Who Needs Light? is a prescription for what ails "the general suffering public" in our families and communities throughout the world's philosophically Cartesian cultures where thought is seen as more valuable than emotion. Beginning with infant brain development, the author identifies startlingly familiar influences of Darkness from a new point of view—that of the difference between Head People and Heart People.

The book includes a guide which defines the characteristics and habits of Abusive Personality Types. In lay terms, it shows how to identify and avoid these archetypal "Children of Darkness" wherever one might find them.

Dr. May uses case studies, meditative exercises, original poetry, science and oral history to lead us step-by-step through the oppressive forces of materialism, self-centeredness and authoritarian religions which have shaped our present-day civilization. Her final vision is one of hope and radical spiritual evolution.
