What are hallucinations? A common view in the philosophical literature is that hallucinations are degenerate kinds of perceptual experience. I argue instead that hallucinations are degenerate kinds of sensory imagination. As well as providing a good account of many actual cases of hallucination, the view that hallucination is a kind of imagination represents a promising account of hallucination from the perspective of a disjunctivist theory of perception like naïve realism. This is because it provides a way of giving a positive (...) characterisation of hallucination—rather than characterising hallucinations in negative, relational, terms as mental events that are subjectively indistinguishable from veridical perceptual experiences.

Imagination has been assigned an important explanatory role in a multitude of philosophical contexts. This paper examines four such contexts: mindreading, pretense, our engagement with fiction, and modal epistemology. Close attention to each of these contexts suggests that the mental activity of imagining is considerably more heterogeneous than previously realized. In short, no single mental activity can do all the explanatory work that has been assigned to imagining.

Visual imagination (or visualization) is peculiar in being both free, in that what we imagine is up to us, and useful to a wide variety of practical reasoning tasks. How can we rely upon our visualizations in practical reasoning if what we imagine is subject to our whims? The key to answering this puzzle, I argue, is to provide an account of what constrains the sequence in which the representations featured in visualization unfold—an account that is consistent with its freedom. (...) Three different proposals are outlined, building on theories that link visualization to sensorimotor predictive mechanisms (e.g., efference copies, forward models ). Each sees visualization as a kind of reasoning, where its freedom consists in our ability to choose the topic of the reasoning. Of the three options, I argue that the approach many will find most attractive—that visualization is a kind of off-line perception, and is therefore in some sense misrepresentational—should be rejected. The two remaining proposals both conceive of visualization as a form of sensorimotor reasoning that is constitutive of one’s commitments concerning the way certain kinds of visuomotor scenarios unfold. According to the first, these commitments impinge on one’s web of belief from without, in the manner of normal perceptual experience; according to the second, these commitments just are one’s (occurrent) beliefs about such generalizations. I conclude that, despite being initially counterintuitive, the view of visualization as a kind of occurrent belief is the most promising. (shrink)

Remembering a cat sleeping (specifically, recollecting the way the cat looked), perceiving (specifically, seeing) a cat sleeping, and imagining (specifically, visualizing) a cat sleeping are of course importantly different. Nonetheless, from the first-person perspective they are palpably alike. The paper addresses two questions: Q1. What are these similarities (and differences)? Q2. How does one tell that one is recalling (and so not perceiving or imagining)?

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

What is it like to dream? On an orthodox view, dreams involve misleading sensations and false beliefs. I argue, on philosophical, psychological, and neurophysiological grounds, that orthodoxy about dreaming should be rejected in favor of an imagination model of dreaming. I am thus in partial agreement with Colin McGinn, who has argued that we do not have misleading sensory experiences while dreaming, and partially in agreement with Ernest Sosa, who has argued that we do not form false beliefs while dreaming. (...) Rather, on my view, dreams involve mental imagery and propositional imagination. I defend the imagination model of dreaming from objections. (shrink)

A standard view in the epistemology of imagination is that imaginings can either provide justification for modal beliefs about what is possible (and perhaps counterfactual conditionals too), or no justification at all. However, in a couple of recent articles, Kind (2016; Forthcoming) argues that imaginings can justify empirical belief about what the world actually is like. In this article, I respond to her argument, showing that imagination doesn't provide the right sort of information to justify empirical belief. Nevertheless, it can (...) help us take advantage of justification that we already have, thereby enabling us to form new doxastically justified beliefs. More specifically, according to the view I advocate, imagination can contribute to one's satisfaction of the proper basing condition – which turns propositional justification into doxastic justification – but without conferring any new justification that the subject isn't already in possession of upon their beliefs. Very little attention has been devoted to the distinction between propositional and doxastic justification in the literature on imagination, and the view I here argue for takes up a yet-to-be occupied position.

