This book challenges the very foundation of traditional medicine with a controversial and fascinating idea: using neurosurgical intervention and behavior modification to reintegrate sociopaths into modern society. Written in accessible language, it explores the groundbreaking work of Dr. Antônio De Salles, who pioneers this approach at the intersection of medicine, science, technology, and human interaction. The book's thought-provoking content makes it a must-read for students and academics across various disciplines, from the sciences to the humanities. It illuminates the complex medical, technical, and moral implications of this sensitive issue, encouraging readers to grapple with the ethical questions raised by this emerging field of study. "The field of psychosurgery promises to change how we think about science and mental illness. Already, brain surgery is safe enough, and implants are sophisticated enough, for alteration of the brain to be accepted as mainstream therapy." - Hays and Berenbein.
