Dialectic
Dialectic (Greek: διαλεκτική, dialektikḗ; German: Dialektik), also known as the dialectical method, refers originally to dialogue between people holding different points of view about a subject but wishing to arrive at the truth through reasoned argumentation. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and rhetoric.[1] It has its origins in ancient philosophy and continued to be developed in the Middle Ages.
Hegelianism refigured "dialectic" to no longer refer to a literal dialogue. Instead, the term takes on the specialized meaning of development by way of overcoming internal contradictions. Dialectical materialism, a theory advanced by Karl Marx and Friedrich Engels, adapted the Hegelian dialectic into a materialist theory of history. The legacy of Hegelian and Marxian dialectics has been criticized by philosophers such as Karl Popper and Mario Bunge, who considered it unscientific.
Dialectic implies a developmental process and so does not naturally fit within classical logic. Nevertheless, some twentieth-century logicians have attempted to formalize it.
History[edit]
There are a variety of meanings of dialectic or dialectics within Western philosophy.
Classical philosophy[edit]
In classical philosophy, dialectic (διαλεκτική) is a form of reasoning based upon dialogue of arguments and counter-arguments, advocating propositions (theses) and counter-propositions (antitheses). The outcome of such a dialectic might be the refutation of a relevant proposition, or a synthesis, a combination of the opposing assertions, or a qualitative improvement of the dialogue.[2][3]
The term "dialectic" owes much of its prestige to its role in the philosophies of Socrates and Plato, in the Greek Classical period (5th to 4th centuries BC). Aristotle said that it was the pre-Socratic philosopher Zeno of Elea who invented dialectic, of which the dialogues of Plato are examples of the Socratic dialectical method.[4]
Socratic method[edit]
The Socratic dialogues are a particular form of dialectic known as the method of elenchus (literally, "refutation, scrutiny"[5]) 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.[6] 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 uses enthymemes as the foundation of his argument.[citation needed]
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 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[edit]
In Platonism and Neoplatonism, dialectic assumed an ontological and metaphysical role in that it became 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".[7] In this sense, dialectic is a process of inquiry that does away with hypotheses up to the first principle.[8] It slowly embraces multiplicity in unity. The philosopher Simon Blackburn wrote that the dialectic in this sense is used to understand "the total process of enlightenment, whereby the philosopher is educated so a…
