A number of philosophers are committed to the view that sense experiences, in so far as they have contents, have propositional contents, but this is more often tacitly accepted than argued for in the literature. This paper explains the propositional account and presents a basic case in support of it in a simple and straightforward way which does not involve commitment to any specific philosophical theory of perception.

It is clear that visual imagery is somehow significantly visual. Some theorists, like Kosslyn, claim that the visual nature of visualisations derives from features of the neural processes which underlie those episodes. Pylyshyn claims, however, that it may merely reflect special features of the contents which we grasp when we visualise things. This paper discusses and rejects Pylyshyn's own attempts to identify the respects in which the contents of visualisations are notably visual. It then offers a novel and very different account of what is distinctively sensory about the contents of sensory images. The paper's alternative account is used in explaining various pieces of phenomenological and behavioural data concerning visualisation. Finally, it is tentatively suggested that the proposed account of the contents of sensory images may also shed light upon some of the neurological data involving visualisation and sensory imagery more generally.

In this paper I address an important question concerning the nature of visual content: are the contents of human visual states and experiences exhaustively fixed or determined (in the non-causal sense) by our intrinsic physical properties? The individualist answers this question affirmatively. I will argue that such an answer is mistaken. A common anti-individualist or externalist tactic is to attempt to construct a twin scenario involving humanoid duplicates who are embedded in environments that diverge in such a way that it appears to be necessary to attribute divergent contents to their respective visual states. In the first half of the paper I discuss some of the twin scenarios that are prominent in the literature and argue that they fail to undermine individualism. Indeed I argue that due to important facts about our internal workings, a convincing externalist twin scenario involving humanoid protagonists cannot be constructed. However, I argue that such a result does not conclusively establish an individualist thesis and that in order to settle the question at issue it is necessary to construct an independently motivated theory of visual content. I attempt to do this in the second half of the paper by developing a theory at the core of which is the idea that the contents of our visual states and experiences are determined by the causal powers vis-.

Certain simple thoughts about pictures suggest that the contents of pictures are closely bound to vision. But how far can the striking features of depiction be accounted for merely in terms of the especially visual contents which belong to pictures, without considering, for example, any issues concerning the nature of the visual experiences with which pictures provide us? This article addresses that question by providing an account of the distinctively visual contents belonging to pictures, and by using that account to explain many notable general facts about depiction. Some implications of the resulting framework for the main stream of current theorizing about pictorial representation are also discussed.

I address three interrelated issues concerning the contents of experiences. First, I address the preliminary issue of what it means to say that experiences have contents. Then I address the issue of why we should believe that experiences have contents. Finally, I address the issue of what the contents of experiences are.

I offer a formulation of the claim that experiences have contents.I also suggest a new method for determining what the contents of our experiences are, which can be applied to the issue of whether high-level properties such as being a tomato enter into the content of experience.

In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of ...

In this paper I discuss several proposals for how to find out which contents visual experiences have, and I defend the method I.

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.
