CEREBRUM AND CEREBELLUM. 69 



ing life by accordant motions. The voice of the sensual brain fills 

 the body with sensual perceptions and sensual motions : it raises it up 

 to the enjoyment of the cunning of the senses. Whatever is re- 

 quired for their gratification comes from this source in the shape of 

 emotions and organic instincts. Under its influence the organs and 

 viscera are like the animals hunting for their prey; and each takes 

 what it wants from the common stock, as the living creatures take 

 their pabulum from the earth. The organs would indeed do this 

 without these sensual brains, but only as vegetables in a kind of 

 wooden representation. Finally, the cortical surfaces, or the ganglia 

 of thought and will, by their spirits diffuse their own light through 

 the body, so that all and singular the organic acts and processes are 

 done with the tincture of a higher than animal wisdom. All these 

 would be done by the senses, but then their essence would be differ- 

 ent ; as the essence of bee architecture is different from that of hu- 

 man, though not different in its mathematics. 



Thus the human body is all obedience to these three degrees of 

 nerve-spirit, and if it stopped with the reflex actions, it would be but 

 a dramatic mask, involving no wisdom beyond that of supreme mim- 

 icry : and in the same way, if it stopped with the animal brain, it 

 would still involve no wisdom beyond the perfect adaptation of sen- 

 sual means to sensual ends. It does not however stop here; but 

 even its theatricism and animality become instinct with reason and 

 will. And the like process which impregnates sense and motion, 

 as we know them, with reasonable thought and voluntary ac- 

 tion, strikes the same through the secretest parts of the organization, 

 and makes the blood rational, and the bile rational, and in short 

 makes the whole body human by the radiation of that which alone 

 is human, from above its summit. 



But now, in the human being, these upper states are not only 

 fitful, but also intermitting or regularly periodical. Sleep comes to 

 all, and takes away impression, sense and understanding, as well as 

 motion, impulse and will. And in this respect waking too is full 

 of somnolency, or abrogation of our superior powers. "'"If then there 

 were not some provision, sleepless and permanent, to keep us up to 

 the human level, the answerableness of the body to the soul, and 

 consequently the animation of the former, would perish many times
