His statement of the difference between poetry and history is a trifle less clear. He explains why to Aristotle poetry seemed more philosophical than history, and at the same time he refutes Aristotle's error that poetry deals with the universal, history with the particular. Poetry equals science, not because it is occupied with the intellectual concept, but because, like science, it is ideal. A good poetical fable must be all ideal: "With the idea the poet gives their being to things which are without it. Poetry is all fantastic, as being the art of painting the idea, not icastic, like the art of painting portraits. That is why poets, like painters, are called divine, because in that respect they resemble God the Creator." Vico ends by identifying poetry and history. The difference between them is posterior and accidental. "But, as it is impossible to impart false ideas, because the false consists of a vicious combination of ideas, so it is impossible to impart a tradition, which, though it be false, has not at first contained some element of truth. Thus mythology appears for the first time, not as the invention of an individual, but as the spontaneous vision of the truth as it appears to primitive man." Poetry and language are for Vico substantially identical. He finds in the origins of poetry the origins of languages and letters. He believed that the first languages consisted in mute acts or acts accompanied by bodies which had natural relations to the ideas that it was desired to signify. With great cleverness he compared these pictured languages to heraldic arms and devices, and to hieroglyphs. He observed that during the barbarism of the Middle Age, the mute language of signs must return, and we find it in the heraldry and blazonry of that epoch. Hence come three kinds of languages: divine silent languages, heroic emblematic languages, and speech languages. Formal logic could never satisfy a man with such revolutionary ideas upon poetry and language. He describes the Aristotelian syllogism as a method which explains universals In their particulars, rather than unites particulars to obtain universals, looks upon Zeno and the sorites as a means of subtilizing rather than sharpening the intelligence, and concludes that Bacon is a great philosopher, when he advocates and illustrates _induction_, "which has been followed by the English to the great advantage of experimental philosophy." Hence he proceeds to criticize mathematics, which, had hitherto always been looked upon as the type of the _perfect science_.
