourselves are just this will and this world, and to them belongs the idea in general, as one aspect of them. The form of the idea is space and time, therefore for this point of view all that is real must be in some place and at some time. Denial, abolition, conversion of the will, is also the abolition and the vanishing of the world, its mirror. If we no longer perceive it in this mirror, we ask in vain where it has gone, and then, because it has no longer any where and when, complain that it has vanished into nothing.
