This book introduces Chinese philosophy in topics instead of the chronicle order. Five topics are included: what is the nature of the world; what are the relationships among things; what are social norms; what is the orientation of life; what is the cognitive structure. The first two parts are about nature or the world; the third and fourth parts are about society and human life; while the fifth part is about cognition and wisdom per se. This book is intended to give readers a basic understanding of Chinese philosophical thoughts, as well as of the greatest Chinese sages and their teachings.
