Undoing the Clinch of Oppression

Bridging the gap between psychology and politics, Lichtenberg presents a powerful argument for applying the methods and insights of the Gestalt perspective to social and political problems. Focusing on the inner dynamics of power and abuse relationships, this thoughtful treatment of victim/oppressor fusion has stimulated new thinking about abuse, exploitation, and the processes and methods essential to personal and political change.
