I add one purely pedantic note which comes, as a note naturally should, at the beginning of the book. These essays are concerned only to discuss the actual fact that the central Christian theology (sufficiently summarized in the Apostles' Creed) is the best root of energy and sound ethics. They are not intended to discuss the very fascinating but quite different question of what is the present seat of authority for the proclamation of that creed. When the word "orthodoxy" is used here it means the Apostles' Creed, as understood by everybody calling himself Christian until a very short time ago and the general historic conduct of those who held such a creed. I have been forced by mere space to confine myself to what I have got from this creed; I do not touch the matter much disputed among modern Christians, of where we ourselves got it. This is not an ecclesiastical treatise but a sort of slovenly autobiography. But if any one wants my opinions about the actual nature of the authority, Mr. G.S.Street has only to throw me another challenge, and I will write him another book. II THE MANIAC Thoroughly worldly people never understand even the world; they rely altogether on a few cynical maxims which are not true. Once I remember walking with a prosperous publisher, who made a remark which I had often heard before; it is, indeed, almost a motto of the modern world. Yet I had heard it once too often, and I saw suddenly that there was nothing in it. The publisher said of somebody, "That man will get on; he believes in himself." And I remember that as I lifted my head to listen, my eye caught an omnibus on which was written "Hanwell." I said to him, "Shall I tell you where the men are who believe most in themselves? For I can tell you. I know of men who believe in themselves more colossally than Napoleon or Caesar. I know where flames the fixed star of certainty and success. I can guide you to the thrones of the Super-men. The men who really believe in themselves are all in lunatic asylums." He said mildly that there were a good many men after all who believed in themselves and who were not in lunatic asylums. "Yes, there are," I retorted, "and you of all men ought to know them. That drunken poet from whom you would not take a dreary tragedy, he believed in himself. That elderly minister with an epic from whom you were hiding in a back room, he believed in himself. If you consulted your business experience instead of your ugly individualistic philosophy, you would know that believing in himself is one of the commonest signs of a rotter. Actors who can't act believe in themselves; and debtors who won't pay. It would be much truer to say that a man will certainly fail, because he believes in himself. Complete self-confidence is not merely a sin; complete self-confidence is a weakness. Believing utterly in one's self is a hysterical and superstitious belief like believing in
