 Another example that motivates the view that experiences have Fregean contents involves perceptual constancies. In the case of color constancy, a table can look such a way that one would readily judge that it is uniformly brown, even though one can discern variations in lightness and darkness. Sometimes the variations are brought into focus by considering how many different shades of paint one would have to use to paint a realistic picture of the table. The central problem these cases pose for the theory of experiential content is to say exactly what ‘lightness and darkness’ are lightness and darkness of: since there is a good sense in which the table looks brown, it is not variation in the table’s color; but the variations seems nonetheless to be closely related to color. Size constancy illustrates the same problem: a departing train does not appear to shrink as it moves away from you; but there is something like size (even if it is not the size of the train) that does appear to lessen, and the problem for the theory of content is say what this is. Accounting for the constancies is a problem for the theory of experience content, because both the constant features and the varying ones are reflected in phenomenology, so by the phenomenal adequacy constraint, the contents should reflect them. The problem presented by the constancies is to show how it is that the constant and varying features don’t conflict in such a way as to make the experience falsidical (for having contradictory contents).
