This study is an outgrowth of the author's personal interest in the subject and of a doctoral dissertation. The first chapter surveys the problem, and succeeding chapters deal with the philosophical, psychological, and theological concepts of Spirit, and with the spiritual dimension as it appears in the young child. A final chapter outlines implications of the study for an understanding of personality. A considerable literature in the fields of psychology, philosophy, and theology, is surveyed; but unfortunately, the antiseptic style of the doctoral dissertation seems to keep the author from revealing her own involvement in the subject or from letting the reader hear what conclusions have become her personal convictions. This limits the value of the book largely to that of a survey of the point of view of scholars and thinkers on the subject.
