This is a classic must-read book on privacy, originally written in 1967 and finally back in print in this new edition, with a preface written by me. Excerpt from my preface: “At the core of the book is one of the most enduring discussions of the definition and value of privacy. Privacy is a very complex concept, and scholars and others have struggled for centuries to define it and articulate its value. Privacy and Freedom contains one of the most sophisticated, interdisciplinary, and insightful discussions of privacy ever written. Westin weaves together philosophy, sociology, psychology, and other disciplines to explain what privacy is and why we should protect it.”
