 By understanding incomparability to entail vagueness, Broome disagrees with Raz (Broome 2000, 30). Raz defines incomparability so that it is compatible with vagueness, but not so that it entails vagueness. Griffin also argues that incomparability entails vagueness (1986, 96). Where Broome disagrees with Griffin is with regard to the width and significance of the zone of soft indeterminacy. Broome takes Griffin to suggest that if there is a zone of soft indeterminacy, it is narrow and unimportant. Broome argues that vagueness need not imply either narrowness or lack of importance (2000, 30–31).
