Two opening statements by Heinz Hartmann and Ernest Nagel set the tone for the debate and discussion that followed. These are followed by social scientific statements of Abram Kardiner, Ernest van den Haag, and Alex Inkeles, followed by the philosophers Morris Lazerowitz, Donald C. Williams, and Anthony Flew. Such distinguished scholars as Adolf Grunbaum, Michael Scriven, Gail Kennedy, Arthur Pap, Philipp Frank. Arthur C. Danto, Max Black and others, round out this pioneering effort in the literature of intellectual combat.

Sidney Hook applies to his vision of psychoanalysis the same compelling rigor he applied to other would-be advocates of a science beyond ordinary scientific method or safeguards. He nonetheless points out that even therapeutic success is not the last word, but must itself be tested on a variety of measures: statistical no less than analytical. This remains a courageous and disturbing work, one that commands attention among practicing psychiatrists, psychoanalysts-and their would-be patients.
