 Another topic concerning spatial representation in experience is the relation between representing locations of things, on the one hand, and representing things as mind-independent, on the other. According to some philosophers, for the case of visual experience, representing things as occupying three dimensions of space suffices for representing them as mind-independent (see Strawson 1958, Peacocke 1983, Masrour 2011; for dissent, see Smith ch 5, and 2000). According to others, visual experience represents spatial locations as locations from which one could act (Schellenberg 2007).  [2]
