“They are men and women who tend to believe that the human being is perfectible and social progress predictable, and that the instrument for effecting the two is reason; that truths are transitory and empirically determined; that equality is desirable and attainable through the action of state power; that social and individual differences, if they are not rational, are objectionable, and should be scientifically eliminated; that all people and societies strive to organize themselves upon a rationalist and scientific paradigm.”

Communalism (1974)
Context: Prior to 1918 the word “communism” did not mean Left Social Democracy of the sort represented by the Russian Bolsheviks, a radical, revolutionary form of State socialism. Quite the contrary, it was used of those who wished in one way or another to abolish the State, who believed that socialism was not a matter of seizing power, but of doing away with power and returning society to an organic community of non-coercive human relations. They believed that this was what society was naturally, and that the State was only a morbid growth on the normal body of oeconomia, the housekeeping of the human family, grouped in voluntary association. Even the word “socialism” itself was originally applied to the free communist communities which were so common in America in the nineteenth century.
