Abstract

Over _Principles_ 42-43, Berkeley worried that we might "in truth" see things existing at a distance from us, in which case they could not plausibly be supposed to exist independently of being perceived. He went on to say that he had developed his new theory of vision to address this worry. This paper argues that the worry is serious and that Berkeley was right to think that it would take nothing less than a theory of vision to address it. The paper further argues that Berkeley's theory of vision fails to adequately address the worry. The locus of the failure is Berkeley's account of what he called "situation." The term has an ambiguity that Berkeley exploited. It can refer to how coloured points are localized on a two dimensional visual field or it can mean how the visual field is oriented with respect to the direction of gravity. Berkeley focused on the second when he needed to explain how the first is possible without granting that we originally experience objects as disposed over at least two spatial dimensions.
