72 THE HUMAN BRAIN. 



we leave it as a problem, -whether there be, or not, an analogous 

 provision for the sensual ganglia, to preserve the level of sense when 

 our senses are annulled; and what the organ is? And the question 

 may be repeated for the spinal cord also, with the insinuation, 

 whether the sympathetic nerve be not its cerebellum? For we 

 regard it as certain that the naturalness and economy of force, and 

 the accumulation, are secured everywhere in the bodily system. 



The above function of the cerebellum has its analogues in every 

 sphere. We see it in thought, which has two elements, viz., that 

 of consciousness and personal energy, and that of natural growth, 

 the first corresponding to cerebrum, the latter to cerebellum. And 

 these are often disparted in individuals. In some there is a prepon- 

 derance of cerebral mind; their thoughts move quickly, but flightily ; 

 as we say, there is a want of balance; a want of body or nature in 

 their minds ; a defect of organic or cerebellar faculty. Their mental 

 movements are random and inharmonious; they do not retain or ac- 

 cumulate wisdom; even repetition does them no good; but they 

 strike out afresh in the vagueness of discourse, with no nature to 

 back them. They have all the senses but common sense, which is 

 the spring, incarnation and harmony of them all. In philosophy 

 or collective thought the same division is visible. Philosophies are 

 made, and also they grow; they are both cerebral and cerebellar. 

 Universal tradition, the largest pressure of common sense, is the 

 philosophical cerebellum. And here we see what complete experi- 

 ments of vivisection have been performed ; and what the result has 

 been in philosophies that cut away the nature, accumulation, force 

 and body of preceding thought; which extirpate the fixed organ on 

 of human growth, or the traditionary cerebellum. Dr. Carpenter, 

 speaking of smaller things, describes to the letter the effects which 

 follow: "It does not seem," says he, "that the animal has in any 

 degree lost the voluntary power over its individual muscles : but it 



cannot combine their actions for any general movement The 



reflex movements, such as those of respiration, remain unimpaired. 

 When an animal thus mutilated is laid on its back, it cannot recover 

 its former posture; but it moves its limbs, or flutters its wings, and 

 evidently is not in a state of stupor. When placed in the erect 

 position j it staggers and fedls like a drunken man; not, however,
