How to Argue - Philosophical Reasoning: Crash Course Philosophy #2
By Crash Course
Before we dive into the big questions of philosophy, you need to know how to argue properly. We'll start with an overview of deductive reasoning and rational arguments.
Fundamentals: Deductive arguments
By WiPhi
In this video, Geoff Pynn follows up on his introduction to critical thinking by exploring how deductive arguments give us reason to believe their conclusions. Good deductive arguments guarantee their conclusions, and so must be valid (i.e., it must be impossible for the premises to be true while the conclusion is false) and have true premises. Philosophers call arguments like these "sound". You can see whether an argument is sound by trying to think of a counterexample to it, but to see whether its premises are true, you need to do some research. Speaker: Dr. Geoff Pynn, Assistant Professor, Northern llinois University
