901Multisensory Consciousness and SynesthesiaIn Berit Brogaard & Elijah Chudnoff (eds.), Routledge Handbook of Consciousness, Routledge. pp. 322-336. 2020.This chapter distinguishes between two kinds of ordinary multisensory experience that go beyond mere co-consciousness of features (e.g., the experience that results from concurrently hearing a sound in the hallway and seeing the cup on the table). In one case, a sensory experience in one modality creates a perceptual demonstrative to whose referent qualities are attributed in another sensory modality. For example, when you hear someone speak, auditory experience attributes audible qualities to …Read more

546The Publicity of Meaning and the Perceptual Approach to Speech ComprehensionProtoSociology 34 144-162. 2017.The paper presents a number of empirical arguments for the perceptual view of speech comprehension. It then argues that a particular version of phenomenal dogmatism can confer immediate justification upon belief. In combination, these two views can bypass Davidsonian skepticism toward knowledge of meanings. The perceptual view alone, however, can bypass a variation on the Davidsonian argument. One reason Davidson thought meanings were not truly graspable was that he believed meanings were privat…Read more

860Against Emotional DogmatismPhilosophical Issues 26 (1): 59-77. 2016.It may seem that when you have an emotional response to a perceived object or event that makes it seem to you that the perceived source of the emotion possesses some evaluative property, then you thereby have prima facie, immediate justification for believing that the object or event possesses the evaluative property. Call this view ‘dogmatism about emotional justification’. We defend a view of the structure of emotional awareness according to which the objects of emotional awareness are derived…Read more

77Introduction: Epistemic ModalsTopoi 36 (1): 127-130. 2017.Theorists with otherwise radically different commitments agree that epistemic modals mark the necessity or possibility of a prejacent proposition relative to a body of evidence or knowledge. However, there is vast disagreement about the semantics of epistemic modals, which stems in part from the fact that statements of epistemic possibility or necessity make no explicit reference to a speaker or group, an audience, or an evidence set. This volume introduces new philosophical papers that mark a s…Read more

1Temporal MereologyDissertation, State University of New York at Buffalo. 2000.This work explores the problem of the persistence of objects through change, given the assumption that objects are three-dimensional entities; and the continuation of events through time, given the assumption that events are four-dimensional entities. My main concern is to provide an informative metaphysical grounding of temporal continuation by identifying the primitive relations and properties into which this concept can be analyzed. My thesis is that entities a and b can be said to be the sam…Read more

328Sechzehn Tage: Wann beginnt ein menschliches Leben?In Guido Imaguire & Christine Schneider (eds.), Untersuchungen zur Ontologie, Philosophia. pp. 3-40. 2006.Der Abschluß der Gastrulation, der gleichzeitig auch den Anfang der Neurulation bedeutet, ist die zeitliche Grenze, die Beginn eines menschlichen Individuums markiert. Oft wird behauptet, daß jegliche natürliche Veränderung stetig ist. Wie ist es dann aber möglich, eine zeitliche Grenze auszuzeichnen, an der ein menschliches Lebewesen zu existieren beginnt? Man beachte, was geschieht, wenn wir vom Thema zeitlicher Unstetigkeit zum räumlichen übergehen. Lebewesen haben räumliche Grenzen (wie sie …Read more

215Information may be defined as the conceptual or communicable part of the content of mental acts. The content of mental acts includes sensory data as well as concepts, particular as well as general information. An information system is an external (non-mental) system designed to store such content. Information systems afford indirect transmission of content between people, some of whom may put information into the system and others who are among those who use the system. In order for communicatio…Read more

1068The Ontology of Fields (edited book)National Center for Geographic Information and Analysis. 1998.In the specific case of geography, the real world consists on the one hand of physical geographic features (bona fide objects) and on the other hand of various fiat objects, for example legal and administrative objects, including parcels of real estate, areas of given soil types, census tracts, and so on. It contains in addition the beliefs and actions of human beings directed towards these objects (for example, the actions of those who work in land registries or in census bureaux), and the rela…Read more

66Pre-cueing, Perceptual Learning and Cognitive PenetrationFrontiers in Psychology 8. 2017.In The Principles of Psychology, William James (1981) has long ago suggested that attending to a stimulus can make it appear more ‘vivid and clear.’ Pre-cueing, the procedure in which a cue stimulus is presented to direct a subject’s attention to the location of a test stimulus, has been used to test James’ hypothesis (Posner, 1978; Carrasco et al., 2004; Carrasco, Loula, & Ho, 2006; Yeshurun & Rashal, 2010; Carrasco, 2011). One recent debate concerns whether the effects of pre-cueing and other …Read more

657Unconscious Imagination and the Mental Imagery DebateFrontiers in Psychology 8. 2017.Traditionally, philosophers have appealed to the phenomenological similarity between visual experience and visual imagery to support the hypothesis that there is significant overlap between the perceptual and imaginative domains. The current evidence, however, is inconclusive: while evidence from transcranial brain stimulation seems to support this conclusion, neurophysiological evidence from brain lesion studies (e.g., from patients with brain lesions resulting in a loss of mental imagery but n…Read more

