The problem of the richness of visual experience is that of finding principled grounds for claims about how much of the world a person actually sees at any given moment. It is argued that there are suggestive parallels between the two-component analysis of experience defended by Wilfrid Sellars, and certain recently advanced information processing accounts of visual perception. Sellars' later account of experience is examined in detail, and it is argued that there are good reasons in support of the claim that the sensory nonconceptual content of experience can vary independently of conceptual awareness. It is argued that the Sellarsian analysis is not undermined by recent work on change blindness and related phenomena; a model of visual experience developed by Ronald Rensink is shown to be in essential harmony with the framework provided by Sellars, and provides a satisfactory answer to the problem of the richness of visual experience.

The target article proposes that visual experience arises when sensorimotor contingencies are exploited in perception. This novel analysis of visual experience fares no better than the other proposals that the article rightly dismisses, and for the same reasons. Extracting invariants may be needed for recognition, but it is neither necessary nor sufficient for having a visual experience. While the idea that vision involves the active extraction of sensorimotor invariants has merit, it does not replace the need for perceptual representations. Vision is not just for the immediate controlling of action; it is also for finding out about the world, from which inferences may be drawn and beliefs changed.

Vision has been the primary focus of naturalistic philosophical research concerning perception and perceptual experience. Guided by visual experience and vision science, many philosophers have focused upon theoretical issues dealing with the perception of objects. Recently, however, hearing researchers have discussed auditory objects. I present the case for object perception in vision, and argue that an analog of object perception occurs in auditory perception. I propose a notion of an auditory object that is stronger than just that of an intentional object of audition, but that does not identify auditory objects with the ordinary material objects we see.

A fundamental assumption of Alexius Meinong's 1904 Theory of Objects is the act-content-object analysis of psychological experiences. I suggest that Meinong's theory need not be based on this analysis, but that an adverbial theory might suffice. I then defend the adverbial alternative against an objection raised by Roderick Chisholm, and conclude by presenting an apparently more serious objection based on a paradox discovered by Romane Clark.

This paper examines the status of unattended visual stimuli in the light of recent work on the role of attention in visual perception. Although the question of whether attention is required for visual experience seems very interesting, this paper argues that there currently is no good reason to take a stand on the issue. Moreover, it is argued that much of the allure of that question stems from a continued attachment to the defective ‘inner picture view’ of experience and a mistaken notion that the ultimate goal of vision is to produce visual experience. The paper considers a promising general account of the content and structure of vision and presents reasons for not taking that account to be committed to any substantive claims about the experiential status of unattended visual stimuli. Also addressed are the active nature of vision and the role of vision in enabling our ecological success. These considerations highlight that visual experience is not the whole of vision and that a much more important question about unattended visual stimuli than whether they are consciously experienced is what contribution they make to how we interact with the world.
