"I am not now considering," says Mr. Mill, "what it is that, in our author's opinion, we are bound to believe concerning the unknowable." Why, this was the very thing he ought to have considered, before pronouncing the position to be untenable, or to be irreconcilable with something else. Meanwhile, it is instructive to observe that Mr. Mill himself believes, or requires his readers to believe, something concerning the unknown. He does not know, or at any rate he does not tell his readers, what Hamilton requires them to believe concerning the unknowable; but he himself believes, and requires them to believe, that this unknown something is incompatible with the doctrine that knowledge is relative. We cannot regard this as a very satisfactory mode of refuting Hamilton's thesis.[AY] [AY] In a subsequent chapter (p. 120), Mr. Mill endeavours to overthrow this distinction between Knowledge and Belief, by means of Hamilton's own theory of Consciousness. Hamilton maintains that we cannot be conscious of a mental operation without being conscious of its object. On this Mr. Mill retorts that if, as Hamilton admits, we are conscious of a belief in the Infinite and the Absolute, we must be conscious of the Infinite and the Absolute themselves; and such consciousness is Knowledge. The fallacy of this retort is transparent. The immediate object of Belief is a _proposition_ which I hold to be true, not a _thing_ apprehended in an act of conception. I believe in an infinite God; _i.e._, I believe _that_ God is infinite: I believe that the attributes which I ascribe to God exist in Him in an infinite degree. Now, to believe this proposition, I must, of course, be conscious of its meaning; but I am not therefore conscious of the Infinite God as an object of conception; for this would require further an apprehension of the manner in which these infinite attributes coexist so as to form one object. The whole argument of this eighth chapter is confused, owing to Mr. Mill not having distinguished between those passages in which Sir W. Hamilton is merely using an _argumentum ad hominem_ in relation to Reid, and those in which he is reasoning from general principles.
