This book shares Li Erming's reflections after forty years of studying philosophy. It is written for like-minded people of his generation who love philosophy and hope to live wisely and with clear minds. The book discusses the origins of philosophy, its founders, the problems philosophy sets out to solve, why some people resist clarity, the benefits of studying philosophy, and its practical relevance to people today. It is my hope that these reflections will help readers in their lives, and that everyone can enjoy a happy and fulfilling life.
