The first and most thoroughly developed audience-oriented argumentation text has been updated to its 8th edition: Argumentation and Critical Decision Making presents argumentation as a cooperative, communicative process. This text examines the general principles of argument in a rigorous yet readable manner and then applies those principles to different spheres of life -- law, science, religion, business, government, and politics -- to explore how conventions of argument change when applied to these real-world arenas. Focusing on the dynamics of decision making and using real-life examples to illustrate principles, Argumentation and Critical Decision Making aims to help readers develop practical argumentation skills within the world of their daily lives.
