In the exposition of these truths in their various relations a multitude of topics of interest are touched upon, and a multitude of opinions expressed which exhibit the character of Dante's mind and the vast extent of the acquisitions by which his studies had enriched it. The intensity of his moral convictions and the firmness of his moral principles are no less striking in the discourse than the nobility of his genius and the breadth of his intellectual view. Limited and erroneous as are many of his scientific conceptions, there is little trace of superstition or bigotry in his opinions; and though his speculations rest on a false conception of the universe, the revolting dogmas of the common mediæval theology in respect to the human and the Divine nature find no place in them. The mingling of fancy with fact, the unsoundness of the premises from which conclusions are drawn, the errors in belief and in argument, do not affect the main object of his writing, and the 'Convito' may still be read with sympathy and with profit, as a treatise of moral doctrine by a man the loftiness of whose intelligence rose superior to the hampering limitations of his age.
In its general character and in its biographical revelations the 'Banquet' forms a connecting link between the 'New Life' and the 'Divine Comedy.' It is not possible to frame a complete reconciliation between all the statements of the 'Banquet' in respect to Dante's experience after the death of Beatrice, and the narrative of them in the 'New Life'; nor is it necessary, if we allow due place to the poetic and allegoric interpretation of events natural to Dante's genius. In the last part of the 'New Life' he tells of his infidelity to Beatrice in yielding himself to the attraction of a compassionate lady, in whose sight he found consolation. But the infidelity was of short duration, and, repenting it, he returned with renewed devotion to his only love. In the 'Convito' he tells us that the compassionate lady was no living person, but was the image of Philosophy, in whose teaching he had found comfort; and the poems which he then wrote and which had the form, and were in the terms of, poems of Love, were properly to be understood as addressed—not to any earthly lady, but—to the lady of the understanding, the most noble and beautiful Philosophy, the daughter of God. And as this image of Philosophy, as the fairest of women, whose eyes and whose smile reveal the joys of Paradise, gradually took clear form, it coalesced with the image of Beatrice herself, she who on earth had been the type to her lover of the beauty of eternal things, and who had revealed to him the Creator in his creature. But now having become one of the blessed in heaven, with a spiritual beauty transcending all earthly charm, she was no longer merely a type of heavenly things, but herself the guide to the knowledge of them, and the divinely commissioned revealer of the wisdom of God. She looking on the face of God reflected its light upon him who loved her. She was one with Divine Philosophy, and as such she appears, in living form, in the 'Divine Comedy,' and discloses to her lover the truth which is the native desire of the soul, and in the attainment of which is beatitude.
It is this conception which forms the bond of union between the 'New Life,' the 'Banquet,' and the 'Divine Comedy,' and not merely as literary compositions but as autobiographical records. Dante's life and his work are not to be regarded apart; they form a single whole, and they possess a dramatic development of unparalleled consistency and unity. The course of the events of his life shaped itself in accordance with an ideal of the imagination, and to this ideal his works correspond. His first writing, in his poems of love and in the story of the 'New Life,' forms as it were the first act of a drama which proceeds from act to act in its presentation of his life, with just proportion and due sequence, to its climax and final scene in the last words of the 'Divine Comedy.' It is as if Fate had foreordained the dramatic unity of his life and work, and impressing her decree upon his imagination, had made him her more or less conscious instrument in its fulfillment.
Had Dante written only his prose treatises and his minor poems, he would still have come down to us as the most commanding literary figure of the Middle Ages, the first modern with a true literary sense, the writer of love verses whose imagination was at once more delicate and more profound than that of any among the long train of his successors, save Shakespeare alone, and more free from sensual stain than that of Shakespeare; the poet of sweetest strain and fullest control of the resources of his art, the scholar of largest acquisition and of completest mastery over his acquisitions, and the moralist with higher ideals of conduct and more enlightened conceptions of duty than any other of the period to which he belonged. All this he would have been, and this would have secured for him a place among the immortals. But all this has but a comparatively small part in raising him to the station which he actually occupies, and in giving to him the influence which he still exerts. It was in the 'Divine Comedy' that his genius found its full expression, and it is to this supreme poem that all his other work serves as substructure.
The general scheme of this poem seems to have been early formed by him; and its actual composition was the main occupation of his years of exile, and must have been its main, one might say its sufficient, consolation. Never was a book of wider scope devised by man; and never was one more elaborate in detail, more varied in substance, or more complete in execution. It is unique in the consistency of its form with its spirit. It possesses such organic unity and proportion as to resemble a work of the creative spirit of Nature herself.
