114-538: Plato ( / ˈ p l eɪ t oʊ / PLAY -toe ; Greek : Πλάτων, Plátōn , born c. 428-423 BC, died 348 BC), 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
228-484: A Platonist or Pythagorean, in that such a one would have "the viewpoint of logical simplicity as an indispensable and effective tool of his research." British philosopher Alfred N. Whitehead is often misquoted of uttering the famous saying of "All of Western philosophy is a footnote to Plato." Many recent philosophers have also diverged from what some would describe as ideals characteristic of traditional Platonism. Friedrich Nietzsche notoriously attacked Plato's "idea of

There are many English words of Greek origin . Greek is an independent branch of the Indo-European language family. The ancient language most closely related to it may be ancient Macedonian , which, by most accounts,
456-486: A belief in the immortality of the soul, and several dialogues end with long speeches imagining the afterlife . In the Timaeus , Socrates locates the parts of the soul within the human body: Reason is located in the head, spirit in the top third of the torso , and the appetite in the middle third of the torso, down to the navel . Furthermore, Plato evinces a belief in the theory of reincarnation in multiple dialogues (such as
570-400: A council of citizens was appointed as the "senate" of a city state or other political unit. The Greeks did not like the concept of monarchy, and as their democratic system fell, aristocracy was upheld. In his 1651 book Leviathan , Thomas Hobbes describes an aristocracy as a commonwealth in which the representative of the citizens is an assembly by part only. It is a system in which only
684-457: A descendant of two kings, Codrus and Melanthus . His mother was Perictione , descendant of Solon , a statesman credited with laying the foundations of Athenian democracy . Plato had two brothers, Glaucon and Adeimantus , a sister, Potone , and a half brother, Antiphon. Plato may have travelled to Italy, Sicily , Egypt, and Cyrene . At 40, he founded a school of philosophy, the Academy . It
798-485: A different doctrine with respect to Forms to Plato and Socrates. Aristotle suggests that Socrates' idea of forms can be discovered through investigation of the natural world, unlike Plato's Forms that exist beyond and outside the ordinary range of human understanding. The Socratic problem concerns how to reconcile these various accounts. The precise relationship between Plato and Socrates remains an area of contention among scholars. Although Socrates influenced Plato directly,
912-552: A fairly stable set of consonantal contrasts . The main phonological changes occurred during the Hellenistic and Roman period (see Koine Greek phonology for details): In all its stages, the morphology of Greek shows an extensive set of productive derivational affixes , a limited but productive system of compounding and a rich inflectional system. Although its morphological categories have been fairly stable over time, morphological changes are present throughout, particularly in
1026-556: A faster, more convenient cursive writing style with the use of ink and quill . The Greek alphabet consists of 24 letters, each with an uppercase ( majuscule ) and lowercase ( minuscule ) form. The letter sigma has an additional lowercase form (ς) used in the final position of a word: In addition to the letters, the Greek alphabet features a number of diacritical signs : three different accent marks ( acute , grave , and circumflex ), originally denoting different shapes of pitch accent on
1140-479: A fellow disciple of Plato. 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 Laërtius's reference to an account by Hermippus, a third-century Alexandrian. According to Tertullian , Plato simply died in his sleep. According to Philodemus, Plato
1254-557: A few people were capable or interested in following a reasoned philosophical discourse, but men in general are attracted by stories and tales. Consequently, then, he used the myth to convey the conclusions of the philosophical reasoning. Notable examples include the story of Atlantis , the Myth of Er , and the Allegory of the Cave . When considering the taxonomic definition of mankind , Plato proposed

