righteous action. Thus, Lionardo Bruni[21] speaks of poetry as "so valuable an aid to knowledge, and so ennobling a source of pleasure"; and Æneas Sylvius Piccolomini, in his treatise De Liberorum Educatione (1450), declares that the crucial question is not, Is poetry to be contemned? but, How are the poets to be used? and he solves his own question by asserting that we are to welcome all that poets can render in praise of integrity and in condemnation of vice, and that all else is to be left unheeded.[22] Beyond this, the humanists urged in favor of poetry the fact of its antiquity and divine origin, and the further fact that it had been praised by great men of all professions, and its creators patronized by kings and emperors from time immemorial.

There were then at the end of the Middle Ages, and the beginning of the Renaissance, two opposing tendencies in regard to the poetic art, one representing the humanistic reverence for ancient culture, and for poetry as one of the phases of that culture, and the other representing not only the mediæval tradition, but a purism allied to that of early Christianity, and akin to the ascetic conceptions of life found in almost every period. These two tendencies are expressed specifically in their noblest forms by the great humanist Poliziano, and the great moral reformer Savonarola. In the Sylvæ, written toward the close of the fifteenth century, Poliziano dwells on the divine origin of poetry, as Boccaccio had done in his Vita di Dante; and then, after the manner of Horace, he describes its ennobling influence on man, and its general influence on the progress of civilization.[23] He then proceeds to survey the progress of poetry from the most ancient times, and in so doing may be said to have written the first modern history of literature. The second section of the Sylvæ discusses the bucolic poets; the third contains that glorification of Virgil which began during the Middle Ages, and, continued by Vida and others, became in Scaliger literary deification; and the last section is devoted to Homer, who is considered as the great teacher of wisdom, and the wisest of the ancients. Nowhere does Poliziano exhibit any appreciation of the æsthetic value of poetry, but his enthusiasm for the great poets, and indeed for all forms of ancient culture, is unmistakable, and combined with his immense erudition marks him as a representative poet of humanism.[24]

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 mediæval 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 æsthetic 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 coördinate 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.

III. The Final Justification of Poetry

The influence of Aristotle's Poetics in classical antiquity, so far as it is possible to judge, was very slight; there is no apparent reference to the Poetics in Horace, Cicero, or Quintilian,[27] and it was entirely lost sight of during the Middle Ages. Its modern transmission was due almost exclusively to Orientals.[28] The first Oriental version of Aristotle's treatise appears to have been that made by Abu-Baschar, a Nestorian Christian, from the Syriac into Arabic, about the year 935. Two centuries later, the Moslem philosopher Averroës made an abridged version of the Poetics, which was translated into Latin in the thirteenth century, by a certain German, named Hermann, and again, by Mantinus of Tortosa in Spain, in the fourteenth century. Hermann's version seems to have circulated considerably in the Middle Ages, but it had no traceable influence on critical literature whatsoever. It is mentioned and censured by Roger Bacon, but the Poetics in any form was probably unknown to Dante, to Boccaccio, and beyond a single obscure reference, to Petrarch. There is no question that for
