    Is the relativity of simultaneity a temporal illusion?
    with K. Marlow
    Analysis 73 (4): 635-642. 2013.
    Tensism holds that the present moment has a special status that sets it apart from the past and the future, independently of perceivers. One of the main objections to this view has been Einstein’s argument from special relativity, which aims at showing that absolute simultaneity is a myth. We argue that the moving observer in a causal variant of Einstein’s original thought experiment is subject to a temporal illusion. Owing to the analogy of the cases, this casts doubt on the conjectures that th…Read more

    The paper argues that the English verb ‘to see’ can denote three different kinds of conscious states of seeing, involving visual experiences, visual seeming states and introspective seeming states, respectively. The case for the claim that there are three kinds of seeing comes from synesthesia and visual imagery. Synesthesia is a relatively rare neurological condition in which stimulation in one sensory or cognitive stream involuntarily leads to associated experiences in a second unstimulated st…Read more

    Strong representationalism and centered content
    Philosophical Studies 151 (3). 2010.
    I argue that strong representationalism, the view that for a perceptual experience to have a certain phenomenal character just is for it to have a certain representational content (perhaps represented in the right sort of way), encounters two problems: the dual looks problem and the duplication problem. The dual looks problem is this: strong representationalism predicts that how things phenomenally look to the subject reflects the content of the experience. But some objects phenomenally look to …Read more

    In his presidential address to the APA, ‘‘How to be an Anti-realist’’ (1982, 64–66), Alvin Plantinga argues that the only sensible way to be an antirealist is to be a theist.1 Anti-realism (AR) in this context is the epistemic analysis of truth that says, (AR) necessarily, a statement is true if and only if it would be believed by an ideally [or sufficiently] rational agent/community in ideal [or sufficiently good] epistemic circumstances. Plantinga demonstrates, with modest modal resources, tha…Read more

    Inscrutability and ontological commitment
    Philosophical Studies 141 (1). 2008.
    There are two doctrines for which Quine is particularly well known: the doctrine of ontological commitment and the inscrutability thesis—the thesis that reference and quantification are inscrutable. At first glance, the two doctrines are squarely at odds. If there is no fact of the matter as to what our expressions refer to, then it would appear that no determinate commitments can be read off of our best theories. We argue here that the appearance of a clash between the two doctrines is illusory…Read more

    In defense of hearing meanings
    Synthese 195 (7): 2967-2983. 2018.
    According to the inferential view of language comprehension, we hear a speaker’s utterance and infer what was said, drawing on our competence in the syntax and semantics of the language together with background information. On the alternative perceptual view, fluent speakers have a non-inferential capacity to perceive the content of speech. On this view, when we hear a speaker’s utterance, the experience confers some degree of justification on our beliefs about what was said in the absence of de…Read more

    Rapid advances in the field of neuroimaging techniques including magnetoencephalography (MEG), electroencephalography (EEG), functional MRI (fMRI), diffusion tensor imaging (DTI), voxel based morphomentry (VBM), and optical imaging, have allowed neuroscientists to investigate neural processes in ways that have not been possible until recently. Combining these techniques with advanced analysis procedures during different conditions such as hypnosis, psychiatric and neurological conditions, sublim…Read more

    Do Synesthetic Colors Grab Attention in Visual Search?
    with Kristian Marlow and Kevin Rice
    Review of Philosophy and Psychology 7 (4): 701-714. 2016.
    Recent research on synesthesia has focused on how the condition may depend on selective attention, but there is a lack of consensus on whether selective attention is required to bind colors to their grapheme inducers. In the present study, we used a novel change detection paradigm to examine whether synesthetic colors guide the subject’s attention to the location of the inducer or whether selective attention is required to act as a unique feature during visual search. If synesthetic experiences …Read more

    Perspectival truth and color primitivism
    In Cory D. Wright & Nikolaj J. L. L. Pedersen (eds.), New Waves in Truth, Palgrave-macmillan. pp. 1--34. 2010.
    Perspectivalism is a semantic theory according to which the contents of utterances and mental states (perhaps of a particular kind) have a truth-value only relative to a particular perspective (or standard) determined by the context of the speaker, assessor, or bearer of the mental state. I have defended this view for epistemic terms, moral terms and predicates of personal taste elsewhere (Brogaard 2008a, 2008b, forthcoming a). The main aim of this paper is to defend perspectivalism about color …Read more

    The Self-Locating Property Theory of Color
    Minds and Machines 25 (2): 133-147. 2015.
    The paper reviews the empirical evidence for highly significant variation across perceivers in hue perception and argues that color physicalism cannot accommodate this variability. Two views that can accommodate the individual differences in hue perception are considered: the self-locating property theory, according to which colors are self-locating properties, and color relationalism, according to which colors are relations to perceivers and viewing conditions. It is subsequently argued that on…Read more

    Disjunctivism
    Oxford Annotated Bibliographies Online. 2010.
    Naive realism is one of the oldest theories of perception. To a first approximation, naive realism is the view that perception is a direct relation between a subject and an object. Many historical philosophers (from Locke to Russell) argued that naive realism must be rejected on the grounds that hallucinations are perceptual experiences without an object. Contemporary philosophers have resurrected the theory by insisting that genuine cases of perception have a different structure or a different …Read more

    Perception and Its Objects

    In her response to my "Seeing as a Non-Experiental Mental State: The Case from Synesthesia and Visual Imagery" Ophelia Deroy presents an argument for an interesting new account of synesthesia. On this account, synesthesia can be thought of as "a perceptual state (e.g. of a letter)" that is "changed or enriched by the incorporation of a conscious mental image (e.g. a color)." I reply that while this is a plausible account of some types of synesthesia, some forms cannot be accounted for this way.

