 Can we really imagine zombies? Daniel Dennett thinks those who accept the conceivability of zombies have failed to imagine them thoroughly enough: ‘they invariably underestimate the task of conception (or imagination), and end up imagining something that violates their own definition’ (1995, p. 322. Marcus 2004 makes a related point; see also Woodling 2014). Given his broadly functionalist model of consciousness, he argues, we can see why the ‘putative contrast between zombies and conscious beings is illusory’ (325. See also his 1991; 1999). Consciousness is ‘not a single wonderful separable thing … but a huge complex of many different informational capacities’ (1995, 324. Cottrell 1999 supports this approach).
