The students of natural phenomena early realized the arduous path they had to travel. They had to escape, above all things, from the past. They perceived that they could look for no help from those whose special business it was to philosophize and moralize in terms of the past. They had to look for light in their own way and in the directions from which they conjectured it might come. Their first object was, as Bacon put it, light, not fruit. They had to learn before they could undertake changes, and Descartes is very careful to say that philosophic doubt was not to be carried over to daily conduct. This should for the time being conform to accepted standards, unenlightened as they might be.
Such should be the frame of mind of one who seeks insight into human affairs. His subject matter is, however, far more intricate and unmanageable than that of the natural scientist. Experiment on which natural science has reared itself is by no means so readily applicable in studying mankind and its problems. The student of humanity has even more inveterate prejudices to overcome, more inherent and cultivated weaknesses of the mind to guard against, than the student of nature. Like the early scientists, he has a scholastic tradition to combat. He can look for little help from the universities as now constituted. The clergy, although less sensitive in regard to what they find in the Bible, are still stoutly opposed, on the whole, to any thoroughgoing criticism of the standards of morality to which they are accustomed. Few lawyers can view their profession with any considerable degree of detachment. Then there are the now all-potent business interests, backed by the politicians and in general supported by the ecclesiastical, legal, and educational classes. Many of the newspapers and magazines are under their influence, since they are become the business man's heralds and live off his bounty.
Business indeed has almost become our religion; it is defended by the civil government even as the later Roman emperors and the mediaeval princes protected the Church against attack. Socialists and communists are the Waldensians and Albigensians of our day, heretics to be cast out, suppressed, and deported to Russia, if not directly to hell as of old.
The Secret Service seems inclined to play the part of a modern Inquisition, which protects our new religion. Collected in its innumerable files is the evidence in regard to suspected heretics who have dared impugn "business as usual", or who have dwelt too lovingly on peace and good will among nations. Books and pamphlets, although no longer burned by the common hangman, are forbidden the mails by somewhat undiscerning officials. We have a pious vocabulary of high resentment and noble condemnation, even as they had in the Middle Ages, and part of it is genuine, if unintelligent, as it was then.
Such are some of the obstacles which the student of human affairs must surmount. Yet we may hope that it will become increasingly clear that the repression of criticism (even if such criticism becomes fault-finding and takes the form of a denunciation of existing habits and institutions) is inexpedient and inappropriate to the situation in which the world finds itself. Let us assume that such people as really advocate lawlessness and disorder should be carefully watched and checked if they promise to be a cause of violence and destruction. But is it not possible to distinguish between them and those who question and even arraign with some degree of heat the standardized unfairness and maladjustments of our times?
And there is another class who cannot by any exaggeration be considered agitators, who have by taking thought come to see that our conditions have so altered in the past hundred years and our knowledge so increased that the older ways of doing and viewing things are not only unreasonable, but actually dangerous. But so greatly has the hysteria of war unsettled the public mind that even this latter class is subject to discreditable accusations and some degree of interference.
We constantly hear it charged that this or that individual or group advocates the violent overthrow of government, is not loyal to the Constitution, or is openly or secretly working for the abolition of private property or the family, or, in general, is supposed to be eager to "overturn everything without having anything to put in its place".
The historical student may well recommend that we be on our guard against such accusations brought against groups and individuals. For the student of history finds that it has always been the custom to charge those who happened to be unpopular, with holding beliefs and doing things which they neither believed nor did. Socrates was executed for corrupting youth and infidelity to the gods; Jesus for proposing to overthrow the government; Luther was to the officials of his time one who taught "a loose, self-willed life, severed from all laws and wholly brutish".
Those who questioned the popular delusions in regard to witchcraft were declared by clergymen, professors, and judges of the seventeenth century to be as good as atheists, who shed doubt on the devil's existence in order to lead their godless lives without fear of future retribution. How is it possible, in view of this inveterate habit of mankind, to accept at its face value what the police or Department of Justice, or self-appointed investigators, choose to report of the teachings of people who are already condemned in their eyes?
Of course the criticism of accepted ideas is offensive and will long remain so. After all, talk and writing are forms of conduct, and, like all conduct, are inevitably disagreeable when they depart from the current standards of respectable behavior. To talk as if our established notions of religion, morality, and property, our ideas of stealing and killing, were defective and in need of revision, is indeed more shocking than to violate the current rules of action. For we are accustomed to actual crimes, misdemeanors, and sins, which are happening all the time, but we will not tolerate any suspected attempt to palliate them in theory.
