In 1947 Air Force Project RAND—then a branch of Douglas Aircraft, but soon to become the independent RAND Corporation—decided that it needed to recruit social scientists to aid it in its studies of prospective military technologies. As a step forward it held a conference of social scientists that September. The director of natural sciences at the Rockefeller Foundation, mathematician Warren Waver, delivered the conference’s opening remarks.
Asking the rhetorical question of why they had assembled there, Weaver began by explaining: “I take it that every person in this room is fundamentally interested and devoted to what you can just broadly call the rational life.”
As I note in a parallel post at Ether Wave Propaganda, the remark was first quoted in journalist Fred Kaplan’s 1983 book The Wizards of Armageddon, where it is truncated and explained in such a way that it appears to augur an attempt to marshall social scientists into an attempt “impose” a rational order on military strategy and national policy. The “rational life” quote has been used by a number of other authors since Kaplan’s book appeared, and the meaning of the term has always been taken for granted. This post explores what Weaver had in mind.
