I have devoted a chapter to the poetry of the most poetical nation, the Arabs; their poets produced the anomaly of utilizing the most artificial metres, and yet never lost sight of the fact that ecstasy was the very life of the poem. Probably no poets in the world have produced such exquisite love poetry as the Arabs; they have also had great influence on modern European poetry, for it is being recognized that modern romantic fiction, especially in its employment of the tenderness of the love sentiment as a frequent theme, was transplanted from them.
Poetry is the soul of literature, and we should cease limiting the term to rhythmical or patterned productions, and apply it to emotional writing in general. No term for the word poet in any language that I am acquainted with includes in its etymological significance the idea of rhythm or metrical pattern. The Hebrew word for poet is one who utters prophecies or parables; the Greek word signifies a "maker"; the Latin word "seer," the Arabian word "one who knows." Critics of the Bible have especially recognized that the chief characteristic of both the true and the false prophet (Nabi) was the ecstatic state; the Bible itself is of course authority for this fact. The inferior prophet was one, however, in whom the ecstatic state was hypnotically produced, in whom the rational and moral faculties were suspended; the great prophets were those in whom a powerful sense of social justice was illuminated by the ecstatic state; hence the prophecies of the Bible are not orations wherein rhetoric is a factor, but genuine literature of ecstasy, or poetry in rhythmical prose, using parallelism.
I need not continue to give analyses of the Greek "poetes," the Latin "vates," or the Arabian "shair," for it has been usually conceded that these words all refer in their primary significance to the imaginative work, or ecstatic state of the author, and not to the mere dabbler in verse forms.
With theories of poetry being a product of the unconscious, as developed by Freud and his disciples, or as being expression as advanced by Croce, my task does not become so utterly devoid of reason as may appear at first sight. One must not forget that the critics of poetry have formed their conceptions of poetry by deducing rules from the verse poems of the world's literature. Instead of looking ahead, they have always looked back. Whenever a new great poet appeared, like Wordsworth, Whitman or Ibsen for instance, they had to modify their theories, and to revise their books on poetics and rhetoric. If the productions of Homer and Æschylus had been entirely different, we no doubt would have had other conceptions of poetry prevailing. Yet it is only by mere accident that Homer dealt with gods, wars, mythical events and employed dactylic hexameter. It is again also by pure chance that Æschylus used various metres, made Prometheus and the Furies living beings, was sponsor for a philosophy of divine punishment and often indulged in artificial diction. Had these poets written novels instead, conveying just as much genius and ecstasy as they did in their verse works, the critics of poetry would have deduced an entirely different conception of it.
