Does "he lifted" mean "he plagiarized"?

Context:

A noteworthy feature of Murray Rothbard's monumental history of economic thought is his vigorous denunciation of Adam Smith and the Wealth of Nations. Smith was "an inveterate plagiarist," but one who "plagiarized badly, adding new fallacies to the truths he lifted." Smith's economics was a grave deterioration from is predecessors, from Cantillon, from Turgot, from his teacher Hutcheson, from the Spanish scholastics, even... from his own previous works." (Rothbard, pp.435-36)
