 Perhaps no region of Sidgwick’s work has been the subject of greater interpretive controversy than his epistemology. The early work of Schneewind (1963), Rawls (1971, 1975), and Schultz (1992) played up the dialectical side of Sidgwick’s approach and the ways in which he anticipated the Rawlsian account of the method of reflective equilibrium. Reactions to any such interpretation, which supposedly accorded a too generous role to “received opinion” in Sidgwick’s methodology, came from Singer (1974) and many others influenced by Hare’s critique of Rawls (see also Sverdlik 1984, and especially, Skelton 2007, 2008, 2010). Rawls himself shifted his ground somewhat in later work, playing up Sidgwick’s “rational intuitionism” (Rawls 1996, 2007). But other recent accounts, notably Brink (1994) and Shaver (1999, 2011, and 2014), have recognized that Sidgwick’s approach contains both dialectical and more purely intuitionist elements, debating whether these can be combined in a consistent or coherent way. Recent work on Sidgwick has also benefited from the renaissance in and rehabilitation of intuitionism, evident in such works as Audi (1997), Parfit (2011), and Stratton-Lake (2002); the latter contains an important contribution by Crisp that effectively distances Sidgwick’s views from cruder versions of intuitionism, though Deigh (2010) has argued forcefully that Sidgwick was too committed to an axiomatic approach that was undermined by developments in analytical philosophy, a point in some ways reminiscent of Donagan’s (1977) critique of Sidgwick’s intuitionism. Schultz (1992, 2004) surveys the development of some of these debates, but this is a very lively area of research in which the history of English moral philosophy from Whewell to Ross is being actively rewritten in dramatic fashion (Hurka 2011, 2014a). Yet it does appear that in the last decade, the scholarly emphasis has been disproportionately on Sidgwick and his successors, notably Ross, rather than Sidgwick and his predecessors, notably Whewell, who remains a comparatively neglected figure (Snyder 2001 [2019], 2006).
