UMass Philosophy 105: Practical Reasoning

Fall 2017 – Prof. Kevin C. Klement and TA Daniel Hadad

Tuesdays and Thursdays 11:30am–12:20pm in 123 LGRT with Friday discussions

Course description

This course covers methods for understanding and evaluating reasoning, arguments and inferences, of the sort found in daily life, political speeches, academic writing and beyond. We address such questions as: What is the structure of an argument? What considerations are relevant for determining its strength and cogency? What sorts of appeals to quantitative and scientific data are appropriate, and what sorts aren’t? What, if any, kinds of reasoning patterns can be identified as fallacious or abusive? How can we understand and overcome cognitive biases? This is an analytic reasoning (R2) course, and 4 credits.
