Brian Garrett has criticized my diagnosis of the paradox of self-consciousness. In reply, I focus on the classification of 'I'-thoughts, and show how the notion of immunity to error through misidentification can be used to characterize 'I'-thoughts, even though an important class of 'I'-thoughts (those whose expression involves what Wittgenstein called the use of 'I' as object) are not themselves immune to error through misidentification. 'I'-thoughts which are susceptible to error through misidentification are dependent upon those which are not. The dependence here has to do with how a thinker understands what would defeat such thoughts

Gigerenzer and his co-workers make some bold and striking claims about the relation between the fast and frugal heuristics discussed in their book and the traditional norms of rationality provided by deductive logic and probability theory. We are told, for example, that fast and frugal heuristics such as “Take the Best” replace “the multiple coherence criteria stemming from the laws of logic and probability with multiple correspondence criteria relating to real-world decision performance.” This commentary explores just how we should interpret this proposed replacement of logic and probability theory by fast and frugal heuristics.

The most frequently discussed skeptical arguments in the history of philosophy are to be found in the tightly argued twelve paragraphs of Descartes’ Meditation One. There is considerable controversy about how to interpret the skeptical arguments that Descartes offers; the extent to which those arguments rest upon implicit epistemological and/or metaphysical presuppositions; their originality within the history of skepticism; and the role they play within Cartesian philosophy and natural science. This chapter begins by tracing the complex argumentation of Meditation One. The second section explores the differences between Cartesian skeptical arguments and the skeptical arguments discussed in the ancient world, while the third section considers whether there might be medieval antecedents for the radical doubts that end Meditation One. The final section suggests that the radical nature of the doubts raised in Meditation One has its sources in two fundamental characteristics of Cartesian science: the radical error that Cartesian science posits in our everyday experience of the world, and the hypothetical and (only) morally certain nature of the scientific edifice that is proposed to replace the commonsense view of the world enshrined in Aristotelian science.

Self‐consciousness is a topic located at the intersection of a range of different philosophical concerns. One set of concerns is metaphysical. Another is epistemological. When discussing the phenomenon of consciousness in general, philosophers generally think it possible to give an account of consciousness that is independent of how one understands the objects, properties, and events of which one is conscious. Self‐consciousness is important because of the role it plays in the cognitive economy. Self‐consciousness can be understood either in terms of direct awareness of the self or in terms of propositional awareness. Self‐conscious thoughts can be based on a range of different sources of information. Some of these sources can provide information either about the self or about other people. Some influential accounts of self‐consciousness, such as those of Shoemaker (1963, 1968) and Evans (1982), have attributed a fundamental role to the phenomenon of immunity to error through misidentification.

In Thinking about Consciousness David Papineau develops a position that combines the following four theses: A) Phenomenal properties exist. B) Any phenomenal property is identical to some material property. C) Phenomenal concepts refer to material properties that are identical to phenomenal properties. D) Phenomenal concepts are vague. The overall position is intended to do justice to materialism (in virtue of (B) and (C)), while at the same time accommodating the concerns both of those impressed by the Knowledge Argument and related arguments (in virtue of (A)) and of those skeptical about the prospects for a science of consciousness (in virtue of D)). This paper shows that (A) through (D) cannot be held simultaneously.

This critical notice explores the distinction central to analytic philosophy between the logical study of the normative principles governing rational thought and the psychological study of the processes of thinking. Thomas Nagel maintains (1) that the fundamental principles of reasoning have normative force and make claims to universal validity; (2) that the fundamental principles of reasoning cannot be construed as the expression of contingent forms of life; and (3) that the identification of fundamental principles of reasoning should be completely independent of psychological facts about how people reason. The notice draws upon intuitionist critiques of classical logic and the Allais paradox in expected utility theory to argue that (1) can be consistently combined with the denial of (2) and (3)

This article proposes an object properties approach to object perception. By thinking about objects as clusters of co-instantiated features that possess certain canonical higher-order object properties we can steer a middle way between two extreme views that are dominant in different areas of empirical research into object perception and the development of the object concept. Object perception should be understood in terms of perceptual sensitivity to those object properties, where that perceptual sensitivity can be explained in a manner consistent with the graded representation approach adopted by some connectionist modellers. The object properties approach does justice to the differences between a perceptual system solving the binding problem, on the one hand, and genuinely perceiving objects, on the other, without running into the theoretical problems associated with treating young infants as 'little scientists'.

