The Tenth Letter of Plato, also known as Epistle X or Letter X, is an epistle that tradition has ascribed to Plato. It is the shortest of the Epistles of Plato, comprising two or three sentences aside from the salutation, and spanning a single letter in the Stephanus pagination (358c).
Few consider the Tenth Letter to be authentic. [1] It purports to be a private letter of encouragement to an otherwise unknown Aristodorus, commending him for his continued support of Dion, presumably during the latter's exile from Syracuse in his struggle for power with his nephew, Dionysius the Younger. Why such a letter would be preserved is unknown. More damaging to the letter's authenticity is its rather un-Platonic claim that genuine philosophy, which Aristodorus supposedly exhibits to the highest degree, consists entirely of steadfastness, trustworthiness, and sincerity, apparently to the exclusion of any intellectual qualities or even of any particular love of learning: any wisdom or cleverness which tends toward other moral commitments is rightly called "ingenuity" or "daintiness" (Bury translates "parlour-tricks;" Post, "embellishments;" κομψότητας).

Plato was an ancient Greek philosopher born in Athens during the Classical period in Ancient Greece. In Athens, Plato founded the Academy, a philosophical school where he taught the philosophical doctrines that would later became known as Platonism. Plato was a pen name derived from his nickname given to him by his wrestling coach – allegedly a reference to his physical broadness. According to Alexander of Miletus quoted by Diogenes of Sinope his actual name was Aristocles, son of Ariston, of the deme Collytus.
Proclus Lycius, called Proclus the Successor, was a Greek Neoplatonist philosopher, one of the last major classical philosophers of late antiquity. He set forth one of the most elaborate and fully developed systems of Neoplatonism and, through later interpreters and translators, exerted an influence on Byzantine philosophy, Early Islamic philosophy, and Scholastic philosophy.
Parmenides is one of the dialogues of Plato. It is widely considered to be one of the most challenging and enigmatic of Plato's dialogues. The Parmenides purports to be an account of a meeting between the two great philosophers of the Eleatic school, Parmenides and Zeno of Elea, and a young Socrates. The occasion of the meeting was the reading by Zeno of his treatise defending Parmenidean monism against those partisans of plurality who asserted that Parmenides' supposition that there is a one gives rise to intolerable absurdities and contradictions. The dialogue is set during a supposed meeting between Parmenides and Zeno of Elea in Socrates' hometown of Athens. This dialogue is chronologically the earliest of all as Socrates is only nineteen years old here. It is also notable that he takes the position of the student here while Parmenides serves as the lecturer.
The Laws is Plato's last and longest dialogue. The conversation depicted in the work's twelve books begins with the question of who is given the credit for establishing a civilization's laws. Its musings on the ethics of government and law have established it as a classic of political philosophy alongside Plato's more widely read Republic.
The Epinomis is a dialogue attributed to Plato. Some sources in antiquity began attributing its authorship to Philip of Opus, and many modern scholars consider it spurious. The dialogue continues the discussion undertaken in Plato's Laws.
Harold Fredrik Cherniss was an American classicist and historian of ancient philosophy. While at the Institute for Advanced Study in Princeton, he was said to be "the country's foremost expert on Plato and Aristotle."
The Seventh Letter of Plato is an epistle that tradition has ascribed to Plato. It is by far the longest of the epistles of Plato and gives an autobiographical account of his activities in Sicily as part of the intrigues between Dion and Dionysius of Syracuse for the tyranny of Syracuse. It also contains an extended philosophical interlude concerning the possibility of writing true philosophical works and the theory of forms. Assuming that the letter is authentic, it was written after Dion was assassinated by Calippus in 353 BC and before the latter was in turn overthrown a year later.
The Philebus is a Socratic dialogue written in the 4th century BC by Plato. Besides Socrates the other interlocutors are Philebus and Protarchus. Philebus, who advocates the life of physical pleasure (hedonism), hardly participates, and his position is instead defended by Protarchus, who learnt argumentation from Sophists. Socrates proposes there are higher pleasures as well as lower ones, and asks if the best life isn't one that optimally mixes both.
