Dante is an embodiment of mediaeval belief in its most sublime and intense phase. He has much of the temper of the Hebrew psalmist, in his tremendous love and hate, his patriotism, his sorrow, his quest for the highest. This vast spiritual passion finds its expression and satisfaction in an invisible world, which promises in a future existence the supreme triumph and reign of a divine justice, wrath, and pity, and for which the visible world is but antechamber and probation. Dante shows the culmination of supernatural Christianity, but he has something further. The guide of his pilgrimage, the star of his hope, the inspiration of his life, is a woman,—loved with sublimation and tenderness, loved better after her death, and felt as the living link between the seen and unseen worlds. Thus at the heart of the old supernaturalism is the germ of a new conception, in which human love sanctified by death becomes the revealer.
In Dante we feel that the projection of human interest to an unseen and future world has reached its furthest limit. The mind of man must needs revert to some nearer home and sphere. And closely following Dante we see in England a group of figures who betoken the return. There is Chaucer, displaying the various energy and joy and humor of earthly life. There is Piers Plowman, showing the grim obverse of the medal, the hardship and woe of the poor. Wyclif insists on a personal religion, whose austere edge turns against ecclesiastical pretense and social wrong; and he applies reason so daringly that it cuts at the very centre of the church's dogma, in denying Transubstantiation. A little earlier we see Roger Bacon making a fresh beginning in the experimental philosophy which had been slighted for centuries. These four are the precursors respectively of the purely human view, as in Shakspere, of the elevation of the poor, of Protestantism, and of natural science.
As pagan mythology, Stoicism, and Judaism all were superseded by early Christianity, as that in turn was succeeded by mediaeval Catholicism, so another stage has brought us to the religion of to-day. The leading features of this last transition may be summarily sketched, we may then glance at certain groups of figures illustrating the advance in its successive periods, and so we shall come to the ideal of the present.
The religious transition of the last four centuries is in one aspect marked by the waning of authority and the growth of individual freedom; and in another aspect it is the substitution for a supernatural of a natural conception, or, we may say, in place of a divided and warring universe, a harmonious universe.
In this double progress toward individual liberty and toward a new way of thought, a conspicuous agency has been the advance of knowledge. Connected with the advance of knowledge has been an improvement of the actual conditions of human life. Meantime the ethical sense and the spiritual aspiration of mankind have asserted themselves, sometimes as slow-working, permanent forces, sometimes in revolutionary upheaval. With change both of material condition and of ways of thought, new forms of sentiment and aspiration have appeared,—a wider and tenderer humanity; a reverence for the order of nature and dependence upon the study of that order for human progress; a consciousness of the sublimity and beauty of nature as a divine revelation; a reliance upon the powers and intuitions of the human spirit as its only and sufficient guides; a rediscovery under natural and universal forms of the faith and hope which were once supposed inseparably bound up with ritual, dogma, and miracle, but which now when given freer wing find firmer support and loftier scope.
Along with these forces has gone the steady push of human nature for enjoyment, for ease, for power; the grasp of man for all he can get of whatever seems to him the highest good. There have been mutual injuries, degradations, retrogressions, such as darken all the pages of human history; the manifest evil which often defies all interpretation, and which only a profound faith can regard as "good in the making."
Together with these influences we must also reckon the special action of strong personalities.
No sharp line can be drawn between these various powers,—their interplay is constant. The main argument of the drama, from the mediaeval to the present phase, may be briefly shown.
Into the world as Dante knew it came Knowledge on three great lines,—opening the material universe, rediscovering a lost interpretation of life, and diffusing the secrets of the few among the many. The astronomers, voyagers, and geographers found out a new heaven and a new earth. The revival of Greek literature gave to the cultivated class a "renaissance," a rebirth, of speculative thought, of intellectual beauty, of delight in human activities for their own sake. It was a new birth in some of the old pagan sensuality, skeptical of heaven or hell; worse than the old sensuality because it trampled down the finer purity which Christianity had bred. In others it was a new birth to the pursuit of moral and social good, inspired by the master spirits of Judaism and early Christianity. Then came the invention of printing, and the aristocracy of intelligence widened rapidly toward democracy.
The foremost men of the new knowledge supported the Catholic church, either as a covert for indulgence or as a spiritual agency to be maintained and purified. The successful rebel against the church was a peasant-priest, who revolted because the moral unsoundness which long had sapped the hierarchy ran at last into open countenance of vice. It was originally a moral revolt, and it was led by a man who knew in his own experience that not only the ethical but the emotional life of the spirit was possible without dependence on the church of Rome. But neither Luther nor any of the reformers were men of spiritual originality. Driven to construct a new creed, they simply worked over the old dogmas, divesting them of the keys of priestly power—the Mass, the confessional, absolution, Purgatory, and the like; and giving infallible authority to the Bible only. A war of creeds followed, mingled with a strife of ambitions and a struggle between the powers of the secular state and of the hierarchy. To men of piety and peace like Erasmus and Melanchthon it seemed as if religion were only a loser by the long period of bloodshed and bitterness that followed. The gain, as we see it, was that half of Europe was wrested from the dominion of the Catholic church; that that church was driven to purify its morals; and that in the Protestant states the liberty which at first was only a change of masters spread gradually, as one sect after another established its foothold, and as the secular temper in the state rose above the ecclesiastical, until the religious freedom of the individual is at last becoming generally and securely established.
