Christianity also makes for a better social science than materialism can, precisely because people do act for reasons. People act for reasons, they believe they act for reasons, and they believe their existence is meaningful because their reasoned action leads to meaningful ends. I can’t prove that people are right in these beliefs. But I can prove that most people do have these beliefs (even people who profess materialism). And I assert that the universal fact that people act as if they act for a meaningful reason is evidence that they are right. Not proof, but strong evidence.
I think this is true, but doesn't really get to the core of what undergraduates are likely to be concerned about.
I would welcome suggestions for how to bridge this gap.