Imagination is necessary for scientific practice, yet there are no in vivo sociological studies on the ways that imagination is taught, thought of, or evaluated by scientists. This article begins to remedy this by presenting the results of a qualitative study performed on two systems biology laboratories. I found that the more advanced a participant was in their scientific career, the more they valued imagination. Further, positive attitudes toward imagination were primarily due to the perceived role of imagination in problem-solving. (...) But not all problem-solving episodes involved clear appeals to imagination, only maximally specific problems did. This pattern is explained by the presence of an implicit norm governing imagination use in the two labs: only use imagination on maximally specific problems, and only when all other available methods have failed. This norm was confirmed by the participants, and I argue that it has epistemological reasons in its favour. I also found that its strength varies inversely with career stage, such that more advanced scientists do (and should) occasionally bring their imaginations to bear on more general problems. A story about scientific pedagogy explains the trend away from (and back to) imagination over the course of a scientific career. Finally, some positive recommendations are given for a more imagination-friendly scientific pedagogy. (shrink)

Sometimes we learn through the use of imagination. The epistemology of imagination asks how this is possible. One barrier to progress on this question has been a lack of agreement on how to characterize imagination; for example, is imagination a mental state, ability, character trait, or cognitive process? This paper argues that we should characterize imagination as a cognitive ability, exercises of which are cognitive processes. Following dual process theories of cognition developed in cognitive science, the set of imaginative processes (...) is then divided into two kinds: one that is unconscious, uncontrolled, and effortless, and another that is conscious, controlled, and effortful. This paper outlines the different epistemological strengths and weaknesses of the two kinds of imaginative process, and argues that a dual process model of imagination helpfully resolves or clarifies issues in the epistemology of imagination and the closely related epistemology of thought experiments.

Many take the possibility of hallucinations to imply that a relationalist account, according to which perceptual experiences are constituted by direct relations to ordinary mind-independent objects, is false. The common reaction among relationalists is to adopt a disjunctivist view that denies that hallucinations have the same nature as perceptual experiences. This paper proposes a non-disjunctivist response to the argument from hallucination by arguing that the alleged empirical and a priori evidence in support of the possibility of hallucinations is inconclusive. A (...) corollary upshot of the article is that whether hallucinations are possible or not is still an open empirical question. (shrink)

The dissertation is in the format of a collection of several academic texts, composed of a two-part presentation and three papers on the topic of conceivability and the epistemology of modality. The presentation is composed of, first, a general introduction to conceivability theses and objections and, second, a discussion of two cases. Following the presentation, Asger provides three papers. The first paper, Pretense and Conceivability: A reply to Roca-Royes, presents a problem and a dilemma for Roca-Royes’ Non-Standard Dilemma for conceivability-based (...) epistemologies of de re modality in which she concludes that conceivability cannot be the whole story of our de re modal knowledge. The second paper, Conceivability Externalized, proposes an externalist conceivability-based epistemology of possibility inspired by Stalnaker. The third paper, Inconceivability as a Guide to Impossibility, considers inconceivability as an epistemic guide to impossibility, aiming to explore and add support to the underexplored thesis that one can justify beliefs about the impossibility of P on the basis of the inconceivability of P.

Enactivist (Embodied, Embedded, etc.) approaches in cognitive science and philosophy of mind are sometimes, though not always, conjoined with an anti-representational commitment. A weaker anti-representational claim is that ascribing representational content to internal/sub-personal processes is not compulsory when giving psychological explanations. A stronger anti-representational claim is that the very idea of ascribing representational content to internal/sub-personal processes is a theoretical confusion. This paper criticises some of the arguments made by Hutto & Myin (2013, 2017) for the stronger anti-representational claim and (...) suggests that the default Enactivist view should be the weaker non-representational position.

How are we to understand the phenomenology of imagining? Attempts to answer this question often invoke descriptors concerning the “vivacity” or “vividness” of our imaginative states. Not only are particular imaginings often phenomenologically compared and contrasted with other imaginings on grounds of how vivid they are, but such imaginings are also often compared and contrasted with perceptions and memories on similar grounds. Yet however natural it may be to use “vividness” and cognate terms in discussions of imagination, it does not (...) take much reflection to see that these terms are ill understood. In this paper, I review both some relevant empirical literature as well as the philosophical literature attempt to get a handle on what it could mean, in an imaginative context, to talk of vividness. As I suggest, this notion ultimately proves to be so problematic as to be philosophically untenable. (shrink)

