Note 2 — Chapter II · New Incentives

See The Great Society, by Graham Wallas, for a psychological analysis of this change of social scale. I had the privilege of reading Mr. Wallas’s book in manuscript while I was revising this one. My obligations go far deeper than that, however, for they extend back to the spring of 1910, when Mr. Wallas came from England to lecture at Harvard. In A Preface to Politics I tried to express my sense of the way in which Graham Wallas marks a turning point in the history of political thinking.
