Thus then criticisms like this of Mr. Martineau, often recurring in one shape or other, and now again made by Mr. Harrison, do not show the invalidity of my argument, but once more show the imbecility of human intelligence when brought to bear on the ultimate question. Phenomenon without noumenon is unthinkable; and yet noumenon cannot be thought of in the true sense of thinking. We are at once obliged to be conscious of a reality behind appearance, and yet can neither bring this consciousness of reality into any shape, nor can bring into any shape, its connexion with appearance. The forms of our thought, moulded on experiences of phenomena, as well as the connotations of our words formed to express the relations of phenomena, involve us in contradictions when we try to think of that which is beyond phenomena; and yet the existence of that which is beyond phenomena is a necessary datum alike of our thoughts and our words. We have no choice but to accept a formless consciousness of the inscrutable. * * * * * I cannot treat with fulness the many remaining issues. To Mr. Harrison’s statement that it was uncandid in me to implicate him with the absurdities of the Comtean belief and ritual, notwithstanding his public utterances, I reply that whereas ten years ago I was led to think he gave but a qualified adhesion to Comte’s religious doctrine, such public utterances of his as I have read of late years, fervid in their eloquence, persuaded me that he had become a much warmer adherent. On his summary mode of dealing with my criticism of the Comtean creed some comment is called for. He remarks that there are “good reasons for declining to discuss with Mr. Spencer the writings of Comte;” and names, as the first, “that he knows [I know] nothing whatever about them” (p. 365). Now as Mr. Harrison is fully aware that thirty years ago I reviewed the English version of those parts of the Positive Philosophy which treat of Mathematics, Astronomy and Physics; and as he has referred to the pamphlet in which, ten years later, I quoted a number of passages from the original to signalize my grounds of dissent from Comte’s system; I am somewhat surprised by this statement, and by the still more emphatic statement that to me “the writings of Comte are, if not the Absolute Unknowable, at any rate the Absolute Unknown” (p. 365). Doubtless these assertions are effective; but like many effective assertions they do not sufficiently recognize the facts. The remaining statements in this division of Mr. Harrison’s argument, I pass over: not because answers equally adequate with those I have thus far given do not exist, but because I cannot give them without entering upon personal questions which I prefer to avoid.
