We see from this account the mythical origin of all that concerns the organization and genesis of the world, the destinies and nature of the soul, since these are sublimated myths; the elements are first regarded as deities, and the world is made in the image of man, and considered to be alive; the stars and the earth are endowed with life and intelligence; the fate of souls before and after death, their recollection of a prior existence, their transmigrations and wanderings around the tombs, demoniac possession in inspiration and madness, are all very ancient mythical representations, which form a great part of the theoretical and spiritual cosmogony of savages in all times and places. We have seen that not only relatively civilized peoples, but those which are quite savage divide souls into distinct parts: throughout Africa, America, and Asia, there is a belief in the transmigration of souls into animals, plants, and other objects. The Tasmanians believed that their souls would ascend to the stars and abide there; and all savages hold the demoniac possession of inspired persons, of madmen, and of the sick, which has led to what may be called a diabolic pathology. The general conception of the world as a living animal, with all the tendencies ascribed to it by Plato, is only the primeval fact of the animation and personification of phenomena applied to the general idea of the universe. Hence it is easy to see how much of Plato's physics and psychology are due to the necessary and historic course of myth, and to the schools into which myth had been modified before his time.

We must dwell more particularly on his theory of ideas, since in this the advance made by Plato in the evolution of myth really consists, and it marks a very definite stage which had and still has a powerful influence on subsequent and modern thought.

We have already shown how, by the logical power of thought, this phase in the ideal evolution of myth was reached, and we have traced it in an inchoate form in various rude peoples, as well as in its ultimate modification in Plato. In his writings it takes the form of a complete, vast, and organic theory. The logical conceptions and representative ideas, idols peculiar to the mind, which were at first involved in fetishtic and anthropomorphic images, are now divested of their earlier wrappings, and are classified as the intellectual ideas which they really are, and which they have become by the innate and reflex exercise of human thought. But on account of the faculty which ever governs our immediate perception of internal and external things they could not in Plato's time, nor indeed in that of many subsequent philosophers, remain as simple intellectual signs of the process of reason. This faculty influenced these conceptions, these psychical forms, whether particular, specific, or general, and they became living subjects, like phenomena, objects, shades, images in dreams, normal and abnormal hallucinations. Thus the Ideas in Plato became, reflectively and theoretically, entities with an intrinsic existence, eternal, divine, and absolute essences. But the fetish, the anthropomorphic idol, was not only regarded as a living but as a causative subject; the same power was likewise infused into the Ideas, and they were held to be causes of particular things, of which they were the earlier and eternal type. Thus the myth in the Platonic Ideas became scientific, but it continued to be a myth; the substance varied, but the form was the same. The objective phenomena of the world had first been personified, or their fanciful images were assumed to be objective; now the world of reason was personified, and mythology became intellectual instead of cosmic.

Those who opposed Plato's theory of ideas said that he realized abstractions, or personified ideas; but no one, as I think, perceived the natural process which led him to do so, nor explained the faculty by which he was necessarily influenced. Plato's theory was only an ultimate phase of the evolution of the vague and primitive animation of the world, which had passed through fetishism, polytheism, and the worship of the elements of nature, and had reached the entification and subjectivity of ideas, which was also attained by natural science, after passing through its mythical envelopment. We have noted the causes, which in the case of the earlier philosophers happened to be objective, while they were in Plato's case subjective, owing to the character and temperament of his mind; both conduced to the development and æsthetic splendour of this teaching among the Greeks. The teaching of Plato, which had more or less influence on all the earlier civilized peoples, of his own and subsequent times, and which was also involved in the mythical representations of later savages, assumed an aspect which varied with the special history, the ethnic temperament, the geographical and extrinsic conditions of different peoples; but considered in itself, it is always the same, and is the necessary result of the evolution of myth and of thought. Since the evolution of myth leads to the gradual genesis of science, which becomes more rational as myth is transformed from the material to the ideal, ideas are substituted for myths, and laws, as Vico well observes, for the canons of poetry.

This noble and more rational theory of eternal and causative Ideas resembles anthropomorphic polytheism in concentrating into one supreme Idea the intellectual Zeus, the Being of beings, according to another mythical and scientific representation by Aristotle, and it was afterwards combined with the Semitic idea of the Absolute. This was fused with the Logos, the Platonic demiurgos of Messianic ideas, and afterwards produced the universal philosophy and religion of Catholicism, which dominated and still dominates over thought with vigorous tenacity, and extends into all the civilized world inhabited by European races. We do not only trace the same thought, modified, classified, and perfected in the Fourth Gospel, in the Councils, the Fathers, and the schoolmen, but also in independent philosophies. In our own time it has assumed new forms, derived from the rapid progress made in cosmic and experimental sciences, even in those which are apparently the most rationalizing. It is manifest in Hegel, Fichte, and Schelling, nor is it difficult to trace it in the latest and artificial theories of the schools of Schopenhauer and Hartmann. In all these cases the entification of logical conceptions is evident; in all there is an arbitrary personification of a conception or of a fundamental Idea.

