The notion of an object file figures prominently in recent work in philosophy and cognitive science. Object files play a role in theories of singular reference, object individuation, perceptual memory, and the development of cognitive capacities. However, the philosophical literature lacks a detailed, empirically informed theory of object files. In this paper, we articulate and defend the multiple-slots view, which specifies both the format and architecture of object files. We argue that object files represent in a non-iconic, propositional format that (...) incorporates discrete symbols for separate features. Moreover, we argue that features of separate categories are stored in separate memory slots within an object file. We supplement this view with a computational framework that characterizes how information about objects is stored and retrieved. (shrink)

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

Objects are central in visual, auditory, and tactual perception. But what counts as a perceptual object? I address this question via a structural unity schema, which specifies how a collection of parts must be arranged to compose an object for perception. On the theory I propose, perceptual objects are composed of parts that participate in causally sustained regularities. I argue that this theory falls out of a compelling account of the function of object perception, and illustrate its applications to multisensory (...) perception. I also argue that the account avoids problems faced by standard views of visual and auditory objects. (shrink)

Many of the objects that we perceive have an important characteristic: When they move, they change shape. For instance, when you watch a person walk across a room, her body constantly deforms. I suggest that we exercise a type of perceptual constancy in response to changes of this sort, which I call structure constancy. In this paper I offer an account of structure constancy. I introduce the notion of compositional structure, and propose that structure constancy involves perceptually representing an object (...) as retaining its compositional structure over time. I argue that compositional structure is represented in visual phenomenology, and I also assemble empirical evidence in support of the claim that compositional structure is recovered by the visual system. Finally, I draw out consequences of this account. I argue that structure constancy has implications for the predictive capacities of perception, and that the phenomenon places important constraints on viable accounts of both the format and reference frame of visual experience.

Some philosophers have suggested that certain shifts in perceptual organization are counterexamples to representationalism about phenomenal character. Representationalism about phenomenal character is, roughly, the view that there can be no difference in the phenomenal character of experience without a difference in the representational content of experience. In this paper, I examine three of these alleged counterexamples: the dot array (Peacocke 1983), the intersecting lines (Speaks 2010), and the 3 X 3 grid (Nickel 2007). I identify the two features of their (...) phenomenology that call for explanation: grouping and prominence. I then argue that representationalists can adequately account for both of these features. I also critique some previous treatments of grouping and prominence. (shrink)

Many have held that when a person visually attends to an object, her visual system deploys a representation that designates the object. Call the referential link between such representations and the objects they designate attentive visual reference. In this article I offer an account of attentive visual reference. I argue that the object representations deployed in visual attention—which I call attentive visual object representations —refer directly, and are akin to indexicals. Then I turn to the issue of how the reference (...) of an AVOR is determined relative to a context. After raising problems for existing accounts, I propose a mechanism of reference determination that is both causal and descriptive: For an AVOR to refer to a particular object, the object must appropriately cause the deployment of the AVOR, and the AVOR must be associated with descriptive information about some of the object's geometrical and mereological properties.

This essay explores how economic theory and historical inquiry were brought together for one of the first times in modern political thought in Books II and III of Adam Smith's Wealth of Nations. It shows how the theory of capital found in Book II provides a perspective for thinking about historical development and political institutions that is in sharp contrast with the historical record traced out in Book III. Smith's solution to the problem of reconciling economic theory and history lies (...) in a complex understanding of the nature of rational economic behaviour and how it has been affected by uncertainty and institutional development in human history. Embedded in Smith's political economy is not only a new theory of economic life, but a new political understanding of the importance of history to contemporary political life. (shrink)

What kinds of things can we be morally responsible for? Andrew Khoury offers an answer that includes (i) an argument for the impossibility of blameworthiness for overt action, and (ii) the assertion that “willings are the proper object of responsibility in the context of action”. After presenting an argument for the inconsistency of Khoury’s answer to our focal question, I defend the following partial answer that resembles, but differs importantly from, Khoury’s answer: one can be blameworthy for a practical decision—that (...) is, an essentially intentional momentary mental action of forming an intention to do something that resolves prior felt unsettledness about what to do.

Here are two prima facie plausible theses about propositional knowledge: a belief could still constitute knowledge even if the belief is justified in a way that’s compatible with its being either false or accidentally true; each instance of knowledge is related to its subject in a way similar to that in which each intentional action is related to its agent. Baron Reed develops and defends a novel argument for the incompatibility of and. In this paper, I clarify and critically assess (...) Reed’s incompatibility argument. Against the backdrop of an example in which an action is non-intentional due to the role that an accidentally true belief plays in the action’s etiology, I argue that Reed’s incompatibility argument defeats itself: two of its premises are themselves jointly incompatible.

This paper analyses Quentin Meillassoux’s criticism of Kantian philosophy. The objective of the paper is to delineate the connection Meillassoux asserts between the problem of induction and Kant’s account of finitude. After examining Meillassoux’s elucidations on the connection between the two, I argue that Meillassoux’s characterization of Kantian philosophy as ‘weak correlationism’ is not only inaccurate but also undermines the novelty of Kantian philosophy, especially Kant’s (critical) response to the problem of induction. The paper concludes with the claim that Meillassoux’s (...) criticism of modern philosophy, especially Kantian critical philosophy, does not convince us to abandon the problem of finitude but points to the need for a more accurate understanding of finitude.
