The over-arching claim that I intend to defend in this paper is that while widespread ‘local’ error is conceivable, we cannot, in the end, make sense of the radical sceptical idea that all our perceptual beliefs might be false – that no one has, as it were, ever been in touch with an ‘external world’ at all. To this end, I will show that an asymmetry exists between ‘local’ and ‘global’ sceptical scenarios, such that the possibility of ‘local’ error does (...) not imply that ‘global’ error must also be possible. Instead, we will see that what gives rise to the radical sceptical problem is an unquestioned acceptance of the ‘New Evil Genius Thesis’ (NET) – the notion that I and my ‘envatted’ counterpart share the same perceptual experiences, even though my benighted twin has never had any contact with an ‘external’ reality. Although most contemporary epistemologists take NET for granted, I will show that it cannot, ultimately, be rendered intelligible, and, consequently, that neither can the ‘global’ sceptical scenario that depends on it.

This paper takes issue with Derek Sankey's: ‘Minds, Brains, and Differences in Personal Understanding’, Educational Philosophy and Theory, 39 (2007), pp. 543–558 on the questions of the post-pedagogical classroom and the forms of knowledge. I then try to show that a theory of meaning framed in terms of normative pragmatics is better able than the brain science Sankey relies on to account for the concept of a person or self; the central educational concept of personal understanding; the relation between being (...) a person and membership of the species Homo sapiens; the role of mental images in meaningfulness; the functioning of figurative language; and the Gadamerian notion of understanding as constitutive of the self. It is necessary on the way to answer Sankey's criticisms of correctness, a concept on which any normative theory must rely. (shrink)

I examine what I take to be an important consideration for the later Wittgenstein: the understanding of a rule does not exceed or transcend an understanding of explanations or instructions in the rule. I contend that this consideration plays a central role in the later Wittgenstein's views on rule-following. I first show that it serves as a key premiss in a sceptical argument concerning our ability to follow rules. I then argue that this consideration is vital to Wittgenstein's case against (...) what I describe as a realist view of rules. This realist view requires that our understanding of a rule extend beyond what can be understood from any set of instructions or explanation. For Wittgenstein, because this is to transcend publicly available means of conveying understanding, this realist's understanding is a private understanding. He calls this private source of understanding an ‘intuition’ and the main line of argument against intuition in our understanding of a rule draws, appropriately, on what is called his ‘private language argument’. In this paper, I defend a non-verificationist reading of this argument and its use against the realist so-construed. CiteULike Connotea Del.icio.us What's this? (shrink)

cannot understand the language.”[1] This is not intended to cover (easily imaginable) cases of recording one's experiences in a personal code, for such a code, however obscure in fact, could in principle be deciphered. What Wittgenstein had in mind is a language conceived as necessarily comprehensible only to its single originator because the things which define its vocabulary are necessarily inaccessible to others.

The idea that thinking is a form of talking to oneself was discussed in classical Greece, analyzed by the Medievals and treated as a central issue by the American pragmatists. But whether inner speech is a language unto itself, distinct from outer language, has not been determined. To this end I ask how Saussure's defining ideas about language apply to inner speech. I show that Saussure's ideas, while partly usable, are mainly a poor fit. Inner speech is a variety of (...) language, or perhaps of dialect, with its own unique structure. Given that it is a unique window into human consciousness, I briefly discuss some of the research areas on which it sheds light. (shrink)

Drawing on writers as diverse as Saul Kripke, Stanley Cavell, G. E. M. Anscombe, Jonathan Lear, and Bernard Williams, I offer an interpretation of Wittgenstein's key notion of a form of life that explains why Wittgenstein was so enigmatic about it. Then, I show how Hilary Putnam's criticism of Wittgenstein's philosophy of mathematics and Richard Rorty's support of (what he takes to be) Wittgenstein's legacy in the philosophy of mind both require mistaken assumptions about Wittgenstein's idea of a form of (...) life. Finally, I consider the extent to which the idea of a form of life is subject to Donald Davidson's critique of the idea of a conceptual scheme. (shrink)

The demand for 'criteria of correctness' to identify recurring particulars in Wittgenstein's private language argument favors an idealist interpretation of quantum phenomena.The indeterminacy principle in quantum physics and the logic of the private language argument share a common concern with the limitations by which microphysical or sensation particulars can be reidentified. Wittgenstein's criteria for reidentifying particular recurrent private sensations are so general as to apply with equal force to quantum particulars, and to support the idealist thesis that quantum phenomena are (...) themselves essentially mental or dependent on mental occurrences.