480The but not all: A partitive account of plural definite descriptionsMind and Language 22 (4). 2007.A number of authors in favor of a unitary account of singular descriptions have alleged that the unitary account can be extrapolated to account for plural definite descriptions. In this paper I take a closer look at this suggestion. I argue that while the unitary account is clearly onto something right, it is in the end empirically inadequate. At the end of the paper I offer a new partitive account of plural definite descriptions that avoids the problems with both the unitary account and standar…Read more

411Contextualism, skepticism, and the Gettier problemSynthese 139 (3). 2004.The contextualist epistemological theories proposed by David Lewis and othersoffer a view of knowledge which awards a central role to the contexts ofknowledge attributions. Such contexts are held to determine how strong anepistemic position must be in order to count as knowledge. Lewis has suggestedthat contextualism so construed can be used both to ward off the skeptic and tosolve the Gettier problem. A person knows P, he says, just in case her evidenceeliminates every possibility that not-P, w…Read more

771Knowledge-how: A unified accountIn J. Bengson & M. Moffett (eds.), Knowing How: Essays on Knowledge, Mind, and Action, Oxford University Press. pp. 136-160. 2011.There are two competing views of knowledge-how: Intellectualism and anti-intellectualism. According to the reductionist varieties of intellectualism defended by Jason Stanley and Timothy Williamson (2001) and Berit Brogaard (2007, 2008, 2009), knowledge-how simply reduces to knowledge-that. To a first approximation, s knows how to A iff there is a w such that s knows that w is a way to A. For example, John knows how to ride a bicycle if and only if there is a way w such that John knows that w is…Read more

131Seeing Mathematics: Perception and Brain Activity in a Case of Acquired SynesthesiaNeurocase. forthcoming.We studied the patient JP who has exceptional abilities to draw complex geometrical images by hand and a form of acquired synesthesia for mathematical formulas and objects, which he perceives as geometrical figures. JP sees all smooth curvatures as discrete lines, similarly regardless of scale. We carried out two preliminary investigations to establish the perceptual nature of synesthetic experience and to investigate the neural basis of this phenomenon. In a functional magnetic resonance imaging…Read more

1131Consciousness and KnowledgeIn Uriah Kriegel (ed.), The Oxford Handbook of the Philosophy of Consciousness, Oxford University Press. 2020.This chapter focuses on the relationship between consciousness and knowledge, and in particular on the role perceptual consciousness might play in justifying beliefs about the external world. We outline a version of phenomenal dogmatism according to which perceptual experiences immediately, prima facie justify certain select parts of their content, and do so in virtue of their having a distinctive phenomenology with respect to those contents. Along the way we take up various issues in connection…Read more

705The so-called Meno problem is one of the recent trendy topics in epistemology.1 In a nutshell, the Meno problem is that of explaining why we value knowledge more than true belief. In his recent book The Value of Knowledge and the Pursuit of Understanding Jon Kvanvig argues quite convincingly that no existing account of knowledge can accommodate the intuition that the value of knowledge exceeds the value of true belief.

390Non-Visual Consciousness and Visual Images in BlindsightConsciousness and Cognition 21 (1): 595-596. 2012.In a recent response paper to Brogaard (2011a), Morten Overgaard and Thor Grünbaum argue that my case for the claim that blindsight subjects are not visually conscious of the stimuli they correctly identify rests on a mistaken necessary criterion for determining whether a conscious experience is visual or non-visual. Here I elaborate on the earlier argu- ment while conceding that the question of whether blindsight subjects are visually con- scious of the visual stimuli they correctly identify la…Read more

304Sea Battle SemanticsPhilosophical Quarterly 58 (231). 2008.The assumption that the future is open makes well known problems for traditional semantics. According to a commonly held intuition, today's occurrence of the sentence 'There will be a sea battle tomorrow', while truth-valueless today, will have a determinate truth-value by tomorrow night. Yet given traditional semantics, sentences that are truth-valueless now cannot later 'become' true. Relativistic semantics has been claimed to do a better job of accommodating intuitions about future contingent…Read more

414A Puzzle about PropertiesPhilosophy and Phenomenological Research 74 (3): 635-650. 2007.The paper argues that the assumption that there are property designators, together with two theoretically innocent claims, leads to a puzzle, whose solution requires us to reject the position that all (canonical) property designators are rigid. But if we deny that all (canonical) property designators are rigid, then the natural next step is to reject an abundant conception of properties and with it the suggestion that properties are the semantic values of predicates.

830Are There Unconscious Perceptual Processes?Consciousness and Cognition 20 (2): 449-63. 2011.Blindsight and vision for action seem to be exemplars of unconscious visual processes. However, researchers have recently argued that blindsight is not really a kind of uncon- scious vision but is rather severely degraded conscious vision. Morten Overgaard and col- leagues have recently developed new methods for measuring the visibility of visual stimuli. Studies using these methods show that reported clarity of visual stimuli correlates with accuracy in both normal individuals and blindsight pa…Read more
