CH. II.] INSTINCTS, PASSIONS. 57 



same time taking into consideration the intervention of the 

 spontaneous conceptions which they produce in the mind, and 

 which commingle with the former, according to their laws. 

 Now, when the sensational desires and aversions manifest their 

 workings in the economy as in the former case, they can be 

 explained and deduced by the laws of action of the external 

 impressions of the sensational stimuli on the cerebral forces; 

 but in the latter case, we must bear in mind the concurrence 

 of the spontaneous intervention of the conceptive force. The 

 first class, therefore, being almost as fully developed as external 

 sensations, may be termed wholly sensational^ but the latter 

 being more like conceptions of the understanding in their 

 origin, are more spontaneous or more physiologically free (27). 

 In the latter, the mind is necessarily conscious of the inter- 

 vening conceptions ; in the former, it need not be conscious 

 of either the conception or of the external impressions of the 



;nsational stimuli, out of which the conceptions are formed. 

 Note. — It is not possible, in this stage of the work, to render 

 this matter clearer ; subsequently (564, 579) it will be made 



lore intelligible. 



Instincts, Passions. 



90. A strong and wholly sensational desire, which arises from 

 [obscure sensational stimuli, and the material ideas of which are 



jonsequently little- developed in the brain (26), is termed a 

 Hind impulse {instinct, sympathy, sensual propensity, sensual 

 \inclination, natural instinct generally), (295) ; an analogous 

 aversion is a blind abhorrence {antipathy, sensual dislike, enmity); 

 I both are sensational instincts (''the flesh'^). They are divided 

 into the instincts of self-preservation, self -maintenance, the pro- 

 pagation of the species, and love of offspring. 



91. Strong desires and aversions arising from confused sen- 

 sational stimuli, of which there is a consciousness, although 

 it is indefinite, and the material ideas of which are more de- 

 veloped in the brain than those of the sensational instincts (26), 

 are termed passions, emotions, affections. Those arising from 

 the sensational stimuli of pleasure are termed pleasing ; those 

 from the sensational stimuli of pain, painful. 



92. In every sensational instinct, and in each passion, we 

 must distinguish :