According to one estimation, " Homeric Greek is probably closer to Demotic than 12-century Middle English is to modern spoken English ". Greek is spoken today by at least 13 million people, principally in Greece and Cyprus along with a sizable Greek-speaking minority in Albania near
1482-455: A geometrical example to expound Plato's view that knowledge in this latter sense is acquired by recollection. Socrates elicits a fact concerning a geometrical construction from a slave boy, who could not have otherwise known the fact (due to the slave boy's lack of education). The knowledge must be of, Socrates concludes, an eternal, non-perceptible Form. Plato also discusses several aspects of epistemology . In several dialogues, Socrates inverts
1596-472: A participant in any of the dialogues, and with the exception of the Apology , there is no suggestion that he heard any of the dialogues firsthand. Some dialogues have no narrator but have a pure "dramatic" form, some dialogues are narrated by Socrates himself, who speaks in the first person. The Symposium is narrated by Apollodorus, a Socratic disciple, apparently to Glaucon. Apollodorus assures his listener that he
1710-552: A powerful political force. The English Civil War involved the first sustained organised effort to reduce aristocratic power in Europe. In the 18th century, the rising merchant class attempted to use money to buy into the aristocracy, with some success. However, the French Revolution in the 1790s forced many French aristocrats into exile and caused consternation and shock in the aristocratic families of neighbouring countries. After
1824-439: A small part of the population represents the government; "certain men distinguished from the rest". Modern depictions of aristocracy tend to regard it not as the ancient Greek concept of rule by the best, but more as an oligarchy or plutocracy —rule by the few or the wealthy. The concept of aristocracy according to Plato has an ideal state ruled by the philosopher king . Plato describes "philosopher kings" as "those who love
1938-410: A system of checks and balances , where each element checks the excesses of the other. In modern times , aristocracy was usually seen as rule by a privileged group, the aristocratic class , and has since been contrasted with democracy . The concept evolved in ancient Greece in which a council of leading citizens was commonly empowered. That was contrasted with representative democracy in which
2052-418: A tripartite class structure corresponding to the appetite/spirit/reason structure of the individual soul. The appetite/spirit/reason are analogous to the castes of society. According to Socrates, a state made up of different kinds of souls will, overall, decline from an aristocracy (rule by the best) to a timocracy (rule by the honourable), then to an oligarchy (rule by the few), then to a democracy (rule by
2166-429: Is a nickname . According to Diogenes Laërtius, writing hundreds of years after Plato's death, his birth name was Aristocles ( Ἀριστοκλῆς ), meaning 'best reputation'. "Platon" sounds like "Platus" or "Platos", meaning "broad", and according to Diogenes' sources, Plato gained his nickname either from his wrestling coach, Ariston of Argos, who dubbed him "broad" on account of his chest and shoulders, or he gained it from
2280-749: Is already implicitly known, or at exposing the contradictions and muddles of an opponent's position." Karl Popper , on the other hand, claims that dialectic is the art of intuition for "visualising the divine originals, the Forms or Ideas, of unveiling the Great Mystery behind the common man's everyday world of appearances". During the early Renaissance, the Greek language and, along with it, Plato's texts were reintroduced to Western Europe by Byzantine scholars. Some 250 known manuscripts of Plato survive. In September or October 1484 Filippo Valori and Francesco Berlinghieri printed 1025 copies of Ficino's translation, using
2394-766: Is also found in Bulgaria near the Greek-Bulgarian border. Greek is also spoken worldwide by the sizable Greek diaspora which has notable communities in the United States , Australia , Canada , South Africa , Chile , Brazil , Argentina , Russia , Ukraine , the United Kingdom , and throughout the European Union , especially in Germany . Historically, significant Greek-speaking communities and regions were found throughout

The works of Plato were again revived at the times of Islamic Golden ages with other Greek contents through their translation from Greek to Arabic. Neoplatonism was revived from its founding father, Plotinus. Neoplatonism, a philosophical current that permeated Islamic scholarship, accentuated one facet of
2622-742: Is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to Greece , Cyprus , Italy (in Calabria and Salento ), southern Albania , and other regions of the Balkans , Caucasus , the Black Sea coast, Asia Minor , and the Eastern Mediterranean . It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system
2736-474: Is an Indo-European language, but also includes a number of borrowings from the languages of the populations that inhabited Greece before the arrival of Proto-Greeks, some documented in Mycenaean texts ; they include a large number of Greek toponyms . The form and meaning of many words have changed. Loanwords (words of foreign origin) have entered the language, mainly from Latin, Venetian , and Turkish . During
2850-495: Is by no means universally accepted, though Plato's works are still often characterized as falling at least roughly into three groups stylistically. Plato's unwritten doctrines are, according to some ancient sources, the most fundamental metaphysical teaching of Plato, which he disclosed only orally, and some say only to his most trusted fellows, and which he may have kept secret from the public, although many modern scholars doubt these claims. A reason for not revealing it to everyone

Plato's entire body of work is believed to have survived intact for over 2,400 years—unlike that of nearly all of his contemporaries. Although their popularity has fluctuated, they have consistently been read and studied through
3078-499: Is not in modern times understood in opposition to oligarchy or strictly as a form of government, with entitled nobility as in monarchies or aristocratic merchant republics . Its original classical understanding has been taken up by the modern concepts that can be loosely equivalent to meritocracy or technocracy . Aristocracies dominated political and economic power for most of the medieval and modern periods almost everywhere in Europe, using their wealth and land ownership to form
3192-496: Is partially discussed in Phaedrus where Plato criticizes the written transmission of knowledge as faulty, favouring instead the spoken logos : "he who has knowledge of the just and the good and beautiful ... will not, when in earnest, write them in ink, sowing them through a pen with words, which cannot defend themselves by argument and cannot teach the truth effectually." It is, however, said that Plato once disclosed this knowledge to
3306-510: Is protected and promoted officially as a regional and minority language in Armenia, Hungary , Romania, and Ukraine. It is recognized as a minority language and protected in Turkey by the 1923 Treaty of Lausanne . The phonology , morphology , syntax , and vocabulary of the language show both conservative and innovative tendencies across the entire attestation of the language from the ancient to
3420-411: Is recounting the story, which took place when he himself was an infant, not from his own memory, but as remembered by Aristodemus, who told him the story years ago. The Theaetetus is also a peculiar case: a dialogue in dramatic form embedded within another dialogue in dramatic form. Some scholars take this as an indication that Plato had by this date wearied of the narrated form. In most of the dialogues,

