Dialectic

From Wikipedia, the free encyclopedia

Dialectic (also called dialectics or the dialectical method) is a method of argument, which has been central to both Eastern and Western philosophy since ancient times. The word "dialectic" originates in Ancient Greece, and was made popular by Plato's Socratic dialogues. Dialectic is rooted in the ordinary practice of a dialogue between two or more people who hold different ideas and wish to persuade each other. The presupposition of a dialectical argument is that the participants, even if they do not agree, share at least some meanings and principles of inference. Different forms of dialectical reason have emerged in the East and in the West, as well as during different eras of history (see below). Among the major forms of dialectic reason are Socratic, Hindu, Buddhist, Medieval, Hegelian, Marxist, and Talmudic.

Theoretical principles

Dialectics is based around three (or four) basic concepts:

1. Everything is transient and finite, existing in the medium of time (this idea is not accepted by some dialecticians).
2. Everything is made out of opposing forces/opposing sides (contradictions).
3. Gradual changes lead to turning points, where one force overcomes the other (quantitative change leads to qualitative change).
4. Change moves in spirals (or helices), not circles. (Sometimes referred to as "negation of the negation")

Within this broad qualification, dialectics has a rich and varied history. It has been stated that the history of dialectic is identical to the extensive history of philosophy.[1] The basic idea is perhaps already present in Heraclitus of Ephesus, who held that all is in constant change, as a result of inner strife and opposition.[2][3][4] Only fragments of his works and commentary remain, however.

The aim of the dialectical method is resolution of the disagreement through rational discussion,[5][6] and ultimately the search for truth. One way to proceed — the Socratic method — is to show that a given hypothesis (with other admissions) leads to a contradiction; thus, forcing the withdrawal of the hypothesis as a candidate for truth (see also reductio ad absurdum). Another way of trying to resolve a disagreement is by denying some presupposition of both the contending thesis and antithesis; thereby moving to a third (syn)thesis or "sublation". However, the rejection of the participant's presuppositions can be resisted, which might generate a second-order controversy.[7]

Western forms

Classical philosophy

The term "dialectic" owes much of its prestige to its role in the philosophy of Socrates and Plato. According to Aristotle,[8] it was Zeno of Elea who 'invented' dialectic.

In classical philosophy, dialectic (Greek: διαλεκτική) is a form of reasoning based on the exchange of arguments and counter-arguments, advocating propositions (theses) and counter-propositions (antitheses). The outcome of such an exchange might be the refutation of one of the relevant points of view, or a synthesis or combination of the opposing assertions, or at least a qualitative transformation in the direction of the dialogue.[9][10]

Socratic dialectic

In Plato's dialogues and other Socratic dialogues, Socrates attempts to examine someone's beliefs, at times even first principles or premises by which we all reason and argue. Socrates typically argues by cross-examining his interlocutor's claims and premises in order to draw out a contradiction or inconsistency among them. According to Plato, the rational detection of error amounts to finding the proof of the antithesis.[11] However, important as this objective is, the principal aim of Socratic activity seems to be to improve the soul of his interlocutors, by freeing them from unrecognized errors.

For example, in the Euthyphro, Socrates asks Euthyphro 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 which 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 which 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.

Medieval philosophy

Dialectics (also called logic) was one of the three liberal arts taught in Medieval universities as part of the trivium. The trivium also included rhetoric and grammar.[12][13][14][15]

Modern philosophy

The concept of dialectics was given new life by Hegel (following Fichte), whose dialectically dynamic model of nature and of history made it, as it were, a fundamental aspect of the nature of reality (instead of regarding the contradictions into which dialectics leads as a sign of the sterility of the dialectical method, as Kant tended to do in his Critique of Pure Reason).[16][17] In the mid-19th century, the concept of "dialectic" was appropriated by Marx (see, for example, Das Kapital, published in 1867) and Engels and retooled in a non-idealist manner, becoming a crucial notion in their philosophy of dialectical materialism. Thus this concept has played a prominent role on the world stage and in world history. In contemporary polemics, "dialectics" may also refer to an understanding of how we can or should perceive the world (epistemology); an assertion that the nature of the world outside one's perception is interconnected, contradictory, and dynamic (ontology); or it can refer to a method of presentation of ideas and conclusions (discourse). According to Hegel, "dialectic" is the method by which human history unfolds; that is to say, history progresses as a dialectical process.

The Secret of Hegel

Hegelian dialectic, usually presented in a three-fold 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 himself never used that specific formulation. Hegel ascribed that terminology to Kant.[18] Carrying on Kant's work, Fichte 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. Sometimes Hegel would use the terms, Immediate-Mediated-Concrete. Hegel used these terms hundreds of times throughout his works.[19]

The formula, Thesis-Antithesis-Synthesis, does not explain why the Thesis requires an Antithesis. However, the formula, Abstract-Negative-Concrete, suggests a flaw in any initial thesis—it is too abstract and lacks the negative of trial, error and experience. The same applies to the formula, Immediate-Mediated-Concrete. For Hegel, the Concrete, the Synthesis, the Absolute, must always pass through the phase of the Negative, that is, Mediation. This is the actual essence of what is popularly called Hegelian Dialectics.

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).[20]

In the Logic, for instance, Hegel describes a dialectic of existence: 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.[21]

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 slavery to self-unification and realization as the rational, constitutional state 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.
