This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if they (...) are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

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.

Ira Brevis furor, said the Latins: anger is a brief bout of madness. There is a long tradition that views all emotions as threats to rationality. The crime passionnel belongs to that tradition: in law it is a kind of “brief-insanity defence.” We still say that “passion blinds us;” and in common parlance to be philosophical about life's trials is to be decently unemotional about them. Indeed many philosophers have espoused this view, demanding that Reason conquer Passion. Others — from (...) Hume to the Emotivists — have appeared to reverse this hierarchy.” But those philosophers who refuse to join in the general denigration of emotion as irrational usually share the presupposition that the role of rationality is limited to the calculation of means. In so far as emotions are concerned with the determination of ends, they remain, on this view, beyond the pale of rationality. Modern decision theorists have worked out schemes to assess the rationality of desires, as well as actions, against the background of beliefs and other desires.1 But these schemes leave no room at all for emotions, except, by implication, as disrupters of the rational process.

Conceptual features differ in how mentally tranformable they are. A robin that does not eat is harder to imagine than a robin that does not chirp. We argue that features are immutable to the extent that they are central in a network of dependency relations. The immutability of a feature reflects how much the internal structure of a concept depends on that feature; i.e., how much the feature contributes to the concept's coherence. Complementarily, mutability reflects the aspects in which a (...) concept is flexible. We show that features can be reliably ordered according to their mutability using tasks that require people to conceive of objects missing a feature, and that mutability (conceptual centrality) can be distinguished from category centrality and from diagnosticity and salience. We test a model of mutability based on asymmetric, unlabeled, pairwise dependency relations. With no free parameters, the model provides reasonable fits to data. Qualitative tests of the model show that mutability judgments are unaffected by the type of dependency relation and that dependency structure influences judgments of variability. (shrink)

According to recent accounts of the imagination, mental mechanisms that can take input from both imagining and from believing will process imagination‐based inputs (pretense representations) and isomorphic beliefs in much the same way. That is, such a mechanism should produce similar outputs whether its input is the belief that p or the pretense representation that p. Unfortunately, there seem to be clear counterexamples to this hypothesis, for in many cases, imagining that p and believing that p have quite different psychological (...) consequences. This paper sets out some central problem cases and argues that the cases might be accommodated by adverting to the role of desires concerning real and imaginary situations. (shrink)

