Lovely and Suspect Qualities

Abstract

A family of compelling intuitions work to keep "the problem of consciousness" systematically insoluble, and David Rosenthal, in a series of papers including the one under discussion, has been resolutely driving these intuitions apart, exposing them individually to the light, and proposing alternatives. In this instance the intuition that has seemed sacrosanct, but falls to his analysis, is the intuition that "sensory quality" and consciousness are necessarily united: that, for instance, there could not be unconscious pains, or unconscious subjective shades of blue, or unconscious aromas of freshly roasted coffee beans. The particular airborne polymers that are the vehicles of freshly roasted coffee beans could exist, of course, in the absence of any observer, and hence of any consciousness, but the sensory quality of that aroma requires--according to well-entrenched intuition--not only an observer but a conscious observer. Such properties have no esse except as percipi.
