Abstract

In “Innocuous Infallibility,” Earl Conee argues that the infallibility to which I argue Internalism is committed, in “An Argument that Internalism Requires Infallibility,” is harmless and trivial. I maintain that this overlooks the fact that Internalism makes use of an intuitive notion of ‘epistemic twinhood’ to drive its position, rather than one antecedently defined with a filled‐out notion of ‘relevant epistemic circumstances’. Conee is correct that any theory requires, and trivially gets, some sort of infallibility‐but it is not trivial that there is a coherent and univocal notion of the sort of relevant circumstances‐and so, twinhood and infallibility‐behind the Internalist strategy and motivation.
