Logic
Logic is a structure or set of procedures for presenting a rational argument.
Logic, in its broadest sense, refers to the structure and principles of reasoning. It requires the ascription of truth or falsity to premises in an argument and thereby derives the truth or falsity of the conclusion.
There are basic two approaches to logical argument, deductive and inductive. Logic is not about how people actually do argue but about the theoretical structure of argument.
Logical analysis (described further below) is concerned with clarifying language prior to establishing a line of argument.
New World Encyclopedia contributors (2014):
Logic...is most often said to be the study of criteria for the evaluation of arguments, although the exact definition of logic is a matter of controversy among philosophers. However the subject is grounded, the task of the logician is the same: to advance an account of valid and fallacious inference, in order to allow one to distinguish good from bad arguments.
Traditionally, logic is studied as a branch of philosophy. Since the mid-1800s logic has also been commonly studied in mathematics, and, more recently, in set theory and computer science. As a science, logic investigates and classifies the structure of statements and arguments, both through the study of formal systems of inference, often expressed in symbolic or formal language, and through the study of arguments in natural language (a spoken language such as English, Italian, or Japanese). The scope of logic can therefore be very large, ranging from core topics such as the study of fallacies and paradoxes, to specialist analyses of reasoning such as probability, correct reasoning, and arguments involving causality.
