Socialism may be worthless as a scheme, but it is not meaningless as a symptom. Rousseau's theory of the origin of society, of the social contract, and of a cure for all the social evils by a return to a state of nature, had, as we all know now, no more relation to fact than the dreams of an illiterate drunkard; but they were not without value as a vague and symbolical expression of certain evils from which the France of his day was suffering.
