 Many cognitivists, however, think that the knowledge we acquire from literary fiction is not centrally a kind of propositional or even conceptual knowledge, but a kind of practical knowledge. For example, literature can cause us to attend to the world in a more focused way, enriching our perceptual experience and emotional and moral understanding (Diamond 1995; Nussbaum 1985, 1990, 2001; Gibson 2007; Robinson 1995 [1997]). One way it might do this is by being a source of what Davies calls categorial understanding (2007: 146), yielding new categories through which to understand the world, for example quixotic and Kafkaesque (Goodman 1978: ch. 4). It can also provide phenomenal knowledge: knowledge of what it is like to be a certain kind of person or be in a certain kind of situation, and so knowledge that can be put to use in planning or to help us understand other people or the moral complexity of situations (Kieran 1996; Currie 1998; Putnam 1978; Carroll 2002; Swirski 2007).
