Chris Renwick’s recent research into the fate of William Beveridge’s attempt to establish social biology as the foundational social science at the London School of Economics is history at its best by uncovering a moment in the past when decisions were taken comparable to ones being taken today. In this case, the issues concern the political and scientific foundations of the welfare state. By connecting Beveridge’s original reasoning to recruit Lancelot Hogben for the Rockefeller-sponsored social biology chair with his later formative role in the design of the British welfare state, we are able to witness an alternative vision of the left, one associated with the Fabian movement, which proceeded independently of its Marxist cousin. The Fabian focus on taxing "inheritance" in the broadest sense remains relevant to how we think about the human condition in an era when capitalism has come to encompass the ownership of genetic material.
