Home›Philosophers›Branch of Philosophy›LogicBranches of PhilosophyLogicLogicReference and ClassificationVerifiedThe branch of philosophy that studies the principles of valid inference: what makes one claim follow from another, and what distinguishes a sound argument from a merely persuasive one. Aristotle's Organon, especially the Prior Analytics, set out the theory of the syllogism and dominated logical study in the West for roughly two thousand years, until the nineteenth and early twentieth century work of Boole, Frege, and Russell reconstructed logic on a formal, symbolic footing and connected it to the foundations of mathematics. Logic underlies every other branch of philosophy in a specific sense: metaphysics, epistemology, and ethics all proceed by argument, and logic is the study of what makes an argument good independently of its subject matter.FactsLogicFAQsConnectionsIn the Other AtlasesSourcesComments (0)Reader Challenges (0)FactsCentral QuestionWell-attestedWhat makes an inference valid: what relation must hold between premises and a conclusion for the conclusion to follow of necessity? 1Key DebateWell-attestedWhether classical logic's own laws, bivalence and the law of excluded middle among them, are fixed and universal or genuinely open to revision: intuitionistic, many-valued, and paraconsistent logics have all been proposed as legitimate rivals to the classical system rather than as mere curiosities, reopening whether logic is discovered whole or built to purpose. 1DisputedKey DebateScholarly debateLogical pluralism versus logical monism: whether classical logic is the single correct account of valid inference, or whether distinct logics, classical, intuitionistic, relevance and paraconsistent among them, can each be correct for different subject matters or purposes. 1JC Beall and Greg Restall's defense of logical pluralism reopened a question earlier logicians treated as closed in favor of classical logic alone.LogicFilter Results81 entriesMovementAllAfrican Epistemology
