In this book, prominent writers on psychotherapy present different, sometimes opposing views on humanity amp rsquo s dark side and consider how these views impact their clinical practice. Must therapists address the dark side in order to help people grow constructively? Or can they work to develop clients amp rsquo positive features without addressing the dark side at all? How does one help a victim of amp ldquo evil amp rdquo cope in therapy, and what if the client is a perpetrator?Additional chapters address broader implications, such as whether psychology is a fundamentally moral enterprise, whether human negativity is necessarily immoral, and how organizations that strive for virtue might instead perpetuate vice. Complete with engaging case studies, this book will stimulate dialogue on important philosophical issues that impact clinical practice and broader social interactions.
