the higher was a sufficient explanation to us of the mystery of existence." Let it be understood, therefore, that science is one thing, and philosophy another: that science most properly concerns itself with matter and motion, and reduces phenomena, as far as it can, to mechanism. The more successfully it does that, the more it fulfils its end and aim; but when, on the strength of that achievement, it seeks to blossom into a philosophy, when it endeavours to conclude that its scope is complete and all-inclusive, that nothing exists in the universe but mechanism, and that the aspect of things from a scientific point of view is their only aspect,--then it is becoming narrow and bigoted and deserving of rebuke. Such rebuke it received from Huxley, such rebuke it will always receive from scientific men who realize properly the magnitude of existence and the vast potentialities of the universe. Our opportunities of exploration are good as far as they go, but they are not extensive; we live as it were in the mortar of one of the stones of St. Paul's Cathedral; and yet so assiduously have we cultivated our faculties that we can trace something of the outline of the whole design and have begun to realize the plan of the building--a surprising feat for insects of limited faculty. And--continuing the parable--two schools of thought have arisen: one saying that it was conceived in the mind of an architect and designed and built wholly by him, the other saying that it was put together stone by stone in accordance with the laws of mechanics and physics. Both statements are true, and those that emphasize the latter are not thereby denying the existence of Christopher Wren, though to the unwise enthusiasts on the side of design they may appear to be doing so. Each side is stating a truth, and neither side is stating the whole truth. Nor should we find it easy with all our efforts to state the whole truth exhaustively, even about such a thing as that. Those who deny any side of truth are to that extent unbelievers, and Huxley was righteously indignant with those shortsighted bigots who blasphemed against that aspect of divine truth which had been specially revealed to him. This is what he lived to preach, and to this he was faithful to the uttermost. Let him be thought of as a devotee of truth, and a student of the more materialistic side of things, but never let him be thought of as a philosophical materialist or as one who abounded in cheap negations.
