A cultivated and rational man, by the reflex and calm examination of things, can correctly distinguish these two classes of subjects and phenomena, and cannot as a rule be deceived as to their real and relative value with respect to them and to himself. But when he forgets his primary intellectual condition, and does not perfectly understand the permanent condition of animals, he believes that their faculties are identical, and that things, qualities, and phenomena present the same appearance to the human and the animal perception. Yet the actual nature of the thing, so far as it is estimated by our perception as an object different from ourselves and from any other animal, cannot be so apprehended by animals which lack the analytical faculty in the perennial flow of their perceptions; the actual and inanimate thing is presented to them only by the intrinsic, peculiar, personal, and psychical quality of the animal itself. If form, and characteristic and deliberate action, are wanting to the substances and phenomena of inanimate nature, qualities which more readily arouse in animals the idea of a subject resembling and analogous to themselves, yet there always remains the apprehension of some sort of form in which--not distinguished from the others by reflex action--the inward faculty of sensation and emotion is repeated and impersonated by the perceiving animal. Thus every form, every object, every external phenomenon becomes vivified and animated by the intrinsic consciousness and personal psychical faculty of the animal itself. Every object, fact, and phenomenon of nature will not merely appear to him as the real object which it is, but he will necessarily perceive it as a living and deliberating power, capable of affecting him agreeably or injuriously. Every one is aware of the jealous, suspicious nature of animals, and that they are not only inquisitive about other animals, but about every material object which they see unexpectedly, which moves in an unusual way, or which interferes with or injures them. It must have been often observed how they turn against any object which has chanced to hurt them, or which has annoyed them by regular and repeated motions, how they start at the sudden appearance or oscillation of some unlooked-for thing, at an unusual light, a colour, a stone, a plant, at the fluttering of branches, of clothes, or weathercocks, at the rush of water, at the slightest movement or sound in the twilight, or in the darkness of night. They look about, and consider all things and phenomena as subjects actuated by will, and as having an immediate influence on their lives, either beneficent or injurious.
