Do the physical facts of the viewed environment account for the ordinary experiences we have of that environment? According to standard philosophical views, distal facts do account for our experiences, a phenomenon explained by appeal to perceptual constancy, the phenomenal stability of objects and environmental properties notwithstanding physical changes in proximal stimulation. This essay reviews a significant but neglected research tradition in experimental psychology according to which percepts systematically do not correspond to mind-independent distal facts. Instead, stability of percept values (...) comes in degrees, and physical facts about the viewed environment alone do not account for our ordinary experiences of the world. I conclude that more attention to descriptive research in psychophysics is warranted if what is sought is a philosophical theory of the nature of our perceptual relation with the world. (shrink)

Can young children such as 3-year-olds represent the world objectively? Some prominent developmental psychologists—such as Perner and Tomasello—assume so. I argue that this view is susceptible to a prima facie powerful objection: To represent objectively, one must be able to represent not only features of the entities represented but also features of objectification itself, which 3-year-olds cannot do yet. Drawing on Burge's work on perceptual constancy, I provide a response to this objection and motivate a distinction between three different kinds (...) of objectivity. This distinction helps advance current research on both objectivity and teleological action explanations in young children. (shrink)

Both philosophers of perception and analytic metaphysicians apply the tropes/universals distinction when considering the ontological status of visual properties. One way of arguing in favor of the trope interpretation of visual properties is to claim that the way in which we visually experience properties makes it plausible to characterize them as tropes. In this paper, I argue for a different position, namely that the way in which we visually experience properties provides a serious challenge for the trope interpretation, but not (...) for an interpretation in terms of universals. More specifically, I claim that the trope interpretations of visual properties have problems accounting for the fact that ordinary, veridical visual experiences can present the properties of two objects as strictly similar.

Significant variations in the way objects appear across different viewing conditions pose a challenge to the view that they have some true, determinate color. This view would seem to require that we break the symmetry between multiple appearances in favor of a single variant. A wide range of philosophical and non-philosophical writers have held that the symmetry can be broken by appealing to daylight viewing conditions—that the appearances of objects in daylight have a stronger, and perhaps unique, claim to reveal (...) their true colors. In this note we argue that, whatever else its merits, this appeal to daylight is not a satisfactory answer to the problem posed by perceptual variation. (shrink)

Phenomenal objectivism explains perceptual phenomenal character by reducing it to an awareness of mind-independent objects, properties, and relations. A challenge for this view is that there is a sense in which a distant tree looks smaller than a closer tree even when they are the same objective size (perceptual size variation). The dual content view is a popular objectivist account in which such experiences are explained by my objective spatial relation to the tree, in particular visual angle (perspectival size). I (...) describe a series of first-person experiments for investigating size experience. I use a ruler as a first-person method for operationalising perspectival size (Experiment 1). I use the corridor illusion (Experiment 2), outlining one’s head in the mirror (Experiment 3), and outlining the size of objects on glass (Experiment 4) to show a phenomenal difference in size for items in different depth contexts, despite being identical in visual angle. These finding demonstrate that visual angle cannot account for these spatial experiences. Psychological evidence provides further support for the thesis that subjects do not experience visual angle when depth information is present. Together this evidence supports the hypothesis that perceptual size variation cannot be accounted for by visual angle, hence undermining a plausible version of the dual content theory. This outcome, combined with problems raised by alternative objectivist accounts of size variation, provides support for a subjectivist account of size experience. (shrink)

Are there sensory states that, unlike mere sensory registrations, require an explanatory framework that goes beyond biology? Based on a reconstruction of Kant’s a priori, transcendental psychology, contemporary Kantians answer this question in the positive but dramatically limit the scope of psychology. In contrast, naturalistically oriented deflationists answer it in the negative, thereby not giving psychology any explanatory role whatsoever. In his recent monumental book Origins of Objectivity, Burge argues against both of these approaches and seeks to develop an intermediate (...) approach between them. This he does by embedding Kantian transcendental psychology in contemporary science of perception, thereby naturalizing the former and considerably broadening the scope of psychology. In this paper I critically examine Burge’s naturalized Kantianism, thereby defending transcendental Kantianism. To this end, I first outline Kantian transcendental psychology of perception, highlighting the features that distinguish it from biology. I then show how Burge naturalizes this psychology by embedding its most fundamental notions in contemporary science of perception. Based on all this, I conclude the paper by arguing for two closely related claims. First, that transformed into empirical psychology, Kantian transcendental psychology loses the features that distinguish it from biology. Second, that genuine perception starts at the high cognitive level for which transcendental psychology accounts and not at the rather low or elementary level on which Burge focuses. (shrink)

