“Vulgar economy actually does no more than interpret, systematise and defend in doctrinaire fashion the conceptions of the agents of bourgeois production who are entrapped in bourgeois production relations. It should not astonish us, then, that vulgar economy feels particularly at home in the estranged outward appearances of economic relations in which these prima facie absurd and perfect contradictions appear and that these relations seem the more self-evident the more their internal relationships are concealed from it, although they are understandable to the popular mind. But all science would be superfluous if the outward appearance and the essence of things directly coincided.”

“To paraphrase Leo Tolstoy, economic history is a deaf man answering questions no economist has put to him.”

“Like every living organism, the capitalist system reacts to "shocks" by creating ad hoc antibodies. This does not signify that it is immortal: no living organism is that. But it does show the mistake made by some analysts who take the agents of a survival which is real for the ferments of a death which is not.”

“Long dismissed as ideological representatives of the dominant powers, liberal economists have never experienced the pessimism of many modern Marxists regarding economic development of the periphery. It has come as something of a shock to Marxian writers that the empirical evidence on economic growth in the periphery since the Second World War has borne out much of the liberal case. Those countries which adopted strategies of export-oriented growth have achieved the most spectacular performance, while countries favouring self-sufficiency have done relatively poorly. Countries which have resisted distorting market prices have out-performed the heavily interventionist backward economies, which have in varying degrees emulated the Soviet model and and replaced economic mechanisms with direct controls and administrative allocation.”
