 For defenses of theses along the lines of Sufficiency, see Pollock (1974), Pryor (2000) or Huemer (2001, 2007). Their strategies put much weight on what it is like to have an experience (see more in  section 2.4  on this sort of strategy). A different approach tries to exploit the way that experiences come to have their contents, for example by arguing that experiences are likely to have true or accurate contents given the way they come to have their contents. For examples of this strategy, see Burge 2003, Peacocke 2004, Sawyer and Majors 2005, and Setiya 2012: ch. 3.
