No one will suspect us of any prejudice against Professor Huxley. We have often praised his vigorous writings, and his admirable service to Freethought. We recognise him as a powerful fighter in the great battle between Reason and Faith. He is a born controversialist, he revels in the vivisection of a theological opponent, and it is easy to understand how the more placid Darwin could cry to him admiringly, "What a man you are!" But for some reason or other it seems the fate of Professor Huxley, as it is the fate of Herbert Spencer, to be made use of by the enemies of Freethought; and it must be admitted that, to a certain extent, he gratuitously plays into their hands. Mr. Herbert Spencer has been a perfect god-send to the Christians with his "Unknowable"--the creation of which was the worst day's work he ever accomplished. It is only a big word, printed with a capital letter, to express the objective side of the relativity of human, knowledge. It connotes all that we do not know. It is a mere confession of ignorance; it is hollowness, emptiness, a vacuum, a nothing. And this nothing, which Mr. Spencer adorns with endless quasi-scientific rhetoric, is used as a buttress to prop up tottering Churches. Professor Huxley has been nearly as serviceable to the Churches with his "Agnosticism," which belongs to the same category of substantially meaningless terms as the "Unknowable." No doubt it serves the turn of a good many feeble sceptics. It sounds less offensive than "Atheism." An Agnostic may safely be invited to dinner, while an Atheist would pocket the spoons. But this pandering to "respectability" is neither in the interest of truth nor in the interest of character. An Atheist is without God; an Agnostic does not know anything about God, so he is without God too. They come to the same thing in the end. An Agnostic is simply an Atheist with a tall hat on. Atheism carries its own name at the Hall of Science; when it occupies a fine house at Eastbourne, and moves in good society, it calls itself Agnosticism. And then the Churches say, "Ah, the true man of science shrinks from Atheism; he is only an Agnostic; he stands reverently in the darkness, waiting for the light." Nor is this the only way in which Professor Huxley has helped "the enemy." He is, for instance, far too fond of pressing the "possibility" of miracles. We have no right, he says, to declare that miracles are impossible; it is asserting more than we know, besides begging the question at issue. Perfectly true. But Professor Huxley should remember that he uses "possibility" in one sense and the theologians in another. He uses it theoretically, and they use it practically. They use it where it has a meaning, and he uses it where it has no meaning at all, except in an _à priori_ way, like a pair of brackets with nothing between them. When the Agnostic speaks of the "possibility" of miracles, he only means that we cannot prove a universal negative.
