 Manipulating the same and the different alters the distinctions that ground our use of words and thus our standards of knowledge. (In the most extreme case, uniting everything into a “Great One” would leave us unable to communicate linguistically and eliminate all conceptual or propositional knowledge.) The notion that we can realign the boundaries of the same and different without limit signals a radical skepticism about the existence of natural kinds. Indeed, it threatens to leave us without any knowledge at all, since the standards by which to judge whether one knows something are never fixed. It also provides an approach to winning any disputation: instead of seeking objective criteria that fix the correct distinctions between things, disputers just redraw the distinctions between things or kinds in whatever way needed to establish their claim.
