It’s not an assumption, it’s a definition. The existence of that which is neither tangible nor otherwise perceptible cannot be said to be meaningful when all we have are our perceptions.What is the basis for assuming this, though?
In a world without cats and mats, your proposition is meaningless because nobody knows what a cat or a mat is. That aside, the preposition certainly has meaning and utility, but it does not possess independent existence. Even one-word imperative commands like ‘IN’ depend on assumed subjects and objects: you’re looking at the dog and pointing at the door. The word ‘in’ depends on the assumed delinquent dog and the assumed place the owner wants the dog to be: it’s a shortened, linguistically convenient version of ‘you get in there’.The word “on” is meaningful so long as it is part of a truth-bearing proposition. Even in a world without cats and mats, the proposition, “the cat is on the mat”, is meaningful, since it is either true or false.
But we are not speaking of a case in which outside influences affect various peoples’ perceptions. You’ve added the variable of the light affecting A’s vision but not B’s, while that’s not what we were talking about at all.This brings us back to conceptual relativity. The fact that some ascribe one level of greenness to an object is irrelevent to the object’s corresponding wavelength. Imagine both of us are at opposite ends of a garden and we’re looking at the same flower. I see a purple flower and you see a white one. Our conceptual relativity does not determine what the corresponding wavelength is that the flower is instantiating. There may be a light above the garden that tints some flowers a purple color if you are standing at a certain angle.
