140 ANIMAL-SENTIENT FORCES. [i. 



is produced, that constitutes the sensational stimulus of the 

 instinct of propagation, and excites it in the mode described 

 above (268), together with all its sentient actions. — ( Vide 

 Haller^s 'Physiology,^ § 870). It is manifested by the strong 

 effort of the conceptive force to attain the complete development 

 of the highly pleasurable, obscure, foreseen sensation of copula- 

 tion (94), and by the sentient actions which accompany this effort 

 (255). The vital movements, consequently, are powerfully in- 

 fluenced by the instinct itself (251, 258). The heart beats with 

 greater force, the heated blood circulates violently, the respiration 

 becomes a sighing, or a corporeally-produced languishing and 

 moaning, as occur from any other similar heated state of the 

 blood : at the same time, the actions of the future sensation, 

 in the satisfaction of the instinct (in this case copulation), become 

 vividly, although incompletely manifested (257), so that the 

 sexual organs are in the same condition as in copulation, and 

 only the external impression is wanting to the satisfaction of 

 the instinct, which the animal often procures incidentally, 

 often experiences normally in copulation. These only are the 

 true, direct, sentient actions of the instinct. It hardly, how- 

 ever, excites these only in the mind; for other conceptions 

 are conjoined therewith, as subordinate sensations (225), and 

 in particular, spontaneous conceptions, imaginations, foreseeings, 

 imperfect sensations (148), other instincts and emotions, and 

 in men even reflections, and desires, and aversions of the 

 intellect, of which the object that gives pleasure is the exciting 

 cause. For example, similar circumstances are remembered 

 in the instinct with their subordinate impressions, scenes from 

 favorite romances are recollected, new images for the fore- 

 seeing faculty are produced, and pleasurable anticipations ex- 

 cited, which often grow into imperfect external sensations, so 

 that the individual l^ias the beloved object before his eyes, and 

 thinks that he converses with it (148). All movements of the 

 animal in accordance with these conceptions, and even all 

 influences which these conceptions exercise according to their 

 nature, on the mechanical machines of the body, — as singing, 

 chirping, crowing, whining, and all spontaneous enticements to 

 copulation, are not direct actions of the instinct (103), but inci- 

 dental sentient actions, contingent on secondary sensations, or 

 on ideas excited spontaneously, or on secondary conceptions.
