This collection of 12 essays originated in the American Academy of Arts and Sciences, some of them appeared last year in the journal Daedalus. The contributors are: Henri Peyre, Henry Steele Commager, Helen Hill Miller, John Conway, D. Wilfred Abse and Lucie Jessner (collaborating), David C. McClelland, Adam Yarmolinsky, James MacGregor Burs, Don K. Price, Robert S. Morrison, and the two editors. With the exception of Mr. Yarmolinsky, who is a lawyer and presently holds an important position in Washington, it is wholly a roster of distinguished educators, many of them still young men. The essays are deployed very effectively across the entire range of the subject, covering not only the areas relating to education, but also its standards and roles in science and government, its bases in psychology, and its forms in other times, other civilizations. While a few of the pieces are formidably technical, all are closely argued and bristling with new approaches to, and theories about, excellence and leadership, which certainly are as necessary to society today as they are elusive of constructive thought.
