the order of ideas and facts which we have observed, so that the process may be as strictly logical as it is practical. Since, in the elements of apprehension, perception is absolutely identical in man and animals, its primitive effects in animating natural phenomena are the same. But man, by means of his reduplicative faculty, retains a mental image of the personified subject which is only transitory in the case of animals, and it thus becomes an inward fetish, by the same law, and consisting of the same elements as that which is only extrinsic. These phantasms are, moreover, personified by the classifying process of types, they are transformed into human images, and arranged in a hierarchy, and to this the various religions and mythologies of the world owe their origin. Since such a process is also the condition and form of knowledge, the source of myth and science is fundamentally the same, for they are generated by the same psychical fact. It is in this way that the progress of human intelligence was developed in the course of ages; its attitude varies in various races, but the impulses, the faculty, and its elements are identical. I do not think that this unique fact in which myth and science have their source has been observed before; still less has any one defined the limits of human intelligence, and recognized in the simple acts of animals the formal and absolute conditions of human science, and the origin of myth.

If I am not deluded by a prejudice in favour of my own researches, this theory is a contribution to truth. It is confirmed by the solidarity which it establishes between the acts and laws of the psychical human faculty, and that of animals which necessarily preceded it. No science can be constituted without such solidarity; this great truth was felt and, after their manner, demonstrated by scholastic philosophers, or, as it was afterwards scientifically expressed by the genius of Leibnitz: Natura non facit saltum !

CHAPTER VI.

THE INTRINSIC LAW OF THE FACULTY OF APPREHENSION.

WE have now carefully considered the acts and dynamic activity of human thought. We have seen in what animal and human perception consists, and how it acts; how the subjects developed in our imagination are gradually united in specific forms or types, and are arranged in a system, whence follow the first symbolic representations of science. But our task is not yet accomplished, since much more is needed to display all that this fact involves, so that we may fully understand the inward evolution of myth and science in history and in our race, and not merely in the individual man.

The faculty and its effects, which could primarily be reduced to this unique and indivisible fact, do not exclusively belong to primordial ages, but go on through all time, our own included, while assuming divers forms and fresh aspects as the faculty of the intellect becomes more developed. It is an indisputable truth that the influence of myth on thought

and fancy, a survival from prehistoric ages, still prevails among the common people both in town and country, among those who are uncultivated, and even in the higher classes conventionally called good society.

It is more difficult to trace the occasional existence of the same influence among those who think rationally and investigate the laws of the universe while acquainted with the earlier mythical process; and yet, as we shall show, the greatest and most able men are not unfettered by it. Myth has hitherto been regarded as a secondary and fanciful product of the psychical human faculty, due to extrinsic impulses, rather than as the primitive and intrinsic necessity of the intelligence-a necessity which has its roots in animal intelligence itself; and the unique fact which generates both myth and science has not been ascertained. If this fact and law had been discovered before, we should have more readily understood religions, philosophic systems, and the successive forms of science, and pure reason would have made more rapid progress. Our theory, besides giving a rational explanation of the different forms assumed by thought in the course of its historic evolution, will, I hope, also account for many psychological phenomena which have hitherto been imperfectly understood, such as dreams, hallucinations, the aberrations of insanity, and the like. The primitive fact and its effects reappear in these conditions, and this influence is persistent and

enters into all our acts, conscious or unconscious, voluntary or involuntary.

It follows from the innate necessity of the perception that objects and their extrinsic and intrinsic causes are resolved into living subjects, and are classified in a hierarchy of specific types, which are accepted by the primitive and ignorant mind as the universal mythical forms.* But the necessities of human speech, which is however involved in mythical representations, from the very beginning essentially reflex, require other terms than those of individual and specific animations. It is clear that the simple personifying faculty of the intellect sufficed in its earliest emotions, but that after the slow development of psychical reduplication, and the enlargement of languages and ideas, it no longer satisfied the logical requirements of the mind.

Consequently, explicit,—that is, rational-singular, and specific ideas gradually arose and assumed a definite form; they were interwoven and fused into these individual and specific types, and thus obtained a place in the thoughts and language of primitive man. The gradual intrusion of specific rational ideas is natural to the human mind, since it is logically progressive, and the fact may be observed by those who watch the mental growth of children, and of ignorant and untaught adults.

*This great truth was observed by Vico, the most advanced of modern psychologists, in his views of primitive psychology.
