Dialectic in the context of "Truth"

Plato (/ˈpleɪtoʊ/ PLAY-toe; Greek: Πλάτων, Plátōn; born c. 428–423 BC, died 348/347 BC) was an ancient Greek philosopher of Classical Athens who is most commonly considered the foundational thinker of the Western philosophical tradition. An innovator of the literary dialogue and dialectic forms, Plato influenced all the major areas of theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the collection of philosophical theories that would later become known as Platonism.

Plato's most famous contribution is his Theory of Forms (or Ideas), which aims to solve what is now known as the problem of universals. He was influenced by the pre-Socratic thinkers Pythagoras, Heraclitus, and Parmenides, although much of what is known about them is derived from Plato himself.

Rhetoric is the art of persuasion. It is one of the three ancient arts of discourse (trivium) along with grammar and logic/dialectic. As an academic discipline within the humanities, rhetoric aims to study the techniques that speakers or writers use to inform, persuade, and motivate their audiences. Rhetoric also provides heuristics for understanding, discovering, and developing arguments for particular situations.

Aristotle defined rhetoric as "the faculty of observing in any given case the available means of persuasion", and since mastery of the art was necessary for victory in a case at law, for passage of proposals in the assembly, or for fame as a speaker in civic ceremonies, he called it "a combination of the science of logic and of the ethical branch of politics". Aristotle also identified three persuasive audience appeals: logos, pathos, and ethos. The five canons of rhetoric, or phases of developing a persuasive speech, were first codified in classical Rome: invention, arrangement, style, memory, and delivery.

The Socratic method (also known as Socratic debate, the Socratic dialectic, or the method of Elenchus) is a form of argumentative dialogue in which an individual probes a conversation partner on a topic with questions and clarifications, until the partner is pressed to come to a conclusion on their own, or else their reasoning breaks down and they are forced to admit ignorance. Socratic dialogues between characters employing this method feature in many of the works of the ancient Greek philosopher Plato, where a fictionalized version of his real-life teacher Socrates debates various philosophical issues with a partner.

In Plato's dialogue "Theaetetus", Socrates describes his method as a form of "midwifery" because it is employed to help his interlocutors develop their understanding in a way analogous to a child developing in the womb. The Socratic method begins with commonly held beliefs and scrutinizes them by way of questioning to determine their internal consistency and their coherence with other beliefs and so to bring everyone closer to the truth.

An argument is one or more premises—sentences, statements, or propositions—directed towards arriving at a logical conclusion. The purpose of an argument is to give reasons for one's thinking and understanding via justification, explanation, or persuasion. As a series of logical steps, arguments are intended to determine or show the degree of truth or acceptability of a logical conclusion.

The process of crafting or delivering arguments, argumentation, can be studied from three main perspectives: through the logical, the dialectical and the rhetorical perspective.

Argumentation theory is the interdisciplinary study of how conclusions can be supported or undermined by premises through logical reasoning. With historical origins in logic, dialectic, and rhetoric, argumentation theory includes the arts and sciences of civil debate, dialogue, conversation, and persuasion. It studies rules of inference, logic, and procedural rules in both artificial and real-world settings.

Argumentation includes various forms of dialogue such as deliberation and negotiation which are concerned with collaborative decision-making procedures. It also encompasses eristic dialogue, the branch of social debate in which victory over an opponent is the primary goal, and didactic dialogue used for teaching. This discipline also studies the means by which people can express and rationally resolve or at least manage their disagreements.

The lord–bondsman dialectic (German: Herrschaft und Knechtschaft; also translated master–servant dialectic) is a famous passage in Georg Wilhelm Friedrich Hegel's The Phenomenology of Spirit. It is widely considered a key element in Hegel's philosophical system, and it has heavily influenced many subsequent philosophers.

The passage describes, in narrative form, the development of self-consciousness as such in an encounter between what are thereby (i.e., emerging only from this encounter) two distinct, self-conscious beings. The essence of the dialectic is the movement or motion of recognizing, in which the two self-consciousnesses are constituted in each being recognized as self-conscious by the other. This movement, inexorably taken to its extreme, takes the form of a "struggle to the death" in which one masters [beherrscht] the other, only to find that such lordship makes the very recognition he had sought impossible, since the bondsman, in this state, is not free to offer it.

Theodor W. Adorno (/əˈdɔːrnoʊ/ ə-DOR-noh; German: [ˈteːodoːɐ̯ aˈdɔʁno] ; born Theodor Ludwig Wiesengrund; 11 September 1903 – 6 August 1969) was a German philosopher, musicologist, and social theorist. He was a leading member of the Frankfurt School of critical theory, whose work has come to be associated with thinkers such as Ernst Bloch, Walter Benjamin, Max Horkheimer, Erich Fromm, and Herbert Marcuse, for whom the works of Sigmund Freud, Karl Marx, and G. W. F. Hegel were essential to a critique of modern society. As a critic of both fascism and what he called the culture industry, his writings—such as Dialectic of Enlightenment (1947), Minima Moralia (1951), and Negative Dialectics (1966)—strongly influenced the European New Left.

In an intellectual climate shaped by existentialism and logical positivism, Adorno developed a dialectical conception of history and philosophy that challenged the foundations of both, anticipating the divide that would later emerge between the analytic and continental traditions. As a classically trained musician, Adorno studied composition with Alban Berg of the Second Viennese School, influenced by his early admiration for the music of Arnold Schoenberg. Adorno's commitment to avant-garde music formed the backdrop of his subsequent writings and led to his collaboration with Thomas Mann on the latter's novel Doctor Faustus (1947), while the two men lived in California as exiles during the Second World War. Working at the newly relocated Institute for Social Research, Adorno collaborated on influential studies of authoritarianism, antisemitism, and propaganda that would later serve as models for sociological studies the institute carried out in post-war Germany.