The most salient aspect of memory is its role in preserving previously acquired information so as to make it available for further activities. Anna realizes that something is amiss in a book on Roman history because she learned and remembers that Caesar was murdered. Max turned up at the party and distinctively remembers where he was seated, so he easily gets his hands on his lost cell phone. The fact that information is not gained anew distinguishes memory from perception. The (...) fact that information is preserved distinguishes memory from imagination. But how do acquisition and retrieval of information contribute to the phenomenology of memory?The exclusive aim of this chapter is to sketch a map of the phenomenology of memory. It is structured as follows. In section 1, I introduce the contrast between content (what is remembered) and psychological attitude (remembering). This distinction will be helpful in disentangling issues in the phenomenology of memory. Section 2 is devoted to the contribution of memory content to phenomenology, section 3 to the contribution of the attitude of remembering. (shrink)

To what extent do I have a sense of agency over my thoughts while I dream? The sense of agency in dreams can alter in a variety of interesting ways distinct from normal, waking experience. In fact, dreams show many similarities to the experiences of individuals with schizophrenia. In this paper I analyze these alterations with a focus on distinguishing between reduced sense of agency and other cognitive features such as metacognition, confabulation and attention. I argue that some dream reports (...) demonstrate two interesting commonalities with schizophrenia: thought insertion (TI) and auditory hallucination (AH). This line of research has the potential to further our understanding of TI and AH in schizophrenia through the analysis of similar experience in a different conscious state. Through the analysis of dream reports, I found that although TI and AH both occur in dreams, TI is very rare. This is an interesting result since TI is common in patients with schizophrenia. I propose two speculative lines of explanation for the rarity of TI in dreams: first, the cognitive differences between the symptoms of schizophrenia and dreams, and second, the problem of dream reporting conditions. Dream reporting conditions are particularly important, as without controls, reports can be vague. Analysis of dream reports reveals that it is often unclear whether 'hearing voices' indicates sound phenomenology or thought phenomenology. I propose that dream reports could be disambiguated given the right experimental conditions and I suggest how this could be achieved in future experimental research. (shrink)

This metatheoretical paper develops a list of new research targets by exploring particularly promising interdisciplinary contact points between empirical dream research and philosophy of mind. The central example is the MPS-problem. It is constituted by the epistemic goal of conceptually isolating and empirically grounding the phenomenal property of “minimal phenomenal selfhood,” which refers to the simplest form of self-consciousness. In order to precisely describe MPS, one must focus on those conditions that are not only causally enabling, but strictly necessary to (...) bring it into existence. This contribution argues that research on bodiless dreams, asomatic out-of-body experiences, and full-body illusions has the potential to make decisive future contributions. Further items on the proposed list of novel research targets include differentiating the concept of a “first-person perspective” on the subcognitive level; investigating relevant phenomenological and neurofunctional commonalities between mind-wandering and dreaming; comparing the functional depth of embodiment across dream and wake states; and demonstrating that the conceptual consequences of cognitive corruption and systematic rationality deficits in the dream state are much more serious for philosophical epistemology (and, perhaps, the methodology of dream research itself) than commonly assumed. The paper closes by specifying a list of potentially innovative research goals that could serve to establish a stronger connection between dream research and philosophy of mind. (shrink)

In The Imaginary Sartre offers a systematic, insightful and heterodox account of imagining in many forms. Beginning with four ‘characteristics’ he takes to capture the phenomenology of imagining, he draws on considerations both philosophical and psychological to describe the deeper nature of the state that has those features. The result is a view that remains the most potent challenge to the Humean orthodoxy that to this day dominates both philosophical and psychological thinking on the topic.

Mental imagery has often been taken to be equivalent to “sensory imagination”, the perception‐like type of imagination at play when, for example, one visually imagines a flower when none is there, or auditorily imagines a music passage while wearing earplugs. I contend that the equation of mental imagery with sensory imagination stems from a confusion between two senses of mental imagery. In the first sense, mental imagery is used to refer to a psychological attitude, which is perception‐like in nature. In (...) the second sense, mental imagery refers to a mental content, which can be grasped via different attitudes. I will show that failure to acknowledge the distinction between these senses of mental imagery has muddled philosophical discussion. This distinction brings much needed clarity to debates where sensory imagination and mental imagery are invoked, shedding light on issues such as the nature of imagistic mental states, and the representational powers and limits of mental imagery. I will conclude by sketching a general attitudinal account of imagination that does justice to both senses of mental imagery, outlining a promising framework for understanding imagination. (shrink)

