 A System of Logic is the most extensive work on fallacies since Aristotle’s Sophistical Refutations. Mill’s examples are taken from a wide range of examples in science, politics, economics, religion and philosophy. His classificatory scheme is original and comprehensive. Frederick Rosen (2006) argues that Mill’s pre-occupation with the detection and prevention of fallacies is part of what motivates the celebrated second chapter of On Liberty. Despite these considerations, the Logic is not much referenced by fallacy theorists.
