In time the wickedness became such on the newly created earth that God resolved to blot out mankind, excepting only Noah's family, which was spared to repeople the earth after the Flood, but the unity of language that man had formerly possessed was lost. At the appointed time, preceded by many prophetic visions among the chosen people, God sent his Son to live the life of men on earth and become their Saviour by submitting to death. Thereafter, with the spread of the gospel, the struggle between the kingdom of God and that of the devil became the supreme conflict of history. It was to culminate in the Last Judgment, when the final separation of good and evil should take place and the blessed should ascend into the heavens to dwell with God forever, while the wicked sank to hell to writhe in endless torment.
This general account of man, his origin and fate, embraced in the Christian Epic, was notable for its precision, its divine authenticity, and the obstacles which its authority consequently presented to any revision in the light of increasing knowledge. The fundamental truths in regard to man were assumed to be established once and for all. The Greek thinkers had had little in the way of authority on which to build, and no inconsiderable number of them frankly confessed that they did not believe that such a thing could exist for the thoroughly sophisticated intelligence. But mediaeval philosophy and science were grounded wholly in authority. The mediaeval schoolmen turned aside from the hard path of skepticism, long searchings and investigation of actual phenomena, and confidently believed that they could find truth by the easy way of revelation and the elaboration of unquestioned dogmas.
This reliance on authority is a fundamental primitive trait. We have inherited it not only from our mediaeval forefathers, but, like them and through them, from long generations of prehistoric men. We all have a natural tendency to rely upon established beliefs and fixed institutions. This is an expression of our spontaneous confidence in everything that comes to us in an unquestioned form. As children we are subject to authority and cannot escape the control of existing opinion. We unconsciously absorb our ideas and views from the group in which we happen to live. What we see about us, what we are told, and what we read has to be received at its face value so long as there are no conflicts to arouse skepticism.
We are tremendously suggestible. Our mechanism is much better adapted to credulity than to questioning. All of us believe nearly all the time. Few doubt, and only now and then. The past exercises an almost irresistible fascination over us. As children we learn to look up to the old, and when we grow up we do not permit our poignant realization of elderly incapacity among our contemporaries to rouse suspicions of Moses, Isaiah, Confucius, or Aristotle. Their sayings come to us unquestioned; their remoteness makes inquiry into their competence impossible. We readily assume that they had sources of information and wisdom superior to the prophets of our own day.
During the Middle Ages reverence for authority, and for that particular form of authority which we may call the tyranny of the past, was dominant, but probably not more so than it had been in other societies and ages—in ancient Egypt, in China and India. Of the great sources of mediaeval authority, the Bible and the Church Fathers, the Roman and Church law, and the encyclopaedic writings of Aristotle, none continues nowadays to hold us in its old grip. Even the Bible, although nominally unquestioned among Roman Catholics and all the more orthodox Protestant sects, is rarely appealed to, as of old, in parliamentary debate or in discussions of social and economic questions. It is still a religious authority, but it no longer forms the basis of secular decisions.
The findings of modern science have shaken the hold of the sources of mediaeval authority, but they have done little as yet to loosen our inveterate habit of relying on the more insidious authority of current practice and belief. We still assume that received dogmas represent the secure conclusions of mankind, and that current institutions represent the approved results of much experiment in the past, which it would be worse than futile to repeat. One solemn remembrancer will cite as a warning the discreditable experience of the Greek cities in democracy; another, how the decline of "morality" and the disintegration of the family heralded the fall of Rome; another, the constant menace of mob rule as exemplified in the Reign of Terror. But to the student of history these alleged illustrations have little bearing on present conditions. He is struck, moreover, with the ease with which ancient misapprehensions are transmitted from generation to generation and with the difficulty of launching a newer and clearer and truer idea of anything. Bacon warns us that the multitude, "or the wisest for the multitude's sake", is in reality "ready to give passage rather to that which is popular and superficial than to that which is substantial and profound; for the truth is that time seemeth to be of the nature of a river or stream, which carrieth down to us that which is light and blown up, and sinketh and drowneth that which is weighty and solid".
It is very painful to most minds to admit that the past does not furnish us with reliable, permanent standards of conduct and of public policy. We resent the imputation that things are not going, on the whole, pretty well, and find excuses for turning our backs on disconcerting and puzzling facts. We are full of respectable fears and a general timidity in the face of conditions which we vaguely feel are escaping control in spite of our best efforts to prevent any thoroughgoing readjustment. We instinctively try to show that Mr. Keynes must surely be wrong about the Treaty of Versailles; that Mr. Gibbs must be perversely exaggerating the horrors of modern war; that Mr. Hobson certainly views the industrial crisis with unjustifiable pessimism; that "business as usual" cannot be that socially perverse and incredibly inexpedient thing Mr. Veblen shows it to be; that Mr. Robin's picture of Lenin can only be explained by a disguised sympathy for Bolshevism.
Yet, even if we could assume that traditional opinion is a fairly clear and reliable reflection of hard-earned experience, surely it should have less weight in our day and generation than in the past. For changes have overtaken mankind which have fundamentally altered the conditions in which we live, and which are revolutionizing the relations between individuals and classes and nations. Moreover, we must remember that knowledge has widened and deepened, so that, could any of us really catch up with the information of our own time, he would have little temptation to indulge the mediaeval habit of appealing to the authority of the past.
The Christian Epic did not have to rely for its perpetuation either on its intellectual plausibility or its traditional authority. During the Middle Ages there developed a vast and powerful religious State, the mediaeval Church, the real successor, as Hobbes pointed out, to the Roman Empire; and the Church with all its resources, including its control over "the secular arm" of kings and princes, was ready to defend the Christian beliefs against question and revision. To doubt the teachings of the Church was the supreme crime; it was treason against God himself, in comparison with which—to judge from mediaeval experts on heresy—murder was a minor offense.
We do not, however, inherit our present disposition to intolerance solely from the Middle Ages. As animals and children and savages, we are naively and unquestioningly intolerant. All divergence from the customary is suspicious and repugnant. It seems perverse, and readily suggests evil intentions. Indeed, so natural and spontaneous is intolerance that the question of freedom of speech and writing scarcely became a real issue before the seventeenth century. We have seen that some of the Greek thinkers were banished, or even executed, for their new ideas. The Roman officials, as well as the populace, pestered the early Christians, not so much for the substance of their views as because they were puritanical, refused the routine reverence to the gods, and prophesied the downfall of the State.
