The spatial concepts delineated in the title are the boundaries marking the domains of psychoanalytical theory (inner space) and social psychiatry (outer space). It is Dr. Rabkin's belief that the two schools of thought are separated by major differences in fundamental assumptions. In a series of searching chapters he explores philosophically, linguistically, and historically how these differences came about and what meaning or non-meanings may be attached to ideas such as the uniqueness of the individual, the familiar dichotomies mind-body, instinct-habit, nature-nurture, and a variety of terms familiar to students of Freudianism or neo-Freudianism. Dr. Rabkin strongly opposes the psychoanalytical approach on both theoretical and practical grounds and postulates a dynamic social psychiatric theory involving notions of networks of people, ""natural groups"" whose interactions may be observed. Where problems exist, the use of candor and open Communications may effect a change in behavior. The book addresses itself to the community of specialists but the broad scope of ideas discussed and the use of literary and cross-cultural references invites the attention of sophisticated, thoughtful readers.