Greek roots have been widely used for centuries and continue to be widely used to coin new words in other languages; Greek and Latin are the predominant sources of international scientific vocabulary . Greek has been spoken in the Balkan peninsula since around
3762-758: Is still used internationally for the writing of Ancient Greek . In Greek, the question mark is written as the English semicolon, while the functions of the colon and semicolon are performed by a raised point (•), known as the ano teleia ( άνω τελεία ). In Greek the comma also functions as a silent letter in a handful of Greek words, principally distinguishing ό,τι ( ó,ti , 'whatever') from ότι ( óti , 'that'). Ancient Greek texts often used scriptio continua ('continuous writing'), which means that ancient authors and scribes would write word after word with no spaces or punctuation between words to differentiate or mark boundaries. Boustrophedon , or bi-directional text,
3876-630: Is the Greek alphabet , which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary . The alphabet arose from the Phoenician script and was in turn the basis of the Latin , Cyrillic , Coptic , Gothic , and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with
3990-477: Is virtue. In the Republic , Plato poses the question, "What is justice?" and by examining both individual justice and the justice that informs societies, Plato is able not only to inform metaphysics, but also ethics and politics with the question: "What is the basis of moral and social obligation?" Plato's well-known answer rests upon the fundamental responsibility to seek wisdom, wisdom which leads to an understanding of
4104-520: The Gorgias and his ambivalence toward rhetoric expressed in the Phaedrus . But other contemporary researchers contest the idea that Plato despised rhetoric and instead view his dialogues as a dramatization of complex rhetorical principles. Plato made abundant use of mythological narratives in his own work; It is generally agreed that the main purpose for Plato in using myths was didactic. He considered that only
4218-528: The Laws features Socrates, although many dialogues, including the Timaeus and Statesman , feature him speaking only rarely. Leo Strauss notes that Socrates' reputation for irony casts doubt on whether Plato's Socrates is expressing sincere beliefs. Xenophon 's Memorabilia and Aristophanes 's The Clouds seem to present a somewhat different portrait of Socrates from the one Plato paints. Aristotle attributes
4332-718: The Republic was prototypically totalitarian ; this has been disputed. Edmund Gettier famously demonstrated the Gettier problem for the justified true belief account of knowledge. That the modern theory of justified true belief as knowledge, which Gettier addresses, is equivalent to Plato's is, however, accepted only by some scholars but rejected by others.

He uses this idea of reincarnation to introduce the concept that knowledge is a matter of recollection of things acquainted with before one is born, and not of observation or study. Keeping with the theme of admitting his own ignorance, Socrates regularly complains of his forgetfulness. In the Meno , Socrates uses

4788-648: The Renaissance , George Gemistos Plethon brought Plato's original writings to Florence from Constantinople in the century of its fall. Many of the greatest early modern scientists and artists who broke with Scholasticism , with the support of the Plato-inspired Lorenzo (grandson of Cosimo), saw Plato's philosophy as the basis for progress in the arts and sciences. The 17th century Cambridge Platonists , sought to reconcile Plato's more problematic beliefs, such as metempsychosis and polyamory, with Christianity. By
4902-734: The Scholastic philosophers referred to Aristotle as "the Philosopher". The only Platonic work known to western scholarship was Timaeus , until translations were made after the fall of Constantinople , which occurred during 1453. However, the study of Plato continued in the Byzantine Empire , the Caliphates during the Islamic Golden Age , and Spain during the Golden age of Jewish culture . Plato

