360 THE WORLD AS WILL. bk. iv.
present; the past and the future contain only conceptions and fancies, therefore the present is the essential form of the phenomenon of the will, and inseparable from it. The present alone is that which always exists and remains immovable. That which, empirically apprehended, is the most transitory of all, presents itself to the metaphysical vision, which sees beyond the forms of empirical perception, as that which alone endures, the nunc stans of the schoolmen. The source and the supporter of its content is the will to live or the thing-in-itself, — which we are. That which constantly becomes and passes away, in that it has either already been or is still to be, belongs to the phenomenon as such on account of its forms, which make coming into being and passing away possible. Accordingly, we must think: — Quid fuit? — Quod est. Quid erit? — Quod fuit; and take it in the strict meaning of the words; thus understand not simile but idem. For life is certain to the will, and the present is certain to life. Thus it is that every one can say, "I am once for all lord of the present, and through all eternity it will accompany me as my shadow: therefore I do not wonder where it has come from, and how it happens that it is exactly now." We might compare time to a constantly revolving sphere; the half that was always sinking would be the past, that which was always rising would be the future; but the indivisible point at the top, where the tangent touches, would be the extensionless present. As the tangent does not revolve with the sphere, neither does the present, the point of contact of the object, the form of which is time, with the subject, which has no form, because it does not belong to the knowable, but is the condition of all that is knowable. Or, time is like an unceasing stream, and the present a rock on which the stream breaks itself, but does not carry away with it. The will, as thing-in-itself, is just as little subordinate to the principle of sufficient reason
