2.182 Every picture is also a logical picture. (On the other hand, for instance, not every picture is a spatial one.)

Well, why would this be? What determines a picture's form of representation? I would have expected "Every picture can be a logical picture," but that isn't what we get. That aside, we are back to the idea of logic (or the logical) as something like a realm beyond, including, the realms of space, color, etc. But this spatial metaphor is obviously dangerous, since it is only a metaphor. For what?
