Does the visual perception of objects require visual space perception – the perception of space itself? The idea that object seeing requires the perception of space itself – call this the space perception requirement – is subject to serious empirical challenge. For in Bálint’s syndrome it seems that an individual can see an object without a sense of the space it is in or where it is located. Here I will argue that a form of the space perception requirement is defensible in the light of cases of Bálint’s syndrome. I will argue that the spatial perception deficit involved in Bálint’s syndrome is not one in which space and spatial location goes missing. A better way to understand the deficit, I suggest, is in terms of the lack of a visual field of the sort that is involved in ordinary visual experience.
