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.

A fiction may prescribe imagining that a pig can talk or tell the future. A fiction may prescribe imagining that torturing innocent persons is a good thing. We generally comply with imaginative prescriptions like the former, but not always with prescriptions like the latter: we imagine non-evaluative fictions without difficulty but sometimes resist imagining value-rich fictions. Thus arises the puzzle of imaginative resistance. Most analyses of the phenomenon focus on the content of the relevant imaginings. The present analysis focuses instead (...) on the character of certain kinds of imaginings, arguing that we resist in such cases given the rich evaluative character of the imaginings prescribed, and the agent-dependent constraints on imagining in such ways.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

This paper explores the sense in which belief "aims at the truth". In this course of this exploration, it discusses the difference between belief and make-believe, the nature of psychoanalytic explanation, the supposed "normativity of meaning", and related topics.

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim , from there to a modal claim , and from there to a metaphysical claim.

How should we understand the emotional rationality? This first part will explore two models of cognition and analogy strategies, test their intuition about the emotional desire. I distinguish between subjective and objective desire, then presents with a feeling from the "paradigm of drama" export semantics, here our emotional repertoire is acquired all the learned, and our emotions in the form of an object is fixed. It is pretty well in line with the general principles of rationality, especially the lowest reasonable (...) principles. Turned to the second part of this side of reasonable. I will inquire how emotional beliefs, desires, and behaviors contribute to the rationality. I will present a very general biological hypothesis: emotions by controlling highlights the characteristics of perception and reasoning, so that we remove the difficulties due in particular to lead to paralysis; they are being simulated by a simplified perception of information, thus limiting our practice and cognitive choice. How are we to understand emotional or axiological rationality? I pursue analogies with both the cognitive and the strategic models, testing them against intuitions about emotional desires. We distinguish two different classes of desires, the subjective and the objective, and propose that emotions have a semantics that derives from "paradigmatic scenarios", in terms of which our emotional repertoire is learned and the formal objects of our emotions fixed. This fits in well with emerging facts about how our emotional capacities develop, and it can also be squared with the general principles of rationality, particularly minimal rationality. In the second part, I return to the perspective of rationality. I ask how emotions contribute to the rationality of beliefs, desires, and behavior. I proffer a very general biological hypothesis: Emotions spare us the paralysis potentially induced by a particular predicament by controlling the salience of features of perception and reasoning; they temporarily mimic the informational encapsulation of perception and so circumscribe our practical and cognitive options.

Keith Oatley draws on theories from psychology, philosophy and linguistics, as well as writings from other social sciences, to show how emotions are central to any understanding of human actions and mental life.

One version of the Humean Theory of Motivation holds that all actions can be causally explained by reference to a belief–desire pair. Some have argued that pretense presents counter-examples to this principle, as pretense is instead causally explained by a belief-like imagining and a desire-like imagining. We argue against this claim by denying imagination the power of motivation. Still, we allow imagination a role in guiding action as a script . We generalize the script concept to show how things besides (...) imagination can occupy this same role in both pretense and non-pretense actions. The Humean Theory of Motivation should then be modified to cover this script role. (shrink)

Many traditional theories of creativity put heavy emphasis on an incubation stage in creative cognitive processes. The basic phenomenon is a familiar one: we are working on a task or problem, we leave it aside for some period of time, and when we return attention to the task we have some new insight that services completion of the task. This feature, combined with other ostensibly mysterious features of creativity, has discouraged naturalists from theorizing creativity. This avoidance is misguided: we can (...) maintain unconscious incubated cognition as (sometimes) part of the creative process and we can explain it in scientifically responsible ways. This paper, focusing on the effects of attention on the functional networking of the brain, attempts just such an explanation. It also serves to assuage the naturalist's scepticism about other features of creative cognition. The broad upshot, one would hope, is that philosophers of mind and cognitive scientists return some attention to the long neglected topic of creativity. (shrink)

Pictures are principally descriptive. Advertising images highlight features of potential purchases; cartoons open portals to scenes in fictional worlds; snapshots in the family photo album remind us of our past selves and landmark events in our personal histories; works of pictorial art express thoughts or feelings about depicted scenes. In addition, pictures serve a directive or action-guiding function that, though not taken into account by theorists, deserves no less attention than their descriptive one. Theories of depiction and the appreciation of (...) pictures stand to benefit by taking "directive pictures" into account, as do theories of representation in general and mental representation in particular.

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.

Despite their intuitive appeal and a long philosophical history, imagery-based accounts of the imagination have fallen into disfavor in contemporary discussions. The philosophical pressure to reject such accounts seems to derive from two distinct sources. First, the fact that mental images have proved difficult to accommodate within a scientific conception of mind has led to numerous attempts to explain away their existence, and this in turn has led to attempts to explain the phenomenon of imagining without reference to such ontologically (...) dubious entities as mental images. Second, even those philosophers who accept mental images in their ontology have worried about what seem to be fairly obvious examples of imaginings that occur without imagery. In this paper, I aim to relieve both these points of philosophical pressure and, in the process, develop a new imagery-based account of the imagination: the imagery model. (shrink)

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.