The motive which inspired Dante in the 'Divine Comedy' had its source in his sense of the wretchedness of man in this mortal life, owing to the false direction of his desires, through his ignorance and his misuse of his free will, the chief gift of God to him. The only means of rescue from this wretchedness was the exercise by man of his reason, enlightened by the divine grace, in the guidance of his life. To convince man of this truth, to bring home to him the conviction of the eternal consequences of his conduct in this world, to show him the path of salvation, was Dante's aim. As poet he had received a Divine commission to perform this work. To him the ten talents had been given, and it was for him to put them to the use for which they had been bestowed. It was a consecrated task to which both heaven and earth set their hand, and a loftier task was never undertaken. It was to be accomplished by expounding the design of God in the creation, by setting forth the material and moral order of the universe and the share of man in that order, and his consequent duty and destiny. This was not to be done in the form of abstract propositions addressed to the understanding, but in a poetic narrative which should appeal to the heart and arouse the imagination; a narrative in which human life should be portrayed as an unbroken spiritual existence, prefiguring in its mortal aspects and experience its immortal destiny. The poem was not to be a mere criticism of life, but a solution of its mystery, an explanation of its meaning, and a guide of its course.
To give force and effect to such a design the narrative must be one of personal experience, so conceived as to be a type of the universal experience of man. The poem was to be an allegory, and in making himself its protagonist Dante assumed a double part. He represents both the individual Dante, the actual man, and that man as the symbol of man in general. His description of his journey through Hell, Purgatory, and Paradise has a literal veracity; and under the letter is the allegory of the conduct and consequences of all human life. The literal meaning and the allegorical are the web and woof of the fabric, in which the separate incidents are interwoven, with twofold thread, in designs of infinite variety, complexity, and beauty.
In the journey through Hell, Dante represents himself as guided by Virgil, who has been sent to his aid on the perilous way by Beatrice, incited by the Holy Virgin herself, in her infinite compassion for one who has strayed from the true way in the dark forest of the world. Virgil is the type of the right reason, that reason whose guidance, if followed, leads man to the attainment of the moral virtues, by the practice of which sin may be avoided, but which by themselves are not enough for salvation. These were the virtues of the virtuous heathen, unenlightened by divine revelation. Through the world, of whose evil Hell is the type and fulfillment, reason is the sufficient guide and guard along the perilous paths which man must traverse, exposed to the assaults of sin, subject to temptation, and compelled to face the very Devil himself. And when at last, worn and wearied by long-continued effort, and repentant of his frequent errors, he has overcome temptation, and entered on a course of purification through suffering and penitence, whereby he may obtain forgiveness and struggle upward to the height of moral virtue, reason still suffices to lead him on the difficult ascent, until he reaches the security and the joy of having overcome the world. But now reason no longer is sufficient. Another guide is needed to lead the soul through heavenly paths to the attainment of the divine virtues of faith, hope, and charity, by which the soul is made fit for Paradise. And here Beatrice, the type of theology, or knowledge of the things of God, takes the place of Virgil, and conducts the purified and redeemed soul on its return to its divine source, to the consummation of its desires and its bliss in the vision of God himself.
Such is the general scheme of the poem, in which the order of the universe is displayed and the life of man depicted, in scenes of immense dramatic variety and of unsurpassed imaginative reality. It embraces the whole field of human experience. Nature, art, the past, the present, learning, philosophy, all contribute to it. The mastery of the poet over all material which can serve him is complete; the force of his controlling imagination corresponds with the depth and intensity of his moral purpose. And herein lies the exceptional character of the poem, as at once a work of art of supreme beauty and a work of didactic morals of supreme significance. Art indeed cannot, if it would, divorce itself from morals. Into every work of art, whether the artist intend it or not, enters a moral element. But in art, beauty does not submit to be subordinated to any other end, and it is the marvel in Dante that while his main intent is didactic, he attains it by a means of art so perfect that only in a few rare passages does beauty fall a sacrifice to doctrine. The 'Divine Comedy' is indeed not less incomparable in its beauty than in its vast compass, the variety of its interest, and in the harmony of its form with its spirit. In his lectures 'On Translating Homer' Mr. Arnold, speaking of the metre of 'Paradise Lost,' says:—"To this metre, as used in the 'Paradise Lost,' our country owes the glory of having produced one of the only two poetical works in the grand style which are to be found in the modern languages; the 'Divine Comedy' of Dante is the other." But Mr. Arnold does not point out the extraordinary fact, in regard to the style of the 'Divine Comedy,' that this poem stands at the beginning of modern literature, that there was no previous modern standard of style, that the language was molded and the verse invented by Dante; that he did not borrow his style from the ancients, and that when he says to Virgil, "Thou art he from whom I took the fair style that has done me honor," he meant only that he had learned from him the principles of noble and adequate poetic expression. The style of the 'Divine Comedy' is as different from that of the Æneid as it is from that of 'Paradise Lost.'
There are few other works of man, perhaps there is no other, which afford such evidence as the 'Divine Comedy' of uninterrupted consistency of purpose, of sustained vigor of imagination, and of steady force of character controlling alike the vagaries of the poetic temperament, the wavering of human purpose, the fluctuation of human powers, and the untowardness of circumstance. From beginning to end of this work of many years there is no flagging of energy, no indication of weakness. The shoulders, burdened by a task almost too great for mortal strength, never tremble under their load.
