The Christian philosopher has a perfect right to the point of view and prephilosophical assumptions he brings to philosophic work; the fact that these are not widely shared outside the Christian or theistic community is interesting but fundamentally irrelevant.
Alvin PlantingaIf you believe in evolution and naturalism then you have a reason not to think your faculties are reliable.
Alvin PlantingaSuppose we concede that if I had been born of Muslim parents in Morocco rather than Christian parents in Michigan, my beliefs would be quite different. [But] the same goes for the pluralist...If the pluralist had been born in [Morocco] he probably wouldn't be a pluralist. Does it follow that...his pluralist beliefs are produced in him by an unreliable belief-producing process?

Alvin PlantingaBut lack of evidence, if indeed evidence is lacking, is no grounds for atheism. No one thinks there is good evidence for the proposition that there are an even number of stars; but also, no one thinks the right conclusion to draw is that there are an uneven number of stars. The right conclusion would instead be agnosticism.
