(literally, "refutation, scrutiny") whereby a series of questions clarifies a more precise statement of a vague belief, logical consequences of that statement are explored, and a contradiction is discovered. The method is largely destructive, in that false belief is exposed and only constructive in that this exposure may lead to further search for truth. The detection of error does not amount to a proof of the antithesis; for example, a contradiction in the consequences of a definition of ''piety'' does not provide a correct definition. The principal aim of Socratic activity may be to improve the soul of the interlocutors, by freeing them from unrecognized errors; or indeed, by teaching them the spirit of inquiry. In common cases, Socrates used

'', Socrates asks

to provide a definition of piety. Euthyphro replies that the pious is that which is loved by the gods. But, Socrates also has Euthyphro agreeing that the gods are quarrelsome and their quarrels, like human quarrels, concern objects of love or hatred. Therefore, Socrates reasons, at least one thing exists that certain gods love but other gods hate. Again, Euthyphro agrees. Socrates concludes that if Euthyphro's definition of piety is acceptable, then there must exist at least one thing that is both pious and impious (as it is both loved and hated by the gods)—which Euthyphro admits is absurd. Thus, Euthyphro is brought to a realization by this dialectical method that his definition of piety is not sufficiently meaningful. In another example, in Plato's Gorgias, dialectic occurs between Socrates, the Sophist Gorgias, and two men, Polus and Callicles. Because Socrates' ultimate goal was to reach true knowledge, he was even willing to change his own views in order to arrive at the truth. The fundamental goal of dialectic, in this instance, was to establish a precise definition of the subject (in this case, rhetoric) and with the use of argumentation and questioning, make the subject even more precise. In the Gorgias, Socrates reaches the truth by asking a series of questions and in return, receiving short, clear answers.

Plato

There is another interpretation of dialectic, suggested in ''The Republic'', as a procedure that is both discursive and intuitive. In Platonism and Neoplatonism, dialectic assumes an ontological and metaphysical role in that it becomes the process whereby the intellect passes from sensibles to intelligibles, rising from Idea to Idea until it finally grasps the supreme Idea, the First Principle which is the origin of all. The philosopher is consequently a "dialectician". In this sense, dialectic is a process of enquiry that does away with hypotheses up to the First Principle (''Republic'', VII, 533 c-d). It slowly embraces the multiplicity in unity. Simon Blackburn writes that the dialectic in this sense is used to understand "the total process of enlightenment, whereby the philosopher is educated so as to achieve knowledge of the supreme good, the Form of the Good".

Aristotle

Aristotle stresses that rhetoric is closely related to dialectic. He offers several formulas to describe this affinity between the two disciplines: first of all, rhetoric is said to be a "counterpart" (antistrophos) to dialectic (Rhet. I.1, 1354a1); (ii) it is also called an "outgrowth" (paraphues ti) of dialectic and the study of character (Rhet. I.2, 1356a25f.); finally, Aristotle says that rhetoric is part of dialectic and resembles it (Rhet. I.2, 1356a30f.). In saying that rhetoric is a counterpart to dialectic, Aristotle obviously alludes to Plato's Gorgias (464bff.), where rhetoric is ironically defined as a counterpart to cookery in the soul. Since, in this passage, Plato uses the word 'antistrophos' to designate an analogy, it is likely that Aristotle wants to express a kind of analogy too: what dialectic is for the (private or academic) practice of attacking and maintaining an argument, rhetoric is for the (public) practice of defending oneself or accusing an opponent. The analogy to dialectic has important implications for the status of rhetoric. Plato argued in his Gorgias that rhetoric cannot be an art (technê), since it is not related to a definite subject, while real arts are defined by their specific subjects, as e.g. medicine or shoemaking are defined by their products, i.e., health and shoes.

