Validity and Fallacies I

Lecture no. 19 from the course: Argumentation: The Study of Effective Reasoning

 Validity and Fallacies I

Taught by Professor David Zarefsky | 30 min | Categories: The Great Courses Plus Online Philosophy & Religion Courses

The central question of this and the next lecture is: What makes a good argument? The answer is validity. In formal reasoning, validity is a matter of structure unrelated to content. In informal reasoning, it means following patterns that have led to good results and avoided fallacies. This lecture examines errors specific to each pattern of inference, and then considers errors of vacuity ("empty" arguments).
