CH. 11.] SENTIENT ACTIONS. 61 



without the intervention of another, are termed direct sentient 

 actions ; all others are indirect (incidental) actions of this entire 

 conception. The nature and origin of these various sentient 

 actions may be learnt from the paragraphs to which reference 

 is made. 



111. Although the sentient actions of the various conceptions 

 are developed, and follow each other, partly according to the 

 laws of action of external impressions on the cerebral forces, 

 partly according to psychological laws, still the conceptive force 

 co-operates in each as well as the cerebral forces (25); and con- 

 sequently each may be developed, facilitated, hindered, and 

 interrupted in two different ways ; namely, physiologically, 

 because the actions of the animal machines requisite to each 

 are partly so developed, facilitated, hindered, or interrupted; 

 and psychologically, because the mind has a similar influence 

 on those actions. It has already been shown (45, 46), how the 

 sentient actions of the external sensations, and consequently 

 through these, those of the sensational conceptions, desires, 

 aversions, instincts, and highly sensational passions are physio- 

 logically developed and prevented, in so far as the external 

 sensations themselves are physiologically developed or pre- 

 vented. But it has not been possible hitherto to explain how 

 the sentient actions of the conceptions, desires, &c., are physio- 

 logically developed in the brain out of each other as material 

 ideas, and transmitted to the nerves, for we know nothing of 

 the nature of the cerebral forces, or of the mode in which the 

 conceptions excite the cerebral functions. Nevertheless, we 

 know generally under what conditions these sentient actions 

 are physiologically developed or prevented in the animal ma- 

 chines external to the brain, as we shall subsequently show, 

 (121, &c.) But how all this happens psychologically, is taught 

 by metaphysics ; and therefore in both ways, and on principles 

 entirely dissimilar, sentient actions may be produced, facilitated, 

 and increased ; and, on the contrary, in both ways, and on 

 principles as widely different, they may be prevented, weakened, 

 and destroyed. This is the ground of difference in the nature 

 of diseases of the cerebral forces and sentient actions, which 

 arise both from corporeal and mental causes; and in their 

 therapeutical and psychological treatment.
