The difficulty then which confronts the ethical writer is that the attitude of detachment possible in other branches of investigation is found to be impossible when one attempts to sound the profundities of that kind of inner experience which is called ethical. The self obtrudes itself at every point, and it instinctively refuses to be humbled. What may be denominated the struggle for self-esteem has indeed played a leading rôle both in the outer and inner history of mankind. This struggle, whose immense importance is often overlooked, accounts for even more interesting facts than the biological struggle for existence. The desire to exercise power over others, often ruthless in the means adopted, is frequently nothing more than a miserable attempt to save self-esteem by covering up the inner sense of the weakness of the self. But the same struggle penetrates also into the realm of theoretical ethics with which we are concerned. Here it tampers with the standards which mortify self-esteem, by inventing such ethical theories as seem to make the problems of personality easy of solution, and by blinking the tragic facts of guilt, remorse, etc. Various ethical systems that are in vogue at the present time are, at least in part, exemplars of this process—the theory for instance that ethics is nothing more than a calculus of self-interest, or a matter of sympathetic feeling, or a balancing of the more refined against the grosser pleasures. The instinct of self-preservation, in the shape of the preservation of self-esteem, is quite incorrigible, and against its insidious suggestion we have reason to be particularly on our guard in the discussion which we are entering. Are we then to refrain, out of sheer regard for decency, from touching on this subject at all? Is everyone who writes on ethics, or attempts to teach it, either a pedant or a hypocrite? But we cannot avoid discussing it, nor resist the impulse to teach and write about it, for it is the subject on which more than any other we and others sorely need help and enlightenment. And we shall get help in the endeavor to afford it to others. This, then, is my position: I do not presume to lay down the law for anyone. I find that I can set forth the better standards which in the course of trial and error I have come to recognize. I would not shamelessly expose mere private failures and failings after the manner of Rousseau in the “Confessions”; for there is a tract of the inner life which ought to be kept from publicity and prying intrusion. I shall then deal with deflections only in so far as they can be traced to false standards or principles, and as they tend to illustrate the flaw in those standards and principles.
