256 PSYCHOLOGY. 



parts. The first [sympathetic fever] is a consciousness of an injury 

 clone to a part which disturbs the whole : the second [hectic fever] is a 

 consciousness of a local complaint, as if the parts felt themselves 

 unequal to sustain it ; whereby the constitution is teased into an action 

 of which it cannot relieve itself. 



Of the Mind. 



The mind, or sensitive principle, is affected by objects which make 

 impressions, which impressions make an alteration in the parts of 

 sensation, and according to the nature of the impression so is the mind 

 affected. If we see a man dance, the variety of actions produces the 

 same variety of impressions, which impressions have simply an effect 

 upon our minds. If it is a lively or quick dance, and not joined with 

 distortions (which equally affect us), we feel lively ; if it is a grave 

 dance, we feel grave. The effect of the motion simply of other bodies 

 upon our minds arises from an original property in the mind to sym- 

 pathize with the cause of those actions, and to put itself into the same 

 state in which the mind, or cause, is in which produces them ; for, 

 when the actions are various, the impressions are so, and the effect of 

 these impressions is an inclination to put the body into such motions. 

 This facility of a mind to be put into such a state by such impressions, 

 will always be in proportion to the natural turn of that mind ; so that 

 the state of mind, which is naturally desirous of putting the body into 

 certain actions, is also capable of being affected in the same degree by 

 similar actions in another ; so that a lively mind produces lively actions 

 in the same person, and lively actions in another are capable of pro- 

 ducing an increase of this lively mind and action in that same person. 



The mind is not only affected according to the simple impression, as most 

 probably is the case in brutes, but from experience, and association of 

 other impressions or ideas with the present, it arrives at the cause of 

 the actions which produced these impressions ; and this always pro- 

 duces a stronger effect than the simple impression. So that an effect 

 of the mind on the body is capable of producing an impression on the 

 senses of a second body, which shall make the mind of that second 

 body fall into the same state with the first or original mind, which 

 shall produce the same actions in that second body with the first, and 

 they shall all act in concert. For if the mind of the receiver attends 

 to the causes of these actions, while the effects of these causes are 

 producing their effects upon that mind, then the mind is still more 

 affected ; and the effect which arises from reflection is much stronger 

 than that arising- f rum simple sensation or impression.
