Direct realists think that we can't get a clear view the nature of /hallucinating a white picket fence/: is it /representing a white picket fence/? is it /sensing white-picket-fencily/? is it /being acquainted with a white' picketed' sense-datum/? These are all epistemic possibilities for a single experience; hence they are all metaphysical possibilities for various experiences. Hallucination itself is a disjunctive or "multidisjunctive" category. I rebut MGF Martin's argument from statistical explanation for his "epistemic" conception of hallucination, but his view (...) embeds in my view as a "reference-fixer". (shrink)

Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. (...) I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly. (shrink)

My purpose is to take a close look at the nature of visual content. I discuss the view that visual experiences have only existential contents, the view that visual experiences have either singular or gappy contents, and the view that visual experiences have multiple contents. I also consider a proposal about visual content inspired by Kaplan's well known theory of indexicals. I draw out some consequences of my discussion for the thesis of intentionalism with respect to the phenomenal character of (...) visual experience. (shrink)

Traditional models of skill learning posit that skilled action unfolds in an automatic manner and that control will prove deleterious to movement and performance proficiency. These perspectives assume that automated processes are characterised by low levels of control and vice versa. By contrast, a number of authors have recently put forward hybrid theories of skilled action which have sought to capture the close integration between fine-grained automatic motor routines and intentional states. Drawing heavily on the work of Bebko et al. (...) and Christensen et al., we argue that controlled and automated processes must operate in parallel if skilled performers are to address the wide range of challenges that they are faced with in training and competition. More specifically, we show how skilled performers use controlled processes to update and improve motor execution in training contexts and to stabilise performance under pressurised conditions.

In this paper, I describe and criticize M.G.F. Martin's version of disjunctivism, and his argument for it from premises about self-knowledge.

I develop a view of perception that does justice to Price's intuition that all sensory experience acquaints us with sensible qualities like colour and shape. Contrary to the received opinion, I argue that we can respect this intuition while insisting that ordinary perception puts us in direct contact with the mind-independent world. In other words, Price's intuition is compatible with naïve realism. Both hallucinations and ordinary perceptions acquaint us with instances of the same kinds of sensible qualities. While the instances (...) in hallucination are mind-dependent, those in veridical perception are not. The latter are ontologically over-determined —they have their existence guaranteed both in virtue of having a material bearer and in virtue of being perceived by a mind. Such over-determined instances are mind-independent—they can continue to exist unperceived, because, in addition to the minds that perceive them, their existence is guaranteed by the material objects that are their bearers.

I argue that any account of perceptual experience should satisfy the following two desiderata. First, it should account for the particularity of perceptual experience, that is, it should account for the mind-independent object of an experience making a difference to individuating the experience. Second, it should explain the possibility that perceptual relations to distinct environments could yield subjectively indistinguishable experiences. Relational views of perceptual experience can easily satisfy the first but not the second desideratum. Representational views can easily satisfy the (...) second but not the first desideratum. I argue that to satisfy both desiderata perceptual experience is best conceived of as fundamentally both relational and representational. I develop a view of perceptual experience that synthesizes the virtues of relationalism and representationalism, by arguing that perceptual content is constituted by potentially gappy de re modes of presentation.

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and brain stimulation). (...) They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

Questions about perception remain some of the most difficult and insoluble in both epistemology and in the philosophy of mind. This controversial but highly accessible introduction to the area explores the philosophical importance of those questions by re-examining what had until recent times been the most popular theory of perception - the sense-datum theory. Howard Robinson surveys the history of the arguments for and against the theory from Descartes to Husserl. He then shows that the objections to the theory, particularly (...) Wittgenstein's attack on privacy and those of the physicalists, have been unsuccessful. He argues that we should return to the theory sense-data in order to understand perception. In doing so he seeks to overturn a consensus that has dominated the philosophy of perception for nearly half a century. (shrink)

Develops an empirical argument against naive realism-disjunctivism: if naive realists accept "internal dependence", then they cannot explain the evolution of perceptual success. Also presents a puzzle about our knowledge of universals.

