I introduce and argue for the importance of a cognitive state that I call alief. An alief is, to a reasonable approximation, an innate or habitual propensity to respond to an apparent stimulus in a particular way. Recognizing the role that alief plays in our cognitive repertoire provides a framework for understanding reactions that are governed by nonconscious or automatic mechanisms, which in turn brings into proper relief the role played by reactions that are subject to conscious regulation and deliberate control.

ln "Possibilities and the Arguments for Origin Essentialism" Teresa Robertson (1998) contends that the best-known arguments in favour of origin essentialism can succeed only at the cost of violating modal common sense—by denying that any variation in constitution or process of assembly is possible. Focusing on the (Kripke-style) arguments of Nathan Salmon and Graeme Forbes, Robertson shows that both founder in the face of sophisticated Ship of Theseus style considerations. While Robertson is right that neither of the arguments is compelling as formulated, each can be modified to fend off her particular counterexamples; these modifications do not differ in kind from those already needed to deal with ordinary Theseus cases, requiring only a further narrowing of the sufficiency clause from which the necessity of origins is derived.

Oxford Studies in Epistemology is a biennial publicaton which offers a regular snapshot of state-of-the-art work in this important field. Under the guidance of a distinguished editorial board composed of leading philosophers in North America, Europe and Australasia, it will publish exemplary papers in epistemology, broadly construed. Topics within its purview include: *traditional epistemological questions concerning the nature of belief, justification, and knowledge, the status of scepticism, the nature of the a priori, etc; *new developments in epistemology, including movements such as naturalized epistemology, feminist epistemology, social epistemology, and virtue epistemology, and approaches such as contextualism; *foundational questions in decision-theory; *confirmation theory and other branches of philosophy of science that bear on traditional issues in epistemology; *topics in the philosophy of perception relevant to epistemology; *topics in cognitive science, computer science, developmental, cognitive, and social psychology that bear directly on traditional epistemological questions; and *work that examines connections between epistemology and other branches of philosophy, including work on testimony and the ethics of belief. Anyone wanting to understand the latest developments at the leading edge of the discipline can start here.

“Like much recent work on personal identity,” Carol Rovane writes in the opening sentence of The Bounds of Agency: An Essay in Revisionary Metaphysics, “this effort takes its main cue from Locke”. The work also—as its title suggests—takes inspiration from Strawsonian neo-Kantianism. And although direct allusion to his writings is limited to a few passing references, Rovane’s essay is largely Davidsonian in spirit. Indeed, it would not be an exaggeration to say that The Bounds of Agency answers a question about personal identity by providing a transcendental analysis of the conditions for personhood whose analysans turns out to be a commitment to agency. In situating the work within such an intellectual context, I do not mean to cast aspersions on its originality; there is no question that Rovane offers a tremendously innovative and sophisticated account of personal identity. But it may be helpful for readers approaching the book on the basis of its title to realize at the outset that it is neither a work of analytic metaphysics, nor a work concerned with the internal structure of agency. Rather, The Bounds of Agency offers a sustained exploration of the preconditions and implications of taking seriously a particular conception of personhood that uniquely satisfies a cluster of methodological constraints that should be accepted by all parties in the debate concerning the nature of persons and the conditions that govern their identity over time. According to such a conception, what distinguishes persons from other sorts of beings is their capacity to engage in agency-regarding relations. What underpins that capacity is a commitment to rational agency, that is, a commitment to achieving overall rational unity. So, argues Rovane, what it is to be a person is to be committed to acting upon all-things-considered judgments in rationally optimal ways. And what it is for a person to persist over time is for certain sorts of rational relations to hold among certain sorts of intentional episodes, in ways that allow the commitments of the person at one time to govern the intentional actions of a person at another.

I had a structural worry about the relation of Gaita’s three chapters on truth, interesting though these chapters are, to the rest of Gaita’s project. And I had some residual questions left after reading the book: What are persons? How do we know when we are encountering one, and when are we justified (we must be sometimes: compare the various sorts of animal) in a decision that something we encounter is not a person? Do evil actions always involve a sort of blindness to what is being done? If so, how easy is it to explain how agents who do evil can be held responsible for their cognitive deficiencies? These may of course be questions that Gaita was not trying to answer; but in any case, as I hope I have conveyed, I found A Common Humanity a striking and revelatory read, and I warmly recommend it.

Issues of pretense and imagination are of central interest to philosophers, psychologists, and researchers in allied fields. In this entry, we provide a roadmap of some of the central themes around which discussion has been focused. We begin with an overview of pretense, imagination, and the relationship between them. We then shift our attention to the four specific topics where the disciplines' research programs have intersected or where additional interactions could prove mutually beneficial: the psychological underpinnings of performing pretense and of recognizing pretense, the cognitive capacities involved in imaginative engagement with fictions, and the real-world impact of make-believe. In the final section, we discuss more briefly a number of other mental activities that arguably involve imagining, including counterfactual reasoning, delusions, and dreaming.