A widespread claim, which I call ‘the Emotionality Claim’, is that imagination but not supposition is intimately linked to emotion. In more cognitive jargon, imagination is connected to the affect system, whereas supposition is not. EC is open to several interpretations which yield very different views about the nature of supposition. The literature lacks an in-depth analysis of EC which sorts out these different readings and ways to carve supposition and imagination at their joints. The aim of this paper is (...) to fill this gap. I shall argue that existing readings of EC fail to properly account for the emotional asymmetry between imagination and supposition. The tendency is to start from narrow conceptions of both imagination and supposition. I shall argue for a novel interpretation of EC pivoting on different ways a mental state can connect to the affect system. (shrink)

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

According to the additive view of sensory imagination, mental imagery often involves two elements. There is an image-like element, which gives the experiences qualitative phenomenal character akin to that of perception. There is also a non-image element, consisting of something like suppositions about the image's object. This accounts for extra- sensory features of imagined objects and situations: for example, it determines whether an image of a grey horse is an image of Desert Orchid, or of some other grey horse. The (...) view promises to give a simple and intuitive explanation of some puzzling features of imagination, and, further, to illuminate imagination 's relation to modal knowledge. I contend that the additive view does not fulfil these two promises. The explanation of how images come to be determinate is redundant: the content constituting the indeterminate mental images on which the view relies is sufficient to deliver determinate images too, so the extra resources offered by the view are not required..

In this essay I seek to show that a philosophy of modesty informs core aspects of both Nietzsche’s critique of morality and what he intends to replace morality with, namely, an ethics of self-cultivation. To demonstrate this I focus on Dawn: Thoughts on the Prejudices of Morality, a largely neglected text in his corpus where Nietzsche carries out a quite wide-ranging critique of morality, including Mitleid. It is one of Nietzsche’s most experimental works and is best read, I claim, as (...) an Epicurean-inspired critique of the present and an exercise in moral therapy. In the opening sections I draw attention to the wider social dimension of the text and its concern with a morality of compassion, which is rarely done in the literature. I then turn to highlighting Nietzsche’s Epicurean moment, followed by two sections on Nietzsche on the self in which I aim to bring to light his ethics of self-cultivation and show in what ways his revaluation makes central to ethics a modest egoism and care of self. In the conclusion to the essay I provide a contrast between Nietzsche and Kant and deal with reservations readers might have about his ethics. Overall, the essay seeks to make a contribution to an appreciation of Dawn as a work of moral therapy. (shrink)

The tuning-fork model of human social cognition, based on the discovery of mirror neurons (MNs) in the ventral premotor cortex of monkeys, involves the four following assumptions: (1) mirroring processes are processes of resonance or simulation. (2) They can be motor or non-motor. (3) Processes of motor mirroring (or action-mirroring), exemplified by the activity of MNs, constitute instances of third-person mindreading, whereby an observer represents the agent's intention. (4) Non-motor mirroring processes enable humans to represent others' emotions. After questioning all (...) four assumptions, I point out that MNs in an observer's brain could not synchronically resonate with MNs in an agent's brain unless they discharged in a single brain in two distinct tasks at different times. Finally, I sketch a conceptualist alternative to the resonance model according to which a brain mechanism active in both the execution and the perception of e.g., the act of grasping is the neural basis of the concept of e.g., grasping.

This paper addresses the following questions: what account should be given of the state of wakeful consciousness, and what explanatory roles should be assigned to that state? Those questions are taken up after some discussion of the related but distinct question of what it is to be awake. On the view proposed here, in seeking to provide an account of the state of wakeful consciousness one should be aiming to provide an account of a point of view that is associated (...) with the distinctive form of awareness to which one surfaces when one wakes up. Our specification of that point of view should appeal to the awake subject’s temporal point of view, and the epistemic orientation and agential perspective it embodies. The explanatory roles that can be assigned to the state of wakeful consciousness are the explanatory roles that can be assigned to that point of view. (shrink)

Sextus Empiricus offers an underappreciated and under-discussed version of dream-based skepticism. Most philosophers interested in dreams and skepticism focus on the question of how you know you are not currently dreaming. Sextus points out that our waking experiences and dreams often conflict. And, the challenge goes, what reason do you have to trust the one over the other? This question presupposes that dreams and waking experiences are distinguishable. Thus the kinds of responses typically offered against dream-based skepticism do not apply. (...) And if we accept an idea upheld by one camp in the contemporary debate over the epistemology of disagreement, Sextus’ challenge is difficult to answer. A G.E. Moore-inspired response to the problem is also proposed and explored. It is argued that Sextus’ version of the problem reveals a certain limitation in that sort of approach to skeptical problems.
