 The second option characterizes their difference in functional terms. One purported functional difference between imagination and belief concerns their characteristic connection to actions. If the liar truly believes that his pants are on fire, he will typically attempt to put out the fire by, say, pouring water on himself. By contrast, if the liar merely imagines that his pants are on fire, he will typically do no such thing. While belief outputs to action-generation system, imagination does not (Nichols &amp; Stich 2000, 2003). David Velleman (2000) and Tyler Doggett and Andy Egan (2007) point to particular pretense behaviors to challenge this way of distinguishing imagining and believing. Velleman argues that a belief-desire explanation of children’s pretense behaviors makes children “depressingly unchildlike”. Doggett and Egan argue that during immersive episodes, pretense behaviors can be directly motivated by imagination. In response to these challenges, philosophers typically accept that imagination can have a guidance or stage-setting role in motivating behaviors, but reject that it directly outputs to action-generation system (Van Leeuwen 2009; O’Brien 2005; Funkhouser &amp; Spaulding 2009; Everson 2007; Kind 2011; Currie &amp; Ravenscroft 2002).
