1004 Dynamic Theory. 



desire it, since his appetite is never satisfied. He is like a man with a 

 tape worm, who gets no satisfaction from what he eats, but constantly 

 desires more. If the money maker were forcibly restrained from seek- 

 ing more, after he has enough, his attention would be turned to the as- 

 similation, and the enjoyment and love of what he has. An excess 

 of the conditions that produce pleasure or satiety, brings a pall. Too 

 much of that which creates love causes a "sickish sweet," and finally a 

 disgust. Love, joy, and gladness, indicate states of satisfaction, 

 bounded on one side by desire, and on the other by disgust. 



As hunger is the type of the positive sensations, so nausea is the type 

 of the negative ones. The physical basis of these is repulsion instead of 

 attraction. In electricity two bodies that at first attract each other in a 

 short time come to be charged alike and then they repel. If they are 

 charged alike in the first place they repel from the first. This illus- 

 trates if it does not state the identical case of the basis of the negative 

 sensations, these sensations being the reflections of conditions of re- 

 pelling or antagonistical movements in certain tissues. The sensations 

 that come under this designation are such as disgust, dislike, aversion, 

 hatred, anger, rage, melancholy, sorrow, dread, alarm, fear, fright, 

 terror, panic, &c. Those sensations that represent satisfaction and 

 balance in the polar condition of the tissues are pleasurable, and on 

 one side of these are the sensations that represent unsatisfied attractive 

 bonds, and on the other those representing repelling elements. Both of 

 these are in a greater or less degree uneasy and painful. (See chap. 67). 

 The final tissues involved in these sensations in man and the higher 

 mammals appear to be those of the brain, or at least those are the ones 

 which together form the seat of the general consciousness; and although 

 the conditions of the tissues of the body generally, such as the muscles, 

 the stomach, the sexual glands, the liver, heart, kidneys. &c. , consti- 

 tute the bases of very many of the sensations both pleasurable and 

 painful, there are many others which arise only from conditions in the 

 internal sense organs of the brain and the manner in which they are af- 

 fected by new incoming stimulations from the environment, as pointed 

 out on page 712. The organs of thought are a part of the environ- 

 ment to the organs of sensation, so that their states, as before observed, 

 furnish a large share of the stimulations by which organs of sensation 

 are set up in the first place, and revived in recollection afterwards.

THEOLOGICAL CONSIDERATIONS. 



If the conclusions reached in the foregoing chapters are correct, I 

 think it must be admitted that they subvert the theory of the immortal-
