There is another question however: Are these general determinations absolutely true? And whence come they not alone into my consciousness, into my mind and understanding, but into the things themselves? Space, cause, effect, etc., are categories. How do these categories come into the particular? How does universal space arrive at determining itself? This point of view, the question whether these determinations of the infinite, of substance, etc., are in and for themselves true, is quite lost sight of. Plato investigated the infinite and the finite, Being and the determinate, etc., and pronounced that neither of these opposites is of itself true; they are so only as together constituting an identity, wherever the truth of this content may come from. But here the truth as it is in and for itself is entirely set aside and the nature of the content itself is made the main point. It does not matter whether the understanding or experience is its source, for the question is whether this content is in itself true. With Locke, the truth merely signifies the harmony of our conceptions with things; here relation is alone in question, whether the content is an objective thing or a content of the ordinary conception. But it is quite another matter to investigate the content itself, and to ask, “Is this which is within us true?” We must not dispute about the sources, for the Whence, the only important point to Locke, does not exhaust the whole question. The interest of the content in and for itself wholly disappears when that position is taken up, and thereby the whole of what is aimed at by Philosophy is given up. On the other hand, when thought is from the beginning concrete, when thought and the universal are synonymous with what is set before us, the question of the relation of the two which have been separated by thought is destitute of interest and incomprehensible. How does thought overcome the difficulties which itself has begotten? Here with Locke none at all have been begotten and awakened. Before the need for reconciliation can be satisfied, the pain of disunion must be excited.