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt any (...) particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist view of time, (...) and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past.

The disjunctive theory of perception claims that we should understand statements about how things appear to a perceiver to be equivalent to statements of a disjunction that either one is perceiving such and such or one is suffering an illusion (or hallucination); and that such statements are not to be viewed as introducing a report of a distinctive mental event or state common to these various disjoint situations. When Michael Hinton first introduced the idea, he suggested that the burden of (...) proof or disproof lay with his opponent, that what was needed was to show that our talk of how things look or appear to one..

Many philosophers are skeptical about disjunctivism —a theory of perceptual experience which holds roughly that a situation in which I see a banana that is as it appears to me to be and one in which I have a hallucination as of a banana are mentally completely different. Often this skepticism is rooted in the suspicion that such a view cannot adequately account for the bad case—in particular, that such a view cannot explain why what it’s like to have a (...) hallucination can be exactly like what it’s like to have a veridical experience, that it cannot explain why the hallucination I have in the bad case is subjectively indistinguishable from the kind of experience I have in the good case, and that it cannot offer a viable account of the nature of hallucination. -/- In this paper, I argue that a proper formulation of disjunctivism can avoid these objections. Disjunctivism should be formulated as the weakest claim required to preserve its primary motivation, viz., Naïve Realism—the view that veridical experience fundamentally consists in the subject perceiving entities in her environment. And the weakest claim required to preserve Naïve Realism allows for many sorts of commonalities across the good and hallucinatory cases, commonalities that can be marshaled in responding to the objections. Most importantly, disjunctivism properly formulated is compatible with “positive” accounts of the nature of hallucination. (shrink)

Like dreaming, hallucination has been a formative trope for modern philosophy. The vivid, often tragic, breakdown in the mind’s apparent capacity to disclose reality has long served to support a paradoxical philosophical picture of sensory experience. This picture, which of late has shaped the paradigmatic empirical understanding the senses, displays sensory acts as already complete without the external world; complete in that the direct objects even of veridical sensory acts do not transcend what we could anyway hallucinate. Hallucination is thus (...) the mother of Representationalism, which insists that it is mental intermediaries that make other.. (shrink)

[John Hawthorne] We examine some well-known disjunctivist projects in the philosophy of perception, mainly in a critical vein. Our discussion is divided into four parts. Following some introductory remarks, we examine in part two the link between object-dependent contents and disjunctivism. In part three, we explore the disjunctivist's use of discriminability facts as a basis for understanding experience. In part four, we examine an interesting argument for disjunctivism that has been offered by Michael Martin. /// [Scott Sturgeon] The paper aims (...) to do five things: sketch the backbone of disjunctivism about visual experience, explore the view of our title, defend a version of that view from two objections, press two more objections of my own, and sketch a more radical variety of disjunctivism which avoids much of the bother.

John Foster addresses the question: what is it to perceive a physical object? He rejects the view that we perceive such objects directly, and argues for a new version of the traditional empiricist account, which locates the immediate objects of perception in the mind. But this account seems to imply that we do not perceive physical objects at all. Foster offers a surprising solution, which involves embracing an idealist view of the physical world.

Abstract: How exactly should the relation between a veridical perception and a corresponding hallucination be understood? I argue that the epistemic notion of ‘indiscriminability’, understood as lacking evidence for the distinctness of things, is not suitable for defining this relation. Instead, we should say that a hallucination and a veridical perception involve the same phenomenal properties. This has further consequences for attempts to give necessary and sufficient conditions for the identity of phenomenal properties in terms of indiscriminability, and for considerations (...) about the phenomenal sorites.

John Campbell investigates how consciousness of the world explains our ability to think about the world; how our ability to think about objects we can see depends on our capacity for conscious visual attention to those things. He illuminates classical problems about thought, reference, and experience by looking at the underlying psychological mechanisms on which conscious attention depends.
