Etymology: From logike, from logica, from λογική, from properly feminine of λογικός, from λόγος.
Logic is the systematic and coherent study of reasoning, inference, and valid argumentation. It involves the examination of principles and structures of reasoning to determine their soundness and validity. Logic establishes rules and methods for distinguishing between correct and incorrect reasoning and seeks to understand, analyze, and evaluate the relationships between statements and propositions. It enables individuals to make accurate deductions, identify fallacies, and assess the truth or falsehood of a given argument.
the science or art of exact reasoning, or of pure and formal thought, or of the laws according to which the processes of pure thinking should be conducted; the science of the formation and application of general notions; the science of generalization, judgment, classification, reasoning, and systematic arrangement; correct reasoning
a treatise on logic; as, Mill's Logic
Etymology: [OE. logike, F. logique, L. logica, logice, Gr. logikh` (sc. te`chnh), fr. logiko`s belonging to speaking or reason, fr. lo`gos speech, reason, le`gein to say, speak. See Legend.]
Logic has two meanings: first, it describes the use of valid reasoning where it is used in most intellectual activities, including philosophy and science, or, second, it describes the study of modes of reasoning. It is primarily studied in the disciplines of philosophy, mathematics, semantics, and computer science. It examines general forms that arguments may take. In mathematics, it is the study of valid inferences within some formal language. Logic is also studied in argumentation theory. Logic was studied in several ancient civilizations, including India, China, Persia and Greece. In the West, logic was established as a formal discipline by Aristotle, who gave it a fundamental place in philosophy. The study of logic was part of the classical trivium, which also included grammar and rhetoric. In the East, logic was developed by Buddhists and Jainists. Logic is often divided into three parts, inductive reasoning, abductive reasoning, and deductive reasoning.
