The conative function of emotion.—I shall take up in a later lecture[[223]] (in connection with the psychogenesis of multiple personality) the instincts and sentiments for discussion in more detail. The point to which I wish in this connection to call attention is that when a simple emotion-instinct, or an idea linked with an instinct (a sentiment) is awakened by any stimulus, its impulsive force is discharged in three directions: the first is toward the excitation of those articulated movements and ideas which guide and carry the instinct to fruition—to fight in the case of anger, to flee in the case of fear, to cherish in the case of love, etc. Second (accessory to the first) the excitation of many of the various visceral functions which we have reviewed reinforces the instinctive movements; e. g., for pugnacity or flight the increased respiration and activity of the heart increase the supply of oxygen and blood to the muscles; the secretion of sweat regulates the temperature during increased activity, the increased secretion of adrenalin and the increased secretion of sugar may, as Cannon suggests, respectively keep up the emotional state (after the cause of the fear or anger has subsided) and meet the demand of the muscles for an extra supply of food, etc.
Later experiments of Cannon seem to show that the adrenal secretion removes the fatigue of muscles; and, further, that stimulation of the splanchic nerves will largely recover fatigued muscles, increasing the efficiency as much as 100 per cent.[[224]] As emotion discharges its impulses along splanchic pathways to the adrenal glands, the inference as to the function of emotion in overcoming fatigue is obvious.
As to the sensory accompaniments of emotion, it is quite reasonable to suppose that their rôle is to supplement and reinforce in consciousness the affect, thereby aiding in arousing the individual to a full appreciation of the situation and to such voluntary effort (whether to guide and assist the instinct to its fulfillment or to repress it) as, in the light of past experiences, his judgment dictates. These sensory disturbances on this theory act as additional warnings in consciousness where the affect proper might be too weak.[[225]] Their function would be like that of pain in the case of organic disease. Pain is a biological reaction and a warning to the individual to rest the diseased part,[[226]] as well as a danger signal.
The third direction which the discharge of the impulsive force of the emotion takes is toward the repression of the conflicting conative force of such other emotions as would act in an antagonistic direction.[[227]] The utility of the discharge in this direction is supplementary to that of the excitation of the visceral functions: the former protects against the invasion of counteracting forces, the latter strengthens the force of the impulse in question.
Conflicts thus arise. When an emotion is aroused a conflict necessarily occurs between its impulse and that of any other existing affective state, the impulse of which is antagonistic to the aim of the former. Consequently instincts and sentiments which, through the conative force of their emotion, tend to drive the conduct of the individual in a course in opposition to that of a newly aroused emotion (instinct) meet with resistance. Whichever instinct or sentiment, meaning whichever impulse, is the stronger necessarily downs the other; inhibits the central and efferent parts of the process—ideas, emotions and impulses—though the afferent part conveys the stimulus to the central factor. Thus processes of thought to which the inhibited sentiment or instinct would normally give rise, or with which it is systematized, are likewise inhibited and behavior correspondingly modified. These statements are only descriptive of what is common experience. If one recalls to mind the principal primary emotions (instincts) such as the sexual, anger, fear, tender feeling, hunger, self-abasement, self-assertion, curiosity, etc., this is seen to be an obvious biological truth.[[228]] Fear is suppressed by anger, tender feeling, or curiosity (wonder), and vice versa; hunger and the sexual instinct by disgust.
