 Pessimists, notably Peter Van Inwagen (1998: 70), doubt that imagination can give us an accurate understanding of scenarios that are “remote from the practical business of everyday life”, such as those called upon in philosophical modal arguments. Optimists typically take it as a given that there is some connection between imagination and metaphysical modal knowledge, but focus on understanding where the connection is imperfect, such as when one (apparently) imagines the impossible. To just give a few examples, Saul Kripke (1972 [1980]), Stephen Yablo (1993), David Chalmers (2002), Dominic Gregory (2004), Timothy Williamson (2007, 2016), Peter Kung (2010), and Magdalena Balcerak Jackson (2018) have each developed a distinctive approach to this task. For example, Kripke adopts a redescription approach to modeling (some) modal errors: in some cases where one is apparently imagining the impossible, one is in fact imagining a possible scenario but misconstruing it as an impossible one. On this diagnosis, in such cases, the error resides not with imaginative capacities, but with the capacity to describe one’s own imaginings.
