 As shown in sections 5 and 6, Cook Wilson’s views on knowledge and perception are now once more involved in contemporary debates. They had remained influential all along, although his name was often not mentioned. His peculiar combination of the claims that knowledge is a factive state of mind and that it is undefinable, argued for anew by J. L. Austin, has been taken up and further developed by John McDowell (McDowell 1994, 1998), Charles Travis (Travis 1989, 2008), and Timothy Williamson (Williamson 2000, 2007), who is currently Wykeham Professor of Logic, New College. One has, therefore, what Charles Travis once described as “an Oxford tradition despite itself” (Travis (1989, xii), on this last point, see also Williamson (2007, 269–270n)).
