 Against the historical orthodoxy, the contemporary tendency is to recognize that there is at least one species of imagination—propositional imagination—that does not require mental imagery. For example, Kendall Walton simply states, “imagining can occur without imagery” (1990: 13). In turn, against this contemporary tendency, Amy Kind (2001) argues that an image-based account can explain three crucial features of imagination—directedness, active nature, and phenomenological character—better than its imageless counterpart. As a partial reconciliation of the two, Peter Langland-Hassan (2015) develops a pluralist position on which there exists a variety of imaginative attitudes, including ones that can take on hybrid contents that are partly propositional and partly sensorily imagistic. (For a nuanced overview of this debate, see Gregory 2016: 103–106.)
