List of basic topics in logic

Logic, a branch of both philosophy and mathematics, is the study of criteria for the evaluation of arguments. The task of the logician is to advance an account of valid and fallacious inference, to allow one to distinguish logical from flawed arguments. Logic investigates and classifies the structure of statements and arguments, both through the study of formal systems of inference and through the study of arguments in natural language. The scope of logic can therefore be very large, ranging from core topics such as the study of fallacies and paradoxes, to specialized analyses of reasoning such as probability, correct reasoning, and arguments involving causality.

The following outline is provided as an overview of and introduction to logic:
