Abstract
G. E. Moore famously argued against skepticism and idealism
by appealing to their inconsistency with alleged certainties, like
the existence of his own hands. Recently, some philosophers
have offered analogous arguments against revisionary views
about ethics such as metaethical error theory. These arguments
appeal to the inconsistency of error theory with seemingly
obvious moral claims like “it is wrong to torture an innocent
child just for fun.” It might seem that such ‘Moorean’
arguments in ethics will stand or fall with Moore’s own
arguments in metaphysics and epistemology, in virtue of their
shared structure. I argue that this is not so. I suggest that the
epistemic force of the canonical Moorean arguments can best be
understood to rest on asymmetries in indirect evidence. I then
argue that this explanation suggests that Moorean arguments
are less promising in ethics than they are against Moore’s own
targets. I conclude by examining the competing attempt to
vindicate Moorean arguments by appealing to Rawls’s method
of reflective equilibrium
