Given the range and diversity of the field, there is no single article that can comprehensively survey normative ethics. This suggests two alternative routes into the subject. Because of the role played by history in contemporary normative ethics, one route to an overview of the subject is via a historical study such as MacIntyre 1998. It is a strength, not a weakness, of this recently republished classic that the author has a very engaged point of view on his subject matter. More up to date and more comprehensive is the three-volume study consisting of Irwin 2007, Irwin 2008, and Irwin 2009. Alternatively, the second route into the subject draws on individual entries in the main reference overviews of moral philosophy. Comprehensive and very helpful recent reference overviews are Singer 1991, LaFollette 2001, Copp 2007, and Skorupski 2010. These reference overviews are divided fairly evenly between meta-ethical and normative topics.
