Little has been said about whether pictures can depict properties of properties. This article argues that they do. As a result, resemblance theories of depiction must be changed to accommodate this phenomenon. In addition, diagrams and maps are standardly understood to represent properties of properties, so this article brings accounts of depiction closer to accounts of diagrams than they had been before. Finally, the article suggests that recent work on perceptual content gives us reason to believe we can perceive properties of properties.

Over the last fifteen years, communication has become pictorial in a manner that it never was before. Billions of people have smart phones that enable them to take, edit, and share pictures easily whenever they choose to do so. This has created expressive niches within which new activities, with their own norms, continue to develop. Ready availability of these pictorial modes of communication, we claim, not only constitutes a change in the range of our communicative practices, but also changes the world about which we communicate. Increasingly, we are making a world that’s worth depicting, using the tools we now possess. This paper will unpack one example of this phenomenon, trompe l’oeil street art. More and more of this seems to be produced with the intention that it is seen primarily in pictures. It makes sense that anything someone makes, and wants to be seen, would be made with decent photography potential in mind. You want photos to be able to, as they say, do justice to your work no matter what kind of visual work you make. In these cases, however, the pictures of the work are reliably more interesting than the pieces seen in the flesh.

The central claim of this paper is that what it is like to see green or any other perceptible property is just the perceptual mode of presentation of that property. Perceptual modes of presentation are important because they help resolve a tension in current work on consciousness. Philosophers are pulled by three mutually inconsistent theses: representational externalism, representationalism, and phenomenal internalism. I throw my hat in with defenders of the first two: the externalist representationalists. We are faced with the problem of explaining away intuitions that favor phenomenal internalism. Perceptual modes of presentation account for what it is like to see properties in a way that accommodates those intuitions without vindicating phenomenal internalism itself. Perceptual MoPs therefore provide a new way of being an externalist representationalist

Long-exposure photographs present distinctive philosophical challenges. They do not quite look like things in motion. Experiences of such photos take time, but not in a way that mimics the time of the motion depicted. In fact, it would not be off base to worry that these photos fail, strictly speaking, to depict motion or things-in-time. And if they fail to depict motion, then it is an interesting question what, if anything, they succeed in depicting. These timeless traces of temporal patterns are thus a challenge to how we understand pictures. In addition to being representations, however, such photographs are recordings. They witlessly register aspects of scenes in a manner that can be replayed. The following shows that recording is a valuable and neglected tool for investigating representational practices. Aspects of what photos record also figure in their representational contents, and this provides a way of approaching the photography of events in time. This article proceeds by framing, and then answering, three questions. First, what do photos record about temporal patterns? Second, which aspects of such recordings also show up in photos’ representational contents? And third, do these pictures depict, rather than merely represent, such temporal patterns?

Problems concerning scientists’ uses of representations have received quite a bit of attention recently. The focus has been on how such representations get their contents and on just what those contents are. Less attention has been paid to what makes certain kinds of scientific representations different from one another and thus well suited to this or that epistemic end. This article considers the latter question with particular focus on the distinction between images and graphs on the one hand and descriptions and related representations on the other. *Received January 2008; revised September 2009. †To contact the author, please write to: Department of Philosophy, Dartmouth College, Hanover, NH 03755; e‐mail: [email protected].
