Murray Rothbard offers this challenging observation about socialism in his 1964 piece from Continuum, featured on LRC today:
The libertarian needs, perhaps most of all, to be informed by history, and to realize that conservatism was always the polar opposite of classical liberalism. Socialism, in contrast, was not the polar opposite of either, but rather, in my view, a muddled and irrationally contradictory mixture of both liberalism and conservatism. For socialism was essentially a movement to come to terms with the industrial revolution, to try to achieve liberal ends by the use of collectivistic, conservative means. It tried to achieve the ideals of peace, freedom, and a progressing standard of living by using the collectivist, organicist, hierarchical means of conservatism as adapted to industrial society.
As a middle-of-the-road doctrine, it is easy for socialism, once it abandoned the liberal ideals of peace and freedom, to shift completely to the conservative pole in the many varying forms of “national socialism.”
