The modal object calculus is the system of logic which houses the (proper) axiomatic theory of abstract objects. The calculus has some rather interesting features in and of itself, independent of the proper theory. The most sophisticated, type-theoretic incarnation of the calculus can be used to analyze the intensional contexts of natural language and so constitutes an intensional logic. However, the simpler second-order version of the calculus couches a theory of fine-grained properties, relations and propositions and serves as a (...) framework for defining situations, possible worlds, stories, and fictional characters, among other things. In the present paper, we focus on the second-order calculus. The second-order modal object calculus is so-called to distinguish it from the second-order modal predicate calculus. Though the differences are slight, the extra expressive power of the object calculus significantly enhances its ability to resolve logical and philosophical concepts and problems. (shrink)

What makes an object the same persisting individual over time? Philosophers and psychologists have both grappled with this question, but from different perspectives—philosophers conceptually analyzing the criteria for object persistence, and psychologists exploring the mental mechanisms that lead us to experience the world in terms of persisting objects. It is striking that the same themes populate explorations of persistence in these two very different fields—e.g. the roles of spatiotemporal continuity, persistence through property change, and cohesion violations. Such similarities (...) may reflect an underlying connection, in that psychological mechanisms of object persistence (especially relevant parts of mid-level visual object processing) may serve to underlie the intuitions about persistence that fuel metaphysical theories. This would be a way for cognitive science to join these two disparate fields, helping to explain the possible origins and reliability of some metaphysical intuitions, and perhaps leading to philosophical progress.

What is implicit in a typically human perception of a material object? First, perceivability is a contingent property of its bearer, relative to perceiver and conditions. Typically, human perception is special in involving the use of concepts and an awareness of object‐structures. When we visually recognize a material object, an almost limitless array of properties and procedures are by implication condensed into an instant: one entertains multiple beliefs, and posits at a distance, multiple properties. Then the experiential (...) integration of the almost limitless visual evidence of a material object is dubbed ‘constituting the material object out of experience’. Central concepts in doing so are those of side, outside, surface, interior, and part. The most important of these experiential syntheses is the spatial, whose unit is the 3D‐seeing of object‐sides, a concept that depends upon those of 2D/3D and 2D/2D seeing. Two vitally important elements in this procedure are, first, the work of the understanding, second, an awareness of the objective physical situation of perceiver and object. (shrink)

Imagine a world without things. There would be nothing to describe, nothing to explain, remark, interpret, or complain about. Without things, we would stop speaking; we would become as mute as things are alleged to be. In nine original essays, internationally renowned historians of art and of science seek to understand how objects become charged with significance without losing their gritty materiality. True to the particularity of things, each of the essays singles out one object for close attention: a (...) Bosch drawing, the freestanding column, a Prussian island, soap bubbles, early photographs, glass flowers, Rorschach blots, newspaper clippings, paintings by Jackson Pollock. Each is revealed to be a node around which meanings accrete thickly. But not just any meanings: what these things are made of and how they are made shape what they can mean. Neither the pure texts of semiotics nor the brute objects of positivism, these things are saturated with cultural significance. Things become talkative when they fuse matter and meaning; they lapse into speechlessness when their matter and meanings no longer mesh. Each of the nine objects examined in this book had its historical moment, when the match of this thing to that thought seemed irresistible. At these junctures, certain things become objects of fascination, association, and endless consideration; they begin to talk. Things that talk fleetingly realize the dream of a perfect language, in which words and world merge.Essays Lorraine Daston, Peter Galison, Anke te Heesen, Caroline A.

Bildung, a German pedagogical term with the sense of ‘educating oneself’, refers to some of the most complex human activities. It is constitutive for human existence, because it is related to the characteristic of meaning. Because of the great relevance of Bildung for people, education is essential for furthering it. The two purposes of this contribution are: i. to examine the structure of one main process component of Bildung, namely the process of designing an image (Bild) of the changes to (...) be furthered in the educand, and ii. to explain this process component of Bildung. This process is theoretically structured as a subject‐object transformation, and the attempt is made to explain this from an idealistic perspective. Building upon this foundation, the article shows how the process of designing an image for Bildung can be furthered educationally. (shrink)

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)

