1 88 Scientific Sophisms. 



brain is the badge. The attempts that have 

 been made to minimize, and even to efface its 

 significance, will be noticed in the sequel ; 

 but the force and effect of that significance are 

 not to be invalidated and cannot be impaired 

 by disputations in detail. The one broad cha- 

 racteristic fact remains beyond dispute : all 

 healthy human brains are structurally perfect ; 

 but the highest brute brains are structurally 

 imperfect. The human brain is pleno-cerebral ; 

 all other brains are manco-cerebral. The 

 human brain, in its least cultivated manifes- 

 tations, retains the latent franchise of progres- 

 sive reason ; all other brains exhibit the rigid 

 circumscription of unprogressive instinct. No 

 brute is susceptible of human culture ; while, 

 on the other hand, of that culture there is no 

 human infant that is not susceptible. Between 

 these two, the difference thus seen is nothing 

 less than a difference absolutely immeasurable.
