“ When we ask, however, how this non-physical reality of which the physical order is the phenomenal manifestation to our senses, is to be thought of, we find ourselves at once plunged into the same difficulties which we have already met, in a more general form, in discussing the concept of Substance. Popular thought, and science so far as it is content to accept the notions of popular thought without criticism, have commonly fallen back on the idea of the non-phenomenal ground of the physical order as an unperceived “substratum.” ”

“ Substance and Quality. The identification of the substance of things with their primary qualities, though useful in physical science, is metaphysically unjustifiable. § 5. Substance as an “unknowable substratum of qualities” adds nothing to our understanding of their connection. § 6. The thing cannot be a mere collection of qualities without internal unity. § 7. The conception of a thing as the law or mode of relation of its states useful but metaphysically unsatisfactory. ”

“ But the inconsistencies we have already found inherent in such a conception of Substance as is here presupposed, so inevitably make themselves felt upon any serious examination, that the doctrine regularly appears in the history of thought as a mere temporary halting-place in the advance to the more radical notion of matter as the entirely unknown non-phenomenal substratum of the sensible properties of bodies. ”
