But unfortunately we have not developed an equally enlightened attitude toward the inquirers into the nature of human relations in politics or industry, or toward those who would apply the experimental method to the development and scientific reconstruction of industrial or political government. Terms like _trusts_, _the money power_, _trade unions_, _industrial autocracy_, _collective bargaining_, _socialism_, _bolshevism_, _private monopoly_, _public ownership_, stir all our ancient fears, resentments, and hates. Men may be unorthodox in the physical sciences; we are growing tolerant of unorthodoxy in religious opinion. But unorthodoxy in the realm of politics is still frowned upon. We still imprison men for their political and economic opinions when they challenge the finality of accepted institutions and especially when they advocate the fundamental reconstruction of accepted forms of political and economic government. Yet it is quite as true in the realm of human relations, as in that of the physical sciences, that the truth and the truth only can make us free. Human brotherhood can be achieved only through human understanding. It is a commonplace to say that the vigorous growth of democracy depends upon education. But much repetition has dulled the vital implications of the assertion. We tend to forget that a democracy that permits essential knowledge to be withheld from general circulation digs its own grave; that while men talk of emancipation and freedom, ignorance may forge chains for their enslavement. When any group within the community is permitted to treat facts essential to the development of right human relations as "trade secrets," education itself becomes stereotyped and sterile. Text-books and "lessons" become spiritually and intellectually empty, like the prayers which certain Eastern cults pin to wheels that spin idly in the wind. The authentic prophets of democracy have constantly striven to keep the channels of popular education free from the clogging muck of selfishness, superstition, and prejudice. They have had faith in the essential justice and ultimate wisdom of informed public opinion. Such men have appeared in government, among the coal owners, among the miners, who are the commoners of the coal industry.
