Reasonable standards and exculpating moral ignorance

Abstract

AbstractIt is widely agreed that ignorance of fact exculpates, but does moral ignorance exculpate? If so, does it exculpate in the same way as non-moral ignorance? In this paper I will argue that on one family of views explaining exculpating non-moral ignorance also explains exculpating moral ignorance. The view can be loosely stated in the following way: ignorance counts as an excuse only if it is not the result of a failure to meet some applicable reasonable epistemic standard—call this the Reasonable Epistemic Standards Thesis and call views that accept some version of this principle reasonable standards views. I argue that any plausible reasonable standards view ought to allow that moral ignorance exculpates, at least sometimes, and defend such views against the charge that they are susceptible to clear counterexamples.
