A few days ago I finished studying Sex and Culture for the second time. It is a remarkable book summarizing a lifetime of research by Oxford social anthropologist J.D. Unwin.[1] The 600+ page book is, in Unwin’s words, only a “summary” of his research—seven volumes would be required to lay it all out.[2] His writings suggest he was a rationalist, believing that science is our ultimate tool of inquiry (it appears he was not a religious man). As I went through what he found, I was repeatedly reminded of the thought I had as a philosophy student: some moral laws may be designed to minimize human suffering and maximize human flourishing long term.
