Flawed, misleading, and false arguments are everywhere. From advertisers trying to separate you from your money, to politicians trying to sway your vote, to friends who want you to agree with them, your belief structure is constantly under attack. Logic is intellectual self-defense against such assaults on reason and also a method of quality control for checking the validity of your own views. But beyond these very practical benefits, informal logic-the kind we apply in daily life-is the gateway to an elegant and fascinating branch of philosophy known as formal logic, which is philosophy’s equivalent to calculus. Formal logic is a breathtakingly versatile tool. Much like a Swiss army knife for the incisive mind, it is a powerful mode of inquiry that can lead to surprising and worldview-shifting conclusions. Award-winning Professor Steven Gimbel guides you with wit and charm through the full scope of this immensely rewarding subject in An Introduction to Formal Logic, that teach you logic from the ground up-from the fallacies of everyday thinking to cutting edge ideas on the frontiers of the discipline.
