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.
