When did Plato start the Academy?

What was later to be known as Plato's school probably originated around the time Plato inherited the property at the age of thirty, with informal gatherings which included Theaetetus of Sunium, Archytas of Tarentum, Leodamas of Thasos, and Neoclides. According to Debra Nails, Speusippus "joined the group in about 390 BC". She claims, "It is not until Eudoxus of Cnidos arrives in the mid-380s BC that Eudemus recognizes a formal Academy." There is no historical record of the exact time the school was officially founded, but modern scholars generally agree that the time was the mid-380s, probably sometime after 387 BC, when Plato is thought to have returned from his first visit to Italy and Sicily. Originally, the meetings were held on Plato's property as often as they were at the nearby Academy gymnasium; this remained so throughout the fourth century.

The Academy (Ancient Greek: Ἀκαδημία) was founded by Plato (428/427 BC – 348/347 BC) in c. 387 BC in Athens. Aristotle (384–322 BC) studied there for twenty years (367–347 BC) before founding his own school, the Lyceum. The Academy persisted throughout the Hellenistic period as a skeptical school, until coming to an end after the death of Philo of Larissa in 83 BC. The Platonic Academy was destroyed by the Roman dictator Sulla in 86 BC.

An argument that has been used against ascribing ironic intent to Plato is that Plato's Academy produced a number of tyrants who seized political power and abandoned philosophy for ruling a city. Despite being well-versed in Greek and having direct contact with Plato himself, some of Plato's former students like Clearchus, tyrant of Heraclea; Chaeron, tyrant of Pellene; Erastus and Coriscus, tyrants of Skepsis; Hermias of Atarneus and Assos; and Calippus, tyrant of Syracuse ruled people and did not impose anything like a philosopher-kingship. However, it can be argued whether these men became "tyrants" through studying in the Academy. Plato's school had an elite student body, some of whom would by birth, and family expectation, end up in the seats of power. Additionally, it is important to remember that it is by no means obvious that these men were tyrants in the modern, totalitarian sense of the concept. Finally, since very little is actually known about what was taught at Plato's Academy, there is no small controversy over whether it was even in the business of teaching politics at all.

In at least Plato's time, the school did not have any particular doctrine to teach; rather, Plato (and probably other associates of his) posed problems to be studied and solved by the others. There is evidence of lectures given, most notably Plato's lecture "On the Good"; but probably the use of dialectic was more common. According to an unverifiable story, dated of some 700 years after the founding of the school, above the entrance to the Academy was inscribed the phrase "Let None But Geometers Enter Here."

The original Academy of Plato had been destroyed by the Roman dictator Sulla in 86 BC. Several centuries later, in 410 AD, a Neoplatonic academy was established that had no institutional continuity with Plato's Academy, and which served as a center for Neoplatonism and mysticism. It persisted until 529 AD when it was finally closed by Justinian I. Other schools in Constantinople, Antioch, and Alexandria, which were the centers of Justinian's empire, continued.

When a military junta ('the Colonels') took power in 1967, he was one of the many intellectuals arrested, sacked from their posts then confined to restricted residence. He then started what he called an informal new 'Plato's Academy' - his old students would gather at his house in Athens and his teaching continued there.

Despite the Platonic Academy being destroyed in the first century BC, the philosophers continued to teach Platonism in Athens during the Roman era, but it was not until the early 5th century (c. 410) that a revived academy (which had no connection with the original Academy) was established by some leading Neoplatonists. The origins of Neoplatonist teaching in Athens are uncertain, but when Proclus arrived in Athens in the early 430s, he found Plutarch of Athens and his colleague Syrianus teaching in an Academy there. The Neoplatonists in Athens called themselves "successors" ("diadochoi", but of Plato) and presented themselves as an uninterrupted tradition reaching back to Plato, but there cannot have actually been any geographical, institutional, economic or personal continuity with the original academy. The school seems to have been a private foundation, conducted in a large house which Proclus eventually inherited from Plutarch and Syrianus. The heads of the Neoplatonic Academy were Plutarch of Athens, Syrianus, Proclus, Marinus, Isidore, and finally Damascius. The Neoplatonic Academy reached its apex under Proclus (died 485).

The Neoplatonic Florentine Academy was founded after Gemistus Pletho reintroduced Plato's thoughts to Western Europe during the 1438–39 Council of Florence. It was sponsored by Cosimo de' Medici, led by Marsilio Ficino and supported by Medici until death of Lorenzo Medici. It was never a formal group but the members considered themselves a modern form of Plato's Academy. Important members were Poliziano, Cristoforo Landino, Pico della Mirandola, and Gentile de' Becchi. The academy would proceed to translate into Latin all of Plato's works, the Enneads of Plotinus, and various other Neoplatonic works.

Platonism was originally expressed in the dialogues of Plato, in which the figure of Socrates is used to expound certain doctrines, that may or may not be similar to the thought of the historical Socrates, Plato's master. Plato delivered his lectures at the Academy, a precinct containing a sacred grove outside the walls of Athens. The school continued there long after Plato's death. There were three periods: the Old, Middle, and New Academy. The chief figures in the Old Academy were Speusippus (Plato's nephew), who succeeded him as the head of the school (until 339 BC), and Xenocrates (until 313 BC). Both of them sought to fuse Pythagorean speculations on number with Plato's theory of forms.

In ancient Greece, after the establishment of the original Academy, Plato's colleagues and pupils developed spin-offs of his method. Arcesilaus, a Greek student of Plato established the Middle Academy. Carneades, another student, established the New Academy. In 335 BC, Aristotle refined the method with his own theories and established the Lyceum in another gymnasium.

Diogenes Laërtius divided the history of the Academy into three: the Old, the Middle, and the New. At the head of the Old he put Plato, at the head of the Middle Academy, Arcesilaus, and of the New, Lacydes. Sextus Empiricus enumerated five divisions of the followers of Plato. He made Plato founder of the first Academy; Arcesilaus of the second; Carneades of the third; Philo and Charmadas of the fourth; and Antiochus of the fifth. Cicero recognised only two Academies, the Old and New, and had the latter commence with Arcesilaus.
