Socrates didn’t write any books on philosophy—we know about him only through the works of others, mainly dialogues written by two of his most famous students, Plato and Xenophon. According to legend, Socrates was the first person to apply the philosophical method to ethical questions. He particularly wanted to help others to live wisely, in accord with reason. For Socrates, philosophy was not only a moral guide but also a kind of psychological therapy. Doing philosophy, he said, can help us overcome our fear of death, improve our character, and even find a genuine sense of fulfillment.
