This article aims at defending the old theory of iconological dualism that opposes ‘handmade’ pictures to photographic pictures. I defend a new version of that theory, according to which photographs always enable viewers to have singular thoughts on the things photographed, while handmade pictures by themselves never enable viewers to have singular thoughts but only enable them to have what I call ‘thoughts by depiction’. To this end, I defend the old theory according to which singular thoughts require a special (...) relation—called ‘acquaintance’—between the thinker and the object thought about. I put this traditional view forward thanks to a new version of the classic spy argument for the acquaintance constraint on singular thoughts. (shrink)

The similarity view of scientific representation has recently been subjected to strong criticism. Much of this criticism has been directed against a ?naive? similarity account, which tries to explain representation solely in terms of similarity between scientific models and the world. This article examines the more sophisticated account offered by the similarity view's leading proponent, Ronald Giere. In contrast to the naive account, Giere's account appeals to the role played by the scientists using a scientific model. A similar move is (...) often made by defenders of resemblance theories of depiction, who invoke the role played by the artist, or by the viewers of a painting. In this article I look to debates over depiction to assess the difficulties facing those who wish to defend the similarity view of scientific representation. I then turn to examine Giere's account. Ultimately, I argue, this account is unsuccessful: while appealing to the role of scientists offers a promising way to defend the similarity view, Giere's own account does not capture what it is that scientists do when they use a model to represent the world.

Philosophical discussions of depiction sometimes suffer from a lack of differentiation between several questions concerning the nature of pictorial representation. To provide a suitable framework I distinguish six such questions and several levels on which one might want to proceed in order to answer some of them. With this background, I reconstruct Goodman's and Elgin's answer to the specific question: What distinguishes the pictorial from the verbal or linguistic? I try to reveal some major motivations behind their system-oriented approach and (...) to indicate some reasons why a strategy of this kind is to a certain extent mandatory to grasp the nature of the pictorial. The system-relative and functional character of depiction has to be captured by every adequate theory. (shrink)
