0Since its publication in 1966, The Triumph of the Therapeutic has been hailed as a work of genuine brilliance, one of those books whose insights uncannily anticipate cultural developments and whose richness of argumentation reorients entire fields of inquiry. This special fortieth-anniversary edition of Philip Rieff's masterpiece, the first volume in ISI Books' new Background series, includes an introduction by Elisabeth Lasch-Quinn and essays on the text by historians Eugene McCarraher and Wilfred McClay and philosopher Stephen Gardner.
