Moral scepticism

Scepticism in general is the view that we can have little or no knowledge; thus moral scepticism is the view that we can have little or no moral knowledge. Some moral sceptics argue that we cannot have moral knowledge because we cannot get the evidence necessary to justify any moral judgments. More radical moral sceptics argue that we cannot have moral knowledge because in morality there are no truths to be known. These radical sceptics argue either that moral judgments are all false because they erroneously presuppose the real existence of ‘objective values’, or that moral judgments aim to express feelings or influence behaviour instead of stating truths. Critics of moral scepticism, in turn, argue that in at least some cases moral judgments aim to state truths, some of these judgments are in fact true, and we have enough evidence to say that we know these moral truths.