Object files (OFs) are hypothesized mid-level representations which mediate our conscious perception of persisting objects—e.g. telling us ‘which went where’. Despite the appeal of the OF framework, not previous research has directly explored whether OFs do indeed correspond to conscious percepts. Here we present at least one case wherein conscious percepts of ‘which went where’ in dynamic ambiguous displays diverge from the analogous correspondence computed by the OF system. Observers viewed a ‘bouncing/streaming’ display in which two identical objects moved (...) such that they could have either bounced off or streamed past each other. We measured two dependent variables: (1) an explicit report of perceived bouncing or streaming; and (2) an implicit ‘object-specific preview benefit’ (OSPB), wherein a ‘preview’ of information on a specific object speeds the recognition of that information at a later point when it appears again on the same object (compared to when it reappears on a different object), beyond display-wide priming. When the displays were manipulated such that observers had a strong bias to perceive streaming (on over 95% of the trials), there was nevertheless a strong OSPB in the opposite direction—such that the object files appeared to have ‘bounced’ even though the percept ‘streamed’. Given that OSPBs have been taken as a hallmark of the operation of object files, the five experiments reported here suggest that in at least some specialized (and perhaps ecologically invalid) cases, conscious percepts of ‘which went where’ in dynamic ambiguous displays can diverge from the mapping computed by the object-file system.

A new method was devised to test object permanence in young infants. Fivemonth-old infants were habituated to a screen that moved back and forth through a 180-degree arc, in the manner of a drawbridge. After infants reached habituation, a box was centered behind the screen. Infants were shown two test events: a possible event and an impossible event. In the possible event, the screen stopped when it reached the occluded box; in the impossible event, the screen moved through the (...) space occupied by the box. The results indicated that infants looked reliably longer at the impossible than at the possible event. This hnding suggested that infants (1) understood that the box continued to exist, in its same location, after it was occluded by the screen, and (2) expected the screen to stop against the occluded box and were surprised, or puzzled, when it failed to do so. A control experiment in which the box was placed next to the screen provided support for this interpretation of the results. Together, the results of these experiments indicate that, contrary to Piaget’s (1954) claims, infants as young as 5 months of age understand that objects continue to exist when occluded. The results, also indicate that 5-month-old infants realize that solid objects do not move through the space occupied by other solid objects. (shrink)

Object-Oriented Ontology (OOO) is a contemporary form of realism concerned with the investigation of “objects” broadly construed. It may be characterised in terms of a metaphysical pluralism to the extent that it recognises infinitely many different kinds of emergent entities, and this fact in turn leads to a number of questions concerning the nature of objects and emergence in OOO: what is the precise meaning of an emergent entity in OOO? How has emergence been denied throughout the history of (...) Western thought? Is there a specific object-oriented account of emergence? What is the causal mechanism which provides the conditions of possibility for the generation of emergent entities? In this article, I aim to answer all these questions by constructing the first extensive account of real emergence in the context of Object-Oriented Ontology, and I also seek to tie this analysis to the notion of “vicarious” or indirect causation.

This article argues that bodily awareness is a basic form of self-consciousness through which perceiving agents are directly conscious of the bodily self. It clarifies the nature of bodily awareness, categorises the different types of body-relative information, and rejects the claim that we can have a sense of ownership of our own bodies. It explores how bodily awareness functions as a form of self-consciousness and highlights the importance of certain forms of bodily awareness that share an important epistemological property with (...) canonical forms of self-consciousness such as introspection.

What is a thing? What is an object? Tristan Garcia decisively overturns 100 years of Heideggerian orthodoxy about the supposedly derivative nature of objects to put forward a new theory of ontology that gives us deep insights into the world and our place in it."e.

We investigated whether a pre-change representation is inhibited or weakened under correct change detection. Two arrays of six objects were rapidly presented for change detection in three experiments. After detection, the perceptual identification of degraded stimuli was tested in Experiments 1 and 2. The weakening of a pre-change representation was not observed under correct detection. The repetition priming effect was observed for a pre-change object and the magnitude was equivalent to the effect for a post-change object. Under change (...) blindness, repetition priming for a pre-change representation was observed when detection did not require report of location in Experiment 1 and was not observed when location was required to be reported in Experiment 2. The results of Experiment 3 showed that a pre-change representation was recognized at a higher rate under correct detection than under change blindness, reflecting a stronger rather than a weaker pre-change representation in the former context.

Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of hallucination (...) and argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.
