How should we react to the contention that there is empirical evidence showing that many judge Gettier cases to be cases of knowledge, contrary to the verdict of most analytical philosophers about these cases? I argue that there is no single answer to this question. The discussion is set inside a view about how to view the role and significance of intuitive responses to some of philosophy's famous thought experiments. One take-home message is that experimental philosophy and conceptual analysis are (...) not as far apart as is often thought. (shrink)

The modal fictionalist faces a problem due to the fact that her chosen story seems to be incomplete—certain things are neither fictionally true nor fictionally false. The significance of this problem is not localized to modal fictionalism, however, since many fictionalists will face it too. By examining how the fictionalist should analyze the notion of truth according to her story, and, in particular, the role that conditionals play for the fictionalist, I develop a novel and elegant solution to the incompleteness (...) problem.

A story does more than recount events; it recounts events in a way that renders them intelligible, thus conveying not just information but also understanding. We might therefore be tempted to describe narrative as a genre of explanation. When the police invite a suspect to “tell his story,” they are asking him to explain the blood on his shirt or his absence from home on the night of the murder; and whether he is judged to have a “good story” will (...) depend on its adequacy as an explanation. Can we account for the explanatory force of narrative with the models of explanation available in the philosophy of science? Or does narrative convey a different kind of understanding, which requires a different model and perhaps even a term other than ‘explanation’? (shrink)

Many important metaphysical arguments validly deduce an actuality from a possibility. For example: Because it is possible for me to exist in the absence of anything material, I am not my body. I argue that there is no reason to suppose that our capacity for modal judgment is equal to the task of determining whether the "possibility" premise of any of these arguments is true. I connect this thesis with Stephen Yablo's recent work on the epistemology of modal statements.

Recent accounts of pretense have been underdescribed in a number of ways. In this paper, we present a much more explicit cognitive account of pretense. We begin by describing a number of real examples of pretense in children and adults. These examples bring out several features of pretense that any adequate theory of pretense must accommodate, and we use these features to develop our theory of pretense. On our theory, pretense representations are contained in a separate mental workspace, a Possible (...) World Box which is part of the basic architecture of the human mind. The representations in the Possible World Box can have the same content as beliefs. Indeed, we suggest that pretense representations are in the same representational ``code'' as beliefs and that the representations in the Possible World Box are processed by the same inference and UpDating mechanisms that operate over real beliefs. Our model also posits a Script Elaborator which is implicated in the embellishment that occurs in pretense. Finally, we claim that the behavior that is seen in pretend play is motivated not from a ``pretend desire'', but from a real desire to act in a way that ®ts the description being constructed in the Possible World Box. We maintain that this account can accommodate the central features of pretense exhibited in the examples of pretense, and we argue that the alternative accounts either can't accommodate or fail to address entirely some of the central features of pretense. q 2000 Elsevier Science B.V.

What happens to a person in a case of fission? Does it survive? Does it go out of existence? Or is the outcome indeterminate? Since each description of fission based on the persistence conditions associated with our ordinary concept of a person seems to clash with one or more platitudes of common sense about the spatiotemporal profile of macroscopic objects, fission threatens the common-sense conception of persons with inconsistency. Standard responses to this paradox agree that the common-sense conception of persons (...) is unstable, differing over which part of the conception requires revision. I will show that this entrenched view of fission is not compulsory. I will develop a solution to the paradox that maintains the consistency of the common-sense conception of persons on the basis of an ontology of persons and other ordinary objects as double-layered compounds. Each of various descriptions of the outcome of personal fission is compatible with principles about the spatiotemporal profile of persons, because the descriptions and the principles manifest different perspectives on persons and are made true or false by different ontological components of the latter. What holds for the fission of persons, holds for the fission of other kinds of objects. (shrink)

