Victory of Knowledge over Radical Evil.—It proves a material gain to him who would attain knowledge to have had during a considerable period the idea that mankind is a radically bad and perverted thing: it is a false idea, as is its opposite, but it long held sway and its roots have reached down even to ourselves and our present world. In order to understand ourselves we must understand it; but in order to attain a loftier height we must step above it. We then perceive that there is no such thing as sin in the metaphysical sense: but also, in the same sense, no such thing as virtue; that this whole domain of ethical notions is one of constant variation; that there are higher and deeper conceptions of good and evil, moral and immoral. Whoever desires no more of things than knowledge of them attains speedily to peace of mind and will at most err through lack of knowledge, but scarcely through eagerness for knowledge (or through sin, as the world calls it). He will not ask that eagerness for knowledge be interdicted and rooted out; but his single, all powerful ambition to know as thoroughly and as fully as possible, will soothe him and moderate all that is strenuous in his circumstances. Moreover, he is now rid of a number of disturbing notions; he is no longer beguiled by such words as hell-pain, sinfulness, unworthiness: he sees in them merely the flitting shadow pictures of false views of life and of the world.
