When an object is seen, some of its particular shape, colour or kind may also be apprehended. Yet being a body or an accident cannot simply be declared the single common essence of every possible object of sight: their different natures make that claim problematic.
The reply distinguishes apprehension of a thing’s identity or actuality from apprehension of its detailed sensible properties. The argument for divine vision concerns the former possibility, not the perception of bodily shape, colour or magnitude in God.
