Again, that sublime task which Vico declared proper to poetry, the task of giving life to inanimate objects, belongs properly not to poetry but to myth. Mythology, embodying its concepts in images, which are always individual things, at last animates them like living beings. Thus primitive man, ignorant of the cause of lightning and therefore not possessing the scientific definition of it, was led by the mythological tendency to conceive the sky as a vast living being, who, like man himself when, in the grip of his fierce passions, he shouted, muttered or roared, spoke and meant something by his speech. It is mythology again, not poetry, whose origin must be traced to "poverty," to the weakness of men's minds and their inability to deal with the problems they would solve, in their incapacity for thinking in rational universals and expressing themselves in accurate language, whence arose imaginative universals and metonymy, synecdoche and metaphor of all kinds. The contradictions we have seen in the imaginative universal which make it incapable of acting as the foundation of an aesthetic doctrine are quite in keeping in the doctrine of myth: for myth consists precisely of these contradictions: it is a concept trying to be an image and an image trying to be a concept, and hence a kind of poverty, or even of powerful impotence,--a contrast, a mental transition where white no longer exists and black has not yet come into being. Finally, poetic wisdom, that is, the theology, science, cosmography, geography, astronomy and the whole system of other ideas and beliefs of primitive nations as Vico describes them, was really mythology, not, as he says, poetry, for the good reason, given by himself, that these things were their history: and poetry is poetry and not history, even more or less imaginary history. The Homeric poems are poetry in so far as they express the aspirations of Hellenism: the same poems, in so far as they were recited and heard as accounts of actual facts, are history: the two things being forms of mental products which, though they seem to be materially united in a single work, are not for that reason to be identified.
