Conceptual atomists argue that most of our concepts are primitive. I take up three arguments that have been thought to support atomism and show that they are inconclusive. The evidence that allegedly backs atomism is equally compatible with a localist position on which concepts are structured representations with complex semantic content. I lay out such a localist position and argue that the appropriate position for a non-atomist to adopt is a pluralist view of conceptual structure. I show several ways in (...) which conceptual pluralism provides an advantage in satisfying the empirical and philosophical demands on a theory of conceptual structure and content. (shrink)

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. (...) A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities. (shrink)

Theories of emotions traditionally divide into two categories. According to some researchers, emotions are or essentially involve evaluative thoughts or judgments. These are called cognitive theories. According to other researchers, an emotion can occur without any thought. These are called non-cognitive theories. Some defenders of non-cognitive theories argue that emotions are action tendencies, others say they are feelings, and still others say they are affect programs, which encompass a range of internal and external events. One of the most celebrated non-cognitive (...) theories owes, independently, to William James and Carl Lange. According to them, emotions are perceptions of patterned changes in the body. I think the perceptual theory of emotions is basically correct, but it needs to be updated. In this discussion, I will offer a summary and defence.The question I am addressing bears on the question of modularity. Within cognitive science, there is a widespread view that perceptual systems are modular. (shrink)

Philosophers and cognitive scientists have worried that research on animal mind-reading faces a ‘logical problem’: the difficulty of experimentally determining whether animals represent mental states (e.g. seeing) or merely the observable evidence (e.g. line-of-gaze) for those mental states. The most impressive attempt to confront this problem has been mounted recently by Robert Lurz. However, Lurz' approach faces its own logical problem, revealing this challenge to be a special case of the more general problem of distal content. Moreover, participants in this (...) debate do not agree on criteria for representation. As such, future debate should either abandon the representational idiom or confront underlying semantic disagreements. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

The idea that only complex brains can possess genuine representations is an important element in mainstream philosophical thinking. An alternative view, which I label ‘liberal representationalism’, holds that we should accept the existence of many more full-blown representations, from activity in retinal ganglion cells to the neural states produced by innate releasing mechanisms in cognitively unsophisticated organisms. A promising way of supporting liberal representationalism is to show it to be a consequence of our best naturalistic theories of representation. However, several (...) philosophers and scientists have recently argued against this strategy. In the paper I counter these objections in defense of liberal representationalism. (shrink)

Intentionality is a central feature of our understanding of the world. We daily attribute intentional states (like beliefs, desires or perceptual states) to explain the behavior of other agents, and many theories appeal to them to understand more complex notions. Nonetheless, intentional states are puzzling entities. This article explains what intentionality is and why it is so important and problematic at the same time. Secondly, it examines various naturalistic theories, which seek to show that intentionality is compatible with a scientific (...) worldview. Finally, given that all extant proposals face significant difficulties, it explores the available options in case no naturalistic theory can succeed. (shrink)

The indeterminacy problem is one of the most prominent objections against naturalistic theories of content. In this essay I present this difficulty and argue that extant accounts are unable to solve it. Then, I develop a particular version of teleosemantics, which I call ’explanation-based teleosemantics’, and show how this outstanding problem can be addressed within the framework of a powerful naturalistic theory.

[1] We all know that language is vague. The majority of our terms admit borderline cases. We are notoriously unable to resolve the precise number grains required for a portion of sand to fall under the predicate "heap". It might be supposed that blurry boundaries are, at bottom, an ontological phenomenon. Perhaps the indeterminacy of our predicates is inherited from the indeterminacy of the properties they denote. Perhaps objects can also by vague, rendering singularly terms, including proper names, uncomfortably imprecise. (...) This thesis has been dismissed, challenged, and championed by various philosophers over the course of the century. Undoubtedly the most widely discussed objection to vague ontology comes in the form of a one-page argument devised by Gareth Evans (1978). Although other arguments against vague objects have been proposed,1 Evans' argument has occupied center stage, clarifying and provoking debate. Its impact reconfirms the value of Evans' philosophical legacy. (shrink)

This paper examines the pressures leading two very different Early Modern philosophers, Descartes and Locke, to invoke two ways in which thought is directed at objects. According to both philosophers, I argue, the same idea can simultaneously count as “of” two different objects—in two different senses of the phrase ‘idea of’. One kind of intentional directedness is invoked in answering the question What is it to think that thus-and-so? The other kind is invoked in answering the question What accounts for (...) the success of our proper methods of inquiry? For Descartes as well as Locke, the two kinds of “ofness” come apart as a result of strong rationalist commitments. However, I will suggest that even if we reject such commitments, we go wrong if we assume that a single kind of intentional directedness suffices to address both questions. (shrink)

There seems to be a large gulf between percepts and concepts. In particular, con- cepts seem to be capable of representing things that percepts cannot. We can conceive of things that would be impossible to perceive. (The converse may also seem true, but I will leave that to one side.) In one respect, this is trivially right. We can conceive of things that we cannot encounter, such as unicorns. We cannot literally perceive unicorns, even if we occasionally.

This paper outlines Jesse Prinz’s theory that emotions represent values by registering bodily changes, discusses two objections, and concludes that Prinz’s theory stands in need of modification: while emotions do represent values, they do not do so in the first place by registering bodily changes, but by processing information about how things we care about fare in the world. The function of bodily changes is primarily to motivate and prepare us for action.
