Alexander M. Carr-Saunders (14th January 1886-6th October 1966) was president of the London School of Economics from 1937 to 1956.  When his The Population Problem: A Study in Human Evolution appeared in 1922, it cemented his reputation.  According to his obituary in Population Studies this book has since been viewed as a seminal contribution to “social biology” due to its formulation of the “optimum number.”  Carr-Saunders defined the optimum number as the greatest number of individuals who could be sustained by a given environment.  For Carr-Saunders, moreover, this optimum number “involves the idea of the standard of living,” where in order to reach and to maintain this standard of living, populations, from primitive to civilized, employ practices to either “reduce fertility” or to “cause elimination,” including abortion, abstinence from sexual intercourse, and infanticide, in greater or lesser proportions (214.)

This was not all, however, as the maintenance of the highest standard of living possible required that the  “younger generation must become proficient in the skilled methods which makes this standard possible of attainment, and in particular it is important that young men should not marry unless they are both energetic and skillful.”  In such basic facts “we may see evidence exerted by social conditions and conventions” (224.)

Carr-Saunders has attracted some attention from Hayek scholars due to his influence on Hayek’s notion of cultural evolution.  Erik Angner in Hayek and Natural Law contends, “there is good reason to think that Hayek’s evolutionary thought was significantly inspired by Carr-Saunders and other Oxford zoologists” in particular supplying Hayek’s understanding of the mechanisms of group selection.
