"Poetry, though one delve ever so little into his own self, interrogate his own soul, recall his memories of enthusiasms, has no other end than itself; it cannot have any other aim, and no poem will be so great, so noble, so truly worthy of the name of poem, as that which shall have been written solely for the pleasure of writing a poem. I do not wish to say that poetry should not ennoble manners--that its final result should not be to raise man above vulgar interests. That would be an evident absurdity. I say that if the poet has pursued a moral end, he has diminished his poetic force, and it would not be imprudent to wager that his work would be bad. Poetry cannot, under penalty of death or forfeiture, assimilate itself to science or morality. It has not Truth for object, it has only itself. Truth's modes of demonstration are different and elsewhere. Truth has nothing to do with ballads; all that constitutes the charm, the irresistible grace of a ballad, would strip Truth of its authority and power. Cold, calm, impassive, the demonstrative temperament rejects the diamonds and flowers of the muse; it is, therefore, the absolute inverse of the poetic temperament. Pure Intellect aims at Truth, Taste shows us Beauty, and the Moral Sense teaches us Duty. It is true that the middle term has intimate connection with the two extremes, and only separates itself from Moral Sense by a difference so slight that Aristotle did not hesitate to class some of its delicate operations amongst the virtues. And accordingly what, above all, exasperates the man of taste is the spectacle of vice, is its deformity, its disproportions. Vice threatens the just and true, and revolts intellect and conscience; but as an outrage upon harmony, as dissonance, it would particularly wound certain poetic minds, and I do not think it would be scandal to consider all infractions of moral beauty as a species of sin against rhythm and universal prosody. "It is this admirable, this immortal instinct of the Beautiful which makes us consider the earth and its spectacle as a sketch, as a correspondent of Heaven. The insatiable thirst for all that is beyond that which life veils is the most living proof of our immortality. It is at once by poetry and across it, across and through music, that the soul gets a glimpse of the splendors that lie beyond the tomb. And when an exquisite poem causes tears to rise in the eye, these tears are not the proof of excessive enjoyment, but rather the testimony of a moved melancholy, of a postulation of the nerves, of a nature exiled in the imperfect, which wishes to take immediate possession, even on earth, of a revealed paradise.
