Plato, born Aristocles, was an ancient Greek philosopher of the Classical period who is considered a foundational thinker in Western philosophy and an innovator of the written dialogue and dialectic forms. He raised problems for what became all the major areas of both theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the doctrines that would later become known as Platonism.
Aristocracy is a form of government that places power in the hands of a small, privileged ruling class, the aristocrats.
A sophist was a teacher in ancient Greece in the fifth and fourth centuries BCE. Sophists specialized in one or more subject areas, such as philosophy, rhetoric, music, athletics and mathematics. They taught arete, "virtue" or "excellence", predominantly to young statesmen and nobility.
Ancient Greek philosophy arose in the 6th century BC. Philosophy was used to make sense of the world using reason. It dealt with a wide variety of subjects, including astronomy, epistemology, mathematics, political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric and aesthetics. Greek philosophy continued throughout the Hellenistic period and later evolved into Roman philosophy.
Eudaimonia, sometimes anglicized as eudaemonia or eudemonia, is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'.
Laconophilia is love or admiration of Sparta and of the Spartan culture or constitution. The term derives from Laconia, the part of the Peloponnesus where the Spartans lived.
The Open Society and Its Enemies is a work on political philosophy by the philosopher Karl Popper, in which the author presents a "defence of the open society against its enemies", and offers a critique of theories of teleological historicism, according to which history unfolds inexorably according to universal laws. Popper indicts Plato, Hegel, and Marx for relying on historicism to underpin their political philosophies.
In historical scholarship, the Socratic problem concerns attempts at reconstructing a historical and philosophical image of Socrates based on the variable, and sometimes contradictory, nature of the existing sources on his life. Scholars rely upon extant sources, such as those of contemporaries like Aristophanes or disciples of Socrates like Plato and Xenophon, for knowing anything about Socrates. However, these sources contain contradictory details of his life, words, and beliefs when taken together. This complicates the attempts at reconstructing the beliefs and philosophical views held by the historical Socrates. It has become apparent to scholarship that this problem is seemingly impossible to clarify and thus perhaps now classified as unsolvable. Early proposed solutions to the matter still pose significant problems today.
Phædo or Phaedo, also known to ancient readers as On The Soul, is one of the best-known dialogues of Plato's middle period, along with the Republic and the Symposium. The philosophical subject of the dialogue is the immortality of the soul. It is set in the last hours prior to the death of Socrates, and is Plato's fourth and last dialogue to detail the philosopher's final days, following Euthyphro, Apology, and Crito.
The First Alcibiades, also referred to as Alcibiades Major and abbreviated as Alcibiades I, is a dialogue ascribed to Plato, depicting Socrates in conversation with Alcibiades.
Republic is a Socratic dialogue, authored by Plato around 375 BC, concerning justice, the order and character of the just city-state, and the just man. It is Plato's best-known work, and one of the world's most influential works of philosophy and political theory, both intellectually and historically.
Thrasymachus was a sophist of ancient Greece best known as a character in Plato's Republic.
The philosopher king is a hypothetical ruler in whom political skill is combined with philosophical knowledge. The concept of a city-state ruled by philosophers is first explored in Plato's Republic, written around 375 BC. Plato argued that the ideal state – one which ensured the maximum possible happiness for all its citizens – could only be brought into being by a ruler possessed of absolute knowledge, obtained through philosophical study. From the Middle Ages onwards, Islamic and Jewish authors expanded on the theory, adapting it to suit their own conceptions of the perfect ruler.
The Ship of State is an ancient and oft-cited metaphor, famously expounded by Plato in the Republic, which likens the governance of a city-state to the command of a vessel. Plato expands the established metaphor and ultimately argues that the only people fit to be captain of the ship are philosopher kings, benevolent men with absolute power who have access to the Form of the Good. The origins of the metaphor can be traced back to the lyric poet Alcaeus, and it is also found in Aeschylus' Seven Against Thebes, Sophocles' Antigone and Aristophanes' Wasps before Plato. During the Renaissance Sebastian Brant amplified and reworked Plato's text in a satirical book The Ship of Fools which was translated soon in Latin, French and English
Callicles is thought to have been an ancient Athenian political philosopher. He figures prominently in Plato’s dialogue Gorgias, where he "presents himself as a no-holds-barred, bare-knuckled, clear-headed advocate of Realpolitik". In terms of dramatic action, his function in the dialogue is to provide a counter-argument to Plato's philosophical ideas. The absence of contemporaneous sources external to this single text attesting to his existence has suggested to some that he may be no more than a character created by Plato for the dialogue. In this vein, it has also been proposed that Callicles may have been devised by Plato as he imagined what kind of intellectual he might have become had he not met with Socrates and undergone his formative philosophical life under the latter's tutelage. He is the antithesis to Socrates.
The history of political thought encompasses the chronology and the substantive and methodological changes of human political thought. The study of the history of political thought represents an intersection of various academic disciplines, such as philosophy, law, history and political science.
A sage, in classical philosophy, is someone who has attained wisdom. The term has also been used interchangeably with a 'good person', and a 'virtuous person'. Among the earliest accounts of the sage begin with Empedocles' Sphairos. Horace describes the Sphairos as "Completely within itself, well-rounded and spherical, so that nothing extraneous can adhere to it, because of its smooth and polished surface." Alternatively, the sage is one who lives "according to an ideal which transcends the everyday."
Plato's theory of thesoul, which was inspired various by the teachings of Socrates, considered the psyche to be the essence of a person, being that which decides how people behave. Plato considered this essence to be an incorporeal, eternal occupant of a person's being. Plato said that even after death, the soul exists and is able to think. He believed that as bodies die, the soul is continually reborn (metempsychosis) in subsequent bodies. Plato divided the soul into three parts: the logistikon (reason), the thymoeides, and the epithymetikon.
Socrates was a Greek philosopher from Athens who is credited as the founder of Western philosophy and as among the first moral philosophers of the ethical tradition of thought. 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. He spent his last day in prison, refusing offers to help him escape.
Quis custodiet ipsos custodes? is a Latin phrase found in the Satires, a work of the 1st–2nd century Roman poet Juvenal. It may be translated as "Who will guard the guards themselves?" or "Who will watch the watchmen?".
