The Golden Rule, known in this country as the proverb: "What you do not want done to yourself, do not do to others," is gaining increasing popularity. For 200 years, it was overshadowed by Kant's categorical imperative. This book is the first monograph on the Golden Rule in Germany in almost 50 years. It makes a long-overdue contribution to a better understanding, ethical rehabilitation, and practical implementation of the Golden Rule. As a moral world heritage, it serves as an ideal guide for our lives. Its intention is simply to promote more humanity in our One World.
