To clear the ground for the new school of nature, truth and reason was Boileau's first task. It was a task which called for courage and skill. The public taste was still uncertain. Laboured and lifeless epics like Chapelain's _La Pucelle_, petty ingenuities in metre like those of Cotin, violence and over-emphasis, extravagances of sentiment, faded preciosities, inane pastoralisms, gross or vulgar burlesques, tragedies languorous and insipid, lyrics of pretended passion, affectations from the degenerate Italian literature, super-subtleties from Spain--these had still their votaries. And the conduct of life and characters of men of letters were often unworthy of the vocation they professed. "La haine d'un sot livre" was an inspiration for Boileau, as it afterwards was for our English satirist Pope; and he felt deeply that dignity of art is connected with dignity of character and rectitude of life--"Le vers se sent toujours des bassesses de coeur." He struck at the follies and affectations of the world of letters, and he struck with force: it was a needful duty, and one most effectively performed. Certain of the Epistles, which are written with less pitiless severity and with a more accomplished mastery of verse, continue the work of the Satires. From Horace he derived much, something from Juvenal, and something from his predecessor Regnier; but he had not the lightness nor the _bonhomie_ of Horace, nor his easy and amiable wisdom. In the _Art Poetique_ Boileau is constructive; he exhibits the true doctrine of literature, as he conceived it. Granted genius, fire, imagination--the gifts of heaven--what should be the self-imposed discipline of a poet? Above all, the cultivation of that power which distinguishes false from true, and aids every other faculty--the reason. "Nothing," declares Boileau, "is beautiful save what is true;" nature is the model, the aim and end of art; reason and good sense discern reality; they test the fidelity of the artistic imitation of nature; they alone can vouch for the correspondence of the idea with its object, and the adequacy of the expression to the idea. What is permanent and universal in literature lives by the aid of no fashion of the day, but by virtue of its truth to nature. And hence is derived the authority of the ancient classics, which have been tried by time and have endured; these we do not accept as tyrants, but we may safely follow as guides.
