Why We Argue (And How We Should): A Guide to Political Disagreement in the Age of Unreason presents an accessible and engaging introduction to the theory of argument, with special emphasis on the way argument works in public political debate. The authors develop a view according to which proper argument is necessary for one's individual cognitive health; this insight is then expanded to the collective health of one's society. Proper argumentation, then, is seen to play a central role in a well-functioning democracy.

Written in a lively style and filled with examples drawn from the real world of contemporary politics, and questions following each chapter to encourage discussion, Why We Argue (And How We Should) reads like a guide for the participation in, and maintenance of, modern democracy. An excellent student resource for courses in critical thinking, political philosophy, and related fields, Why We Argue (And How We Should) is an important contribution to reasoned debate.
