I have to apologise that its taken so long to get this third part up. I had section 7 written when I posted the last part, but a number of things came up at the beginning of this week which have made it difficult for me to finish section 8. Anyway, it’s done, and this caps off my response to Levi’s posts. I had originally wanted to say more about Levi’s claims about Kant, specifically regarding the bits of Kant that he claims to take up, but I need to get on with other things.
Also, Levi has since posted a response to part 2 (here). I don’t want to tackle the points he makes in the detail I’ve gone into below, again, because I need to get on with other things, but I think there are perhaps four quick points that can be made:-
1) Levi now claims that my criticisms of his account of withdrawal can be circumvented by means of his distinction between first order and second order observation. In essence, this is a perspectivalist solution to the problem of how to understand direct and indirect access. The claim is effectively that because we can observe that other systems lack our own particular sensitivities to the environment, we can see that there is some loose sense in which they are not accessing aspects of the environment that we are. We can then by analogy hold that there must be bits of the environment that we are not accessing. I think this will prove very problematic, but I won’t elaborate here.
2) At several points in his response Levi makes the claim that he can address problems I’ve raised for him in regional ontology. For instance, he claims that any problems I’ve raised for him regarding the differences between intentional and non-intentional systems can be handled at the level of the regional ontology of intentional systems. The important thing to point out here is that if Levi introduces new metaphysical resources to account for the intentional relations that we enter into, then he abandons what was supposed to be the real thrust of OOO, because this is tantamount to reintroducing special metaphysical relations that only humans (or intentional systems more broadly defined) can enter into in order to secure the possibility of knowledge. However, if what Levi means here by regional ontology doesn’t involve introducing such specialised metaphysical resources, precisely what does it involve, and how can it help?
3) Levi seems to think that my discussions of a ‘shared apparatus of meaning’ imply something like a static background of meaning available in advance as a condition of the possibility of communication. This couldn’t be further from the truth, indeed, the Brandomian position I adopt more often gets accused of being too dynamic, insofar as it denies that there are anything like analytic truths that fix the meaning of our claims (i.e., it is a form of semantic holism). There are two important upshots of this. On the interpersonal level, communication is less like the exchange of fully formed meanings than it is a co-operative activity in which we negotiate one another’s commitments, the meanings of which are determined by their relations to others. On the broader social level, the inferential norms (or concepts) which determine the relations between sentences (and thus their meanings) are subject to continuous revision, insofar as the process of revising our commitments just is the process of revising our concepts. The only thing which is fixed here is the fundamental norms governing these dynamic activities. Incidentally, Levi also at one point says that Brandom is insufficiently concerned with non-discursive practices. This misses the point that such practices are in fact Brandom’s answer to the objections that his approach is too dynamic. For Brandom, it is shared practices of talking about and engaging with things (what he calls ‘thick’ or ‘object-involving’ practices) that allow for the possibility of interpersonal communication and conceptual revision. To explain this in detail would require too much space (I also don’t think Brandom’s account of this is quite adequate even if it’s on the right track), but it’s important to see that Levi is well off the mark here.
4) Finally, Levi responds to my concerns about representation by invoking what he takes to be adverse connotations of the word. He thinks that focusing upon representation tends to produce epistemologies in which there is too much focus placed upon mental contents, and this tends to obscure the importance of concrete practices, along with the social and historical dimensions of knowledge development and retention. All I can really say to Levi here is that although there are a number of good historical examples in which these coincide (e.g., Descartes), that the connotations he finds say more about his own prejudices than anything else. Brandom’s approach to representation takes account of everything he thinks it would exclude: semantic holism (against self-subsistent mental contents), thick practices, and an account of how both social and historical dimensions of linguistic practice are necessary for representation. Much as was the case with the word ‘normativity’, I think Levi’s reading too much into the notion of ‘representation’, and he needs to get over this if he’s to deal with the variety of issues that it involves (and which I sketched in the last post).
Anyway, onto the main event once more. Here are sections 7 and 8.
