Abstract

Michael Dummett and Crispin Wright1 consider the following puzzle. Imagine a series of coloured patches, beginning with a red patch. Suppose, moreover, that the colour from patch to patch changes gradually so that the last patch is quite clearly not red. However, the change is so gradual that each patch is — to the eye — quite indistinguishable from the next in colour.
