ΔΙΑΛΕΚΤΙΚΗ

Definition

According to the Liddell-Scott-Jones Lexicon, διαλεκτική (dialektikē) is primarily defined as "the art of discussion or debate," derived from the verb διαλέγομαι (dialegomai), "to converse, discuss." It signifies a method of inquiry involving question and answer, aiming to clarify concepts and establish truth through logical argumentation.

In Socratic philosophy, dialectic is famously employed as the elenchus, a method of cross-examination designed to expose contradictions in an interlocutor's beliefs, thereby leading to a recognition of ignorance and a purification of thought. This process, often described as a "midwifery" (μαιευτική), was not about imparting knowledge but about helping others discover it for themselves.

Plato elevated dialectic to the highest science, the ultimate path to apprehending the Forms (Ideas). For Plato, dialectic involves both "collection" (συναγωγή) and "division" (διαίρεσις) – gathering particulars under a common Form and then dividing Forms into their constituent species. This rigorous intellectual ascent enables the philosopher to grasp the true nature of reality.

Aristotle, while acknowledging its importance, distinguished dialectic from demonstrative science (ἀπόδειξις). In his view, dialectic reasons from probable premises (ἔνδοξα) rather than necessary ones, making it suitable for persuasion, debate, and the examination of common opinions, as explored in his work Topics. Its scope thus extended to rhetoric and the practical application of logic.

Word Family

leg-/log- (root of the verb legō, meaning 'to gather, to speak, to reckon')

The Ancient Greek root leg-/log- is fundamental to the Greek language and thought, forming the core of an extensive family of words related to gathering, selecting, speaking, reasoning, and arranging. Initially, the root signified 'to gather, to pick' (cf. Latin legere), but it quickly acquired the meaning 'to speak, to converse,' as speech itself is a form of gathering and arranging words. From this root developed concepts spanning from the simple word to complex logical thought and philosophical methodology.
