Socrates in the context of "Pre-Socratic philosopher"

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.

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.

Ontology is the philosophical study of being. It is traditionally understood as the subdiscipline of metaphysics focused on the most general features of reality. As one of the most fundamental concepts, being encompasses all of reality and every entity within it. To articulate the basic structure of being, ontology examines the commonalities among all things and investigates their classification into basic types, such as the categories of particulars and universals. Particulars are unique, non-repeatable entities, such as the person Socrates, whereas universals are general, repeatable entities, like the color green. Another distinction exists between concrete objects existing in space and time, such as a tree, and abstract objects existing outside space and time, like the number 7. Systems of categories aim to provide a comprehensive inventory of reality by employing categories such as substance, property, relation, state of affairs, and event.

Ontologists disagree regarding which entities exist at the most basic level. Platonic realism asserts that universals have objective existence, while conceptualism maintains that universals exist only in the mind, and nominalism denies their existence altogether. Similar disputes pertain to mathematical objects, unobservable objects assumed by scientific theories, and moral facts. Materialism posits that fundamentally only matter exists, whereas dualism asserts that mind and matter are independent principles. According to some ontologists, objective answers to ontological questions do not exist, with perspectives shaped by differing linguistic practices.

Pre-Socratic philosophy, also known as early Greek philosophy, is ancient Greek philosophy before Socrates. Pre-Socratic philosophers were mostly interested in cosmology, the beginning and the substance of the universe, but the inquiries of these early philosophers spanned the workings of the natural world as well as human society, ethics, and religion. They sought explanations based on natural law rather than the actions of gods. Their work and writing has been almost entirely lost. Knowledge of their views comes from testimonia, i.e. later authors' discussions of the work of pre-Socratics. Philosophy found fertile ground in the ancient Greek world because of the close ties with neighboring civilizations and the rise of autonomous civil entities, poleis.

Pre-Socratic philosophy began in the 6th century BC with the three Milesians: Thales, Anaximander, and Anaximenes. They all attributed the arche (a word that could take the meaning of "origin", "substance" or "principle") of the world to, respectively, water, apeiron (the unlimited), and air. Another three pre-Socratic philosophers came from nearby Ionian towns: Xenophanes, Heraclitus, and Pythagoras. Xenophanes is known for his critique of the anthropomorphism of gods. Heraclitus, who was notoriously difficult to understand, is known for his maxim on impermanence, ta panta rhei, and for attributing fire to be the arche of the world. Pythagoras created a cult-like following that advocated that the universe was made up of numbers. The Eleatic school (Parmenides, Zeno of Elea, and Melissus) followed in the 5th century BC. Parmenides claimed that only one thing exists and nothing can change. Zeno and Melissus mainly defended Parmenides' opinion. Anaxagoras and Empedocles offered a pluralistic account of how the universe was created. Leucippus and Democritus are known for their atomism, and their views that only void and matter exist. The Sophists advanced philosophical relativism. The Pre-Socratics have had significant impact on several concepts of Western philosophy, such as naturalism and rationalism, and paved the way for scientific methodology.

Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and "Socrates is a man" to the conclusion "Socrates is mortal" is deductively valid. An argument is sound if it is valid and all its premises are true. One approach defines deduction in terms of the intentions of the author: they have to intend for the premises to offer deductive support to the conclusion. With the help of this modification, it is possible to distinguish valid from invalid deductive reasoning: it is invalid if the author's belief about the deductive support is false, but even invalid deductive reasoning is a form of deductive reasoning.

Deductive logic studies under what conditions an argument is valid. According to the semantic approach, an argument is valid if there is no possible interpretation of the argument whereby its premises are true and its conclusion is false. The syntactic approach, by contrast, focuses on rules of inference, that is, schemas of drawing a conclusion from a set of premises based only on their logical form. There are various rules of inference, such as modus ponens and modus tollens. Invalid deductive arguments, which do not follow a rule of inference, are called formal fallacies. Rules of inference are definitory rules and contrast with strategic rules, which specify what inferences one needs to draw in order to arrive at an intended conclusion.

Ancient Greek literature is literature written in the Ancient Greek language from the earliest texts until the time of the Byzantine Empire. The earliest surviving works of ancient Greek literature, dating back to the early Archaic period, are the two epic poems the Iliad and the Odyssey, set in an idealized archaic past today identified as having some relation to the Mycenaean era. These two epics, along with the Homeric Hymns and the two poems of Hesiod, the Theogony and Works and Days, constituted the major foundations of the Greek literary tradition that would continue into the Classical, Hellenistic, and Roman periods.

The lyric poets Sappho, Alcaeus, and Pindar were highly influential during the early development of the Greek poetic tradition. Aeschylus is the earliest Greek tragic playwright for whom any plays have survived complete. Sophocles is famous for his tragedies about Oedipus, particularly Oedipus the King and Antigone. Euripides is known for his plays which often pushed the boundaries of the tragic genre. The comedic playwright Aristophanes wrote in the genre of Old Comedy, while the later playwright Menander was an early pioneer of New Comedy. The historians Herodotus of Halicarnassus and Thucydides, who both lived during the fifth century BC, wrote accounts of events that happened shortly before and during their own lifetimes. The philosopher Plato wrote dialogues, usually centered around his teacher Socrates, dealing with various philosophical subjects, whereas his student Aristotle wrote numerous treatises, which later became highly influential.

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.

Many histories of Western political thought trace its origins to ancient Greece (specifically to Athenian democracy and Ancient Greek philosophy). The political philosophy of thinkers such as Socrates, Plato, and Aristotle are traditionally elevated as exceptionally important and influential in such works.

An intellectual is a person who engages in critical thinking, research, and reflection about the nature of reality, especially the nature of society and proposed solutions for its normative problems. Coming from the world of culture, either as a creator or as a mediator, the intellectual participates in politics, either to defend a concrete proposition or to denounce an injustice, usually by either rejecting, producing or extending an ideology, and by defending a system of values.
