I worry I'm being terribly obtuse here, but one of Brandom's central arguments totally loses me. Over and over again he contrasts mere classification with inference, claiming the former is not indicative of conceptual mastery while the latter is. This underwrites his dismissal of animals as "merely sentient," as he baldly groups (it should be noted with no citation of any relevant empirical research; see great Wolfendale/Silcox discussion HERE on this issue) parrot and pigeon behavior with that of thermometers and rusting iron, contrasting this with humans who are doing something more.
But when he says what we do that is more it is incredibly paltry, in fact the kind of thing that computer programs also do well. Here's a representative passage from Reason in Philosophy.
One could at this piont throw up one's hands, jettison the functionalist project, and concede that what is missing can only be supplied by invoking intrinsically conceptually contentful states of understanding-something that we concept-mongering sapients have, but that mere sentients such as pigeons do not. But there is an alternative. The rationalist's idea is that what is distinctive of the conceptual is its specifically inferential articulation. For a response reliably differentially elicited by red things to qualify as the application of a concept, it must have the significance of a move in the game of giving and asking for reasons. It must be available as a premise for drawing further conclusions, and be liable to challenge by inferences from premises with incompatible consequences. Grasping the concept red requires practical mastery of its inferential role, as well as its non-inferential role as an appropriate response to certain sorts of stimuli. This means being able to discriminate what follows from it, what it follows from, and what is incompatible with it-endorsing in practice the move from red to colored and from scarlet to red, and treating red as ruling out green. (Brandom 2009, 184)
Chinese room anyone? What am I missing?
Of course, the very highest conceptual ability Brandom writes about in the fantastic Chapter 3 of Reason
in Philosophy, the Hegelian/existentialist ability to change concepts and reinvent a history that shows this change to be rational, is something that computers can't do. In fact, the old school of theory revision (where you just have to derive a good consistent subset of an inconsistent theory) is computationally intractable in all sorts of ways. However, these abilities are also the ones that are very, very hard for humans too!
So Brandom seems to either have to say that a simple expert system programmed in LISP or PROLOG is sapient, or to hold that only philosophers are sapient. Something's gone wrong.
Right after the above quote Brandom writes,
(Indeed, the considerations advanced by the pragmatist can be seen to be subsumed by those advanced by the rationalist, for the inferential role of a claim or concept includes its service as a premise in practical inferences: those whose conclusions are intentional actions.) (ibid)
Richard Dreyfus would strongly beg to differ here (and What Computers Still Can't Do should still be required reading). His Heideggerian critique of linguaform explanations just is a critique of this kind of assurance. I think it is here that Brandom goes wrong, and this Summer hope to show so with a paper on Heideggerian world-richness how this works (see my earlier post HERE on how this will go; I've also got to read Okrent's fascinating new book while doing this).
[Addendum: the same article has a very nice discussion of how "the generality problem" for epistemic reliabilism and "the disjunction problem"/gavagai issue play out, but again Brandom almost constitutively deals in false dichotomies whenever animals come up. He acts as if the disjunction problem (i.e. "is the frog responding to flies or moving dots") occurs only when we try to attribute conceptual mastery to animals, but that inference solves the problem for us, e.g.
What picks out one kind of thing as what is being reported to is a matter of the inferential commitments that response is involved in. These inferential consequences of going into a state make it clear that what is being classified is something outside the system. They are what determine that a physicist is reporting the presence of a mu meson in a bubble chamber, and not simply a large hook-shaped pattern. For the consequences of classifying something as a microscopic mu meson are quite different from those of classifying something as a macroscopic hook-shaped trace. It is the lack of such consequences that makes Dretske's dual thermometer liable to a disjunctive proximal interpretation (ibid, 195)
But surely it is not too science fictiony to imagine an alien race with a more intensionally rich idiom for whom our physicist's mu meson is just as crude as the frog's fly or moving spot, that is where the reactions to the mu meson are reactions to two different things that co-occur enough for it to work for human physicists.
And we don't have to go to aliens, normal human expertise do this, think if the experts' jadeite and nephrite to the non-experts jade (which is correctly applied either to jadeite or nephrite). And I'm sure we seem incredibly naive to our dogs in terms of how we differentially respond to smells.
Again, Brandom treats something that admits all sorts of degrees as if it were an on-off switch. I'll just reiterate that I think that this is a function of the way he is slighting "pragmatist" explanations, and that one can make sense of intensional richness entirely in terms of practical means-ends behavior.
Again, there are adult humans who are entirely non-linguistic (being born deaf and never having learned a language) who are migrant farmers. These people have been studied. They certainly can differentiate barn facades from real barns, and the abilities that make that possible for them interact with possible courses of action in all sorts or ways relevant to attributing to them conceptual mastery. Or consider a severe aphasic who only retains the word "red" but whose behavior makes it clear she grasps the relevant concept. As far as I understand him, Brandom is stuck a priori saying these things aren't possible. But they are actual, so of course they are possible. Again, I think the solution is to work out Heidegger's notion of world richness along early Heideggerian lines.]
[ADDENDUM TO THE ADDENDUM:
Here's another one from the next essay, which presents itself as advice to cognitive scientists, (without citing any actual cognitive science).
We might train a parrot reliably to respond differentially to the visible presence of red things by squawking "That's red." It would not yet be describing things as red, would not be applying the concept of red to them, because the noise it makes has no significance for it. It does not know that it follows from something's being red that it is colored, that it cannot be wholly green, and so on. Ignorant as it is of those inferential consequences, the parrot does not grasp the concept (ibid. 204).
Does Brandom mean to say that speakers of language with impoverished color words relative to ours (there are plenty of languages with only two, three, or four color words), do not grasp the concept of Red because they don't conclude that red things aren't green? This would be puerile, and really just be the result of individuating content too finely, with the result being that people with different beliefs end up having different concepts automatically.
So I guess it's that the parrot makes no conclusions from her labeling something red. But Brandom and Sellars include "practical inferences" and clearly the Parrot will manifest all sorts of these. So does he just have a catastrophically empirically ill informed picture of bird cognition?
Weirdly, on the next page he says that one can stretch the word "conceptual" to include animals and computers, but that such things still don't have "genuinely descriptive-concepts" as if the distinction between being descriptive and not descriptive was clear. But then he makes the distinction in terms of drawing inferences in the first case and not the second. Does he mean inferences in natural language? Then aphasics and adult deaf non-language users have no concepts! So does he allow that practical inferences could be sufficient? Then he has to admit that there is continuum with higher animals such as parrots, dolphins, chimps, etc. closer to the average human. But he refuses to do this. Again, I'm not sure if this is just because he hasn't studied any of the empirical research about animal cognition, or what.]
