|Twin Earth||I 572
Twin Earth/Putnam/DennettVsPutnam: he calls for a leap in reference, a leap in intentionality.
Dennett: one could now tend to think that the inner intentionality had a certain "inertia". The brain cannot focus on one thing and mean another. (Wittgenstein).
Twin Earth/Dennett/VsPutnam: you cannot tell a story under the assumption that tables are no tables, even though they look like tables and are used like tables.
Anything else would be a "living creature that looks like Fury" (but is not Fury).
But if there are "Butterhorses" on the twin earth which are in all aspects like our horses, then Butterhorses are horses - not an earthly sort of horses, but horses after all.
((s) that is why the twin earth water does have a different chemical formula in Putnam: YXZ.
Dennett: of course you can also represented a stricter opinion, according to which the non-earthly horses are a separate species. Both is possible. ((s) VsDennett: it depends on how you define determination). ((s) that only works with "hidden" properties)
Twin Earth/DennettVsPutnam: he tries to close the gap by saying that we are referring to natural types, whether we know it or not.
Dennett: But what types are natural? A breed is as natural as a species or a genus.
