On the other hand, the puristic conception of art is elaborated at great length by Savonarola in an apology for poetry contained in his tractate, _De Divisione ac Utilitate Omnium Scientarum_,[25] written about 1492. After classifying the sciences in true scholastic fashion, and arranging them according to their relative importance and their respective utility for Christianity, he attacks all learning as superfluous and dangerous, unless restricted to a chosen few. Poetry, according to the scholastic arrangement, is grouped with logic and grammar; and this mediaeval classification fixes Savonarola's conception of the theory of poetic art. He expressly says that he attacks the abuse of poetry and not poetry itself, but there can be no doubt that, at bottom, he was intolerant of creative literature. Like Plato, like moral reformers of all ages, he feared the free play of the imaginative faculty; and in connecting poetry with logic he was tending toward the elimination of the imagination in art. The basis of his aesthetic system, such as it is, rests wholly on that of Thomas Aquinas;[26] but he is in closer accord with Aristotle when he points out that versification, a merely conventional accompaniment of poetry, is not to be confounded with the essence of poetry itself. This distinction is urged to defend the Scriptures, which he regards as the highest and holiest form of poetry. For him poetry is coordinate with philosophy and with thought; but in his intolerance of poetry in its lower forms, he would follow Plato in banishing poets from an ideal state. The imitation of the ancient poets especially falls under his suspicion, and in an age given up to their worship he denies both their supremacy and their utility. In fine, as a reformer, he represents for us the religious reaction against the paganization of culture by the humanists. But the forces against him were too strong. Even the Christianization of culture effected during the next century by the Council of Trent was hardly more than temporary. Humanism, which represents the revival of ancient pagan culture, and rationalism, which represents the growth of the modern spirit in science and art, were currents too powerful to be impeded by any reformer, however great, and, when combined in classicism, were to reign supreme in literature for centuries to come. But Savonarola and Poliziano serve to indicate that modern literary criticism had not yet begun. For until some rational answer to the objections urged against poetry in antiquity and in the Middle Ages was forthcoming, literary criticism in any true sense was fundamentally impossible; and that answer came only with the recovery of Aristotle's _Poetics_.
