 Both Toon (2012) and Levy (2015) articulate the direct view by drawing on Walton’s (1990) theory of make-believe. At the heart of this theory is the notion of a game of make-believe (see the SEP entry on  imagination  for further discussion). We play such a game if, for instance, when walking through a forest we imagine that stumps are bears and if we spot a stump we imagine that we spot a bear. In Walton’s terminology the stumps are props, and the rule that we imagine a bear when we see a stump is a principle of generation. Together a prop and principle of generation prescribe what is to be imagined. Walton considers a vast variety of different props, including statues and works of literary fiction. Toon focuses on the particular kind of game in which we are prescribed to imagine something of a real world object. A statue showing Napoleon on horseback (Toon 2012: 37) is a prop mandating us to imagine, for instance, that Napoleon has a certain physiognomy and certain facial expressions. When reading The War of the Worlds (2012: 39) we are prescribed to imagine that the dome of St Paul’s Cathedral has been attacked by aliens and now has a gaping hole on its western side.
