It is common to distinguish two great families of representation. Symbolic representations include logical and mathematical symbols, words, and complex linguistic expressions. Iconic representations include dials, diagrams, maps, pictures, 3-dimensional models, and depictive gestures. This essay describes and motivates a new way of distinguishing iconic from symbolic representation. It locates the difference not in the signs themselves, nor in the contents they express, but in the semantic rules by which signs are associated with contents. The two kinds of rule have (...) divergent forms, occupying opposite poles on a spectrum of naturalness. Symbolic rules are composed entirely of primitive juxtapositions of sign types with contents, while iconic rules determine contents entirely by uniform natural relations with sign types. This distinction is marked explicitly in the formal semantics of familiar sign systems, both for atomic first-order representations, like words, pixel colors, and dials, and for complex second-order representations, like sentences, diagrams, and pictures.

It is commonly assumed that images, whether in the world or in the head, do not have a privileged analysis into constituent parts. They are thought to lack the sort of syntactic structure necessary for representing complex contents and entering into sophisticated patterns of inference. I reject this assumption. “Image grammars” are models in computer vision that articulate systematic principles governing the form and content of images. These models are empirically credible and can be construed as literal grammars for images. (...) Images can have rich syntactic structure, though of a markedly different form than sentences in language. (shrink)

Many attempts to define depiction appeal to viewers' perceptual responses. Such accounts are liable to give a central role in determining depictive content to picture features responsible for the response, design. A different project is to give a compositional semantics for depictive content. Such attempts identify syntax: picture features systematically responsible for the content of the whole. Design and syntax are competitors. But syntax requires system, in how picture features contribute to content, that design does not. By examining John Kulvicki's (...) semantics for basic depictive content, I argue that the relevant systematicity is absent from the pictorial realm. (shrink)

A semantics of pictorial representation should provide an account of how pictorial signs are associated with the contents they express. Unlike the familiar semantics of spoken languages, this problem has a distinctively spatial cast for depiction. Pictures themselves are two-dimensional artifacts, and their contents take the form of pictorial spaces, perspectival arrangements of objects and properties in three dimensions. A basic challenge is to explain how pictures are associated with the particular pictorial spaces they express. Inspiration here comes from recent (...) proposals that analyze depiction in terms of geometrical projection. In this essay, I will argue that, for a central class of pictures, the projection-based theory of depiction provides the best explanation for how pictures express pictorial spaces, while rival perceptual and resemblance theories fall short. Since the composition of pictorial space is itself the basis for all other aspects of pictorial content, the proposal provides a natural foundation for further pictorial semantics. (shrink)

What is it for a picture to depict a scene? The most orthodox philosophical theory of pictorial representation holds that depiction is grounded in resemblance. A picture represents a scene in virtue of being similar to that scene in certain ways. This essay presents evidence against this claim: curvilinear perspective is one common style of depiction in which successful pictorial representation depends as much on a picture's systematic differences with the scene depicted as on the similarities; it cannot be analyzed (...) in terms of similarity alone. The same problem arises for many other kinds of depiction. The essay concludes that depiction in general is not grounded in resemblance but geometrical transformation. (shrink)

In this paper, I discuss the influential view that depiction, like language, depends on arbitrary conventions. I argue that this view, however it is elaborated, is false. Any adequate account of depiction must be consistent with the distinctive features of depiction. One such feature is depictive generativity. I argue that, to be consistent with depictive generativity, conventionalism must hold that depiction depends on conventions for the depiction of basic properties of a picture’s object. I then argue that two considerations jointly (...) preclude depiction from being governed by such conventions. Firstly, conventions must be salient to those who employ them. Secondly, those parts of pictures that depict basic properties of objects are not salient to the makers and interpreters of pictures. (shrink)

There are two distinct interpretations of the role that Feynman diagrams play in physics: (i) they are calculational devices, a type of notation designed to keep track of complicated mathematical expressions; and (ii) they are representational devices, a type of picture. I argue that Feynman diagrams not only have a calculational function but also represent: they are in some sense pictures. I defend my view through addressing two objections and in so doing I offer an account of representation that explains (...) why Feynman diagrams represent. The account that I advocate is a version of that defended by Kendall Walton, which provides us with a basic characterization of the way that representations in general work and is particularly useful for understanding distinctively pictorial representations - in Walton's terms, depictions. The question of the epistemic function of Feynman diagrams as pictorial representations is left for another time. (shrink)

