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.

By carefully examining one of the most famous thought experiments in the history of science—that by which Galileo is said to have refuted the Aristotelian theory that heavier bodies fall faster than lighter ones—I attempt to show that thought experiments play a distinctive role in scientific inquiry. Reasoning about particular entities within the context of an imaginary scenario can lead to rationally justified concluusions that—given the same initial information—would not be rationally justifiable on the basis of a straightforward argument.

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.

The Elements of Philosophy: Readings from Past and Present is a comprehensive collection of historical and contemporary readings across the major fields of philosophy. With depth and quality, this introductory anthology offers a selection of readings that is both extensive and expansive; the readings span twenty-five centuries. They are organized topically into five parts: Religion and Belief, Moral and Political Philosophy, Metaphysics and Epistemology, Philosophy of Mind and Language, and Life and Death. The product of the collaboration of three highly respected scholars in their fields - Tamar Szabó Gendler, Susanna Siegel, and Steven M. Cahn - The Elements of Philosophy also includes introductions from the editors, explanatory footnotes, and a glossary.

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.

In the last few years there has been an explosion of philosophical interest in perception; after decades of neglect, it is now one of the most fertile areas for new work. Perceptual Experience presents new work by fifteen of the world's leading philosophers. All papers are written specially for this volume, and they cover a broad range of topics dealing with sensation and representation, consciousness and awareness, and the connections between perception and knowledge and between perception and action. This will be the book on the philosophy of perception, a fascinating resource for philosophers and psychologists.

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.

Contemplating imaginary scenarios that evoke certain sorts of quasi‐sensory intuitions may bring us to new beliefs about contingent features of the natural world. These beliefs may be produced quasi‐observationally; the presence of a mental image may play a crucial cognitive role in the formation of the belief in question. And this albeit fallible quasi‐observational belief‐forming mechanism may, in certain contexts, be sufficiently reliable to count as a source of justification. This sheds light on the central puzzle surrounding scientific thought experiment, which is how contemplation of an imaginary scenario can lead to new knowledge about contingent features of the natural world.