We are prone to gross error, even in favorable circumstances of extended reflection, about our own ongoing conscious experience, our current phenomenology. Even in this apparently privileged domain, our self-knowledge is faulty and untrustworthy. We are not simply fallible at the margins but broadly inept. Examples highlighted in this essay include: emotional experience (for example, is it entirely bodily; does joy have a common, distinctive phenomenological core?), peripheral vision (how broad and stable is the region of visual clarity?), and the (...) phenomenology of thought (does it have a distinctive phenomenology, beyond just imagery and feelings?). Cartesian skeptical scenarios undermine knowledge of ongoing conscious experience as well as knowledge of the outside world. Infallible judgments about ongoing mental states are simply banal cases of self-fulfillment. Philosophical foundationalism supposing that we infer an external world from secure knowledge of our own consciousness is almost exactly backward. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Against Ethical CriticismRichard A. PosnerOscar Wilde famously remarked that “there is no such thing as a moral or an immoral book. Books are well written, or badly written. That is all.” He was echoed by Auden, who said in his poem in memory of William Butler Yeats that poetry makes nothing happen (though the poem as a whole qualifies this overstatement), by Croce, and by formalist critics such as (...) Cleanth Brooks, a doyen of the New Critics, who insisted that edification was the function of religion but not of poetry. 1 George Orwell, though himself a didactic novelist, was of this view as well, 2 and it is one that most critics adopt when the issue is censorship. I accept Wilde’s thesis—the creed of aestheticism, of art for art’s sake—if understood to mean that the moral content and consequences of a work of literature are irrelevant to its value as literature; or as the critic Helen Vendler has put it, that “treating fictions as moral pep-pills or moral emetics is repugnant to anyone who realizes the complex psychological and moral motives of a work of art.” 3 This is not to deny that reading can have consequences, including moral and political ones. Information affects people’s outlook and behavior, and reading is a source of information. Imaginative literature conveys ideas, opinions, and information, often with great power. Think of the role that novels by Turgenev (Fathers and Sons), Dostoevsky (The Possessed), Conrad (The Secret Agent, Under Western Eyes), Koestler (Darkness at Noon), Orwell (Animal Farm, Nineteen Eighty-Four), and, of course, Solzhenitsyn played in exposing the horrors of anarchism and communism. Of A Passage to India it has been said that “as an account of the social conditions of British India it was powerful enough to have influenced events.” 4 Upton Sinclair’s novel The Jungle is thought to have incited federal regulation of food processing; and few doubt the effect of Uncle Tom’s Cabin (1852) on the abolitionist cause. [End Page 1]At the core of the aesthetic tradition, which I shall be defending in this essay particularly against its opponents in the “law and literature” movement, are three theses. First, immersion in literature does not make us better citizens or better people. One might be able to pick out some works of literature that would have such an effect because of the information they convey or the emotional state they induce, but they would constitute a skewed sample of literary works. Second, we should not be put off by morally offensive views encountered in literature even when the author appears to share them. A work of literature is not to be considered maimed or even marred by expressing unacceptable moral views; by the same token, a mediocre work of literature is not redeemed by expressing moral views of which we approve. The proper criteria for evaluating literature are aesthetic rather than ethical. Third, authors’ moral qualities or opinions should not affect our valuations of their works.The insistence, in short, is on the separation of the moral from the aesthetic—but with two qualifications. Some literature has little interest or value apart from the didactic and for it the proper criticism is didactic. And the separation of moral from aesthetic values is not a rejection of the former. The aesthetic outlook is a moral outlook, one that stresses the values of openness, detachment, hedonism, curiosity, tolerance, the cultivation of the self, and the preservation of a private sphere—in short, the values of liberal individualism.The counter tradition in literary criticism to the aesthetic originates with Plato and insists upon the importance, in some versions to the near or even total exclusion of anything else, of the ethical or political content and effects of works of literature, and less commonly of the author’s own morality. Martha Nussbaum, for example, deems Greek tragedies and Anglo-American realistic novels a part of moral philosophy. 5 Reading novels, she argues, “develops moral capacities without which citizens will not succeed in making reality out of the normative conclusions of any moral or political theory, however excellent.” 6 Wayne Booth, disagreeing with his illustrious...

Recent cognitive accounts of the imagination propose that imagining and believing are in the same “code”. According to the single code hypothesis, cognitive mechanisms that can take input from both imagining and from believing will process imagination-based inputs (“pretense representations”) and isomorphic beliefs in much the same way. In this paper, I argue that the single code hypothesis provides a unified and independently motivated explanation for a wide range of puzzles surrounding fiction.

We experience resistance when we are engaging with fictional works which present certain (for example, morally objectionable) claims. But in virtue of what properties do sentences trigger this ‘imaginative resistance’? I argue that while most accounts of imaginative resistance have looked for semantic properties in virtue of which sentences trigger it, this is unlikely to give us a coherent account, because imaginative resistance is a pragmatic phenomenon. It works in a way very similar to Paul Grice's widely analysed ‘conversational implicature’.