Minos is purported to be one of the dialogues of Plato. It features Socrates and a companion who together attempt to find a definition of "law".
The Epistles of Plato are a series of thirteen letters traditionally included in the Platonic corpus. Their authenticity has been the subject of some dispute, and scholarly consensus has shifted back and forth over time. They were "generally accepted as genuine until modern times"; but by the close of the nineteenth century, many philologists believed that none of the letters were actually written by Plato. Now every letter except the First has some defenders of its authenticity. The Twelfth is also widely regarded as a forgery, and the Fifth and Ninth have fewer supporters than the others.
The First Letter of Plato, also called Epistle I or Letter I, is an epistle that tradition has ascribed to Plato, though it is almost universally considered a forgery. In the Stephanus pagination, it spans III. 309a–310b.
The Twelfth Letter of Plato, also known as Epistle XII or Letter XII, is an epistle that tradition has ascribed to Plato, though it is almost certainly a literary forgery. Of all the Epistles, it is the only one that is followed by an explicit denial of its authenticity in the manuscripts. In the Stephanus pagination, it spans 359c–e of Vol. III.
The Ninth Letter of Plato, also called Epistle IX or Letter IX, is an epistle that is traditionally ascribed to Plato. In the Stephanus pagination, it spans III. 357d–358b.
Euphraeus was a philosopher and student of Plato from the town of Oreus in northern Euboea. He appears to have been active in politics in addition to his speculative studies, being first an adviser to Perdiccas III of Macedon and then an opponent of Philip II and his supporters in Oreus. Information regarding his life is scant, however, and few facts about it are mentioned in more than one source. He appears in the Fifth Letter of Plato, Demosthenes' Third Philippic, and Athenaeus' Deipnosophistae.
The Fifth Letter of Plato, also called Epistle V or Letter V, is an epistle that tradition has ascribed to Plato. It falls among those Epistles of Plato that have nothing to do with Sicilian politics and the intrigues between Dion and his nephew, Dionysius the Younger, tyrant of Syracuse. In the Stephanus pagination it spans III. 321c–322c.
The Second Letter of Plato, also called Epistle II or Letter II, is an epistle that tradition has ascribed to Plato, though some scholars consider it a forgery. In the Stephanus pagination, it spans III. 310b–315a.
The theory of Forms or theory of Ideas is a philosophical theory attributed to Plato, that the physical world is not as real or true as timeless, absolute, unchangeable ideas. According to this theory, ideas in this sense, often capitalized and translated as "Ideas" or "Forms", are the non-physical essences of all things, of which objects and matter in the physical world are merely imitations. Plato speaks of these entities only through the characters of his dialogues who sometimes suggests that these Forms are the only objects of study that can provide knowledge. The theory itself is contested from within Plato's dialogues, and it is a general point of controversy in philosophy. Nonetheless, the theory is considered to be a classical solution to the problem of universals.
Many interpreters of Plato held that his writings contain passages with double meanings, called allegories, symbols, or myths, that give the dialogues layers of figurative meaning in addition to their usual literal meaning. These allegorical interpretations of Plato were dominant for more than fifteen hundred years, from about the 1st century CE through the Renaissance and into the 18th century, and were advocated by major Platonist philosophers such as Plotinus, Porphyry, Syrianus, Proclus, and Marsilio Ficino. Beginning with Philo of Alexandria, these views influenced the Jewish, Christian, and Islamic interpretation of these religions' respective sacred scriptures. They spread widely during the Renaissance and contributed to the fashion for allegory among poets such as Dante Alighieri, Edmund Spenser, and William Shakespeare.
Plato's so-called unwritten doctrines are metaphysical theories ascribed to him by his students and other ancient philosophers but not clearly formulated in his writings. In recent research, they are sometimes known as Plato's 'principle theory' because they involve two fundamental principles from which the rest of the system derives. Plato is thought to have orally expounded these doctrines to Aristotle and the other students in the Academy and they were afterwards transmitted to later generations.
