CRITICAL THINKING - Fundamentals: Validity [HD]


In this Wireless Philosophy video, Paul Henne (Duke University) discusses the philosophical concept of validity. After reviewing the structure of an argument, he defines validity: an argument is valid if and only if its premises guarantee the conclusion. He reviews a few examples of validity and invalidity, and he leaves you with one example to figure out on your own. Help us caption & translate this video! http://amara.org/v/GcHM/
