for they make a mere empty show of knowledge which at once vanishes when science comes on the scene.
But science, in the very fact that it comes on the scene, is itself a phenomenon; its “coming on the scene” is not yet itself carried out in all the length and breadth of its truth. In this regard, it is a matter of indifference whether we consider that it (science) is the phenomenon because it makes its appearance alongside another kind of knowledge, or call that other untrue knowledge its process of appearing. Science, however, must liberate itself from this phenomenality, and it can only do so by turning against it. For science cannot simply reject a form of knowledge which is not true, and treat this as a common view of things, and then assure us that itself is an entirely different kind of knowledge, and holds the other to be of no account at all; nor can it appeal to the fact that in this other there are presages of a better. By giving that assurance it would declare its force and value to lie in its bare existence; but the untrue knowledge appeals likewise to the fact that it is, and assures us that to it science is nothing. One barren assurance, however, is of just as much value as another. Still less can science appeal to the presages of a better, which are to be found present in untrue knowledge and are there pointing the way towards science; for it would, on the one hand, be appealing again in the same way to a merely existent fact; and, on the other, it would be appealing to itself, to the way in which it exists in untrue knowledge, i.e. to a bad form of its own existence, to its appearance, rather than to its real and true nature (an und für sich). For this