Attention seems to raise a problem for pure representationalism, the view that phenomenal content supervenes on representational content. The problem is that shifts of attention sometimes seem to bring about a change in phenomenal content without a change in representational content. I argue that the representationalist can meet this challenge, but that doing so requires a new view of the representational content of perception. On this new view, the representational content of perception is always relative to a way of attending. (...) I call this the attention-indexed view of perceptual content. (shrink)

Naturalist theories of representation have been attacked on the grounds of being too liberal on the minimal conditions for intentionality: they treat several states that are not representational as genuine representations. Behind this attack lies the problem of demarcation: what are the minimal conditions for intentionality that a state should satisfy to be genuinely representational? What are the limits of intentionality? This paper develops a dual proposal to solve this problem. First, I defend the explanatory role criterion in order to (...) assess proposals of minimal conditions for intentionality. I start by proposing the success pattern condition: a state represents a given external feature provided that there is a success pattern present in the behavioural output, and the system uses this state as a proxy for the presence of this external feature. However, this condition is not sufficient for minimal intentionality – there are both intentional and non-intentional success patterns. Another minimal condition is, hence, required to draw this distinction. I propose the constancy mechanism condition: a state is representational provided that the system employs a constancy mechanism in its production. The success pattern and constancy mechanism conditions jointly constitute the dual proposal for minimal intentionality. I argue that this proposal is explanatorily justified and, so, properly demarcates the limits of intentionality. (shrink)

How does perceptual experience disclose the world to our view? In the first introductory section, I set up a contrast between the representational and the purely relational conception of perceptual experience. In the second section, I discuss an argument given by Charles Travis against perceptual content. The third section is devoted to the phenomenon of perceptual constancy: in 3.1 I describe the phenomenon. In 3.2 I argue that the description given suggests a phenomenological distinction that can be deployed for a (...) defence of content. In 3.3 I compare and contrast my view of perceptual content with that of Susanna Schellenberg : 55–84, 2008). Finally, I support my conception of content by means of an argument that links content to the way in which the mind-independent nature of material objects is manifest in perceptual experience.

In “Perceptual Confidence,” I argue that our perceptual experiences assign degrees of confidence. In “Precision, not Confidence, Describes the Uncertainty of Perceptual Experience,” Rachel Denison disagrees. In this reply I first clarify what i mean by ‘perceptual experiences’, ‘assign’ and ‘confidence’. I then argue, contra Denison, that perception involves automatic categorization, and that there is an intrinsic difference between a blurry perception of a sharp image and a sharp perception of a blurry image. -/- .

How does perceptual experience disclose the world to us? According to the content view (CV), visual perceptual consciousness entails representational content. According to pure relationalism, perception is a non‐representational relation between a subject and an object. In this article, I argue that CV‐theorists are implicitly committed to the claim that there is an element of generality in perception, and I show how pure relationalists would emphasize the particularity of perception, instead of its generality. But I also argue that there are (...) good epistemological and phenomenological reasons for thinking that there is generality in perception. In particular, I focus on Brewer's purely relationalist account and I argue that it either fails to satisfy important phenomenological and epistemological requirements, or it introduces generality in a way that makes it collapse into CV. I contend that construing the debate between CV and pure relationalism in light of particularity and generality advances our understanding of how perceptual experience discloses the world to us, as well as strengthening the standing of CV.

A theoretical pillars of vision science in the information-processing tradition is that perception involves unconscious inference. The classic support for this claim is that, since retinal inputs underdetermine their distal causes, visual perception must be the conclusion of a process that starts with premises representing both the sensory input and previous knowledge about the visible world. Focus on this “argument from underdetermination” gives the impression that, if it fails, there is little reason to think that visual processing involves unconscious inference. (...) Here an alternative means of support for this pillar is proposed, based on another foundational challenge for the visual system: recognizing invariant properties of objects in the environment even though anything we encounter is never seen exactly the same way twice. Explaining how the visual system solves this invariance problem requires positing visual processes that exhibit many commonalities with inductive inference. Thus, this novel “argument from invariance” reveals one way in which visual processing clearly involves unconscious inference. (shrink)