[1] Recent philosophy of mind and epistemology has seen an important and influential trend towards accounting for at least some features of experiences in content-involving terms. It is a contested point whether ascribing content to experiences can account for all the intrinsic properties of experiences, but on many theories of experiences there are close links between the ascription of content and the ways in which experiences are ascribed and typed. The issues here have both epistemological and psychological dimensions. On the one hand, a theory of experiential content has a fundamental role in explaining how knowledge of the world can be acquired through experience. On the other hand, there are important psychological questions about the phenomenology of experiences and the conditions under which content ascriptions are made

A number of authors have noted that the key steps in Fitch’s argument are not intuitionistically valid, and some have proposed this as a reason for an anti-realist to accept intuitionistic logic (e.g. Williamson 1982, 1988). This line of reasoning rests upon two assumptions. The first is that the premises of Fitch’s argument make sense from an anti-realist point of view – and in particular, that an anti-realist can and should maintain the principle that all truths are knowable. The second is that we have some independent reason for thinking that classical logic is not appropriate in this area. This paper explores these two assumptions in the context of Michael Dummett’s version of anti-realism, with particular reference to the argument from indefinite extensibility developed at various points in Dummett’s writings (e.g. Dummett 1991 Ch. 24). Dummett argues that certain concepts, the indefinitely extensible concepts, are such that we cannot form a clear and determinate conception of all the objects that fall under them. The most familiar examples of indefinitely extensible concepts are mathematical. Dummett discusses the concepts ordinal number, real number, and natural number, which are indefinitely extensible because any conception that one might form of their complete extension can be extended to a more inclusive conception (as, for example, in Cantor’s proof of the non-denumerability of the set of real numbers). This paper argues that the concept of a truth is indefinitely extensible. This gives a Dummettian anti-realist an independent motivation for rejecting the classical understanding of the quantifiers in this area. At the same time, however, it places in doubt the admissibility of the knowability principle, which seems to involve quantification over the “totality” of truths. As Dummett is at pains to point out (1991: 316), some sentences that purport to quantify over the extension of an indefinitely extensible concept plainly have a truth-value (we can truly say, for example, that every ordinal number has a successor, even though when we say that we are not quantifying over the set of all ordinals). But is the knowability principle one of these sentences?

Chris Frith’s target chapters contain a wealth of interesting experiments and striking theoretical claims. In these comments I begin by drawing out some of the key themes in his discussion of action and the sense of agency. Frith’s central claim about conscious action is that what we are primarily conscious of in acting is our own agency. I will review some of the experimental evidence that he interprets in support of this claim and then explore the following three questions about the awareness of agency: Should we locate the phenomena that Frith describes as awareness of agency at the personal level or at the subpersonal level? If we are indeed operating at the personal level, then should we think about awareness of agency as something we experience, or as something that we believe? If awareness of agency is to be understood experientially, is there what some authors have called “a sense of agency”, where this is understood to be a distinctive type of experience that accompanies agentive behaviors but is absent in behaviors that are not under the control of the agent? In what follows I argue that awareness of agency should be located at the personal level, and that we should think of it as something we experience. But I will reject the claim that there is a distinctive sense of agency.

The existence of structures with non-trivial authomorphisms (such as the automorphism of the field of complex numbers onto itself that swaps the two roots of – 1) has been held by Burgess and others to pose a serious difficulty for mathematical structuralism. This paper proposes a model-theoretic solution to the problem. It suggests that mathematical structuralists identify the “position” of an n-tuple in a mathematical structure with the type of that n-tuple in the expansion of the structure that has a name for every element in it.
