Forms of thinking that involve thinking about thought are only available to creatures participating in a public language. Thoughts can only be the objects of further thoughts if they have suitable vehicle and the only suitable vehicle is public language sentences. These language-dependent cognitive abilities range from second-order reflection on one's own beliefs and desires and the capacity to attribute thoughts to others to the ability to entertain tensed thoughts and to deploy logical concepts. Many of these language-dependent cognitive abilities, however, have primitive analogues that do not involve intentional ascent and hence are available at the nonlinguistic level. This chapter considers the practical implications this has for the scope and limits of nonlinguistic thought. The chapter explores the question: what types of thinking are in principle unavailable to nonlinguistic creatures? There are two types of intentional ascent, which might be termed explicit and implicit intentional ascent respectively.

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.

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 author challenges the view that birth cannot be a morally relevant fact in the process of development from zygote to child. He reviews specific arguments against giving any moral significance to the fact of birth. Drawing on recent work in developmental psychology, he contends that the lives of neonates can have a level of self-consciousness that confers moral significance but can only be possessed after birth. He shows that the position he has argued for provides a framework within which the move from the moral validity of aborting sentient fetuses to the moral validity of infanticide might be resisted. He concludes that arguments suggesting that birth can be morally significant support the view that the acquisition of moral significance is a gradual and multilayered phenomenon.

This paper explores the relation between two ways of thinking about the sources of self-consciousness. We can think about the sources of self-consciousness either in genetic terms (as the origins or precursors of self-conscious thoughts) or in epistemic terms (as the grounds of self-conscious judgements). Using Christopher Peacocke's account of self-conscious judgements in Being Known as a foil, this paper brings out some important ways in which we need to draw upon the sources of self-consciousness in the genetic sense for a proper understanding of the sources of self-consciousness in the epistemic sense.

This paper argues that, while there is a difference between personal and sub-personal explanation, claims of autonomy should be treated with scepticism. It distinguishes between horizontal and vertical explanatory relations that might hold between facts at the personal and facts at the sub-personal level. Noting that many philosophers are prepared to accept vertical explanatory relations between the two levels, I argue for the stronger claim that, in the case of at least three central personal level phenomena, the demands of explanatory adequacy require postulating horizontal explanatory relations.

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.

This paper explores Kornblith's proposal in "Knowledge and its Place in Nature" that knowledge is a natural kind that can be elucidated and understood in scientific terms. Central to Kornblith's development of this proposal is the claim that there is a single category of unreflective knowledge that is studied by cognitive ethologists and is the proper province of epistemology. This claim is challenged on the grounds that even unreflective knowledge in language-using humans reflects forms of logical reasoning that are in principle unavailable to nonlinguistic animals.

This article argues that bodily awareness is a basic form of self-consciousness through which perceiving agents are directly conscious of the bodily self. It clarifies the nature of bodily awareness, categorises the different types of body-relative information, and rejects the claim that we can have a sense of ownership of our own bodies. It explores how bodily awareness functions as a form of self-consciousness and highlights the importance of certain forms of bodily awareness that share an important epistemological property with canonical forms of self-consciousness such as introspection.
