and it makes his life into a mobile drama, of which he is implicitly
conscious, of acts and emotions, of impulses, desires, and suspicions.

This inward form of emotional life and psychical and organic action,
into which the whole value of personal existence is resolved, may be
said to invest and modify all the animal's active relations to the
external world, which it vivifies and modifies according to its own
image. The subsequent act of doubling the faculties which takes place in
man does not occur in the animal; a process which modifies through the
intellect the spontaneous and primitive act. Consequently, the active
and inward sense which is peculiar to the animal is renewed in him by
the external things and phenomena of nature which stimulate and excite
him.

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
himself 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
