 Thomas Reid’s (1710–1796) moral philosophy does not neatly fit into this scheme of classification. To be sure, some characterize Reid as a rationalist working within the tradition of Clarke and Price (see MacIntyre 1966 and Rawls 2000, Introduction). One can see why. Reid, after all, affirms core rationalist claims, such as that there is a body of necessary moral principles that are self-evident to the ordinary person. But there are important elements of Reid’s thought that do not fit the rationalist paradigm. For example, Reid defends the view that all normal, mature human beings are endowed with a moral sense. Like philosophers such as Hutcheson and Hume, Reid claims that the moral sense yields sentiments of various sorts that themselves occasion “our first moral conceptions,” such as the apprehension that an act is approbation-worthy (EAP V.ii: 279). This account of concept formation, according to some philosophers, would make Reid’s position a version of sentimentalism (see D’Arms 2005). In this respect, Reid’s position resembles not Clarke’s and Price’s but Hutcheson’s and Hume’s.
