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. It is inevitable that new views should appear to the thoughtless to be justifications or extenuations of evil actions and an encouragement of violence and rebellion, and that they will accordingly be bitterly denounced. But there is no reason why an increase of intelligence should not put a growing number of us on our guard against this ancient pitfall.
