David Sosa (Texas) Phenomenal Failure to Discriminate

If one thing looks the same as a second (in a given respect), and that second thing looks the same as a third, does the first look the same as the third? It is easy to suppose that it need not: but I will defend the position that they do. The crucial distinction is between the relations of indiscriminability (which does not validate transitivity) and of looking the same as (which, I suggest, does).
