FREEDOM OF THOUGHT

is that, in examining principles, the word just is misleading. All the virtues are based on experience, physiological or social, and justice is no exception. Just designates a class of rules or principles of which the social utility has been found by experience to be paramount and which are recognized to be so important as to override all considerations of immediate expediency. And social utility is the only test. It is futile, therefore, to say to a Government that it acts unjustly in coercing opinion, unless it is shown that freedom of opinion is a principle of such overmastering social utility as to render other considerations negligible. Socrates had a true instinct in taking the line that freedom is valuable to society.

The reasoned justification of liberty of thought is due to J. S. Mill, who set it forth in his work On Liberty, published in 1859. This book treats of liberty in general, and attempts to fix the frontier of the region in which individual freedom should be considered absolute and unassailable. The second chapter considers liberty of thought and discussion, and if many may think that Mill unduly minimized the functions of society, underrating its claims as against the individual, few will deny the justice of the chief arguments or question the general soundness of his conclusions.