Hegelian dialectic

Hegelian dialectic, usually presented in a threefold manner, was stated by Heinrich Moritz Chalybäus as comprising three dialectical stages of development: a thesis, giving rise to its reaction; an antithesis, which contradicts or negates the thesis; and the tension between the two being resolved by means of a synthesis. Although this model is often named after Hegel, he never used that specific formulation. Hegel ascribed that terminology to Kant. Carrying on Kant's work,

Fichte Johann Gottlieb Fichte (; ; 19 May 1762 – 29 January 1814) was a German philosopher who became a founding figure of the philosophical movement known as German idealism, which developed from the theoretical and ethical writings of Immanuel Ka ...

greatly elaborated on the synthesis model and popularized it. On the other hand, Hegel did use a three-valued logical model that is very similar to the antithesis model, but Hegel's most usual terms were: Abstract-Negative-Concrete. Hegel used this writing model as a backbone to accompany his points in many of his works. The formula, thesis-antithesis-synthesis, does not explain why the thesis requires an antithesis. However, the formula, abstract-negative-concrete, suggests a flaw, or perhaps an incompleteness, in any initial thesis—it is too abstract and lacks the negative of trial, error, and experience. For Hegel, the concrete, the synthesis, the absolute, must always pass through the phase of the negative, in the journey to completion, that is, mediation. This is the essence of what is popularly called Hegelian dialectics. According to the German philosopher Walter Kaufmann:

Fichte introduced into German philosophy the three-step of thesis, antithesis, and synthesis, using these three terms. Schelling took up this terminology. ''Hegel did not.'' He never once used these three terms together to designate three stages in an argument or account in any of his books. And they do not help us understand his ''Phenomenology'', his ''Logic'', or his philosophy of history; they impede any open-minded comprehension of what he does by forcing it into a scheme which was available to him and which he deliberately spurned ..The mechanical formalism ..Hegel derides expressly and at some length in the preface to the ''Phenomenology''.

Kaufmann also cites Hegel's criticism of the triad model commonly misattributed to him, adding that "the only place where Hegel uses the three terms together occurs in his lectures on the history of philosophy, on the last page but one of the sections on Kant—where Hegel roundly reproaches Kant for having 'everywhere posited thesis, antithesis, synthesis'". To describe the activity of overcoming the negative, Hegel also often used the term ''Aufhebung'', variously translated into English as "sublation" or "overcoming", to conceive of the working of the dialectic. Roughly, the term indicates preserving the useful portion of an idea, thing, society, etc., while moving beyond its limitations. ( Jacques Derrida's preferred French translation of the term was ''relever''.) In the ''Logic'', for instance, Hegel describes a dialectic of

existence Existence is the ability of an entity to interact with reality. In philosophy, it refers to the ontological property of being. Etymology The term ''existence'' comes from Old French ''existence'', from Medieval Latin ''existentia/exsistentia' ...

: first, existence must be posited as pure Being (''Sein''); but pure Being, upon examination, is found to be indistinguishable from Nothing (''Nichts''). When it is realized that what is coming into being is, at the same time, also returning to nothing (in life, for example, one's living is also a dying), both Being and Nothing are united as Becoming. As in the Socratic dialectic, Hegel claimed to proceed by making implicit contradictions explicit: each stage of the process is the product of contradictions inherent or implicit in the preceding stage. For Hegel, the whole of history is one tremendous dialectic, major stages of which chart a progression from self-alienation as

of free and equal citizens. The Hegelian dialectic cannot be mechanically applied for any chosen thesis. Critics argue that the selection of any antithesis, other than the logical negation of the thesis, is subjective. Then, if the logical negation is used as the antithesis, there is no rigorous way to derive a synthesis. In practice, when an antithesis is selected to suit the user's subjective purpose, the resulting "contradictions" are rhetorical, not logical, and the resulting synthesis is not rigorously defensible against a multitude of other possible syntheses. The problem with the Fichtean "thesis–antithesis–synthesis" model is that it implies that contradictions or negations come from outside of things. Hegel's point is that they are inherent in and internal to things. This conception of dialectics derives ultimately from

Heraclitus Heraclitus of Ephesus (; grc-gre, Ἡράκλειτος , "Glory of Hera"; ) was an ancient Greek pre-Socratic philosopher from the city of Ephesus, which was then part of the Persian Empire. Little is known of Heraclitus's life. He wrot ...

