Read 'The nature of Aristotle's dialectic' here.ĭr Evans explains that while dialectic is concerned with the individual and her perspective, logic is not: “Pure logic is not concerned with the vagaries of the individual's reaction, and indeed in its search for objectivity it is positively prohibited from considering the individual as such.” (75) He adds later: “Aristotle is aware that the conditions of the exercise of dialectical skill are such that, although the dialectician is indeed required to argue his case purely by logical means, he must at the same time not ignore the various ways in which circumstances which are external to his argument can affect its character.” (92) It differs from logic in that it is not concerned with the pursuit of absolute truth, or first principles, but in convincing a person of an argument. It differs from rhetoric in that only logic should be deployed to persuade, and that it is aimed at a particular individual rather than a group, or a crowd. To an extent, this is the same as the familiar “thesis, antithesis, synthesis” to which Aristotle’s dialectic is often reduced, but that formulation actually originated with Johann Fichte (1762 - 1814).ĭialectic is the same as rhetoric in that it is an intellectual activity aimed at changing minds, and is the same as logic in that it relies on reasoning to validate (or invalidate) arguments. AAI3225558.Dialectic is a process of discovery and pedagogy that takes place between two individuals using logical argument, according to Aristotle. Tracy, Kevin, "The development of dialectic from Aristotle to Chrysippus" (2006). Subject AreaĪncient languages|Philosophy Recommended Citation Fifth, the Stoic deduction system is roughly analogous to the first-order fragment of Frege's system, except on two points: it most likely was not designed to accommodate the use of polyadic predicates with multiple quantifiers, although the possibility for doing so inheres in its approach to the analysis of propositions, and it uses the "natural" approach rather than the "axiomatic" approach of Frege. Fourth, the Stoics produced derivations for categorical arguments in their deduction system. Third, the Stoics distinguished "valid" (hugies ) from "true" (alēthes), so that sunartēsis is a standard for the validity rather than the truth of the Stoic conditional (sunhēmmenon). Second, the guiding aim of Chrysippus' logic was to avoid adopting a semantic stance in describing logical forms and explaining logical relationships. First, neither the Peripatetics or the "Megarics" described logical forms of propositional logic Chrysippus was the first to do so. The dissertation yields five principal conclusions. Finally, it uses the resulting narrative to give a detailed account of Stoic formal logic. It then describes how Chrysippus addressed these questions. First it describes the logical doctrines of Aristotle, Theophrastus, and the "Megarics" in such a way as to make clear what questions these predecessors left for Chrysippus. This dissertation approaches the problem through the presentation and interpretation of the ancient source material. Without such a narrative, one cannot explain what, in general, motivated the innovations of Chrysippus, what made Stoic logic coherent as a unified project, or what relationship that project had to earlier work in logic. The scholarship on Stoic logic has not yet presented the history of dialectic from Aristotle to Chrysippus as an intelligible narrative. The evidence for the formal logic of the Stoic philosopher Chrysippus (3rd century BCE) is fragmentary nonetheless it makes clear that not more than a century or so after Prior Analytics, Chrysippus revolutionized formal logic. Aristotle's Prior Analytics (4th century BCE) is the earliest evidence of a formal logic in antiquity. The development of dialectic from Aristotle to Chrysippusįrom Aristotle onward, formal logic was an element of ancient Greek dialectic (dialektikē).
