60 CEREBRAL FORCES. [i. 



95. A sensational instinct and a passion cease, or are pre- 

 vented being satisfied, either by tlie enfeebling of the sensational 

 stimuli which incite the mind to the strong effort, and this may- 

 occur partly psychologically, partly physiologically, or — by the 

 contentment of the anticipation, or by the prevention of the 

 requisites thereto (81, 94). 



The Free Will. 



96. The motives [Bewegungsgriinde] add the impression of 

 pleasure or suffering to the material ideas of every conception 

 not in equilibrio or passive, and consequently to those of a 

 similar future sensation, which must be stronger in proportion 

 as the feeling of pleasure or suffering is greater, and, according 

 to these views, be able to exercise a corresponding influence in 

 the animal economy (80, 88). But as incitements of the 

 mind, they also excite desires and aversions (83), which are 

 termed intellectual (to will, and not to will, intentions of the 

 will) free conclusions (89), and which arise from an anticipation 

 and expectation of the understanding, and the motives it con- 

 tains (84, 86, 88). The laws of action in this case are the 

 same as laid down in § 94 ; the effort of the cerebral forces is 

 strong in proportion with the strength of the will. 



The Actions excited by the Mind, or Sentient Actions. 

 [Seelenwirkungen] . 



97 — 110. All material ideas (25, 26) with their impressions 

 of pleasure and pain (80) and all efforts of the cerebral forces, 

 so far as they are based on the conceptive force (27), together 

 with all real animal actions in the body dependent thereon 

 (Baumgarten, § 224), are termed actions of the animal-sentient 

 forces, operationes animce, sentient actions. Sentient actions 

 in the body may be divided into two classes : 1 . Those of the 

 perceptive faculty, or, in other words, those of the external sen- 

 sations, of sensational imaginations, forcseeings, and of the 

 understanding [017, 73, 70). 2. Those of the incitements of 

 the feelings (80, 83), including sensational stimuli and motives 

 (88), the desires and aversions (81), the instincts and passions 

 (90, 91), and the will (96). The sentient actions which are 

 excited by an entire conception (" tot ale," Baumgarten, § 378),
