At the end of the last century, Ernst Mach coined a term to describe a particular technique of scientific investigation, a mental analogue to physical experiment which he dubbed "Gedunkenexperiment."I According to Mach, this method is central to the history of science; its greatest practitioners include Aristotle and Galileo, and its careful employment "led to enormous changes in our thinking and to an opening up of most important new paths of inquiry."2 In the century that followed, Mach's term (and its (...) English translation) showed up occasionally in the philosophy of science literature, most notably, perhaps, in Karl Popper's "On the Use and Misuse of Imaginary Experiments, Especially in Quantum Theory,"s and in Thomas Kuhn's, "A Function for Thought Experiments."4 Discussions of the technique Ã¢â¬â in science and in philosophy Ã¢â¬â made sporadic appearances on the pages of philosophy journals, each year's Philosophers' Index sporting some dozen entries under "Thought Experiment." Then, in the mid-1980s, the Zeitgeist smiled upon thought experiments; they were explicitly recognized as a central technique in analytic philosophy, and self-conscious philosophical scrutiny was directed upon them.s In the Spring of 1986, Tamara Horowitz and Gerald Massey organized a conference at the University of Pittsburgh on "The Place of Thought Experiments in Science and Philosophy." The papers given at that conference, along with several others inspired by it, are collected in Thought Experiments in Science and Philosophy, published in 1991. A year later, Roy Sorensen published his Thought Experiments, a detailed ten-chapter discussion of thought experiments in philosophy and science, in which he defends their continuity with physical experiment, and adduces numerous arguments in favor of their philosophical legitimacy. Sorensen's style is chatty and unpretensious, full of striking turns of phrase and colloquialisms: "I am bullish on the comparison;" "this protoype gives us a bum steer;" "Wittgenstein discourages fascination with mental freak shows;" "traditional metaphysicians scoffed at Meinong's....

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.

To what extent and how is conceivability a guide to possibility? This essay explores general philosophical issues raised by this question, and critically surveys responses to it by Descartes, Hume, Kripke and "two-dimensionalists.".
It is a commonplace that contemplation of an imaginary particular may have cognitive and motivational effects that differ from those evoked by an abstract description of an otherwise similar state of affairs. In his Treatise on Human Nature, Hume ( 1978) writes forcefully of this.
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. (shrink)
The capacity to represent things to ourselves as possible plays a crucial role both in everyday thinking and in philosophical reasoning; this volume offers much-needed philosophical illumination of conceivability, possibility, and the relations between them.

Through careful analysis of a speciﬁc example, Parﬁt’s ‘ﬁssion argument’ for the unimportance of personal identity, I argue that our judgements concerning imaginary scenarios are likely to be unreliable when the scenarios involve disruptions of certain contingent correlations. Parﬁt’s argument depends on our hypothesizing away a number of facts which play a central role in our understanding and employment of the very concept under investigation; as a result, it fails to establish what Parﬁt claims, namely, that identity is not what (...) matters. I argue that Parﬁt’s conclusion can be blocked without denying that he has presented an imaginary case where prudential concern would be rational in the absence of identity. My analysis depends on the recognition that the features that explain or justify a relation may be distinct from the features that underpin it as necessary conditions. (shrink)
Regarding certain fictional characters (and situations) F, it is simultaneously true that: (1) We have genuine and rational emotional responses towards F (2) We believe that F is purely fictional At the same time, it is also true that: (3) In order for us to have genuine and rational emotional responses towards a character (or situation), we must not believe that the character (or situation) is purely fictional.
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.

By the age of two, children are able to engage in highly elaborate games of symbolic pretense, in which objects and actions in the actual world are taken to stand for objects and actions in a realm of make-believe. These games of pretense are marked by the presence of two central features, which I will call quarantining and mirroring (see also Leslie 1987; Perner 1991). Quarantining is manifest to the extent that events within the pretense-episode are taken to have effects (...) only within that pretense-episode (e.g. the child does not expect that ‘spilling’ ( pretend) ‘tea’1 will result in the table really being wet), or more generally, to the extent that proto-beliefs and proto-attitudes concerning the pretended state of affairs are not treated as beliefs and attitudes relevant to guiding action in the actual world. Mirroring is manifest to the extent that features of the imaginary situation that have not been explicitly stipulated are derivable via features of their real-world analogues (e.g. the child does expect that if she up-ends the teapot above the table, then the table will become wet in the pretense), or, more generally to the extent that imaginative content is taken to be governed by the same sorts of restrictions that govern believed content.

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.
Much contemporary discussion of perceptual experience can be traced to two observations. The first is that perception seems to put us in direct contact with the world around us: when perception is successful, we come to recognize— immediately—that certain objects have certain properties. The second is that perceptual experience may fail to provide such knowledge: when we fall prey to illusion or hallucination, the way things appear may differ radically from the way things actually are. For much of the twentieth (...) century, many of the most important discussions of perceptual experience could be fruitfully understood as responses to this pair of observations. (shrink)
It is of great use to the sailor to know the length of his line, though he cannot with it fathom all the depths of the ocean. It is well he knows that it is long enough to reach the bottom at such places as are necessary to direct his voyage, and caution him against running upon shoals that may ruin him.
The aim of this article is to expand the diet of examples considered in philosophical discussions of imagination and pretense, and to offer some preliminary observations about what we might learn about the nature of imagination as a result. The article presents a number of cases involving imaginative contagion: cases where merely imagining or pretending that P has effects that we would expect only perceiving or believing that P to have. Examples are offered that involve visual imagery, motor imagery, fictional (...) emotions, and social priming. It is suggested that imaginative contagion is a more prevalent phenomenon than has typically been recognized. (shrink)
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. (shrink)
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.

Millikan contrasts her substance-based view of concepts with “descriptionism” according to which description determines what falls under a concept. Focusing on her discussion of the role of language in the acquisition of concepts, I argue that descriptions cannot be separated from perception in the ways Millikan's view requires.
Following Karni's seminal work, Walker and other researchers have recently provided gradually convincing evidence that sleep is critical for the consolidation-based enhancement (CBE) of motor sequence learning. Studies in our laboratory using a motor adaptation paradigm, however, show that CBE can also occur after the simple passage of time, suggesting that sleep effects on memory consolidation are task-related, and possibly dependent on anatomically dissociable circuits.
