Ancient philosophy refers to the philosophical ideas and systems developed in ancient civilizations, particularly in Greece and Rome. Key figures include Socrates, Plato, and Aristotle, who explored fundamental questions about existence, knowledge, ethics, and the nature of reality. Their works laid the groundwork for Western philosophical thought. In addition to Greek philosophy, ancient traditions also emerged in India and China. Philosophers like Confucius and Laozi contributed to moral and political philosophy, while Indian thinkers developed concepts in Buddhism and Hinduism. These diverse traditions shaped human understanding and continue to influence modern philosophy.