. Hegel stated that the purpose of dialectics is "to study things in their own being and movement and thus to demonstrate the finitude of the partial categories of understanding." One important dialectical principle for Hegel is the transition from quantity to quality, which he terms the Measure. The measure is the qualitative quantum, the quantum is the existence of quantity. As an example, Hegel mentions the states of aggregation of water: "Thus the temperature of water is, in the first place, a point of no consequence in respect of its liquidity: still with the increase or diminution of the temperature of the liquid water, there comes a point where this state of cohesion suffers a qualitative change, and the water is converted into steam or ice". As other examples Hegel mentions the reaching of a point where a single additional grain makes a heap of wheat; or where the bald tail is produced, if we continue plucking out single hairs. Another important principle for Hegel is the negation of the negation, which he also terms ''Aufhebung'' (sublation): Something is only what it is in its relation to another, but by the negation of the negation this something incorporates the other into itself. The dialectical movement involves two moments that negate each other, something and its other. As a result of the negation of the negation, "something becomes its other; this other is itself something; therefore it likewise becomes an other, and so on ad infinitum". Something in its passage into other only joins with itself, it is self-related. In becoming there are two moments: coming-to-be and ceasing-to-be: by sublation, i.e., negation of the negation, being passes over into nothing, it ceases to be, but something new shows up, is coming to be. What is sublated (''aufgehoben'') on the one hand ceases to be and is put to an end, but on the other hand it is preserved and maintained. In dialectics, a totality transforms itself; it is self-related, then self-forgetful, relieving the original tension.

For Lenin, the primary feature of Marx's "dialectical materialism" (Lenin's term) was its application of materialist philosophy to history and social sciences. Lenin's main input in the philosophy of dialectical materialism was his theory of reflection, which presented human consciousness as a dynamic reflection of the objective material world that fully shapes its contents and structure. Later, Stalin's works on the subject established a rigid and formalistic division of Marxist–Leninist theory in the dialectical materialism and historical materialism parts. While the first was supposed to be the key method and theory of the philosophy of nature, the second was the Soviet version of the philosophy of history.

(1899–1966), even though Barth himself expressed his unease in the use of the term. In dialectical theology the difference and opposition between God and human beings is stressed in such a way that all human attempts at overcoming this opposition through moral, religious or philosophical idealism must be characterized as 'sin'. In the death of Christ humanity is negated and overcome, but this judgment also points forwards to the resurrection in which humanity is reestablished in Christ. For Barth this meant that only through God's 'no' to everything human can his 'yes' be perceived. Applied to traditional themes of Protestant theology, such as

''. For Lonergan, dialectic is both individual and operative in community. Simply described, it is a dynamic process that results in something new: Dialectic is one of the eight functional specialties Lonergan envisaged for theology to bring this discipline into the modern world. Lonergan believed that the lack of an agreed method among scholars had inhibited substantive agreement from being reached and progress from being made compared to the natural sciences.

Criticisms

Karl Popper has attacked the dialectic repeatedly. In 1937, he wrote and delivered a paper entitled "What Is Dialectic?" in which he attacked the dialectical method for its willingness "to put up with contradictions". Popper concluded the essay with these words: "The whole development of dialectic should be a warning against the dangers inherent in philosophical system-building. It should remind us that

should not be made a basis for any sort of scientific system and that philosophers should be much more modest in their claims. One task which they can fulfill quite usefully is the study of the critical methods of science" (Ibid., p. 335). In chapter 12 of volume 2 of ''
