and it possesses a very partial reality.[1] Nor are the imperceptibles of physics in any better case. Apart from the plain contradictions which prove them to be barely phenomenal, their nature clearly exists but in relation to thought. For, not being perceived by any finite, they are not, as such, perceived at all; and what reality they possess is not sensible, but merely abstract.
Our conclusion then, so far, will be this. Nature may extend beyond the region actually perceived by the finite, but certainly not beyond the limits of finite thought. In the Absolute possibly there is a margin not contained in finite experiences (Chapter xxvii.), but this possible margin cannot properly be taken as physical. For, included in Nature, it would be qualified by a relation to finite mind. But the existence of Nature, as mere thought, at once leads to a difficulty. For a physical world, to be real, must clearly be sensible. And to exist otherwise than for sense is but to exist hypothetically. If so, Nature, at least in part, is not actually Nature, but merely is what becomes so under certain conditions. It seems another fact, a something else, which indeed we think of, but which, merely in itself and merely as we think of it, is not physical reality. Thus, on our view, Nature to this extent seems not to be fact; and we shall have been driven, in the end, to deny part of its physical existence.
This conclusion urged against us, I admit, is in one sense inevitable. The Nature that is thought of, and that we assume not to be perceived by any mind, is, in the strict sense, not Nature.[2] Yet such a result, rightly interpreted, need cause us no trouble. We shall understand it better when we have discussed the meaning of conditional existence (Chapter xxiv.); I will however attempt to deal