In the Sophist , Statesman , Republic , Timaeus , and the Parmenides , Plato associates knowledge with the apprehension of unchanging Forms and their relationships to one another (which he calls "expertise" in dialectic), including through
5130-455: The metaphysical tradition that strongly influenced Plato and continues today. Heraclitus viewed all things as continuously changing , that one cannot "step into the same river twice" due to the ever-changing waters flowing through it, and all things exist as a contraposition of opposites. According to Diogenes Laërtius, Plato received these ideas through Heraclitus' disciple Cratylus . Parmenides adopted an altogether contrary vision, arguing for
5244-492: The nominal and verbal systems. The major change in the nominal morphology since the classical stage was the disuse of the dative case (its functions being largely taken over by the genitive ). The verbal system has lost the infinitive , the synthetically -formed future, and perfect tenses and the optative mood . Many have been replaced by periphrastic ( analytical ) forms. Pronouns show distinctions in person (1st, 2nd, and 3rd), number (singular, dual , and plural in
5358-434: The "twin pillars of Platonism" as the theory of Forms, on the one hand, and, on the other hand, the doctrine of immortality of the soul. In the dialogues Socrates regularly asks for the meaning of a general term (e. g. justice, truth, beauty), and criticizes those who instead give him particular examples, rather than the quality shared by all examples. "Platonism" and its theory of Forms (also known as 'theory of Ideas') denies
5472-464: The 19th century, Plato's reputation was restored, and at least on par with Aristotle's. Plato's influence has been especially strong in mathematics and the sciences. Plato's resurgence further inspired some of the greatest advances in logic since Aristotle, primarily through Gottlob Frege . Albert Einstein suggested that the scientist who takes philosophy seriously would have to avoid systematization and take on many different roles, and possibly appear as
5586-570: The 1st century AD: Axiochus , Definitions , Demodocus , Epigrams , Eryxias , Halcyon , On Justice , On Virtue , Sisyphus . No one knows the exact order Plato's dialogues were written in, nor the extent to which some might have been later revised and rewritten. The works are usually grouped into Early (sometimes by some into Transitional ), Middle , and Late period; The following represents one relatively common division amongst developmentalist scholars. Whereas those classified as "early dialogues" often conclude in aporia ,
5700-465: The 3rd millennium BC, or possibly earlier. The earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the world's oldest recorded living language . Among the Indo-European languages, its date of earliest written attestation is matched only by the now-extinct Anatolian languages . The Greek language is conventionally divided into
5814-741: The Form of the Good. Plato views "The Good" as the supreme Form, somehow existing even "beyond being". In this manner, justice is obtained when knowledge of how to fulfill one's moral and political function in society is put into practice. The dialogues also discuss politics. Some of Plato's most famous doctrines are contained in the Republic as well as in the Laws and the Statesman . Because these opinions are not spoken directly by Plato and vary between dialogues, they cannot be straightforwardly assumed as representing Plato's own views. Socrates asserts that societies have

#17330852482835928-552: The Forms are the causes of everything else, he [i.e. Plato] supposed that their elements are the elements of all things. Accordingly, the material principle is the Great and Small [i.e. the Dyad], and the essence is the One ( τὸ ἕν ), since the numbers are derived from the Great and Small by participation in the One". "From this account it is clear that he only employed two causes: that of the essence, and
6042-606: The Forms were the truths of geometry , such as the Pythagorean theorem . The theory of Forms is first introduced in the Phaedo dialogue (also known as On the Soul ), wherein Socrates disputes the pluralism of Anaxagoras , then the most popular response to Heraclitus and Parmenides. For Plato, as was characteristic of ancient Greek philosophy, the soul was that which gave life. Plato advocates
6156-486: The Greek alphabet since approximately the 9th century BC. It was created by modifying the Phoenician alphabet , with the innovation of adopting certain letters to represent the vowels. The variant of the alphabet in use today is essentially the late Ionic variant, introduced for writing classical Attic in 403 BC. In classical Greek, as in classical Latin, only upper-case letters existed. The lower-case Greek letters were developed much later by medieval scribes to permit
6270-425: The Greek language are often emphasized. Although Greek has undergone morphological and phonological changes comparable to those seen in other languages, never since classical antiquity has its cultural, literary, and orthographic tradition been interrupted to the extent that one can speak of a new language emerging. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than
6384-491: The Greek language was the Cypriot syllabary (also a descendant of Linear A via the intermediate Cypro-Minoan syllabary ), which is closely related to Linear B but uses somewhat different syllabic conventions to represent phoneme sequences. The Cypriot syllabary is attested in Cyprus from the 11th century BC until its gradual abandonment in the late Classical period, in favor of the standard Greek alphabet. Greek has been written in
6498-629: The Greek verb have likewise remained largely the same over the course of the language's history but with significant changes in the number of distinctions within each category and their morphological expression. Greek verbs have synthetic inflectional forms for: Many aspects of the syntax of Greek have remained constant: verbs agree with their subject only, the use of the surviving cases is largely intact (nominative for subjects and predicates, accusative for objects of most verbs and many prepositions, genitive for possessors), articles precede nouns, adpositions are largely prepositional, relative clauses follow
6612-661: The Greek-Albanian border. A significant percentage of Albania's population has knowledge of the Greek language due in part to the Albanian wave of immigration to Greece in the 1980s and '90s and the Greek community in the country. Prior to the Greco-Turkish War and the resulting population exchange in 1923 a very large population of Greek-speakers also existed in Turkey , though very few remain today. A small Greek-speaking community
6726-545: The Qur’anic conception of God—the transcendent—while seemingly neglecting another—the creative. This philosophical tradition, introduced by Al-Farabi and subsequently elaborated upon by figures such as Avicenna , postulated that all phenomena emanated from the divine source. It functioned as a conduit, bridging the transcendental nature of the divine with the tangible reality of creation. In the Islamic context, Neoplatonism facilitated
6840-555: The Spartans conquered Aegina, or, alternatively, in 399 BC, immediately after the death of Socrates. After Dionysius's death, according to Plato's Seventh Letter , Dion requested Plato return to Syracuse to tutor Dionysius II , who seemed to accept Plato's teachings, but eventually became suspicious of their motives, expelling Dion and holding Plato against his will. Eventually Plato left Syracuse and Dion would return to overthrow Dionysius and rule Syracuse, before being usurped by Callippus ,

