I conceive the human reason to be the antagonist of all known forces other than itself, and that therefore its most essential character is the hope and desire to control and transform the universe; or, failing that, to annihilate, if not the universe, at least itself and the consciousness of a monster fact which it entirely condemns. In this conception I believe myself to be at one with those by whom men have been most influenced, and who, with or without confidence in the support of unknown powers, have set themselves deliberately against the face of things to die or conquer. This being so, and man individually weak, it has been the avowed object of great characters--carrying with them the instinctive consent of nations--to establish current values for all things, according as their imagination could turn them to account as effective aids of reason: that is, as they could be made to advance her apparent empire over other elemental forces, such as motion, physical life, &c. This evaluation, in so far as it is constant, results in what we call civilisation, and is the only bond of society. With difficulty is the value of new acquisitions recognised even in the realm of science, until the imagination can place them in such a light as shall make them appear to advance reason's ends, which accounts for the reluctance that has been shown to accept many scientific results. Reason demands that the world she would create shall be a fact, and declares that the world she would transform is the real world, but until the imagination can find a function for it in reason's ideal realm, every piece of knowledge remains useless, or even an obstacle in the way of our intended advance. This applies to individuals just as truly as it does to mankind. And since man's reason is a natural phenomenon and does apparently belong to the class of elemental forces, this warfare against the apparent fact, and the fortitude and hope which its whole-hearted prosecution begets, appear as a natural law to the intelligence and as a command and promise to the reason. The alternative between the will to cease and the will to serve reason, with which I start out, may not seem necessary to all. "Forgive their sin--and if not, blot me I pray thee out of thy book," was Moses' prayer; and to me it seems that only by lethargy can any soul escape from facing this alternative. The human mind in so far as it is active always postulates, "Let that which I desire come to pass, or let me cease!" Nor is there any diversity possible as to what really is desirable: Man desires the full and harmonious development of his faculties. As to how this end may most probably be attained, there is diversity enough to represent every possible blend of ignorance with knowledge, of lethargy with energy, of cowardice with courage.
