"One is immediately aware of the deep commitment to dialogue that [Dr. Klein] possesses and the sincere respect he holds for everyone he encounters. His queries and responses, typically leavened with playful humor, consistently convey concern for both the perspective and the well-being of others and the community as a whole. It is evident at every turn that he cares what people think, feel, and believe. There are exceedingly few researchers who could demonstrate such a consistent and sure-footed understanding of fundamental human dilemmas."

"One of the best experiences I've had. Thoughtful and riveting."