In modern times, Alfred North Whitehead famously said: "the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." There is a traditional story that Plato ( Ancient Greek : Πλάτων , Plátōn , from Ancient Greek : πλατύς , romanized : platys , lit. 'broad')

At the time of the word's origins in ancient Greece , the Greeks conceived it as rule by the best-qualified citizens—and often contrasted it favorably with monarchy , rule by an individual. The term
7410-542: The breadth of his eloquence, or his wide forehead. Philodemus , in extracts from the Herculaneum papyri , corroborates the claim that Plato was named for his "broad forehead". Seneca the Younger , writing hundreds of years after Plato's death, writes "His very name was given him because of his broad chest." According to the traditional story, Plato was originally named after his paternal grandfather, supposedly called Aristocles;
7524-477: The causation of good and of evil". The most important aspect of this interpretation of Plato's metaphysics is the continuity between his teaching and the Neoplatonic interpretation of Plotinus or Ficino which has been considered erroneous by many but may in fact have been directly influenced by oral transmission of Plato's doctrine. A modern scholar who recognized the importance of the unwritten doctrine of Plato

The works taken as genuine in antiquity but are now doubted by at least some modern scholars are: Alcibiades I (*), Alcibiades II (‡), Clitophon (*), Epinomis (‡), Letters (*), Hipparchus (‡), Menexenus (*), Minos (‡), Lovers (‡), Theages (‡) The following works were transmitted under Plato's name in antiquity, but were already considered spurious by
7752-484: The common man's intuition about what is knowable and what is real. Reality is unavailable to those who use their senses. Socrates says that he who sees with his eyes is blind. While most people take the objects of their senses to be real if anything is, Socrates is contemptuous of people who think that something has to be graspable in the hands to be real. In the Theaetetus , he says such people are eu amousoi (εὖ ἄμουσοι), an expression that means literally, "happily without

The modern standard complete English edition is the 1997 Hackett Plato: Complete Works , edited by John M. Cooper. Thirty-five dialogues and thirteen letters (the Epistles ) have traditionally been ascribed to Plato, though modern scholarship doubts the authenticity of at least some of these. Jowett mentions in his Appendix to Menexenus, that works which bore
7980-407: The concept of form as distinct from matter, and that the physical world is an imitation of an eternal mathematical world. These ideas were very influential on Heraclitus, Parmenides and Plato. The two philosophers Heraclitus and Parmenides , influenced by earlier pre-Socratic Greek philosophers such as Pythagoras and Xenophanes , departed from mythological explanations for the universe and began
8094-530: The corrupted form of democracy ( mob rule ). This belief was rooted in the assumption that the masses could only produce average policy, while the best of men could produce the best policy, if they were indeed the best of men. Later Polybius in his analysis of the Roman Constitution used the concept of aristocracy to describe his conception of a republic as a mixed form of government, along with democracy and monarchy in their conception from then, as

Beginning in Britain, industrialization in the 19th century brought urbanization, with wealth increasingly concentrated in the cities, which absorbed political power. However, as late as 1900, aristocrats maintained political dominance in Britain, Germany, Denmark, Sweden, Austria and Russia, but it

Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of the Christian Bible was also originally written in Greek. Together with the Latin texts and traditions of the Roman world , the Greek texts and Greek societies of antiquity constitute

( 10a ) In the Protagoras dialogue it is argued through Socrates that virtue is innate and cannot be learned, that no one does bad on purpose, and to know what is good results in doing what is good; that knowledge
8664-452: The following periods: In the modern era, the Greek language entered a state of diglossia : the coexistence of vernacular and archaizing written forms of the language. What came to be known as the Greek language question was a polarization between two competing varieties of Modern Greek: Dimotiki , the vernacular form of Modern Greek proper, and Katharevousa , meaning 'purified', a compromise between Dimotiki and Ancient Greek developed in

