Vision scientists standardly assume that the goal of vision is to recover properties of the external world. Lehar's “miniature, virtual-reality replica of the external world inside our head” (target article, sect. 10) is an example of this assumption. I propose instead, on evolutionary grounds, that the goal of vision is simply to provide a useful user interface to the external world.
