In this paper I will present a puzzle about visual appearance. There are certain necessary constraints on how things can visually appear. The puzzle is about how to explain them. I have no satisfying solution. My main thesis is simply that the puzzle is a puzzle. I will develop the puzzle as it arises for representationalism about experience because it is currently the most popular theory of experience and I think it is along the right lines. However, everyone faces a (...) form of the puzzle, including the naïve realist. In §1 I explain representationalism about experience. In §§2-3 I develop the puzzle and criticize a response due to Ned Block and Jeff Speaks and another response based on a novel form of representationalism (“sensa representationalism”). In §4 I argue that defenders of “perceptual confidence” (Morrison, Munton, my earlier self) face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

Intentionalism debates seek to uncover the relationship between the qualitative aspects of experience—phenomenal character—and the intentionality of the mind. They have been at or near center stage in the philosophy of mind for more than two decades, and in my view need to be reexamined. There are two core distinct intentionalism debates that are rarely distinguished (Sect. 1). Additionally, the characterization of spectrum inversion as involving inverted qualities and constant intentional content is mistaken (Sect. 3). These confusions can be witnessed (...) from an often-ignored and lonely perspective, that of the sense-datum theorist, and in particular of the projectivist (Sect. 2). In my view we have been so wary of sense-datum theory in recent years that we have failed to see that, even if false, it may permit perspectives on intentionalism issues difficult to occupy from other views.

In his Problems of Philosophy, Bertrand Russell distinguished knowledge by acquaintance and knowledge of truths. This paper argues for a new interpretation of the relationship between these two species of knowledge. I argue that knowledge by acquaintance of an object neither suffices for knowledge that one is acquainted with the object, nor puts a subject in a position to know that she is acquainted with the object. These conclusions emerge from a thorough examination of the central role played by attention (...) in Russell's theory of knowledge. Attention bridges the gap between knowledge by acquaintance and our capacity to form judgements about the objects of acquaintance. (shrink)

Moritz Schlick’s work shaped Logical Empiricism and thereby an important part of philosophy in the first half of the 20th century. A continuous thread that runs through his work is a philosophical diagnosis of the ‘great errors in philosophy’: philosophers assume that there is intuitive knowledge/knowledge by acquaintance. Yet acquaintance, it is not knowledge, but an evaluative attitude. In this paper I will reconstruct Schlick’s arguments for this conclusion in the light of his early practical philosophy and his reading of (...) Schopenhauer’s The World as Will and Idea. Having the historical roots of Schlick’s position in view will put us in a position to explore and question its presuppositions. (shrink)

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.

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

Is the sense-data theory, otherwise known as indirect realism, a form of representationalism? This question has been underexplored in the extant literature, and to the extent that there is discussion, contemporary authors disagree. There are many different variants of representationalism, and differences between these variants that some people have taken to be inconsequential turn out to be key factors in whether the sense-data theory is a form of representationalism. Chief among these are whether a representationalist takes the phenomenal character of (...) an experience to be explicable in virtue of the properties of an experience that represent something or explicable in virtue of that which gets represented. Another is whether representationalists hold a non-reductionist, or naturalistically or non-naturalistically reductionist variant of representationalism. In addition, subtle differences in what one takes phenomenal character to be on the sense-data theory – either awareness of sense-data or the sense-data themselves – together with one's account of representation, are crucial factors in determining whether sense-data theory is compatible with representationalism. This paper explores these relationships and makes manifest the complexities of the metaphysics of two central theories of perception. (shrink)

My question is: does phenomenal consciousness have a critical role in explaining the way conscious perceptions achieve objective import? I approach it through developing a dilemma I label ‘Burge’s Challenge’, which is implicit in his approach to perceptual objectivity. It says, crudely: either endorse the general structure of his account of how objective perceptual import is achieved, and give up on a role for consciousness. Or, relinquish Caused Representation, and possibly defend a role for consciousness. Someone I call Burge* holds (...) we should embrace the first horn of the dilemma. A second response, roughly the relationalist approach, opts for the second horn. The third option, implicit in many current approaches to perceptual consciousness, is to reject the dilemma. The paper argues for a version of the second response. The key argument turns on the development of a sceptical challenge to justify the assumption that we perceive particular intrinsic property instantiations, rather than their structural equivalents. The suggestion will be that only the relationalist approach can meet it in the way we think it is met. If this is right, there is a prima facie case for taking relationalist responses to the dilemma seriously. I end with two objections to this response, which might be made by the real Burge in defence of opting for the first horn of the dilemma, and by phenomenal intentionalists in defence of rejecting the dilemma. I use discussion of these to highlight one of the main issues that should be pursued in order to make good the claim that we should embrace the horn of the dilemma that Burge* rejects. (shrink)

The causal theory of perception has come under a great deal of critical scrutiny from philosophers of mind interested in the nature of perception. M. H. Newman's set-theoretic objection to Russell's structuralist version of the CTP, in his 1928 paper “Mr Russell's Causal Theory of Perception” has not, to my knowledge, figured in these discussions. In this paper I aim to show that it should: Newman's objection can be generalized to yield a particularly powerful and incisive challenge to all versions (...) of the CTP. In effect it says that if the CTP is true, at least one of the following claims must be false. Our perception-based judgements are made true or false by the state of mind independent objects. The concepts we use in such judgments refer to the intrinsic, mind-independent properties of such objects. Experience provides us with knowledge of these properties. The paper sets out the structure of the problem as Newman saw it, extends it to current debates in theory of perception and considers various responses to it. The response I argue for involves jettisoning the CTP in favour of a relational account of perceptual experience, in a way that allows us to hold onto all three claims. (shrink)

One increasingly popular view in the philosophy of perception isexternalismabout sensible qualities, according to which sensible qualities such as colors, smells, tastes, and textures are features, not of our minds, but of mind-independent, external objects in the world. The primary motivation for this view is that perceptual experience seems to betransparent—that is, when we attend to sensible qualities, it seems like what we are attending to are features of external objects, not our own minds. Most (if not all) externalists are (...) either naïve realists or externalist representationalists. However, in this article, I argue that those who are moved by the primary motivation for externalism should instead be sense-datum theorists, for externalists’ primary motivation supports the sense-datum theory, not their actually favored views. I argue that externalists should focus on different motivations, get new ones, or become sense-datum theorists. (shrink)
