III.
It may seem strange to close this chapter by some remarks on a phenomenon which, both by its internal and external characteristics, belongs to the class of irresistible tendencies—the fatal impulse to suicide. Its affinity with homicidal obsession is undeniable, as is proved by the persons who are tormented, in turn, by the craving to kill others and to kill themselves. However, if self-love, in its positive form, reaches its culminating point in megalomania, it seems to me quite legitimate to maintain that self-feeling, under its negative form, attains its supreme negation in suicide.
Without insisting on a merely accessory point, it is certain that suicide, as a manifestation of emotional life, brings us face to face with a psychological problem as yet insufficiently noticed. If there is an incontestable fact—one which, even among the ancients, was familiar to triteness—it is that in every animal the fundamental, ineradicable instinct is that of self-preservation, of existing, and persisting in existence. Now, suicide, whether voluntary or unreflecting, deliberate or impulsive, is the negation of the fundamental tendency, not a theoretic or partial negation, or one in word only, but in deed and absolute. And the sacrifice of life is not subordinated to some other end which acts by superior attraction, such as devotion to a belief, to friends, to humanity, to one’s country, it is a suppression pure and simple, a liberation desired in and for itself.
The ethnological, moral, and social study of suicide does not form part of our subject, having already been fully worked out.[[155]] Our aim is merely the psychological problem, which we must now define with more precision.
The act of suicide results from two very different mental states, that of reflection and that of impulsion.
In deliberate, reflective, voluntary suicide there is a struggle between two factors: the instinct of conservation and the insupportable state caused by pain (incurable disease, ruin, misery, grief, frustrated ambition, dishonour). Reflection decides, and as pain is always a beginning of destruction, it prefers a total and rapid destruction to a partial and slow one. The act is rational, since it tends towards the lesser evil, or at least what is judged to be such.
Impulsive suicide is harder to explain. A man throws himself suddenly out of a window, poisons himself, cuts his throat. In some cases death has been premeditated, but always appears as a compelling, inevitable force, inexorably claiming its victim; the epithet “irresistible” says everything. To the outside spectator the act appears motiveless, without reason, without cause. It is all the more surprising that the struggle, in this case, is no longer between instinct and reflection, but between two instincts, the conservative and the destructive, of which the one which usually is the strongest succumbs, and the individual turns against himself the destructive tendency originally destined to act on others.
Yet the psychology of deliberate suicide gives us the key to that of the impulsive variety. What in the first case results from conscious, clear, reasoned motives, results in the second from blind, obscure, unconscious states: it is an act of organic life, and its cause is found in cœnæsthesia. Impulsive suicide is the expression of the destructive process, slow, permanent, dimly felt, going on in the depths of the organism. Any one who presses in rage on an aching tooth, who rolls on the ground, strikes his head against the wall, or mutilates himself, is attempting an instinctive though absurd reaction in order to get rid of his pain. These are modified forms, it is true, but they will serve to show that the man who yields to an overmastering impulse to strangle or drown himself seeks a deliverance of the same kind.
Leaving degeneration (which is perpetually being dragged into this question) out of account, observation shows us that the difference between the two forms of suicide is reduced to that between psychic and purely organic causes. Impulsive suicide flourishes best on the soil of melancholia and hypochondria—i.e., in states which involve deep dejection and a disorganisation of vital action. We may also notice the part played (as was long ago pointed out) by heredity, the descendants of suicidal ancestors often killing themselves at the same age and in the same manner as the latter;[[156]] now, psychological heredity is based on organic. Finally, the automatic character of these impulses approximates them to the class of reflex actions, attempts at suicide being repeated in the same form during a recurrence of the same circumstances—e.g., somnambulism, intoxication, the menstrual period. All these characteristics assign to irresistible suicide an organic origin, which is equivalent to saying that its ultimate cause lies in temperament. The conservative instinct exists in all men, but it may exist in any degree. In some there is an innate joy of life capable of resisting all disasters; in others, a constitutional melancholy, or (which comes to the same thing) the conservative instinct is very weak and yields to the least shock. Impulsive suicide represents self-feeling at its last stage of regression, or, in other words, at its negative extreme.
