Ludwig von Mises on Karl Marx

“All the sophisticated syllogisms of the ponderous volumes published by Marx, Engels, and hundreds of Marxian authors cannot conceal the fact that the only and ultimate source of Marx's prophecy is an alleged inspiration by virtue of which Marx claims to have guessed the plans of the mysterious powers determining the course of history. Like Hegel, Marx was a prophet communicating to the people the revelation that an inner voice had imparted to him.”

“On the one hand, Karl Marx wrote of the inevitability of socialism. But on the other hand, he organized a socialist movement, a socialist party, declared again and again that his socialism was revolutionary, and that the violent overthrow of the government was necessary to bring about socialism.”

“Marx's economic teachings are essentially a garbled rehash of the theories of Adam Smith and, first of all, of Ricardo.”