This thesis attempts to describe and interpret the design practice of an American architect, Frank O. Gehry through concepts developed by French philosopher Gilles Deleuze and his collaborator, French psychotherapist, philosopher and activist, Félix Guattari. At the same time, prototyping a website-based interactive project called PLATEAU GEHRY_CONNECTIVES, it explores an alternative form for the Doctoral thesis. In addition to connections with visual arts, such as painting and cinema, the experimental project PLATEAU GEHRY_CONNECTIVES includes references to concepts and phenomena from various (...) areas of knowledge revealing distinctive, unusual qualities of Gehry’s creative approach in the production of design artefacts. The thesis documents and discusses means of representation in architectural design fused into the specific creative culture of Frank O. Gehry. It notices that the discourse in architectural theory and practice, often neglects what occurs on a particular molecular level of the architectural design process. It shows that elements of micro-level of design procedures render Gehry’s idiosyncratic design phenomena intelligible and perceptible in a new way. It claims that it has been possible because Deleuze and Guattari’s concepts become perceptibly operational in the interpretation of such phenomena, at the level of elementary units of Gehry’s design procedures. Moreover, through this close-up perspective, the thesis’ investigations identify certain similarities in the operational modes of the architect and the painter. It demonstrates how Gehry, who has anchored his interest in painting, and specifically in what he defined as ‘immediacy in painting,’ was able to transform the practice of architectural drawing from projective to a cognitive one. It also shows, how the architect re-defines the commonly applied projective geometries from passive, arbitrary role to an active agent, and how the architect links drawing practice with the construction process on a new, almost palpable level. While stressing its the manual character, the thesis demonstrates that Gehry’s explorative culture of challenging means of representation employed in architectural design production facilitates the re-disciplining of architecture culminating in the integration of the CATIA system in the design procedures. This study of Gehry’s design actions and strategies can help the reader to understand the significance of experimental and intuitive design practices. The thesis proposes the Deleuzian interpretation of Gehry’s experiments in the aesthetics of design thinking and acting. It renders perceptions of patterns, according to which, other design practices can operate. (shrink)

This introduction aims to familiarize readers with basic dimensions of variation among pictorial and diagrammatic representations, as we understand them, in order to serve as a backdrop to the articles in this volume. Instead of trying to canvas the vast range of representational kinds, we focus on a few important axes of difference, and a small handful of illustrative examples. We begin in Section 1 with background: the distinction between pictures and diagrams, the concept of systems of representation, and that (...) of the properties of usage associated with signs. In Section 2 we illustrate these ideas with a case study of diagrammatic representation: the evolution from Euler diagrams to Venn diagrams. Section 3 is correspondingly devoted to pictorial representation, illustrated by the comparison between parallel and linear perspective drawing. We conclude with open questions, and then briefly summarize the articles to follow. (shrink)

The representation of color by pictures raises worthwhile questions for philosophers and psychologists. Moreover, philosophers and psychologists interested in answering these questions will benefit by paying attention to each other's work. Failure to recognize the potential for interdisciplinary cooperation can be attributed to tacit acceptance of the resemblance theory of pictorial color. I argue that this theory is inadequate, so philosophers of art have work to do devising an alternative. At the same time, if the resemblance theory is false, then (...) color depiction has interesting implications for color science. Empirical researchers must rethink the widespread assumption that color recognition requires color constancy. I suggest that a neuropsychological account of color recognition will be instrumental to completing the philosophical task, but by the same token scientists might do well not to proceed without casting an eye to the work of philosophers of art.

Bullot & Reber (B&R) put forth a design stance to fuse psychological and art historical accounts of visual thinking into a single theory. We argue that this aspect of their proposal needs further fine-tuning. Issues of transgression and coherence are necessary to provide stability to the design stance. We advocate looking to Art Education for such fundamentals of picture understanding.

Meynell’s contention is that feminists should attend to pictures in science as distinctive bearers of epistemic content that cannot be reduced to propositions. Remarks on the practice and function of medical illustration—specifically, images Nancy Tuana used in her discussion of the construction of ignorance of women’s sexual function (2004)—show pictures to be complex and powerful epistemic devices. Their affinity with perennial feminist concerns, the relation between epistemic subject and object, and the nature of social knowledge, are of particular interest.

The spatial composition of human portraits obeys historically changing cultural norms. We show that it is also affected by cognitive factors that cause greater spontaneous attention to what is in front rather in the back of an agent. Scenes with more space in front of a directed object are both more often produced and judged as more aesthetically pleasant. This leads to the prediction that, in profile‐oriented human portraits, compositions with more space in front of depicted agents (a “forward bias”) (...) should be over‐represented. By analyzing a large dataset (total N of 1,831 paintings by 582 unique identified European painters from the 15th to the 20th century), we found evidence of this forward bias: Painters tended to put more free space in front of, rather than behind, the sitters. Additionally, we found evidence that this forward bias became stronger when cultural norms of spatial composition favoring centering became less stringent. (shrink)

In this article, we critically examine some of the ethical challenges and interpretive difficulties with possible future non-clinical applications of pediatric fMRI with a particular focus on applications in the classroom and the courtroom - two domains in which children come directly in contact with the state. We begin with a general overview of anticipated clinical and non-clinical applications of pediatric fMRI. This is followed by a detailed analysis of a range of ethical challenges and interpretive difficulties that trouble the (...) use of fMRI and are likely to be especially acute with non-clinical uses of the technology. We conclude that knowledge of these challenges and difficulties should influence policy decisions regarding the non-clinical uses of fMRI. Our aim is to encourage the development of future policies prescribing the responsible use of this neuroimaging technology as it develops both within and outside the clinical setting. (shrink)

Philosophers of information, according to Luciano Floridi (The philosophy of information. Oxford University Press, Oxford, 2010, p 32), study how information should be “adequately created, processed, managed, and used.” A small number of epistemologists have employed the concept of information as a cornerstone of their theoretical framework. How this concept can be used to make sense of seemingly intractable epistemological problems, however, has not been widely explored. This paper examines Fred Dretske’s information-based epistemology, in particular his response to radical epistemological (...) skepticism. We discuss the relationship between information, evidence and knowledge in relation to the problem of skepticism and the options available to an information-based epistemology for dealing with it.
