"An unexamined life is not worth living" is a famous saying of the ancient Greek philosopher Socrates. Socrates is one of the pioneers of western philosophy. Socrates emphasized thinking and exploring the truth, and encouraged people to reflect on themselves in their daily lives. Socrates believes that everyone should keep a modest, reflective and thinking attitude, find their own mistakes and shortcomings, and strive to improve. Only by examining your own life can you have real meaning and value in life.
