THE IDEA OF PROGRESS
I

The supposition that fish do not recognize the existence of water nor birds the existence of air often has been used to illustrate the insensitive unawareness of which we all are capable in the presence of some encompassing medium of our lives. The illustration aptly fits the minds of multitudes in this generation, who live, as we all do, in the atmosphere of progressive hopes and yet are not intelligently aware of it nor conscious of its newness, its strangeness and its penetrating influence. We read as a matter of course such characteristic lines as these from Tennyson:

"Yet I doubt not thro' the ages one increasing purpose runs,
And the thoughts of men are widen'd with the process of the suns."

Such lines, however, are not to be taken as a matter of course; until comparatively recent generations such an idea as that never had dawned on anybody's mind, and the story of the achievement of that progressive interpretation of history is one of the most fascinating narratives in the long record of man's mental Odyssey. In particular, the Christian who desires to understand the influences, both intellectual and practical, which are playing with transforming power upon Christianity today, upon its doctrines, its purposes, its institutions, and its social applications, must first of all understand the idea of progress. For like a changed climate, which in time alters the fauna and flora of a continent beyond the power of human conservatism to resist, this progressive conception of life is affecting every thought and purpose of man, and no attempted segregation of religion from its influence is likely to succeed.

The significance of this judgment becomes the more clear when we note the fact that the idea of progress in our modern sense is not to be found before the sixteenth century. Men before that time had lived without progressive hopes just as before Copernicus they had lived upon a stationary earth. Man's life was not thought of as a growth; gradual change for the better was not supposed to be God's method with mankind; the future was not conceived in terms of possible progress; and man's estate on earth was not looked upon as capable of indefinite perfectibility. All these ideas, so familiar to us, were undreamed of in the ancient and medieval world. The new astronomy is not a more complete break from the old geocentric system with its stationary earth than is our modern progressive way of thinking from our fathers' static conception of human life and history.

It will be worth our while at the beginning of our study to review in outline this development of the idea of progress, that we may better understand the reasons for its emergence and may more truly estimate its revolutionary effects. In the ancient world the Greeks, with all their far-flung speculations, never hit upon the idea of progress. To be sure, clear intimations, scattered here and there in Greek literature, indicate faith that man in the past had improved his lot. Aeschylus saw men lifted from their hazardous lives in sunless caves by the intervention of Prometheus and his sacrificial teaching of the arts of peace; Euripides contrasted the primitive barbarism in which man began with the civilized estate which in Greece he had achieved—but this perceived advance never was erected into a progressive idea of human life as a whole. Rather, the original barbarism, from which the arts of civilization had for a little lifted men, was itself a degeneration from a previous ideal estate, and human history as a whole was a cyclic and repetitious story of never-ending rise and fall. Plato's philosophy of history was typical: the course of cosmic life is divided into cycles, each seventy-two thousand solar years in length; during the first half of each cycle, when creation newly comes from the hands of Deity, mankind's estate is happily ideal, but then decay begins and each cycle's latter half sinks from bad to worse until Deity once more must take a hand and make all things new again. Indeed, so far from reaching the idea of progress, the ancient Greeks at the very center of their thinking were incapacitated for such an achievement by their suspiciousness of change. They were artists and to them the perfect was finished, like the Parthenon, and therefore was incapable of being improved by change. Change, so far from meaning, as it does with us, the possibility of betterment, meant with them the certainty of decay; no changes upon earth in the long run were good; all change was the sure sign that the period of degeneration had set in from which only divine intervention could redeem mankind. Paul on Mars Hill quoted the Greek poet Aratus concerning the sonship of all mankind to God, but Aratus's philosophy of history is not so pleasantly quotable:

"How base a progeny sprang from golden sires!
And viler shall they be whom ye beget." [1]

Such, in general, was the non-progressive outlook of the ancient Greeks.
