Thinking Critically vs Skeptically
There shouldn't be a difference between thinking critically vs skeptically, for to think critically is to think skeptically, and vice versa. So why do I write about this? The answer in a word: Faith. Believers can and do think critically, especially the best of the best, like Alvin Plantinga, Richard Swinburne and William Lane Craig. Other notable Christian scholars are Paul Copan, Randal Rauser, Victor Reppert, David Marshall, and Matt Flannagan who regularly engage in apologetics against atheists like me. But they are not truly critical thinkers since they do not think skeptically.
Teaching students to be critical thinkers is very important but teaching them to have a skeptical disposition is more important. Critical thinking should lead to this disposition. The problem is that faith is a critical thinking stopper. It builds up a wall that stops believers dead in their tracks. They dare not go beyond it to the proper conclusion when applying the standards of critical thinking. Now I taught critical thinking classes as a Christian believer. So I know exactly what they are doing. Norman Geisler, one of the leading Christian apologists who defends the indefensible, even co-wrote a book with Ronald M. Brooks titled, Come, Let Us Reason: An Introduction to Logical Thinking.
So what's the problem? Faith. Faith stunts one's critical thinking skills. It prohibits a person of faith from applying the set of critical thinking skills we all agree about. You can see this by how they argue, which I am documenting here. What believers do is to defend their faith rather than look critically at it, no matter what the intellectual cost. Stephen Law is right: “Anything based on faith, no matter how ludicrous, can be made to be consistent with the available evidence, given a little patience and ingenuity.” (Believing Bullshit, p. 75). If Christian apologists could think logically, without the perceived need to defend their religious sect's faith, they would see they are not thinking consistently critically.
In the hopes I can help nudge them along this road I recommend reading Theodore Schick and Lewis Vaughn's college textbook, How to Think About Weird Things: Critical Thinking for a New Age.
