 Lackey also asks us to consider “the possibility of natural innate knowledge” (Lackey 2007: 358). Surely such knowledge is possible, so an adequate theory of knowledge must accommodate the possibility. But “it seems highly unlikely that a subject would deserve credit for such knowledge”. For the belief’s origin, “such as natural selection or some other evolutionary mechanism”, would be the most salient part of the explanation for why you had the true belief. So the credit thesis is false.
