Abstract
Can moral ignorance excuse? This chapter argues that philosophical debate of this question has been based on a mistaken assumption: namely that excuses are all-or-nothing affairs; to have an excuse is to be blameless. The chapter argues that we should reject this assumption. Excuses are not binary but gradable: they can be weaker or stronger, mitigating blame to greater or lesser extent. This chapter explores the notions of strength of excuses, blame miti- gation and the relationship between excuses and moral responsibility. These ideas open up some principled middle-ground between the two positions staked out in the literature. Moral ignorance may well excuse but it does not exculpate.