    Tr(A) iff ‡K(A) To remedy the error, Dummett’s proposes the following inductive characterization of truth: (i) Tr(A) iff ‡K(A), if A is a basic statement; (ii) Tr(A and B) iff Tr(A) & Tr(B); (iii) Tr(A or B) iff Tr(A) v Tr(B); (iv) Tr(if A, then B) iff (Tr(A) Æ Tr(B)); (v) Tr(it is not the case that A) iff ¬Tr(A), where the logical constant on the right-hand side of each biconditional clause is understood as subject to the laws of intuitionistic logic.2 The only other principle in play in Dummet…Read more

    Knowability, possibility and paradox
    In Vincent Hendricks (ed.), New Waves in Epistemology, Palgrave-macmillan. 2008.
    The paradox of knowability threatens to draw a logical equivalence between the believable claim that all truths are knowable and the obviously false claim that all truths are known. In this paper we evaluate prominent proposals for resolving the paradox of knowability. For instance, we argue that Neil Tennant’s restriction strategy, which aims principally to restrict the main quantifier in ‘all truths are knowable’, does not get to the heart of the problem since there are knowability paradoxes t…Read more

    The Long-Term Potentiation Model for Grapheme-Color Binding in Synesthesia
    with Kristian Marlow and Kevin Rice
    In David Bennett & Chris Hill (eds.), Sensory Integration and the Unity of Consciousness, Mit Press. 2015.
    The phenomenon of synesthesia has undergone an invigoration of research interest and empirical progress over the past decade. Studies investigating the cognitive mechanisms underlying synesthesia have yielded insight into neural processes behind such cognitive operations as attention, memory, spatial phenomenology and inter-modal processes. However, the structural and functional mechanisms underlying synesthesia still remain contentious and hypothetical. The first section of the present paper re…Read more

    The nature of the colors—what they are like, whether they are instantiated by objects or are projected by our minds, whether their nature is revealed to us in color perception, and whether there could be alien colors (e.g. reddish-green)—has been one of the central topics in philosophy for centuries. This entry focuses on the contemporary philosophical debate about the nature of the colors.

    According to the hierarchical model of sensory information processing, sensory inputs are transmitted to cortical areas, which are crucial for complex auditory and speech processing, only after being processed in subcortical areas (Hickok and Poeppel, 2007; Rauschecker and Scott, 2009). However, studies using electroencephalography (EEG) indicate that distinguishing simultaneous auditory inputs involves a widely distributed neural network, including the medial temporal lobe, which is essential f…Read more

    Studies have shown that both serotonin and glutamate receptor systems play a crucial role in the mechanisms underlying drug-induced synesthesia. The specific nature of these mechanisms, however, continues to remain elusive. Here we propose two distinct hypotheses for how synesthesia triggered by hallucinogens in the serotonin-agonist family may occur. One hypothesis is that the drug-induced destabilization of thalamic projections via GABAergic neuronal circuits from sensory areas leads to a disr…Read more

    Span operators

    I. Tensed Plural Quantifiers Presentists typically assent to a range of tensed statements, for instance, that there were dinosaurs, that there was a president named Lincoln, and that my future grandchildren will be on their way to school.1 Past- and future-tensed claims are dealt with by introducing primitive, intensional tense operators, for instance, it has been 12 years ago that, it was the case when I was born that, and it will be the case that (Prior 1968). For example, ‘there were dinosaur…Read more

    A partial defense of extended knowledge
    Philosophical Issues 24 (1): 39-62. 2014.
    The paper starts out by distinguishing two closely related hypotheses about extended cognition. According to the strong hypothesis, there are no intrinsic representations in the brain. This is a version of the extended-mind view defended by Andy Clark and Richard Menary. On the weak hypothesis, there are intrinsic representations in the brain but some types of cognition, knowledge or memory are constituted by particular types of external devices or environmental factors that extend beyond the sk…Read more

    Fitch's Paradox of Knowability
    The Stanford Encyclopedia of Philosophy. 2010.
    The paradox of knowability is a logical result suggesting that, necessarily, if all truths are knowable in principle then all truths are in fact known. The contrapositive of the result says, necessarily, if in fact there is an unknown truth, then there is a truth that couldn't possibly be known. More specifically, if p is a truth that is never known then it is unknowable that p is a truth that is never known. The proof has been used to argue against versions of anti-realism committed to the thes…Read more

    What do We Say When We Say How or What We Feel?
    Philosophers' Imprint 12. 2012.
    Discourse containing the verb ‘feel’, almost without exception, purports to describe inner experience. Though this much is evident, the question remains what exactly is conveyed when we talk about what and how we feel? Does discourse containing the word ‘feel’ actually succeed in describing the content and phenomenology of inner experience? If so, how does it reflect the phenomenology and content of the experience it describes? Here I offer a linguistic analysis of ‘feels’ reports and argue that…Read more
