Russell's Teapot

Russell's teapot is an analogy devised by the philosopher Bertrand Russell to illustrate where the burden of proof lies for claims that cannot be empirically disproven. Russell imagines asserting that a small china teapot orbits the sun somewhere between Earth and Mars, too small to be detected by any telescope, and observes that although no one could disprove this claim, no one would be entitled to believe it merely because it cannot be refuted; the burden of proof rests on the person making the claim, not on skeptics to disprove it. Russell applied the analogy directly to claims about the existence of God, arguing that widespread religious belief, reinforced by sacred texts and childhood teaching, can make an otherwise unsupported claim seem reasonable through sheer cultural familiarity, even though social acceptance does nothing to shift the evidentiary burden away from the person making the original unfalsifiable assertion.
