Greek philosophy is the study of ideas and knowledge developed by the ancient Greeks. They wanted to understand the world around them, so they asked questions about the nature of things. They believed that everything could be described in terms of basic elements, like earth, water, fire, and air, and that everything had an underlying goodness. Greek philosophers also studied topics like ethics and morality, and how to live a good and happy life. They wrote about their ideas in books and talked about them in classes. Greek philosophy still influences our thoughts and ideas today.
