right now my question is, how do we know that color is absolute? for instance, if i call the sky blue, and you call the same blue, how do we know that we're both seeing the same "picture" of blue? what i call blue, you might see as purple (but you'd still call it blue...do you follow?) or you might even see it as red... color names are just assigned, how do we know any two people see ANYTHING the same, or feel things the same, how do we know we arent just all using the same word for two or two million different things?
and while i'm asking questions, why does my beloved feel it necessary to know the thickness of the walls of whatever room he's in?
