Jonah Wilberg: Dennett, Orwell and Stalin Abstract: In this paper I review some recent work in cognitive psychology and assess its significance for Daniel Dennett’s well- known argument against the ‘Cartesian Theatre’ model of consciousness. In a crucial step of his argument, Dennett distinguishes between ‘Orwellian’ and ‘Stalinesque’ explanations of certain perceptual illusions and holds that there is no evidence to support one over the other. But recent empirical work appears to challenge this claim. The ‘Optimal Smoothing’ model of Rajesh Rao, David Eagleman and Terrence Sejnowski implies a Stalinesque explanation of the relevant illusions, and Michael Tye has used their work in support of his own Stalinesque account. On the other hand, Rick Grush has developed a model of perception at small time-scales that implies an Orwellian account. However, I argue that the evidence adduced in support of these empirical models is in fact neutral between Orwellian and Stalinesque explanations, leaving Dennett’s argument unscathed.
