"If, then, all organic instincts are conservative, historically acquired, and directed towards regression, towards reinstatement of something earlier, we are obliged to place all the results of organic development to the credit of external, disturbing, and distracting influences. The rudimentary creature would from its very beginning not have wanted to change, would, if circumstances had remained the same, have always merely repeated the same course of existence.... It would be counter to the conservative nature of instinct if the goal of life were a state never hitherto reached. It must be rather an ancient starting point, which the living being left long ago, and to which it harks back again by all the circuitous paths of development.... _The goal of all life is death...._ "Through a long period of time the living substance may have ... had death within easy reach ... until decisive external influences altered in such a way as to compel [it] to ever greater deviations from the original path of life, and to ever more complicated and circuitous routes to the attainment of the goal of death. These circuitous ways to death, faithfully retained by the conservative instincts, would be neither more nor less than the phenomena of life as we know it." Freud puts forth these interesting suggestions with much modesty, admitting that they are vague and uncertain and (what it is even more important to notice) mythical in their terms; but it seems to me that, for all that, they are an admirable counterblast to prevalent follies. When we hear that there is, animating the whole universe, an _Elan vital_, or general impulse toward some unknown but single ideal, the terms used are no less uncertain, mythical, and vague, but the suggestion conveyed is false--false, I mean, to the organic source of life and aspiration, to the simple naturalness of nature: whereas the suggestion conveyed by Freud's speculations is true. In what sense can myths and metaphors be true or false? In the sense that, in terms drawn from moral predicaments or from literary psychology, they may report the general movement and the pertinent issue of material facts, and may inspire us with a wise sentiment in their presence. In this sense I should say that Greek mythology was true and Calvinist theology was false. The chief terms employed in psycho-analysis have always been metaphorical: "unconscious wishes", "the pleasure-principle", "the Oedipus complex", "Narcissism", "the censor"; nevertheless, interesting and profound vistas may be opened up, in such terms, into the tangle of events in a man's life, and a fresh start may be made with fewer encumbrances and less morbid inhibition. "The shortcomings of our description", Freud says, "would probably disappear if for psychological terms we could substitute physiological or chemical ones.