Martin Heidegger argued against Plato's alleged obfuscation of Being in his incomplete tome, Being and Time (1927). Karl Popper argued in the first volume of The Open Society and Its Enemies (1945) that Plato's proposal for a " utopian " political regime in
8892-766: The idea of a changeless, eternal universe and the view that change is an illusion. Plato's most self-critical dialogue is the Parmenides , which features Parmenides and his student Zeno , which criticizes Plato's own metaphysical theories. Plato's Sophist dialogue includes an Eleatic stranger. These ideas about change and permanence, or becoming and Being, influenced Plato in formulating his theory of Forms. In Plato's dialogues, Socrates and his company of disputants had something to say on many subjects, including several aspects of metaphysics . These include religion and science, human nature, love, and sexuality. More than one dialogue contrasts perception and reality , nature and custom, and body and soul. Francis Cornford identified
9006-439: The infinitive entirely (employing a raft of new periphrastic constructions instead) and uses participles more restrictively. The loss of the dative led to a rise of prepositional indirect objects (and the use of the genitive to directly mark these as well). Ancient Greek tended to be verb-final, but neutral word order in the modern language is VSO or SVO. Modern Greek inherits most of its vocabulary from Ancient Greek, which in turn
9120-533: The influence of Pythagoras , or in a broader sense, the Pythagoreans, such as Archytas also appears to have been significant. Aristotle and Cicero both claimed that the philosophy of Plato closely followed the teachings of the Pythagoreans . According to R. M. Hare , this influence consists of three points: Pythagoras held that all things are number, and the cosmos comes from numerical principles. He introduced
9234-438: The integration of Platonic philosophy with mystical Islamic thought, fostering a synthesis of ancient philosophical wisdom and religious insight. Inspired by Plato's Republic, Al-Farabi extended his inquiry beyond mere political theory, proposing an ideal city governed by philosopher-kings . Many of these commentaries on Plato were translated from Arabic into Latin and as such influenced Medieval scholastic philosophers. During
9348-463: The late 15th century BC, was the first script used to write Greek. It is basically a syllabary , which was finally deciphered by Michael Ventris and John Chadwick in the 1950s (its precursor, Linear A , has not been deciphered and most likely encodes a non-Greek language). The language of the Linear B texts, Mycenaean Greek , is the earliest known form of Greek. Another similar system used to write
9462-546: The material cause; for the Forms are the cause of the essence in everything else, and the One is the cause of it in the Forms. He also tells us what the material substrate is of which the Forms are predicated in the case of sensible things, and the One in that of the Forms ;– that it is this the duality (the Dyad, ἡ δυάς ), the Great and Small ( τὸ μέγα καὶ τὸ μικρόν ). Further, he assigned to these two elements respectively
9576-621: The membership of Greece and Cyprus in the European Union, Greek is one of the organization's 24 official languages . Greek is recognized as a minority language in Albania, and used co-officially in some of its municipalities, in the districts of Gjirokastër and Sarandë . It is also an official minority language in the regions of Apulia and Calabria in Italy. In the framework of the European Charter for Regional or Minority Languages , Greek
9690-441: The modern period. The division into conventional periods is, as with all such periodizations, relatively arbitrary, especially because, in all periods, Ancient Greek has enjoyed high prestige, and the literate borrowed heavily from it. Across its history, the syllabic structure of Greek has varied little: Greek shows a mixed syllable structure, permitting complex syllabic onsets but very restricted codas. It has only oral vowels and
9804-403: The muses". In other words, such people are willingly ignorant, living without divine inspiration and access to higher insights about reality. Many have interpreted Plato as stating – even having been the first to write – that knowledge is justified true belief , an influential view that informed future developments in epistemology. Plato also identified problems with
9918-476: The name "Plato" was only used as a nickname; and the philosopher could not have been named "Plato" because that name does not occur previously in his family line. Modern scholarship tends to reject the "Aristocles" story. Plato always called himself Platon . Platon was a fairly common name (31 instances are known from Athens alone), including people named before Plato was born. Robin Waterfield states that Plato
10032-399: The noun they modify and relative pronouns are clause-initial. However, the morphological changes also have their counterparts in the syntax, and there are also significant differences between the syntax of the ancient and that of the modern form of the language . Ancient Greek made great use of participial constructions and of constructions involving the infinitive, and the modern variety lacks
10146-463: The objects of study of the discipline of Classics . During antiquity , Greek was by far the most widely spoken lingua franca in the Mediterranean world . It eventually became the official language of the Byzantine Empire and developed into Medieval Greek . In its modern form , Greek is the official language of Greece and Cyprus and one of the 24 official languages of the European Union . It
