But may Matter not be real apart from all its so-called qualities, these being allowed to be not wholly material, because real only within percipient spirit? May not this wholly material Matter be Something that, as it were, exists _behind_ the ideas, phenomena, or qualities that make their appearance to human beings? This question, Berkeley would say, is a meaningless and wholly unpractical one. Material substance that makes and can make no real appearance—unphenomenal or unideal—stripped of all its qualities—is only “another name for abstract Being,” and “the abstract idea of Being appeareth to me the most incomprehensible of all other. When I consider the two parts or branches which make up the words _material substance_, I am convinced there is no distinct meaning annexed to them” (sect. 17). Neither Sense nor Reason inform us of the existence of real material substances that exist _abstractly_, or out of all relation to the secondary and primary qualities of which we are percipient when we exercise our senses. By our senses we cannot perceive more than ideas or phenomena, aggregated as individual things that are presented to us: we cannot perceive substances that make no appearance in sense. Then as for reason, unrealised substances, abstracted from living Spirit, human or divine, being altogether meaningless, can in no way explain the concrete realisations of human experience. In short, if there are wholly unphenomenal material substances, it is impossible that we should ever discover them, or have any concern with them, speculative or practical; and if there are not, we should have the same reason to assert that there are which we have now (sect. 20). It is impossible to put any meaning into wholly abstract reality. “To me the words mean either a direct contradiction, or nothing at all” (sect. 24). ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐
