question whether we may properly abstract this hitherto invariable factor of a belief, and still call that belief by the same name. Or, to put the matter in another light, as cosmists maintain that Theism, in all the phases of its development, has been the product of a probably erroneous theory of personal agency in nature, when this theory is expressly discarded--as it is by the doctrine of the Unknowable--is it philosophically legitimate for cosmists to render their theory of things in terms which belong to the totally different theory which they discard? No doubt it is true that the progressive refinement of Theism has throughout consisted in a progressive discarding of anthropomorphic qualities; but this fact does not touch the consideration that, when we proceed to strip off the last remnants of these qualities, we are committing an act which differs _toto coelo_ from all the previous acts which are cited as precedents; for by this terminal act we are not, as heretofore, _refining_ the theory of Theism--we are completely _transforming_ it by removing an element which, both genetically and historically, would seem to constitute the very essence of Theism. Or the case may be presented in yet another light. The only use of terms, whether in daily talk or in philosophical disquisition, is that of designating certain things or attributes to which by general custom we agree to affix them; so that if anyone applies a term to some thing or attribute which general custom does not warrant him in so applying, he is merely laying himself open to the charge of abusing that term. Now apply these elementary principles to the case before us. We have but to think of the disgust with which the vast majority of living persons would regard the sense in which Mr. Fiske uses the term "Theism," to perceive how intimate is the association of that term with the idea of a Personal God. Such persons will feel strongly that, by this final act of purification, Mr. Fiske has simply purified the Deity altogether out of existence. And I scarcely think it is here competent to reply that all previous acts of purification were at first similarly regarded as destructive, because it is evident that none of these previous acts affected, as this one does, the central core of Theism. And, lastly, if it should be still further objected, that by declaring the theory of Personal Agency the central core of Theism, I am begging the question as to the appropriateness of Mr. Fiske's use of the word "Theism,"--seeing he appears to regard the essential meaning of this word to be that of a postulation of merely Causal Agency,--I answer, More of this anon; but meanwhile let it be observed that any charge of question-begging lies rather at the door of Mr. Fiske, in that he assumes, without any expressed justification, that the essence of Theism _does_ consist in such a postulation and in nothing more. And as he unquestionably has against him the present world of theists no less than
