ANIMAL SENSATION AND PERCEPTION. 51 



Two kinds of things present themselves to his 

 perception : other animals, of whatever species, and 

 the inanimate objects of the world. As far as the 

 other animals are concerned, which are obvious to 

 his perception, it is perfectly evident that upon these 

 he will project his whole internal life of consciousness 

 and emotions, and will feel their identity with him- 

 self by his implicit and intuitive judgment. And in 

 fact, the movements, sounds, gestures, and forms of 

 other animals necessarily cause this sense of inward 

 psychical identity, whence arises the implicit notion 

 of an animated and personal subject. Any one who 

 observes, however superficially, the conduct of animals 

 to each other when they first meet, cannot doubt 

 this truth for an instant. 



Although the external form and character of 

 the animal perceived are important factors of the 

 implicit notion of an animated personal subject, 

 this belief is even more due to the animal's inward 

 consciousness of himself as a living subject which 

 is reflected in the extrinsic form of the other and 

 is identified with it. The spontaneous and personal 

 psychical effort does not decompose the object per- 

 ceived into its proper elements by means of reflex 

 attention, but it is immediately projected on those 

 phenomena which assume a form analogous to the 

 sentient subject. 



The fact of this law must never be forgotten in 

 the analysis of animal intelligence and sensation.
