In this book, Robert D. Nye clearly and succinctly presents the essential ideas of Freud, Skinner, and Rogers, three of the most important contributors to contemporary psychological thought.

A brief introductory chapter is followed by three chapters that provide an overview of each theorist. These chapters include basic ideas, practical examples, real-world implications, and commentaries. The final chapter provides comparisons on specific issues, critical evaluations, and the author's personal comments.
