" What our instruments and brains tell us consists of relative "realities" or cross-sections of "realities." A thermometer, for instance, does not measure length. A yardstick does not measure temperature. A voltmeter tells us nothing about gas pressure. Etc. A poet does not register the same spectrum as a banker. An Eskimo does not perceive the same world as a New York cab driver. Etc. "
