 During the twentieth century, secondary literature on Cook Wilson’s philosophy was not considerable, with a few papers of unequal value by Foster (1931), Furlong (1941), Lloyd Beck (1931) and Robinson (1928a, 1928b), along with a few studies on universals in the post-war years (see section 7), and only one valuable commentary, Richard Robinson’s The Province of Logic (Robinson 1931). Interest in the study of his philosophy was only revived at the beginning of this century, with Marion (2000) giving a first overview of Oxford Realism. In a short book, Kohne (2010) charts the views of Cook Wilson, Prichard and Austin on knowledge as a mental state. An important contribution, Kalderon &amp; Travis (2013) secured Oxford Realism’s place in the history of analytic philosophy, comparing it with other forms of realism in Frege, Russell and Moore, while drawing links with later developments in the writings of J. L. Austin, J. M. Hinton and John McDowell. As a result of this revival of interest, the philosophies of J. L. Austin (Longworth 2018a, 2018b &amp; 2019, and the entry to this Encyclopedia) and of Wilfrid Sellars (Brandhoff 2020) are now being re-interpreted in light of Cook Wilson’s legacy.
