ABSTRACT
This chapter discusses that there are such things as moral beliefs, about which it makes sense to ask whether they are true or false, whether they are justified or unjustified, and whether they constitute or fail to constitute knowledge. It focuses on moral skepticism as a claim about moral knowledge and deals with skepticism about moral knowledge and, in particular, knowledge of right and wrong. To sum up, if the Moral Disagreement Argument is to be successful in supporting a general skeptical conclusion, then moral disagreement must be thought of as providing an undercutting defeater for our moral beliefs and hence as indicating that our moral beliefs are not connected, in the right sort of way, to the moral facts. Hence, to the extent that the Moral Disagreement Argument succeeds, it does so by raising the Connection Concern.