One way in which the characteristic gestures of philosophy and criticism differ from each other lies in their involvements with disillusionment, with the undoing of our naivete, especially regarding what we take ourselves to know about the meaning of what we say. Philosophy will often find less than we thought was there, perhaps nothing at all, in what we say about the “external” world, or in our judgments of value, or in our ordinary psychological talk. The work of criticism, on (...) the other hand, frequently disillusions by finding disturbingly more in what is said than we precritically thought was there. In our relation to the meaningfulness of what we say, there is a disillusionment of plentitude as well as of emptiness. And no doubt what is “less” for one discipline may be “more” of what someone else is looking for.In recent years, metaphor has attracted more than its share of both philosophical and critical attention, including philosophical denials of the obvious, as well as critical challenges to the obviousness of the ways we talk about metaphor. In this paper I discuss a problem of each sort and suggest a complex of relations between them. The particular denial of the obvious that I’m interested in is the claim recently made by Donald Davidson that “a metaphor doesn’t say anything beyond its literal meaning ,” nor is it even correct to speak of metaphor as a form of communication.1 There’s disillusionment with a vengeance; and even if not strictly believable, it is still not without its therapeutic value, as we shall see. 1. Donald Davidson, “What Metaphors Mean,” in On Metaphor, ed. Sheldon Sacks , p. 30; hereafter abbreviated “WMM.” Davidson’s view has found supporters among both philosophers and literary theorists. It is, for example, important to the early argument of Richard Rorty’s recent book. See his Contingency, Irony, and Solidarity , p. 18. Richard Moran is an assistant professor of philosophy at Princeton University. He is currently working on a book on subjectivity and contemporary concepts of personhood. (shrink)

Imaginative resistance refers to a phenomenon in which people resist engaging in particular prompted imaginative activities. On one influential diagnosis of imaginative resistance, the systematic difficulties are due to these particular propositions’ discordance with real-world norms. This essay argues that this influential diagnosis is too simple. While imagination is indeed by default constrained by real-world norms during narrative engagement, it can be freed with the power of genre conventions and expectations.

The paper plays against the philosophical stereotype that facts are bits of reality, ‘furniture of the universe’, and that values in contrast are either mysterious bits of reality or responses to facts. It follows Strawson in regarding facts as interpretative constructs. Values also are interpretative constructs, characterized by a normal (but not universal) connection with motivations. So is there a deep difference? There is a sense of ‘facts’, marked by phrases such as ‘Stick to the facts’, in which the interpretative (...) element embedded in a ‘fact’ is uncontentious and would be invisible to most people. The interpretative element in values, in contrast, usually is very noticeable. But values in which this element comes to be uncontentious and taken for granted congeal into facts. (shrink)

Philosophers often call emotions appropriate or inappropriate. What is meant by such talk? In one sense, explicated in this paper, to call an emotion appropriate is to say that the emotion is fitting: it accurately presents its object as having certain evaluative features. For instance, envy might be thought appropriate when one’s rival has something good which one lacks. But someone might grant that a circumstance has these features, yet deny that envy is appropriate, on the grounds that it is (...) wrong to be envious. These two senses of ‘appropriate’ have much less in common than philosophers have supposed. Indeed, the distinction between propriety and correctness is crucial to understanding the distinctive role of the emotions in ethics. We argue here that an emotion can be fitting despite being wrong to feel, and that various philosophical arguments are guilty of a systematic error which we term the moralistic fallacy. (shrink)

Early Greek philosophers doubled as natural scientists; that is a common-place. It is equally true, though less often remarked, that numerous historical philosophers doubled as cognitive scientists. They constructed models of mental faculties in much the spirit of modern cognitive science, for which they are widely cited as precursors in the cognitive science literature. Today, of course, there is more emphasis on experiment, and greater division of labor. Philosophers focus on theory, foundations, and methodology, while cognitive scientists are absorbed by (...) experimental techniques and findings. Nonetheless, there are sound reasons for massive communication between philosophy and cognitive science, which happily proceeds apace. On this occasion I shall not try to enumerate or delineate these lines of communication in any comprehensive fashion. I just wish to illustrate the benefits to philosophy in two domains: the theory of mind and moral theory. Though this may sound like an ambitious agenda, I shall in fact examine just a single phenomenon: empathy. Using that term first broadly and later narrowly,I shall argue that empathy may be the key to one sector of the philosophy of mind and to several sectors of moral theory. But whether empathy can in fact unlock any doors depends heavily on the outcome of empirical research in cognitive science. (shrink)

