Plato
✨ c. 428–348 BCE, Philosophy
Plato was a Greek philosopher who lived in Athens during the 5th and 4th centuries BCE, probably from around 428/427 to 348/347 BCE. He was a student of Socrates and later became the teacher of Aristotle.
After the death of Socrates, Plato founded the Academy in Athens around 387 BCE, one of the earliest organized centers of philosophical and scientific study in the Greek world. His works are mainly written as dialogues, in which characters discuss questions about knowledge, justice, politics, education, and the nature of reality.
Among Plato’s most famous ideas is the theory of Forms, according to which the visible world is connected to more stable and perfect realities that the mind can understand through reasoning. In his dialogue The Republic, he explored the meaning of justice and described his vision of an ideal state led by philosopher-kings.
Plato’s writings influenced later philosophy, science, religion, and political thought for centuries. Although some of his ideas have been debated and criticized, his methods of questioning and discussion remain important in education and intellectual history.