This paper motivates, explains, and defends a new account of the content of thought experiments. I begin by briefly surveying and critiquing three influential accounts of thought experiments: James Robert Brown’s Platonist account, John Norton’s deflationist account that treats them as picturesque arguments, and a cluster of views that I group together as mental model accounts. I use this analysis to motivate a set of six desiderata for a new approach. I propose that we treat thought experiments primarily as aesthetic (...) objects, specifically fictions, and then use this analysis to characterize their content and ultimately assess their epistemic success. Taking my starting point from Kendall Walton’s account of representation (Mimesis as make-believe, Harvard University Press, Cambridge, 1990), I argue that the best way to understand the content of thought experiments is to treat them as props for imagining fictional worlds. Ultimately, I maintain that, in terms of their form and content, thought experiments share more with literary fictions and pictorial representations than with either argumentation or observations of the Platonic realm. Moreover, while they inspire imaginings, thought experiments themselves are not mental kinds. My approach redirects attention towards what fixes the content of any given thought experiment and scrutinizes the assumptions, cognitive capacities and conventions that generate them. This view helps to explain what seems plausible about Brown’s, Norton’s, and the mental modelers’ views. (shrink)

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

Imaginative immersion refers to a phenomenon in which one loses oneself in make-believe. Susanna Schellenberg says that the best explanation of imaginative immersion involves a radical revision to cognitive architecture. Instead of there being an attitude of belief and a distinct attitude of imagination, there should only be one attitude that represents a continuum between belief and imagination. -/- We argue otherwise. Although imaginative immersion is a crucial data point for theorizing about the imagination, positing a continuum between belief and (...) imagination is neither necessary nor sufficient for explaining the phenomenon. In addition, arguing against Schellenberg’s account reveals important but underappreciated lessons for theorizing about the imagination and for interpreting boxological representations of the mind.

I criticize Timothy Williamson's characterization of thought experiments on which the central judgments are judgments of contingent counterfactuals. The fragility of these counterfactuals makes them too easily false, and too difficult to know.

In this essay, then, I would like to address what I believe are the most compelling epistemic arguments against the notion that literature (and art more broadly) can function as an instrument of education and a source of knowledge.

Recently, philosophers have discovered that they have a lot to learn from, or at least to ponder about, fiction. Many metaphysicians are attracted to fiction as a model for our talk about purported objects and properties, such as numbers, morality, and possible worlds, without embracing a robust Platonist ontology. In addition, a growing group of philosophers of mind are interested in the implications of our engagement with fiction for our understanding of the mind and emotions: If I don’t believe that (...) Anna Karenina exists, can I really pity her, or hope or desire that she extricate herself from her tragic situation? And why is there no “morality fiction,” analogous to science fiction? I suspect that philosophers have been especially comfortable thinking about fiction because it seems, at least prima facie, to employ the imagination in a way that conforms to a standard model of the mind. Specifically, contemporary philosophers tend to think of imagination as a form of mental pretense. Mental pretense can take two main forms: a cognitive attitude of supposing a set of propositions to be true (make-believe) or else an experiential state of imaging a scenario as if it were before one (imaging). Much of our pretense intertwines the cognitive and experiential modalities, of course. But both share a crucial common feature: all of one’s imaginative effort is invested in pretending that certain contents obtain. In this sense, we can understand imagination as the “offline” simulation of actual beliefs and perceptions (and perhaps other attitudes as well), where we analyze these in the normal way, as states individuated by their attitude and representational content. While I share the burgeoning interest in fiction, I want to suggest that we also have a lot to learn from poetry, and in particular from poetic metaphor. I will argue.. (shrink)

Fictional truth is commonly analyzed in terms of the speech acts or propositional attitudes of a teller. In this paper, I investigate Lewis’s counterfactual analysis in terms of felicitous narrator assertion, Currie’s analysis in terms of fictional author belief, and Byrne’s analysis in terms of ideal author invitations to make-believe—and find them all lacking. I propose instead an analysis in terms of the revelations of an infelicitous narrator.
