Plato was born around the year 428 BCE in Athens. His father died while Plato was young, and his mother remarried Pyrilampes, in whose house Plato would grow up. Plato's birth name was Aristocles, and he gained the nickname Platon, meaning broad, because of his broad build. His family had a history in politics, and Plato was destined for a life in keeping with this history. He studied at a gymnasium owned by Dionysios, and at the palaistra of Ariston of Argos. When he was young he studied music and poetry. According to Aristotle, Plato developed the foundations of his metaphysics and epistemology by studying the doctrines of Cratylus, and the work of Pythagoras and Parmenides. When Plato met Socrates, however, he had met his definitive teacher. As Socrates' disciple, Plato adopted his philosophy and style of debate and directed his studies toward the question of virtue and the formation of a noble character.

Education: Apuleius informs us that Speusippus praised Plato's quickness of mind and modesty as a boy, and the "first fruits of his youth infused with hard work and love of study". Plato must have been instructed in grammar, music, and gymnastics by the most distinguished teachers of his time. Dicaearchus went so far as to say that Plato wrestled at the Isthmian games. Plato had also attended courses in philosophy; before meeting Socrates, he first became acquainted with Cratylus (a disciple of Heraclitus, a prominent pre-Socratic Greek philosopher) and the Heraclitean doctrines. W. A. Borody argues that an Athenian openness towards a wider range of sexuality may have contributed to the Athenian philosophers’ openness towards a wider range of thought, a cultural situation Borody describes as “polymorphously discursive."

Later life: Plato may have travelled to Italy, Sicily, Egypt and Cyrene. Said to have returned to Athens at the age of forty, Plato founded one of the earliest known organized schools in Western Civilization on a plot of land in the Grove of Hecademus or Academus. The Academy was "a large enclosure of ground that was once the property of a citizen at Athens named Academus (some, however, say that it received its name from an ancient hero). The Academy operated until it was destroyed by Lucius Cornelius Sulla in 84 BC. Neoplatonists revived the Academy in the early 5th century, and it operated until AD 529 when it was closed by Justinian I of Byzantium, who saw it as a threat to the propagation of Christianity. Many intellectuals were schooled in the Academy, the most prominent one being Aristotle.

Throughout his later life, Plato became entangled with the politics of the city of Syracuse. According to Diogenes Laertius, Plato initially visited Syracuse while it was under the rule of Dionysus. During this first trip Dionysus's brother-in-law, Dion of Syracuse, became one of Plato's disciples, but the tyrant himself turned against Plato. Plato was sold into slavery and almost faced death in Cyrene, a city at war with Athens before an admirer bought Plato's freedom and sent him home. After Dionysius's death, according to Plato's Seventh Letter, Dion requested Plato return to Syracuse to tutor Dionysus II and guide him to become a philosopher-king. Dionysius II seemed to accept Plato's teachings, but he became suspicious of Dion, his uncle. Dionysus expelled Dion and kept Plato against his will. Eventually, Plato left Syracuse. Dion would return to overthrow Dionysus and rule Syracuse for a short time before being usurped by Calippus, a fellow disciple of Plato.

Major Writings: After 399 BC Plato began to write extensively. It is still up for debate whether he was writing before Socrates' death, and the order in which he wrote his major texts is also uncertain. However, most scholars agree to divide Plato's major work into three distinct groups. The first of these is known as the Socratic Dialogues because of how close he stays within the text to Socrates' teachings. They were probably written during the years of his travels between 399 and 387 BC. One of the texts in this group called the Apology seems to have been written shortly after Socrates' death. Other texts relegated to this group include the Crito, Laches, Lysis, Charmides, Euthyphro, and Hippias Minor and Major.

Plato returned to Athens in 387 BC and, on land that had once belonged to Academic, he founded a school of learning which he called the Academy. Plato's school is often described as the first European university. Its curriculum offered subjects including astronomy, biology, mathematics, political theory, and philosophy. Plato hoped the Academy would provide a place where thinkers could work toward better government in the Grecian cities. He would preside over the Academy until his death.

The period from 387 to 361 BC is often called Plato's "middle" or transitional period. It is thought that he may have written the Meno, Euthydemus, Menexenus, Cratylus, Republic, Phaedrus, Symposium and Phaedo during this time. The major difference between these texts and his earlier works is that he tends toward grander metaphysical themes and begins to establish his own voice in philosophy. Socrates still has a presence, however, sometimes as a fictional character. In the Meno for example Plato writes of the Socratic idea that no one knowingly does wrong, and adds the new doctrine of recollection questioning whether virtue can be taught. In the Phaedo, we are introduced to the Platonic doctrine of the Forms, in which Plato makes claims as to the immortality of the human soul. The middle dialogues also reveal Plato's method of hypothesis.

Plato's most influential work, The Republic, is also a part of his middle dialogues. It is a discussion of the virtues of justice, courage, wisdom, and moderation, of the individual and in society. It works with the central question of how to live a good life, asking what an ideal State would be like, and what defines a just individual. These lead to more questions regarding the education of citizens, how government should be formed, the nature of the soul, and the afterlife. The dialogue finishes by reviewing various forms of government and describing the ideal state, where only philosophers are fit to rule. The Republic covers almost every aspect of Plato's thought.

Later Life/ Death: A variety of sources have given accounts of Plato's death. One story, based on a mutilated manuscript, suggests Plato died in his bed, whilst a young Thracian girl played the flute to him. Another tradition suggests Plato died at a wedding feast. The account is based on Diogenes Laertius's reference to an account by Hermippus, a third-century Alexandrian. According to Tertullian, Plato simply died in his sleep
