Attempts to illuminate the question of what is involved in our being able to say that things have colours. Sibley argues that imaginable contingent changes could give rise to extensive disagreements, difficulties, and complexities in stating and applying decision procedures, and, consequently, apparent grounds for scepticism, even with matters as objective as colours or tastes. In non-aesthetic realms, however, this possibility does not rule out truth and falsity of attribution, and thereby does not exclude objectivity. This may give some weight to the belief that aesthetic objectivity can be defended along parallel lines.
