Plato in the context of "Aristotle"

Classical Athens, known contemporaneously simply as Athens (Ancient Greek: Ἀθῆναι, Athênai [atʰɛ̂ːnai̯]; Modern Greek: Αθήναι, Athine [aˈθine]), was the major urban centre of the notable polis (city-state) of the same name during the classical period (480–323 BC) of ancient Greece, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions, it remained in place for 180 years, until 322 BC (amid the aftermath of the Lamian War). The peak of Athenian hegemony was achieved during the Age of Pericles in the 440s and 430s BC.

In the classical period, Athens was a centre for the arts, learning, and philosophy, and it was the home of Plato's Academy and Aristotle's Lyceum. Athens was also the birthplace of Socrates, Plato, Pericles, Aristophanes, Sophocles, and many other prominent philosophers, writers, and politicians of the ancient world. It is widely referred to as the cradle of Western civilization and as the birthplace of democracy, largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC on the rest of the then-known European continent.

A tragedy is a genre of drama based on human suffering and, mainly, the terrible or sorrowful events that befall a main character or cast of characters. Traditionally, the intention of tragedy is to invoke an accompanying catharsis, or a "pain [that] awakens pleasure," for the audience. While many cultures have developed forms that provoke this paradoxical response, the term tragedy often refers to a specific tradition of drama that has played a unique and important role historically in the self-definition of Western civilization. That tradition has been multiple and discontinuous, yet the term has often been used to invoke a powerful effect of cultural identity and historical continuity—"the Greeks and the Elizabethans, in one cultural form; Hellenes and Christians, in a common activity," as Raymond Williams puts it.

Originating in the theatre of ancient Greece 2500 years ago, where only a fraction of the works of Aeschylus, Sophocles and Euripides survive, as well as many fragments from other poets, and the later Roman tragedies of Seneca; through its singular articulations in the works of Shakespeare, Lope de Vega, Jean Racine, and Friedrich Schiller to the more recent naturalistic tragedy of Henrik Ibsen and August Strindberg; Nurul Momen's Nemesis' tragic vengeance & Samuel Beckett's modernist meditations on death, loss and suffering; Heiner Müller postmodernist reworkings of the tragic canon, tragedy has remained an important site of cultural experimentation, negotiation, struggle, and change. A long line of philosophers—which includes Plato, Aristotle, Saint Augustine, Voltaire, Hume, Diderot, Hegel, Schopenhauer, Kierkegaard, Nietzsche, Freud, Benjamin, Camus, Lacan, and Deleuze—have analysed, speculated upon, and criticised the genre.

The Academy (Ancient Greek: Ἀκαδημία, romanized: Akadēmia) was founded by Plato in ca. 387 BC in Athens. Aristotle studied there for twenty years (367 BC – 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. Although philosophers continued to teach Plato's philosophy in Athens during the Roman era, it was not until AD 410 that a revived Academy was re-established as a center for Neoplatonism, persisting until 529 AD when it was closed down by Justinian I.

The Lyceum (Ancient Greek: Λύκειον, romanized: Lykeion) was a temple in Athens dedicated to Apollo Lyceus ("Apollo the wolf-god").

It was best known for the Peripatetic school of philosophy founded there by Aristotle in 334 BC. Aristotle fled Athens in 323 BC, and the university continued to function after his lifetime under a series of leaders until the Roman general Sulla destroyed it during his assault on Athens in 86 BC.

Socrates (/ˈsɒkrətiːz/; Ancient Greek: Σωκράτης, romanized: Sōkrátēs; c. 470 – 399 BC) was an ancient Greek philosopher from Classical Athens, perhaps the first Western moral philosopher, and a major inspiration on his student Plato, who largely founded the tradition of Western philosophy. An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon. These accounts are written as dialogues, in which Socrates and his interlocutors examine a subject in the style of question and answer; they gave rise to the Socratic dialogue literary genre. Contradictory accounts of Socrates make a reconstruction of his philosophy nearly impossible, a situation known as the Socratic problem. Socrates was a polarizing figure in Athenian society. In 399 BC, he was accused of impiety and corrupting the youth. After a trial that lasted a day, he was sentenced to death. As related by Plato, he was put to death by administration of poison after refusing offers from allies to help him escape.

Plato's dialogues are among the most comprehensive accounts of Socrates to survive from antiquity. They demonstrate the Socratic approach to areas of philosophy including epistemology and ethics. The Platonic Socrates lends his name to the concept of the Socratic method, and also to Socratic irony. The Socratic method of questioning, or elenchus, takes shape in dialogue using short questions and answers, epitomized by those Platonic texts in which Socrates and his interlocutors examine various aspects of an issue or an abstract meaning, usually relating to one of the virtues, and find themselves at an impasse, unable to define what they thought they understood. Socrates frequently proclaims his ignorance, saying that he is only sure that he does not know.

Aristophanes (/ˌærɪˈstɒfəniːz/; Ancient Greek: Ἀριστοφάνης [aristopʰánɛːs]; c. 446 – c. 386 BC) was an Ancient Greek comic playwright from Athens. He wrote in total forty plays, of which eleven survive virtually complete today. The majority of his surviving plays belong to the genre of comic drama known as Old Comedy and are considered its most valuable examples. Aristophanes's plays were performed at the religious festivals of Athens, mostly the City Dionysia and the Lenaia, and several of them won the first prize in their respective competitions.

Also known as "The Father of Comedy" and "the Prince of Ancient Comedy", Aristophanes wrote plays that often dealt with real-life figures, including Euripides and Alcibiades, and contemporary events, such as the Peloponnesian War. He has been said to recreate the life of ancient Athens more convincingly than any other author. His plays are characterized by preposterous premises, explicit language, wordplays, and political satire. His powers of ridicule were feared and acknowledged by influential contemporaries; Plato singled out Aristophanes's play The Clouds as slander that contributed to the trial and subsequent condemning to death of Socrates, although other satirical playwrights had also caricatured the philosopher.

In semiotics, khôra (also chora; Ancient Greek: χώρα) is the space that gives a place for being. The term has been used in philosophy by Plato to designate a receptacle (as a "third kind" [triton genos]; Timaeus 48e4), a space, a material substratum, or an interval. In Plato's account, khôra is described as a formless interval, alike to a non-being, in between which the "Forms" were received from the intelligible realm (where they were originally held) and were "copied", shaping into the transitory forms of the sensible realm; it "gives space" and has maternal overtones (a womb, matrix):

Sophia, or Sofia (Koine Greek: σοφία, sophía—"wisdom") is a central idea in Hellenistic philosophy and religion, Platonism, and Gnosticism. Originally carrying a meaning of "cleverness, skill", the later meaning of the term, close to the meaning of phronesis ("wisdom, intelligence"), was significantly shaped by the term philosophía ("love of wisdom") as used by Plato.

In the Orthodox Church and the Catholic Church, the feminine personification of divine wisdom as Holy Wisdom (Ἁγία Σοφία; Hagía Sophía) can refer either to Jesus Christ the Word of God (as in the dedication of the church of Hagia Sophia in Constantinople) or to the Holy Spirit.
