Predicates, Smehdicates Notice that it won't do to just say that there are no types, just inscriptions that we are regularly disposed to react in a certain behavioristically specified way, since there must be a regularity for us to respond to. That is, there must be something that accounts for the similarity of the various X inscriptions, and this can't be just our behavior, as we are dispositionally inclined to regularly react to Xs because they are similar, not the other way around. — Nagase
But language is a much messier affair than this. In a language such as English, there is a considerable range of sounds that
count as a given phoneme. Not just anything, but also not all that sharply circumscribed because we change what will count based on context. There are allophones allowable when singing that would seem strange in everyday conversation. Toddlers utter sentences in which the prosody is right and just a couple of the phonemes are close to standard, and that counts. You use different allophones when whispering or screaming, and so on.
Paul Grice tells a story about an Oxford college that hired a new don they were very excited to get. The only trouble was he had a dog, and dogs were forbidden. So they held a meeting and "deemed" his dog a cat. Grice then wryly comments (this is all apropos his theory of meaning) that he suspects we do a lot more
deeming than we realize.
That's one side: the requirement for regularity is not particularly strict, and is responsive to the project of communal living. On the other side: would natural regularity account for our behavior? Whence our disposition to respond similarly? There is still a logical leap in counting numerically distinct objects howsoever similar as "the same", as members of a class, tokens of a type, or exemplars of a property. We must still deem them the same.
I think it comes down to the nature of abstraction, and to what we ignore. A bee is attracted to a certain sort of flower, not to some one particular flower. Nature operates with types. But what does that mean? The bee must still sup from a particular flower rather than a type of flower. The particular flower has to have certain properties and the rest -- its exact height, position, blah blah blah -- are ignored. The required properties in turn must fall in some range, rather than having one specific value.
Sorry to ramble, but I find types thoroughly confounding.
