ANIMAL AND HUMAN PEKCEPTION. 133 



the order of ideas and facts which we have 

 observed, so that the process may be as strictly 

 logical as it is practical. Since, in the elements 

 of apprehension, perception is absolutely identical in 

 man and animals, its primitive effects in animating 

 natural phenomena are the same. But man, by 

 means of his reduplicative faculty, retains a mental 

 image of the personified subject which is only 

 transitory in the case of animals, and it thus 

 becomes an inward fetish, by the same law, and 

 consisting of the same elements as that which is 

 only extrinsic. These phantasms are, moreover, per- 

 sonified by the classifying process of types, they are 

 transformed into human images, and arranged in a 

 hierarchy, and to this the various religions and 

 mythologies of the world owe their origin. Since 

 such a process is also the condition and form ef 

 knowledge, the source of myth and science is funda- 

 mentally the same, for they are generated by 

 the same psychical fact. It is in this way that the 

 progress of human intelligence was developed in 

 the course of ages ; its attitude varies in various 

 races, but the impulses, the faculty, and its elements 

 are identical. I do not think that this unique fact 

 in which myth and science have their source has 

 been observed before ; still less has any one defined 

 the limits of human intelligence, and recognized in 

 the simple acts of animals the formal and absolute 

 conditions of human science, and the origin of myth.
