John K. Wood was one of the leading theoreticians and practitioners of the person-centered approach, its psychology and therapy. This welcome and well-presented book brings his work to a wider audience. His writings - on the person-centered approach as an approach, and on principles, groups and culture - reveal not only a widely-read and rigorous intellectual who is fearless in bringing his critical reflection to bear on his subjects, but also a passionate man deeply committed to radical practice and social change.
