This book aims to answer a simple question: What is philosophy? This work consists of five independent chapters, with the themes of philosophy and science, materialism and idealism, philosophical skepticism, philosophical practice, and individuality and wholeness. The author tries to avoid using obscure professional terms, hoping that people who don't know or have only a partial understanding of philosophy can also understand what philosophy is. This book is a classic introduction to philosophy.
As the author pointed out in the preface, this book is a book to popularize philosophical knowledge for the public. The author hopes that through the discussion of basic philosophical issues, readers can understand the value of philosophy, think about the meaning of life, enlighten their minds, and use it to guide their personal lives.