What is true of the primitive instincts and their primary emotions is also true of compound instincts (emotions) and of sentiments, i.e., ideas about which one or several emotions are systematized. We may, therefore, for brevity’s sake, speak of a conflict of ideas or sentiments or emotions or instincts indiscriminately. In other words, any affective state may be suppressed by conflict with another and stronger affective state. A timid mother, impelled by the parental instinct, has no fear of danger to herself when her child is threatened. The instinct of pugnacity (anger) in this case not being antagonistic (in conflict) is not only not suppressed but may be awakened as a reaction to aid in the expression of the parental instinct. Per contra, when anger would conflict with this instinct, as when the child does wrong, the anger is suppressed by the parental instinct. Conversely, the sentiment of love for a particular person may be completely suppressed by jealousy and anger. Hatred of a person may expel from consciousness previous sentiments of sympathy, justice, pity, respect, fear, etc. The animal under the influence of the parental instinct may be incapable of fear in defense of its young, particularly if anger is excited. Fear may be suppressed in an animal or human being if either is impelled by great curiosity over a strange object. Instead of taking to flight, the animal may stand still in wonder. Similarly in man, curiosity to examine, for example, an explosive—an unexploded shell or bomb—inhibits the fear of danger often, as we know, with disastrous results. The suppression of the sexual instinct by conflict is one of the most notorious of the experiences of this kind in everyday life. This instinct cannot be excited during an attack of fear and anger, and even during moments of its excitation, if there is an invasion of another strong emotion the sexual instinct at once is repressed. Under these conditions, as with other instincts, even habitual excitants can no longer initiate the instinctive process. Chloe would appeal in vain to her lover if he were suddenly seized with fright or she had inadvertently awakened in him an intense jealousy or anger. Similarly the instinct may be suppressed, particularly in men, as every psycho-pathologist has observed, by the awakening of the instinct of self-subjection with its emotion of self-abasement (McDougall) with fear, shown in the sentiments of incapacity, shame, etc. The authors of “Vous n’avez rien à declarer” makes this the principal theme in this laughable drama. Indeed the principle of the suppression of one instinct by conflict with another has been made use of by writers of fiction and drama in all times.
This principle of inhibition by conflict allows us to understand the imperative persistence (if not the genesis) of certain sexual perversions in otherwise healthy-minded and normal people who have a loathing for such perversions in other people but can not overcome them in themselves. H. O., for example, has such a perversion, and yet the idea of this perversion in another person excites a lively emotion of disgust. In other words, at bottom, as we say, she is right-minded. How then account for the continuance of a self practice which she reprobates in another, censures in herself, and desires to be free of, and why does not the instinct of repulsion, and the sentiment of self respect, etc., act in herself as a safeguard? Introspective examination shows that when the sexual emotion is awakened, disgust and the sentiments of pride and self respect are suppressed, and the momentarily activating instinct determines all sorts of sophistical reasoning by which the perversion is justified to herself. As soon as the instinct accomplishes its aim it becomes exhausted, and at once intense disgust, meeting with no opposition, becomes awakened and in turn determines once more her right-minded ideas. Based upon this mechanism one therapeutic procedure would be to organize artificially so intense sentiments of disgust for the perversion and of self-respect that they would suppress the sexual impulse.[[229]]
Likewise the intense religious emotions (awe, reverence, self-abasement, divine love, etc.) may, if sufficiently strong, suppress the opposing instincts of anger, fear, play, and self-assertion, and emotions compounded of them. Examples might be cited from the lives of religious martyrs and fanatics.
If it is true that “the instincts are the prime movers of all human activity,” and that through their systematic organization with ideas into sentiments they are so harnessed and brought under subjection that they can be utilized for the well-being of the individual; and if through this harnessing the immediate promptings of the emotions are brought under volitional control, then all conduct, in the last analysis, is determined by the conative force of instincts[[230]] (and other innate dispositions) harnessed though they be to ideas. For though volition itself can control, reinforce, and determine the particular sentiment and thus govern conduct,—reinforce, for instance, a weaker abstract moral sentiment so that it shall dominate any lower brutish instinct or sentiment with which it conflicts, still, volition must be a more complex form of conation and itself issue from sentiments.
We need not enter into this troublesome problem of the nature of the will;[[231]] nor does it concern us. It is enough for our purpose to recognize that volition can reinforce a sentiment and thus take part in conflicts. In this way undesirable instincts and sentiments can he voluntarily overcome and inhibited or repressed and mental processes and conduct determined.
