 Non-Reductionism traces at least as far back as Thomas Reid’s (IE [1983, 94–95])—see Wolterstorff (2001) for more on Reid’s view. More recently, various versions of Non-Reductionism have been defended by Austin (1946 [1979]), Welbourne (1979, 1981, 1986, 1994), Evans (1982), A. Ross (1986), Hardwig (1985, 1991), Coady (1992, 1994), Burge (1993, 1997, 2013), Plantinga (1993), Stevenson (1993), Webb (1993), Dummett (1994), Foley (1994), McDowell (1994), Strawson (1994), Williamson (1996, 2000), Millgram (1997), Alvin Goldman (1999), Schmitt (1999), Insole (2000), Owens (2000), Rysiew (2000), Weiner (2003), Graham (2006a), Sosa (2006), McMyler (2011) and Baker and Clark (2018). See also Audi (1997, 1998, 2004, 2006), who defends Non-Reductionism about testimonial knowledge but not about testimonial justification.
