This conception of a priori is, it must be admitted, very different from that of transcendental philosophers, who seek to prove either that an independent artificer has not only produced the various organic forms in their present complexity, and has specially provided the spiritual subject with its category of thought, independently of all experience; or else they assert the intrinsic existence of such forms in the spirit, from the beginning of time.

In this way, as we have already said, we must not only collect the facts which abound in history and ethnology respecting the general teaching of myths, but we must also observe introspectively, and by pursuing the experimental method, the primitive and fundamental psychical facts, so as to discover the a priori conditions of the myth itself. We must ascertain, from a careful psychological examination, the absolutely primitive origin of all mythical representations, and how these are in their turn the actual historical result of the same conditions, as they existed prior to their manifestations.

It must not be supposed that in this primary fact, and in these a priori psychical and organic conditions, we shall find the ulterior cause of the various and manifold forms, or of the successive evolution of myths. This would be a grave mistake, equal to that of transcendentalists, who imagine that the laws which actually exist, and the order of cosmic and historic phenomena may be determined from the independent exercise of their own thoughts, although such laws and order can only be traced and discovered by experience and the observation of facts. In the a priori conditions of the psychical and organic nature, and in the elementary acts which outwardly result from them, we shall only trace the origin and necessary source of myth, not the variable forms of its successive evolution.

The ulterior form, so far as the substance of the myth and its various modifications are concerned, is in great part the reflex work of man; its aspect changes in accordance with the attitude and force of the faculties of individuals, peoples and races, and it depends on an energy to which the a priori conditions, as we have just defined them, do not strictly apply so far as the determinate form is concerned.

It is precisely in this ulterior work of the evolution of myth, which in the elementary fact of its primitive essence had its origin in the predisposition of mind and body, that we may discern the interchangeable germ and origin both of myth and science. If, therefore; the rationale of science cannot be found in the general form of mythical representations, the matter which serves to exercise the mind; yet the mode of its exercise, and of the logical and psychical faculty, and the spontaneous method pursued, are identical: the two mythical and scientific faculties are, in fact, considered in themselves, fused into one.

As far as the origin of myth is concerned, the mode of considering its evolution, and its organic connection with science, we differ from other mythologists as to the sources to which they trace this immense elaboration of the human intelligence. We may be mistaken, but we are in any case entering on unexplored ways, and if we go astray, the boldness of an enterprise which we undertake with diffidence pleads for indulgence.

Omitting to notice the well-known opinions on the origin of myth which were current in classic antiquity, in the Græco-Latin world, or in India,[2] we restrict our inquiry to modern times subsequent to Creuzer's learned and extensive labours. In a more scientific method, and divested of prejudice, we propose to trace the sources of myth in general, and among various peoples in particular.

The science of languages, or comparative philology, is the chief instrument required in such researches, and much light has been acquired in our days, which has led to surprising results, at least within the sphere of the special races to which it has been applied. The names of Kuhn, Weber, Sonne, Benfey, Grimm, Schwartz, Hanusch, Maury, Bréal, Pictet, l'Ascoli, De Gubernatis, and many others, are well known for their marvellous discoveries in this new and arduous field. They have not only fused into one ancient and primitive image the various myths scattered in different forms among the Aryan races, but they have revealed the original conception, as it existed in the earliest meaning of words before their dispersion. Hence came the multiplicity of myths, developed in brilliant anthropomorphic groups in different theologies, gradually becoming more simple as time went on, then uniting in the vague primitive personification of the winds, the storms, the sun, the dawn; in short, of astral and meteorological phenomena.

On the other hand, Max Müller, whose theory of original myths is peculiar to himself, has made use of this philological instrument to prove that the Aryan myths may at any rate be referred to a single source, namely to metaphor, or to the double meaning of words, due to the poverty of primitive languages. He calls this double meaning the infirmity of speech.

I do not deny that many conclusions to which some or other of the great authorities just mentioned have arrived may be as true as they are surprising. I also admit that this may be a certain method of distinguishing the various mythical representations in their early beginnings from their subsequent and complex forms. But in all the facts which have been ascertained, or which may hereafter be ascertained, from the comparative study of the languages of different races, no explanation is afforded of the fact that into the natural and primitive phenomena of myth, or, as Müller holds, into its various metaphors, man has so far infused his own life, that they have, like man himself, a subjective and deliberate consciousness and force. It seems to me that this problem has not yet been solved by scholars; they have stopped short after establishing the primary fact, and are content to affirm that such is human nature, which projects itself on external things.[3]
