"Henry C. Simons... his pamphlet, A Positive Program for Laissez Faire, offered a new and common basis for the aspirations of America’s young liberals. Hopes for a systematic and comprehensive work from Simons were disappointed; instead, he left a collection of essays which appeared in 1948 under the title Economic Policy for a Free Society. This book became very influential owing to its wealth of ideas and to the courage with which Simons discussed such delicate problems as trade unionism. Today, the nucleus of a group of like-minded economists—no longer confined to Chicago—is formed by Simons’ closest friend, Aaron Director, and two of the best-known younger American theoreticians, George Stigler and Milton Friedman. Director has edited Simons’ papers and carried on his work."
