The objects and phenomena obvious to perception are therefore supposed by primitive man, as well as by animals, to be conscious subjects in virtue of their constitution, and of the innate character of sensation and intelligence. So that the universal personification of the things and phenomena of nature, either vaguely, or in an animal form, is a fundamental and necessary fact, both in animals and in man; it is a spontaneous effect of the psychical faculty in its relations to the world. We think that this truth cannot be controverted, and it will be still more clearly proved in the course of this work. Such a fact, considered in its first manifestation and in the laws which originally govern it in animals, and in man as far as his animal nature is concerned, assumes a fresh aspect, and is of two-fold force when it is studied in man after he has begun to reason, that is, when his original psychical faculty is doubled. The animation and personification of objects and phenomena by animals are always relative to those of the external world; that is, animals transfuse and project themselves into every form which really excites, affects, alarms, allures, or threatens them; and the spontaneous psychical faculty which such a vivifying process always produces necessarily remains within the sphere of their external perceptions and apprehensions. In a word, they live in the midst of the objective nature, which they animate with consciousness and will, and their internal power is altogether absorbed in this external transformation. In man, in addition to this animation of the things and phenomena of the external world, another more profound and vivid animation takes place, the animation not merely of external forms, but of internal perceptions, ideas, sentiments, and all kinds of emotions. We know that man has not only the perception of external and internal things, but also the perception of this perception. Hence the external form, or the internal sentiment and emotion, may by the dominion of his will over all the attributes of his intelligence be once more subjected to his deliberate observation and intuition; by this process the external and internal world are doubled in their intrinsic ideal, and give birth to analysis and abstraction, that is, to the specification and generalization of the things observed.
