Friedrich Hayek on Bernard Mandeville

“That we do not know why we do what we do, and that the consequences of our decisions are often very different from what we imagine them to be, are the two foundations of that satire on the conceits of a rationalist age which was his initial aim... [T]he speculations to which that je d'esprit led him mark the definite breakthrough in modern thought of the twin ideas of evolution and of the spontaneous formation of an order... Though Mandeville may have contributed little to the answers of particular questions of social and economic theory, he did, by asking the right questions, show that there was an object for a theory in this field. Perhaps in no case did he precisely show how an order formed itself without design, but he made it abundantly clear that it did, and thereby raised the questions to which theoretical analysis, first in the social sciences and later in biology, could address itself.”

“I do not intend to pitch my claim on behalf of Mandeville higher than to say that he made Hume possible. It is indeed my estimate of Hume as perhaps the greatest of all modern students of mind and society which makes Mandeville appear to me so important. It is only in Hume's work that the significance of Mandeville's efforts becomes wholly clear, and it was through Hume that he exercised his most lasting influence. Yet to have given Hume some of his leading conceptions seems to me sufficient title for Mandeville to qualify as a master mind.”

“How much Mandeville's contribution meant we recognise when we look at the further development of those conceptions which Hume was the first and greatest to take up and elaborate. This development includes...the great Scottish moral philosophers of the second half of the century, above all Adam Smith and Adam Ferguson, the latter of whom, with his phrase about the "results of human action but not of human design", has provided not only the best brief statement of Mandeville's central problem but also the best definition of the task of all social theory... [T]he tradition which Mandeville started includes Edmund Burke, and, largely through Burke, all those "historical schools" which, chiefly on the Continent, and through men like Herder and Savigny, made the idea of evolution a commonplace in the social sciences of the nineteenth century long before Darwin. And it was in this atmosphere of evolutionary thought in the study of society, where "Darwinians before Darwin" had long thought in terms of the prevailing of more effective habits and practices, that Charles Darwin at last applied the idea systemically to biological organisms. I do not, of course, mean to suggest that Mandeville had any direct influence on Darwin (though David Hume probably had). But it seems to me that in many respects Darwin is the culmination of a development which Mandeville more than any other single man has started.”
