A Crash Course in Critical Thinking
Greg Koukl, in the May/June 2008 issue of Solid Ground offers a crash course in critical thinking:
The primary purpose of reason is to help us discover what is true. The primary tool of reason is argument. An argument is a specific kind of thing. Think of it like a simple house, a roof supported by walls. The roof is the conclusion, and the walls are the supporting ideas. If the walls are solid, the conclusion rests securely on its supporting structure. If the walls collapse, the roof comes down, and the argument is defeated.
Looking at some of the arguments of the New Athiests, he shows how to develop a game plan for evaluating any argument. He does so by suggesting we ask 4 basic questions:
1. What is the claim being made?
2. What are the reasons given to support the claim?
3. Which appeals are irrelevant?
4. Does the conclusion follow from the evidence?
I recommend the entire article if you wish to learn to reason more carefully through any argument.