10260-706: The older periods of Greek, loanwords into Greek acquired Greek inflections, thus leaving only a foreign root word. Modern borrowings (from the 20th century on), especially from French and English, are typically not inflected; other modern borrowings are derived from Albanian , South Slavic ( Macedonian / Bulgarian ) and Eastern Romance languages ( Aromanian and Megleno-Romanian ). Greek words have been widely borrowed into other languages, including English. Example words include: mathematics , physics , astronomy , democracy , philosophy , athletics , theatre, rhetoric , baptism , evangelist , etc. Moreover, Greek words and word elements continue to be productive as
10374-658: The other hand, if one derives one's account of something by way of the non-sensible Forms, because these Forms are unchanging, so too is the account derived from them. That apprehension of Forms is required for knowledge may be taken to cohere with Plato's theory in the Theaetetus and Meno . Indeed, the apprehension of Forms may be at the base of the account required for justification, in that it offers foundational knowledge which itself needs no account, thereby avoiding an infinite regression . Several dialogues discuss ethics including virtue and vice, pleasure and pain, crime and punishment, and justice and medicine. Socrates presents
10488-545: The people), and finally to tyranny (rule by one person, rule by a tyrant). Several dialogues tackle questions about art, including rhetoric and rhapsody. Socrates says that poetry is inspired by the muses , and is not rational. He speaks approvingly of this, and other forms of divine madness (drunkenness, eroticism, and dreaming) in the Phaedrus , and yet in the Republic wants to outlaw Homer's great poetry, and laughter as well. Scholars often view Plato's philosophy as at odds with rhetoric due to his criticisms of rhetoric in
10602-505: The polity. Hereditary rule in this understanding is more related to oligarchy , a corrupted form of aristocracy where there is rule by a few, but not by the best. Plato , Socrates , Aristotle, Xenophon , and the Spartans considered aristocracy (the ideal form of rule by the few) to be inherently better than the ideal form of rule by the many ( politeia ), but they also considered the corrupted form of aristocracy (oligarchy) to be worse than
10716-464: The primary speaker is Socrates, who employs a method of questioning which proceeds by a dialogue form called dialectic. The role of dialectic in Plato's thought is contested but there are two main interpretations: a type of reasoning and a method of intuition. Simon Blackburn adopts the first, saying that Plato's dialectic is "the process of eliciting the truth by means of questions aimed at opening out what
10830-574: The printing press [ it ] at the Dominican convent of San Jacopo di Ripoli [ it ] . The 1578 edition of Plato's complete works published by Henricus Stephanus ( Henri Estienne ) in Geneva also included parallel Latin translation and running commentary by Joannes Serranus ( Jean de Serres ). It was this edition which established standard Stephanus pagination , still in use today. The text of Plato as received today apparently represents
10944-419: The processes of collection and division . More explicitly, Plato himself argues in the Timaeus that knowledge is always proportionate to the realm from which it is gained. In other words, if one derives one's account of something experientially, because the world of sense is in flux, the views therein attained will be mere opinions. Meanwhile, opinions are characterized by a lack of necessity and stability. On
11058-608: The public in his lecture On the Good ( Περὶ τἀγαθοῦ ), in which the Good ( τὸ ἀγαθόν ) is identified with the One (the Unity, τὸ ἕν ), the fundamental ontological principle. The first witness who mentions its existence is Aristotle, who in his Physics writes: "It is true, indeed, that the account he gives there [i.e. in Timaeus ] of the participant is different from what he says in his so-called unwritten teachings ( Ancient Greek : ἄγραφα δόγματα , romanized : agrapha dogmata )." In Metaphysics he writes: "Now since
11172-695: The reality of the material world, considering it only an image or copy of the real world. According to this theory of Forms, there are these two kinds of things: the apparent world of material objects grasped by the senses, which constantly changes, and an unchanging and unseen world of Forms, grasped by reason ( λογική ). Plato's Forms represent types of things, as well as properties , patterns, and relations , which are referred to as objects. Just as individual tables, chairs, and cars refer to objects in this world, 'tableness', 'chairness', and 'carness', as well as e.g. justice , truth , and beauty refer to objects in another world. One of Plato's most cited examples for
11286-458: The sight of truth" ( Republic 475c) and supports the idea with the analogy of a captain and his ship or a doctor and his medicine. According to him, sailing and health are not things that everyone is qualified to practice by nature. A large part of the Republic then addresses how the educational system should be set up to produce philosopher kings. In contrast to its original conceptual drawing by Aristotle in classical antiquity , aristocracy
11400-455: The so-called "middle dialogues" provide more clearly stated positive teachings that are often ascribed to Plato such as the theory of Forms. The remaining dialogues are classified as "late" and are generally agreed to be difficult and challenging pieces of philosophy. It should, however, be kept in mind that many of the positions in the ordering are still highly disputed, and also that the very notion that Plato's dialogues can or should be "ordered"
11514-437: The stressed vowel; the so-called breathing marks ( rough and smooth breathing ), originally used to signal presence or absence of word-initial /h/; and the diaeresis , used to mark the full syllabic value of a vowel that would otherwise be read as part of a diphthong. These marks were introduced during the course of the Hellenistic period. Actual usage of the grave in handwriting saw a rapid decline in favor of uniform usage of
