Doubt Your Doubts with Equal Rigor

Keller revolutionizes how we think about skepticism by revealing that 'All doubts... are really a set of alternate beliefs.' When someone doubts Christianity because 'there can't be just one true religion,' they're expressing an unprovable faith commitment to religious pluralism. This insight dismantles the myth of neutral skepticism. Keller challenges skeptics to examine their doubts with the same intellectual rigor they demand from believers: 'A faith without some doubts is like a human body without any antibodies in it.' The example of a skeptic who realizes their disbelief in miracles stems from an unprovable commitment to philosophical naturalism illustrates how doubt itself requires faith. This reframes the conversation between believers and skeptics as a dialogue between different faith positions rather than faith versus reason.