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)

I argue that judgments of what is ‘true in a fiction’ presuppose the Reality Assumption: the assumption that everything that is true is fictionally the case, unless excluded by the work. By contrast with the more familiar Reality Principle, the Reality Assumption is not a rule for inferring implied content from what is explicit. Instead, it provides an array of real-world truths that can be used in such inferences. I claim that the Reality Assumption is essential to our ability to (...) understand stories, drawing on a range of empirical evidence that demonstrates our reliance on it in narrative comprehension. However, the Reality Assumption has several unintuitive consequences, not least that what is fictionally the case includes countless facts that neither authors nor readers could ever consider. I argue that such consequences provide no reason to reject the Reality Assumption. I conclude that we should take fictions, like non-fictions, to be about the real world. (shrink)

In one sense, explicated in this paper, to call an emotion appropriate is to say that the emotion is fitting: it accurately presents its object as having certain evaluative features.

What can we learn from fiction? I argue that we can learn about the consequences of a certain course of action by projecting ourselves, in imagination, into the situation of the fiction's characters.

Metaphors are powerful communicative tools because they produce ”framing effects’. These effects are especially palpable when the metaphor is an insult that denigrates the hearer or someone he cares about. In such cases, just comprehending the metaphor produces a kind of ”complicity’ that cannot easily be undone by denying the speaker’s claim. Several theorists have taken this to show that metaphors are engaged in a different line of work from ordinary communication. Against this, I argue that metaphorical insults are rhetorically (...) powerful because they combine perspectives, presupposition, and pragmatics in the service of speech acts with assertoric force.

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)

We should not admit categorial restrictions on the significance of syntactically well formed strings. Syntactically well formed but semantically absurd strings, such as ‘Life’s but a walking shadow’ and ‘Caesar is a prime number’, can express thoughts; and competent thinkers both are able to grasp these and ought to be able to. Gareth Evans’ generality constraint, though Evans himself restricted it, should be viewed as a fully general constraint on concept possession and propositional thought. For (a) even well formed but (...) semantically cross-categorial strings often do possess substantive inferential roles; (b) hearers exploit these inferential roles in interpreting such strings metaphorically; (c) there is no good reason to deny truth-conditions to strings with inferential roles.

Philosophers have traditionally inclined toward one of two opposite extremes when it comes to metaphor. On the one hand, partisans of metaphor have tended to believe that metaphors do something different in kind from literal utterances; it is a ‘heresy’, they think, either to deny that what metaphors do is genuinely cognitive, or to assume that it can be translated into literal terms. On the other hand, analytic philosophers have typically denied just this: they tend to assume that if metaphors (...) express any genuine content at all, then that content can in principle be paraphrased into literal terms. They often conclude on this basis that metaphor is theoretically dispensable, and so that it poses no special challenges and affords no distinctive insights for the philosophy of language and mind.

Three studies test eight hypotheses about (1) how judgment differs between people who ascribe greater vs. less moral relevance to choices, (2) how moral judgment is subject to task constraints that shift evaluative focus (to moral rules vs. to consequences), and (3) how differences in the propensity to rely on intuitive reactions affect judgment. In Study 1, judgments were affected by rated agreement with moral rules proscribing harm, whether the dilemma under consideration made moral rules versus consequences of choice salient, (...) and by thinking styles (intuitive vs. deliberative). In Studies 2 and 3, participants evaluated policy decisions to knowingly do harm to a resource to mitigate greater harm or to merely allow the greater harm to happen. When evaluated in isolation, approval for decisions to harm was affected by endorsement of moral rules and by thinking style. When both choices were evaluated simultaneously, total harm -- but not the do/allow distinction -- influenced rated approval. These studies suggest that moral rules play an important, but context-sensitive role in moral cognition, and offer an account of when emotional reactions to perceived moral violations receive less weight than consideration of costs and benefits in moral judgment and decision making.

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.
