Only by this overthrow of ecclesiastical authority was rendered possible that unchecked freedom of intellectual inquiry which has been the great positive factor in modern advance. Step by step men have learned to know the condition, the history, the natural laws of the material world in which they live and the social world of which they are a part. The bearing of this growing knowledge on the conception of the spiritual life has been various,—seeming for a while to lie wholly apart from it; then at times menacing its existence or contracting its scope; again arming it with powerful weapons and enlarging its ideals. Of the latest chapters in the story of science, one has retold the origin of Christianity, divested it of miracle and revelation, and translated it into purely natural and human terms. Another chapter has fixed the general trend of the universe known to man as an ever advancing and broadening movement, under the name of Evolution.

Amid all these changes the Christian church has continued to present its ideals, precepts, incitements; partly affirming them in contradiction of all denial, partly adapting them to the changes of time and thought. The moral and spiritual interpretation of life has not been confined to the church, but has been voiced in each generation by poets, moralists, reformers, statesmen, each after his thought. Out of the conflict and confusion a substantial agreement and harmonious ideal is at last appearing. More clearly and confidently in our day than ever before the universe may be seen and felt by man as a Cosmos,—a beautiful order.

This bird's-eye view will grow more distinct and vivid if we study certain typical figures which group themselves as the representatives of succeeding generations. Our conventional division of centuries will serve as a convenient framework for four groups.

In the sixteenth century we have Sir Thomas More, uniting the highest virtue of the church with the clearest intelligence of the new thought, and setting forth in Utopia the ideal to be sought,—not mere individual salvation, not an ecclesiastical fold, but a human commonwealth of free, happy, and virtuous citizens.

Instead of the peaceful growth of such a society,—made impossible by selfishness, ignorance, and passion,—comes social upheaval and religious revolution, its central figure the burly, heroic, great-hearted Luther; by turns a rebel and a conservative; leading the successful revolt of Teutonic Europe against Rome, but leaving reconstruction to other hands.

Then we have Calvin, the builder of the creed of Protestantism; in its substance little but a symmetrical statement of mediaeval ideas, but resting its appeal not on authority, but logic; or, more exactly, on the authority of a book, which, having no longer an infallible interpreter, must be judged by human reason as to its contents and at last as to its nature and origin. Thus, unconsciously, Calvin initiated a religious democracy and ultimately a religion of reason; while for the time he established a creed more austere and grim than the Catholic. Opposite him stands Loyola, the reviver of Catholicism, infusing it with a new heroism and self-sacrifice; reaffirming and intensifying its authority; scornful of speculation, powerful in organization; zealot, missionary, educator; giving to ecclesiastical obedience an added emphasis, to organization a new force.

For a typical group in the next century, let us take Francis Bacon, leading the human intellect away from abstractions and from other worlds to the close, intelligent study of the material world in which men live. Beside him stands Shakspere, reading the world of humanity with eyes neither biased by creed nor sublimed by faith; portraying with marvelous range the joys, sorrows, humors of mankind; showing on his impartial canvas a true humanity, far different from the fictitious saint and fictitious sinner of the theologian; showing, as with the truth of nature, "virtue in her shape how lovely;" but with no consolation beside the grave, no satisfying ideal for man's pursuit nor rule for man's guidance. Near him we see "the Shakspere of divines," Jeremy Taylor; he, too, is close to the realities of life, but he is planted firm on the belief in a supernatural revelation of God, Christ, and a hereafter, and for those who so believe offers a simple, noble way of "Holy Living and Dying."

In Cromwell is embodied the attempt of extreme Protestantism to mould society and the state by the authority of a supernatural religion. The Puritan creed for which he stands is a mixture of Hebraic and Calvinistic elements; the Puritan temper is at its best heroic and austere, made despotic by its confidence of divine authority, and by its supernaturalism made indifferent to the new science and to the various elements of human nature on which statesmanship must build. Its political sway is brief, its effects on English and American character are lasting.

In the next century the master minds stand outside of Christianity. Voltaire assails the whole ecclesiastical and supernatural fabric with terrible weapons of hard sense and derision. For the target of his arrows he has a church at once corrupt, tyrannical, and weak, and a creed which the best intelligence has outgrown. He heartily scouts the church, dogma, miracle; admits a vague Deity and a possible hereafter, but cares little for them; is fearless, jovial, generous,—a rollicking, comfortable, formidable apostle of negations.

Into the vacuum he creates comes Rousseau, and at his touch there well up again deep fountains of feeling, belief, desire. Rousseau, too, has left behind him the church and its dogmas; but he craves love, joy, action, and finds scope for them. He delights in nature's beauty, and it is the symbol to him of a God in whom there remains of the Christian Deity only the element of beneficence. He exhorts men to return to nature, but it is a somewhat unreal nature, a dream of primeval innocence and simplicity. He idealizes the family relation, and brings wisdom and gentleness to the training of the child. He lacks the Hebraic and Puritan stress on conscience; the mild benevolence of his Deity is somewhat remote from the ethical need of man and from the actual procedure or the universe; Rousseau himself is tainted with sensuality,—a diseased, suffering, pathetic nature, with "sweet strings jangled," worthy of pity and of gratitude.
