This rationalization of the Renaissance rules of poetry was effected by contemporary philosophy; if not by the works and doctrines of Descartes himself, at least by the general tendency of the human mind at this period, of which these works and doctrines are the most perfect expressions. Boileau's _Art Poetique_ has been aptly called the _Discours de la Methode_ of French poetry. So that while the contribution of Malherbe and his school to classicism lay in the insistence on clearness, propriety, and verbal and metrical perfection, and the contribution of the Italian Renaissance lay in the infusion of respect for classical antiquity and the imposition of a certain body of fixed rules, the contribution of contemporary philosophy lay in the rationalization or universalization of these rules, and in the imposition of an abstract and absolute standard of taste. But Cartesianism brought with it certain important limitations and deficiencies. Boileau himself is reported to have said that "the philosophy of Descartes has cut the throat of poetry;"[436] and there can be no doubt that this is the exaggerated expression of a certain inevitable truth. The excessive insistence on the reason brought with it a corresponding undervaluation of the imagination. The rational and rigidly scientific basis of Cartesianism was forced on classicism; and reality became its supreme object and its final test:-- "Rien n'est beau que le vrai." Reference has already been made to various disadvantages imposed on classicism by the very nature of its origin and growth; but the most vital of all these disadvantages was the influence of the Cartesian philosophy or philosophic temper. With the scientific basis thus imposed on literature, its only safeguard against extinction was the vast influence of a certain body of fixed rules, which literature dared not deviate from, and which it attempted to justify on the wider grounds of philosophy. These rules, then, the contribution of Italy, saved poetry in France from extinction during the classical period; and of this a remarkable confirmation is to be found in the fact that not until the rationalism of the seventeenth and eighteenth centuries was superseded in France, did French literature rid itself of this body of Renaissance rules. Cartesianism, or at least the rationalistic spirit, humanized these rules, and imposed them on the rest of Europe. But though quintessentialized, they remained artificial, and circumscribed the workings of the French imagination for over a century. FOOT-NOTES: [417] Sedano, _Parnaso Espanol_, viii. 61.
