 After decades of neglect, the last third of the 20th century saw a resurgence of interest in unified consciousness among analytic philosophers. It began with influential commentaries on Kant in the 1960s (Strawson 1966; Bennett 1966, see also his 1974), as well as discussions by Nagel (1971) and Parfit (1971, 1984). More recently, quite a number of philosophers and a few psychologists have written on the subject, including Marks (1981), Trevarthen (1984), Lockwood (1989, 1994), Hill (1991), Brook (1994), Marcel (1994), Hurley (1994, 1998), Shoemaker (1996, 2003), O’Brien and Opie (1998). The first decades of the 21st century have seen a lot of important new work on the subject: Dainton (2000), Stevenson (2000), Bayne and Chalmers (2003), Hurley (2003), Kennett and Matthews (2003), Rosenthal (2003), Radden (2003), Tye (2003), Zeki (2003), Nikolinakos (2004), Brook and Raymont (2006), LaRock (2007), and Bayne (2008, 2010, the latter a book-length study). Cleeremans (2003) is an excellent collection containing papers by philosophers such as Bayne, Chalmers, Hurley, Shoemaker, Cotterill, and Thompson and psychologists such as Triesman, Humphreys, Engel, Diennes, Perner, and Varela. Blackmore (2004, especially ch. 17) is a good, scientifically-oriented introduction. The section on the unity of consciousness in PhilPapers has 391 entries (as of April 2017), the vast majority from the last twenty years (see  Other Internet Resources).
