 The ten theses revolve around the theme that distinctions are not inherently fixed, but relative to a perspective, and thus can be redrawn or collapsed as we like simply by shifting perspectives. Several of the paradoxes focus on negating commonsense distinctions, in particular spatial and temporal ones, partly by appeal to the relativity of comparisons and partly by appeal to indexicals (Hansen 1992: 262). (A high mountain is not high when seen from space; if I walk southward, a spot that is south of me now will in seconds be north of me.) The fifth thesis, on “the same” and “different,” seems to provide a key to several, perhaps all of the others. It indicates that on some scale or another, anything can be deemed “the same” or “different.”
