In order to clarify the relation between consciousness and vagueness, I offer a distinction between two different ways in which the phenomenal character of an experience can be said to be vague: horizontally and vertically. With this distinction in hand, my aim in this paper is twofold: rst, I try to defend strong representationalism from arguments from vagueness that maintain that phenomenal characters are horizontally vague. In order to do so, I deny that the non-transitivity of perceptual indiscriminability entails that phenomenal characters are vague. Second, I object to those proponents of representationalism that appeal to teleological theories of mental content, that thesetheories would require phenomenal characters to be vague in the vertical sense what
doesn’t seem plausible at all.
