ANIMAL AND HUMAN PEECEPTION. 131 



physiological law of his perception, which he has in 

 common with animals, transformed the world and 

 its phenomena into subjects endowed with conscious 

 life; so by his psychical faculty of reduplication he 

 personified the mental images of these same subjects 

 as fetishes and myths ; and subsequently invested 

 them with more distinctly human forms, and also 

 with specific types of humanity. The same faculty 

 and conditions of animal perception afterwards become 

 the true and only causes of the superstitions, mytho- 

 logies, and religions of mankind. The law of con- 

 tinuity is unbroken, and this is a certain confirmation 

 of the truth. 



This faculty, inward function, and process of 

 mythical and symbolic facts led in course of time to 

 the evolution and beginning of knowledge, which is 

 first empirical and then rational. Therefore, we must 

 repeat, the extrinsic and intrinsic perception, the 

 specification of types, and their modification into a 

 unity wiiich was always becoming more compre- 

 hensive, are the conditions and method of science 

 itself, which is only developed by means of this 

 faculty. Hence the elements and intrinsic logical 

 form of science are identical with those through 

 which mythical representations and the inward life 

 of the human intelligence are developed.* 



* A careful reader will not hold this repetition to be unnecessary, 

 since it explains from another point of view the fundamental fact of 

 perception and its results. It is here considered with reference to the 

 three elements which constitute this fact.