11628-486: The term "featherless biped", and later ζῷον πολιτικόν ( zōon politikon ), a "political" or "state-building" animal ( Aristotle 's term, based on Plato's Statesman ). Diogenes the Cynic took issue with the former definition, reportedly producing a recently plucked chicken with the exclamation of "Here is Plato’s man!" (variously translated as "Behold, a man!"; "Here is a human!" etc.). Plato never presents himself as
11742-412: The tyrant Dionysius , with Dionysius's brother-in-law, Dion of Syracuse , whom Plato had recruited as one of his followers, but the tyrant himself turned against Plato. Plato almost faced death, but was sold into slavery. Anniceris , a Cyrenaic philosopher, bought Plato's freedom for twenty minas , and sent him home. Philodemus however states that Plato was sold as a slave as early as in 404 BC, when
11856-484: Was Heinrich Gomperz who described it in his speech during the 7th International Congress of Philosophy in 1930. All the sources related to the ἄγραφα δόγματα have been collected by Konrad Gaiser and published as Testimonia Platonica . Plato's thought is often compared with that of his most famous student, Aristotle , whose reputation during the Western Middle Ages so completely eclipsed that of Plato that
11970-568: Was a distinct dialect of Greek itself. Aside from the Macedonian question, current consensus regards Phrygian as the closest relative of Greek, since they share a number of phonological, morphological and lexical isoglosses , with some being exclusive between them. Scholars have proposed a Graeco-Phrygian subgroup out of which Greek and Phrygian originated. Among living languages, some Indo-Europeanists suggest that Greek may be most closely related to Armenian (see Graeco-Armenian ) or
12084-549: Was also used as the official language of government and religion in the Christian Nubian kingdoms , for most of their history. Greek, in its modern form, is the official language of Greece, where it is spoken by almost the entire population. It is also the official language of Cyprus (nominally alongside Turkish ) and the British Overseas Territory of Akrotiri and Dhekelia (alongside English ). Because of
12198-546: Was also used in Ancient Greek. Greek has occasionally been written in the Latin script , especially in areas under Venetian rule or by Greek Catholics . The term Frankolevantinika / Φραγκολεβαντίνικα applies when the Latin script is used to write Greek in the cultural ambit of Catholicism (because Frankos / Φράγκος is an older Greek term for West-European dating to when most of (Roman Catholic Christian) West Europe
12312-607: Was buried in the garden of his academy in Athens, close to the sacred shrine of the Muses. In 2024, a scroll found at Herculaneum was deciphered, that confirmed some previous theories. The papyrus says that before death Plato "retained enough lucidity to critique the musician for her lack of rhythm", and that he was buried "in his designated garden in the Academy of Athens". Plato never speaks in his own voice in his dialogues ; every dialogue except
12426-416: Was first used by such ancient Greeks as Aristotle and Plato , who used it to describe a system where only the best of the citizens, chosen through a careful process of selection, would become rulers, and hereditary rule would actually have been forbidden, unless the rulers' children performed best and were better endowed with the attributes that make a person fit to rule compared with every other citizen in
12540-483: Was located in Athens, on a plot of land in the Grove of Hecademus or Academus , named after an Attic hero in Greek mythology . The Academy operated until it was destroyed by Sulla in 84 BC. Many philosophers studied at the Academy, the most prominent being Aristotle. According to Diogenes Laërtius , throughout his later life, Plato became entangled with the politics of the city of Syracuse , where he attempted to replace
12654-468: Was not a nickname, but a perfectly normal name, and "the common practice of naming a son after his grandfather was reserved for the eldest son", not Plato. According to Debra Nails, Plato's grandfather was the Aristocles who was archon in 605/4. Plato was born in Athens or Aegina , between 428 and 423 BC. He was a member of an aristocratic and influential family. His father was Ariston, who may have been
12768-565: Was the founder of the Platonic Academy , a philosophical school in Athens where Plato taught the doctrines that would later become known as Platonism . Plato's most famous contribution is the theory of forms (or ideas) , which has been interpreted as advancing a solution to what is now known as the problem of universals . He was decisively influenced by the pre-Socratic thinkers Pythagoras , Heraclitus , and Parmenides , although much of what
12882-566: Was under the control of the Frankish Empire ). Frankochiotika / Φραγκοχιώτικα (meaning 'Catholic Chiot') alludes to the significant presence of Catholic missionaries based on the island of Chios . Additionally, the term Greeklish is often used when the Greek language is written in a Latin script in online communications. The Latin script is nowadays used by the Greek-speaking communities of Southern Italy . The Yevanic dialect
12996-653: Was written by Romaniote and Constantinopolitan Karaite Jews using the Hebrew Alphabet . In a tradition, that in modern time, has come to be known as Greek Aljamiado , some Greek Muslims from Crete wrote their Cretan Greek in the Arabic alphabet . The same happened among Epirote Muslims in Ioannina . This also happened among Arabic-speaking Byzantine rite Christians in the Levant ( Lebanon , Palestine, and Syria ). This usage
