Why would anyone want there to be natural foundations for the social sciences? In a provocative essay exploring precisely that question, historian Chris Renwick uses an interwar debate featuring William Beveridge, Lancelot Hogben, and Friedrich Hayek to begin to imagine what might have been had such a program calling for biological knowledge to form the natural bases of the social sciences been realized at the London School of Economics. Yet perhaps Renwick grants too much attention to differences and "what-ifs" and not enough to the historical question of "what happened" afterward. "Chickens and Eggs" offers an alternative view of this rather vexed question—one grounded in what happened, which suggests that Renwick’s concerns may be somewhat misplaced.
