 In defending a view of economics as in this way inexact and employing the method a priori, Mill thought he was able to reconcile his empiricism and his commitment to Ricardo’s economics. Although Mill’s views on economic methodology were challenged later in the nineteenth century by economists who believed that theory was too remote from the contingencies of policy and history (Roscher 1874, Schmoller 1888, 1898), Mill’s methodological views dominated the mainstream of economic theory for a century (for example, Cairnes 1875). Mill’s vision survived the so-called neoclassical revolution in economics beginning in the 1870s and is clearly discernible in the most important methodological treatises concerning neoclassical economics, such as John Neville Keynes’ The Scope and Method of Political Economy (1891) or Lionel Robbins’ An Essay on the Nature and Significance of Economic Science (1932). Hausman (1992) argues that current methodological practice closely resembles Mill’s methodology, despite the fact that few economists explicitly defend it.
