In an interview on The Stone, New York Time's philosophy blog, Christian philosopher Alvin Plantinga was asked "Why do you think so many philosophers—presumable rational people—are atheists?"

Plantinga's answer shows profound biblical and psychological insight: I'm not a psychologist, so I don't have any special knowledge here. Still, there are some possible explanations. Thomas Nagel, a terrific philosopher and an unusually perceptive atheist, says he simply doesn't want there to be any such person as God. And it isn't hard to see why. For one thing, there would be what some would think was an intolerable invasion of privacy: God would know my every thought long before I thought it. For another, my actions and even my thoughts would be a constant subject of judgment and evaluation.

Possible Preaching Angle:

Basically, these come down to the serious limitation of human autonomy posed by theism. This desire for autonomy can reach very substantial proportions … " In other words, philosophers have the same problem as everyone else—"For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened" (Romans 1:21).
