Moral epistemology concerns moral knowledge and things related to moral knowledge. Is it possible for one to know that torturing babies for fun is wrong? Can one know that slavery is unjust? Moral skeptics doubt the possibility of moral knowledge and doubt its veracity. Some argue that the persistence of wide-spread moral disagreement among peoples, such as differing views on the morality of infanticide, abortion, and capital punishment, suggests there is no fact of the matter regarding moral claims. Some moral theorists argue for the possibility of justified moral beliefs sufficient to yield moral knowledge. Moral coherentists claims that moral beliefs are justified in virtue of being part of a coherent body of beliefs. Reflective equilibrium is a method of moral justification that is often regarded as a form of moral coherentism. It is a way of resolving conflicts between intuitive moral judgments and moral principles that seek to capture those judgments. Intuitionism is an alternative approach to the justification of moral beliefs. On this theory, moral beliefs are non-inferentially justified. Additionally, some theorists endorse moral rationalism. On this view, it is possible to have moral knowledge even when that knowledge is not based on sense experience. Moral knowledge is often compared to mathematical knowledge. Lastly, moral agents always operate under moral uncertainty. It is impossible to perfectly predict the moral goodness or value that will result from a given course of action. Various approaches try to deal with moral uncertainty, often by incorporating the calculation of expected utility into moral choice situations.
Brink 1989 argues that coherence between a moral belief and one’s other beliefs can justify that moral belief. Sayre-McCord 1996 also endorses this view but argues that things other than one’s beliefs can factor into coherence and justification. Audi 2005 and Huemer 2005 defend comprehensive accounts of moral intuitionism, but Sinnott-Armstrong 2006 argues that moral beliefs are not justified non-inferentially. McGrath 2008 argues that moral disagreement can prevent one from obtaining moral knowledge when one’s peer shares one’s basic moral commitments, yet Wedgwood 2007 argues against this position. Peacocke 2003 and Setiya 2012 defend accounts of moral rationalism involving the possession of moral concepts. Rawls 1971 articulates the method of reflective equilibrium in defending how one can arrive at the best conception of justice. Daniels 1996 extends the method of reflective equilibrium to include background theories of human nature and social stability.
