This paper argues against definitions of depiction in terms of the syntactic and semantic properties of symbol systems. In particular, it is argued that John Kulvicki's definition of depictive symbol systems in terms of relative repleteness, semantic richness, syntactic sensitivity and transparency is susceptible to similar counterexamples as Nelson Goodman's in terms of syntactic density, semantic density and relative repleteness. The general moral drawn is that defining depiction requires attention not merely to descriptive questions about syntax and semantics, but also (...) to foundational questions about what makes it the case that depictions have the syntactic and semantic properties they do.

By defining both depictive and linguistic representation as kinds of symbol system, Nelson Goodman attempts to undermine the platitude that, whereas linguistic representation is mediated by convention, depiction is mediated by resemblance. I argue that Goodman is right to draw a strong analogy between the two kinds of representation, but wrong to draw the counterintuitive conclusion that depiction is not mediated by resemblance.

The traditional puzzles about belief reports puzzles rest on a certain seemingly innocuous assumption, that 'that'-clauses specify belief contents. The main theories of belief reports also rest on this "Specification Assumption", that for a belief report of the form 'A believes that p' to be true,' the proposition that p must be among the things A believes. I use Kripke's Paderewski case to call the Specification Assumption into question. Giving up that assumption offers prospects for an intuitively more plausible approach (...) to the semantics of belief reports. But this approach must confront a puzzle of its own: it turns out that every case is a Paderewski case, at least potentially. (shrink)

Analog representation is often cast in terms of an engineering distinction between smooth and discrete systems. The engineering notion cuts across interesting representational categories, however, so it is poorly suited to thinking about kinds of representation. This paper suggests that analog representations support a pattern of interaction, specifically open-ended searches for content across levels of abstraction. They support the pattern by sharing a structure with what they represent. Continuous systems that satisfy the engineering notion are exemplars of this kind because (...) they are uninterpretable unless they are structure-preserving. Analog representations, so understood, include pictures, images, diagrams, and most graphs. This conception of analogicity also fits well with a line of thought about what makes perceptual states distinctive: they satisfy a “parts principle”. (shrink)

Every materially adequate explication of the concepts ``picture''and ``the pictorial'' has to appeal to syntactical properties.From the available definitions, a conception of syntax is extractedthat is applicable to symbol systems of any sort. Against thisbackground, it is shown that a non-semantical characterization ofthe pictorial is mandatory. Finally, specific syntactical featuresare explicated that recommend themselves as necessary conditions forthe application of the concept of a picture.

How do people make deductions? The orthodox view in psychology is that they use formal rules of inference like those of a “natural deduction” system.Deductionargues that their logical competence depends, not on formal rules, but on mental models. They construct models of the situation described by the premises, using their linguistic knowledge and their general knowledge. They try to formulate a conclusion based on these models that maintains semantic information, that expresses it parsimoniously, and that makes explicit something not directly (...) stated by any premise. They then test the validity of the conclusion by searching for alternative models that might refute the conclusion. The theory also resolves long-standing puzzles about reasoning, including how nonmonotonic reasoning occurs in daily life. The book reports experiments on all the main domains of deduction, including inferences based on prepositional connectives such as “if” and “or,” inferences based on relations such as “in the same place as,” inferences based on quantifiers such as “none,” “any,” and “only,” and metalogical inferences based on assertions about the true and the false. Where the two theories make opposite predictions, the results confirm the model theory and run counter to the formal rule theories. Without exception, all of the experiments corroborate the two main predictions of the model theory: inferences requiring only one model are easier than those requiring multiple models, and erroneous conclusions are usually the result of constructing only one of the possible models of the premises.

Typical accounts of imagistic content have focused on the apparent analog character or continuous variability of images. In contrast, I consider the distinctive features of digital images, those composed of finite sets of discrete pixels. A rich source of evidence on digital imagistic content is found in the content-preserving algorithms that resize and reproduce digital images on computer screens and printers. I argue that these algorithms reveal a distinctive structural feature: digital images are always compositional (their parts contribute systematically to (...) overall content), but never inverse compositional (atomic parts may be replaced nonsynonymously without changing content). This indicates a sharp contrast with linguistic representations, which may or may not be compositional, and may or may not be inverse compositional. I argue this result sheds new light on the claim that imagistic content is inherently perspectival. (shrink)

This article focuses on the difficulty for a general theory of depiction of providing a notion of pictorial content that accommodates the full diversity of picture types. The article begins by introducing two basic models of pictorial content using paradigmatic positions that maximize the ability of the respective models to deal with pictorial diversity. Kulvicki's On Images is interpreted as a generalized projection-based model which proposes a scene-centred notion of pictorial content. By contrast, Lopes's aspect-recognition theory, in Understanding Pictures, is (...) taken to exemplify a recognition-based model of pictorial content. It is then considered how applicable these two notions of pictorial content are to a spectrum of different picture types, highlighting differences between mechanically produced and “freehand” pictures. It is shown that while the projection-based and recognition-based models are each required for some picture types, neither model can be applied over the whole spectrum of diverse picture types. This, it is argued, has the far-reaching consequence that neither the projection model nor the recognition model, nor any unitary combination of the two, can provide the basis for a theory of depiction applying to all pictures.

Nelson Goodman’s theory of symbol systems expounded in his Languages of Art has been frequently criticized on many counts. Yet it exerts a strong influence and is treated as one of the major twentieth-century theories on the subject.While many of Goodman’s controversial theses are criticized, the technical notions he used to formulate them seem to have been treated as neutral tools. One such technical notion is that of the density of symbol systems. This serves to distinguish linguistic symbols from pictorial (...) representations and is a crucial part of Goodman’s explanation of what constitutes aesthetic experience. Thus its significance for Goodman’s theory is fundamental.The aim of this paper is a detailed, logical analysis of this notion. It turns out that Goodman’s definition is highly problematic and cannot be applied to symbol systems in the way Goodman envisaged. To conclude, Goodman’s theory is problematic not just because of its controversial theses but also because of logical problems with the technical notions used at its very core. Hence the controversial claims are not simply contestable, but inaccurately expressed. (shrink)
