Prescinding from any attempt to discuss the occult phenomena evoked, observed and studied in our day or to treat of the matters involved in the supernatural in the books of the day, one may state as a fact that the whole tendency of present day literature is to show a yearning for light on a subject of fundamental importance to human nature. Far back in the history of the race Job gave voice to the spiritual problems that are today engaging the attention of the world. Some fifteen hundred years ago, St. Augustine proposed to himself the question which so generally concerns the twentieth century: "On what matter of all those things of which thou art ignorant, hast thou the greatest desire for enlightenment?" The great Bishop of Hippo becomes the spokesman of humanity when he answers his own question by proposing another: "Am I immortal or not?" (Soliloquia 2d). In the realms of literature no work of man has answered that question with greater vividness of imagery, intensity of concentration, beauty of description--all based in a large measure on the teachings of Christianity--than has Dante in his Divine Comedy. Devised as a love offering to the memory of his beloved Beatrice who in the work is symbolized as Heavenly Light on the things hidden from man, the poem leads the reader through the dark abyss of Hell, the patient abode of Purgatory, the glorious realm of Heaven as if the poet had seen Eternity in reality instead of in imagination. Not only the state and the conditions of the soul after death does he visualize with the precision of Euclid, but as a philosopher and a theologian he proposes for our instruction in the course of the journey many questions of dogmatic and speculative thought affecting the Hereafter. He believes himself called to be not simply a poet to entertain his readers, but a prophet and a preacher with burning fire to deliver a message for man's salvation. So he asks the help of Heaven: "O Supreme Light that so high upliftest Thyself from mortal conceptions, re-lend a little to my mind of what Thou didst appear and make my tongue so powerful that it may be able to leave one single spark of Thy glory, for the future people: for by returning to my memory and by sounding a little in these verses, more of Thy victory shall be conceived" (Par. XXXIII, 67).
