 suppose that mere thought without facts could either be real, or could reach to truth, is evidently absurd. The series of events is, without doubt, necessary for our knowledge, since this series supplies the one source of all ideal content. We may say, roughly and with sufficient accuracy, that there is nothing in thought, whether it be matter or relations, except that which is derived from perception. And, in the second place, it is only by starting from the presented basis that we construct our system of phenomena in space and time. We certainly perceived (Chapter xviii.) that any such constructed unity was but relative, imperfect, and partial. But, none the less, a building up of the sense-world from the ground of actual presentation is a condition of all our knowledge. It is not true that everything, even if temporal, has a place in our one “real” order of space or time. But, indirectly or directly, every known element must be connected with its sequence of events, and, at least in some sense, must show itself even there. The test of truth after all, we may say, lies in presented fact.

We should here try to avoid a serious mistake. Without existence we have perceived that thought is incomplete; but this does not mean that, without existence, mere thought in itself is complete fully, and that existence to this super-adds an alien but necessary completion. For we have found in principle that, if anything were perfect, it would not gain by an addition made from the outside. And, here in particular, thought’s first object, in its pursuit of actual fact, is precisely the enlarging and making harmonious of its own ideal content. And the reason for this, as soon as we consider it, is obvious. The dollar, merely thought of or imagined, is comparatively abstract and void of properties. But the dollar, verified in space, has got its place
