For communication that can even approach efficacy we require a compromise in our insistence of understanding; a neutral ground of relative perception. I know that when I refer to the firetruck as "red" it is anything but. In actuality, I am perceiving not the firetruck itself but the reflection of the spectrum of light waves it will not absorb-in this case the lowest of the rainbow. For the sake of expediency I acquiesce and call the truck red. "When in Rome..." they say. Rome will have burnt to the ground by the time we're done dancing around semantics.
