 One notable descriptive taxonomy concerns imagining from the inside versus from the outside (Williams 1973; Wollheim 1973; see Ninan 2016 for an overview). To imagine from the outside that one is Napoleon involves imagining a scenario in which one is Napoleon. To imagine from the inside that one is Napoleon involves that plus something else: namely, that one is occupying the perspective of Napoleon. Imagining from the inside is essentially first-personal, imagining from the outside is not. This distinction between two modes of imagining is especially notable for its implications for thought experiments about the metaphysics of personal identity (Nichols 2008; Ninan 2009; Williams 1973).
