Evil and Moral Psychology - Clear Account of Evil Persons

In this review of Evil and Moral Psychology, the reviewer finds a thoughtful, philosophically rigorous book for readers who want a clearer account of what it is to be an evil person rather than a merely bad one. Peter Brian Barry approaches the topic from the intersection of ethics and psychology, making this work particularly useful for philosophers, psychologists, legal scholars, and anyone wrestling with the language of moral condemnation. The book's single biggest strength is its sustained effort to ground philosophical claims in psychological research, offering a measured, analytic alternative to rhetorical uses of the word evil.

Key Features

• Interdisciplinary approach: Combines moral philosophy with findings from abnormal and social psychology to give a nuanced description of evil agents.
• Philosophical clarity: Offers a systematic account of what makes someone an evil person rather than relying on loose moral rhetoric.
• Institutional implications: Explores how the account of evil affects social, legal, and criminal institutions and policy thinking.
• Engagement with common usage: Critically examines contemporary phrases like the axis of evil and the casual labeling of opponents as evil.
• Research-informed reasoning: Uses psychological studies to test and illustrate philosophical claims about moral psychology.

Who It's For

This book will be most valuable to graduate students and scholars in philosophy and psychology who seek a precise conceptual treatment of moral villainy grounded in empirical research. It also suits legal theorists and criminal justice professionals interested in how concepts of evil might bear on institutional responses and culpability.

Readers looking for a popular history, a self-help manual, or a strictly theological exploration of the problem of evil should look elsewhere; Barry is addressing moral psychology and institutional implications, not devotional or purely religious explanations.
