Aristotle's ethics: knowledge and morality

There is much controversy over the interpretation of Aristotle's Nicomachean Ethics. One of the debates is over Aristotle's view concerning the source of ethical knowledge. For a long time, it was the general consensus that he was an ethical intellectualist. Richard Sorabji is an exemplary case of a scholar who ascribes to this view and firmly defends the intellectualist understanding. However, in recent years, scholars like Jessica Moss, have argued that he has a non-rational cognitive view, according to which, ethical knowledge is grounded on empirical investigation. Roger Crisp points out numerous tensions in Aristotle's text, which may be a result of a discrepancy that arises when implementing two conflicting ideas, virtue as intellectual and virtue as purely a practice. McDowell offers a view that resolves the dispute between the intellectualists and the empiricists.
