When a well broken horse, for example, goes on his way quietly, perceiving nothing which strongly attracts nor alarms him, the sudden flutter of a cloth, the flaring of a lamp, the rush of water, or some violent noise will cause him to stop, to plunge and kick, or to bolt away. We have already shown, by experiment, the exciting cause of his alarm and suspicion. The sudden fluttering of the cloth in the wind was a phenomenon perceived by the horse, and since he regarded this phenomenon as an animated subject, and consequently as a real power, it is evident that his fear was caused by the sudden appearance of a living form, and the direct apprehension of a subject which might possibly be hurtful or dangerous. In this way, the circle is completed and combined in one unique phantasm; a phenomenon, a living subject, and a real power.

In this instance, the psychical law is so clear that it can hardly be disputed. But if we consider any other animal perceptions, we find that the law still holds good, as we have already shown in various instances. In all cases the apprehension takes place in the same way, and consists of the same elements, namely, of a phenomenon, a living subject, and a real power. The exercise of animal apprehension is the rapid, necessary, and perpetual concentration into a single image of the phenomenon, subject, and cause; that is, given the perception of a phenomenon, the animal endows it, with respect to himself, with consciousness, and consequently with real power.

In fact, the faculty of perception cannot be exercised in any other way, nor can it consist of any other elements. In nature, the sensible qualities of things are all resolved into general and special phenomena, appearances, and extrinsic forms, as far as animal and human intuition, and the character of the subject which perceives and feels them, are concerned; and they are perceived just so far as we and as animals are able to communicate by means of our senses with the world and with ourselves. A phenomenon and an intrinsic form signify, at the moment of perception, the thing, the object which the conditions of our senses enable us to perceive, and the intrinsic power of this phenomenon implies a cause. Natural phenomena and beings are thus reciprocally linked together as causes and effects, an effect becoming in its turn the cause of a subsequent fact; that is, when we consider things in themselves, and not relatively to the animal or man who apprehends them.

If, therefore, there are in animal consciousness and intelligence three elements of apprehension, afterwards fused into a single fact, it follows that the extrinsic relations of beings and forces are subjectively reciprocal; there is the given form of a phenomenon, and, intrinsically, it consists of an active power, eternally at work, since there is no being nor form which stands still and is not reproduced in the infinite evolution of the universe.

Since, to the percipient, the extrinsic form, whatever it may be, remains the same as that which was first presented to him, the phenomenon is bounded by his faculty of perception, followed by the immediate and implicit assumption of a subject, and consequently of a possible and indefinite causality. This internal and psychical process of the animal corresponds with the actual condition of things, as they appear and really are; a correspondence which is in itself a powerful confirmation of the truth.

Since an animal is devoid of the explicit and reflex process of the intellect, it has not and cannot have any conception of the thing in itself, the intrinsic essence of the phenomenon, nor yet of the objective and cosmic cause; because it animates the phenomenon with its own personality, which has assumed the external form of this phenomenon, it is conscious of a cause, like itself, transfused into the object in question. We have shown that phenomena affect animals in this way, and that they are conscious of being in a world of living subjects, constantly actuated by the deliberate purpose of influencing them.

The faculty and elements of apprehension are precisely similar in man and animals, since extrinsic things present the same appearance to both alike, and the perceptive power acts in the same way. We cannot, indeed, go back to our first beginnings, and it is difficult for those who are not accustomed to such researches to discover the primitive facts of their own being, which have been so much modified by exercise and the intrinsic use of reflection for many ages; yet some certain signs remain, nor would it be now impossible to reproduce them. No one can doubt that man also began to communicate with the world and with himself by his perception of a phenomenon, of some extrinsic quality or form. From this he directly apprehended the thing and its cause. No intelligent person can believe that man had any direct intuition of the thing in itself, independently of the extrinsic phenomenon by which it was presented to his perceptions: he could not by the sudden apprehension of all natural objects intuitively grasp the Idea. This will be more fully shown in the following chapter.

In accordance with this statement, man, who still retains his animal nature, has exercised the same faculty of apprehension by the synthetic process of the three elements which compose it in the case of animals; he attains therefore to the same results, that is, he animates the object of perception, and considers it as an efficient cause. This identical faculty of perception in man and animals was only differentiated when the reflex power of man subsequently enabled him to regard objects, as we do now, as inanimate, and subject to the universal laws of nature.

Even now, after all our scientific attainments, we are not wholly free from the former innate illusion; we often act towards things as if we lived in the early days of our race, and continue that primitive process of personification in the case of certain objects.

We have shown what was the origin of the fetish and of myth, and how it arose from the impersonation of all natural objects and phenomena, which are transformed into living subjects. This shows that the faculty, elements, and results of the apprehension are identical in man and animals. If man created the fetish which in process of differentiation generated all kinds of myths, he, like animals, was directly and implicitly conscious of the living subject, and in it of an active cause. Although in man the fetish retains its personality in his memory, and becomes the cause of hopes and fears throughout his life, while its effect on the animal is only transitory, and at the actual moment of perception; yet this does not invalidate the truth of the principle, nor prove that their impulses and genesis are not identical. Thus the analysis of the faculty of apprehension confirms and explains the proof before given of the origin of myths, and explains their causes.