In order fully to understand the evolution of thought in myth and science, it is necessary to consider the other schools which arose in Greece, prior to, and contemporaneously with, Plato, as we shall thus obtain a more comprehensive idea of the course of such a development. In addition to the natural and partly ideal schools, the Ionic, the Eleatic, the Pythagorean and the Platonic, there arose those of Leucippus, Democritus, and Epicurus, which might be called mechanical, and that of Aristotle, which takes a middle course between the idea and the fact, between the dynamic and the mechanical explanation of the universe.

In an intellectual people like the Greeks there arose, in addition to the speculative theories already mentioned, other opinions which were derived from minds singularly free from mythical ideas; the world was considered as a concourse of independent atoms; its genesis thus became more conformable with abstract mathematical calculation, effected by this combination of simple bodies and the evolution of elements. This was what Leucippus, Democritus, and Epicurus undertook to teach, passing beyond the natural and ideal myths, in order to take their stand on the movement of isolated parts as the maker of the universe. Hence followed the theory of atoms, and the mechanical construction of the world, of bodies and souls, their continual composition and decomposition. Since, however, these were mere speculations, not supported by experimental methods and adequate instruments, mythical forms were confounded with the mechanical explanation of the world, such as the altogether anthropomorphic conception of gods who were dissolved and formed again; the sensible effluvium from images, an effluvium which revealed the ancient belief in the normal and abnormal personification of imaginary forms, and of ideas. Yet the character of this teaching was progressive and rational in comparison with the mythical and ideal theory of Plato, and with the schools and religions which emanated from him, even up to our time, and thought was strongly stimulated in its opposition to the continuance of myth.

The influence of this school was confirmed by the Aristotelian teaching; if on the one side Aristotle inclined towards the mythical entities of Plato, and the old zoomorphic conception of the world, on the other his theory of perception and of ideas, his amazing observations in physiology and anatomy, and his natural classification of the animal kingdom, induced a positive tendency of thought, an a posteriori method of observation, which awakened the intelligence and predisposed it to a more rational and scientific evolution. His geocentric ideas of cosmogony, his logical forms, the human architecture of the world, his conception of the Being who was the end and cause of motion in all things, were indeed obstinately maintained by the philosophy of Catholics and schoolmen, and served as an obstacle to the real progress of science; but on the other hand, his general method of observing nature, the discoveries which he made, and the tendency of his researches, as well as the importance he assigned to consciousness in the formation of ideas, did much to foster independent inquiry in the history of human thought; and coupled with the earlier mechanical schools, he prepared the way for the evolution of modern science. This is not the place for tracing the simultaneous course of the evolution of the ideal and mechanical schools during the ages which separate us from their origin; and while the influence of the one gradually waned, the other gained strength, although in a sporadic way, first among privileged minds, and then more generally.

It necessarily happened that as the evolution of thought went on, impelled by its early tendencies, both mechanical and positive, the ideal system was also modified, and gave place to sounder and truer theories. This great fact, the ultimate evolution of our own time, was effected on the one side by psychological analysis, and on the other by the direct and experimental observation of nature. Setting aside the gradual preparation which led up to this point, we can consider Descartes and Galileo as the representatives of these two great factors; since the one by the analysis of thought, the other by natural experiments, overthrew the mythical ideas, although without being aware that the achievement would produce such grand results.

The Platonic Ideas were objective to the mind, and independent of it, since they were regarded as a divine, concrete, absolute world in themselves. The earlier evolution of myth and science relied upon this and were resolved into it. But we know that the process of thought is continuous in historic races, and that myth is gradually divested of its personality and assumes a more intellectual form in the mind. Thus the material Idea passed into an intellectual conception; that which first appeared in an objective and extrinsic form became subjective and intrinsic, a transition which was effected by the nominalists. This gave rise to a cognition which was altogether psychological; at first reality was wholly objective, and the ideas were only a sublime intellectual myth, but now the objective world disappeared, and the intellect which formulated the conception was the only real thing. In virtue of the faculty of entification, only the mind and its ideas were real, the world and all which it contained had a doubtful existence. This tendency had its ultimate expression in Fichte, who created the universe by means of the Ego, thus transforming the earlier objective myth into one which was wonderfully subjective. Descartes doubted about everything beyond the range of his own thought, and was the first to overthrow the former ideal realism, and to lead the way to science, and to more rational analysis. To him the teaching of Spinoza and Kant was really due, as well as the English schools which had so much to do with the destruction of the earlier mythical edifice of ideas.
