Reidentification scepticism is the view that we cannot knowledgeably reidentify previously perceived objects. Amongst classical Indian philosophers, the Buddhists argued for reidentification scepticism. In this essay, I will discuss two responses to this Buddhist argument. The first response, defended by Vācaspati Miśra (9th century CE), is that our outer senses allow us to knowledgeably reidentify objects. I will claim that this proposal is problematic. The second response, due to Jayanta Bhaṭṭa (9th century CE), is that the manas or (...) the inner sense, functioning as a capacity of attention, helps us knowledgeably reidentify objects. I will explain how this second response answers the Buddhists’ challenge. (shrink)

A certain dilemma is inherent in relational accounts of space and time. If any objects endure through change, then temporal elements other than relations are required to describe them. If, on the other hand, no objects endure through change, no permanent reference system is available in terms of which to define the "same place" at different times. An argument which, by exploiting this latter difficulty, attempts to show that "objects with some endurance through time" must be accepted as fundamental is (...) examined and found inconclusive. A sketch is then given of an alternative scheme which does allow the relevant spatial comparisons, but which does not countenance the reidentification of particulars. The discussion is intended to show that the relationist can, as indeed he must, deny the second horn of this delemma. (shrink)

Millikan's account of substance concepts fails to do away with features. Her approach simply moves the suite of relevant features into an encapsulated module. The crux of the problem for scientists studying human infants and nonhuman animals is to determine how individuals reidentify objects and events in the world.

Conceptualist accounts of the representational content of perceptual experiences have it that a subject _S_ can experience no object, property, relation, etc., unless _S_ "i# possesses and "ii# exercises concepts for such object, property, or relation. Perceptual experiences, on such a view, represent the world in a way that is conceptual.

The quantum symmetrization procedure that is used to handle systems of identical quantum particles brings into question whether the elementary constituents of matter, such as electrons, have the fundamental characteristics of persistence and reidentifiability that are attributed to classical particles. However, we presently lack a coherent conception of matter composed of entities that do not possess one or both of these fundamental characteristics. We also lack a clear a priori understanding of why systems of identical particles (as opposed to non-identical (...) particles) require special mathematical treatment, and this only in the quantum mechanical (as opposed to classical mechanical) setting. -/- Here, on the basis of a conceptual analysis of a recent mathematical reconstruction of the quantum symmetrization procedure, we argue that the need for the symmetrization procedure originates in the confluence of identicality and the active nature of the quantum measurement process. We propose a conception in which detection-events are ontologically primary, while the notion of individually persistent object is relegated to merely one way of bringing order to these events. On this basis, we outline a new interpretation of the symmetrization procedure which gives a new physical interpretation to the indices in symmetrized states and to non-symmetric measurement operators.

Person reidentification aims to recognize a specific pedestrian from uncrossed surveillance camera views. Most re-id methods perform the retrieval task by comparing the similarity of pedestrian features extracted from deep learning models. Therefore, learning a discriminative feature is critical for person reidentification. Many works supervise the model learning with one or more loss functions to obtain the discriminability of features. Softmax loss is one of the widely used loss functions in re-id. However, traditional softmax loss inherently focuses on (...) the feature separability and fails to consider the compactness of within-class features. To further improve the accuracy of re-id, many efforts are conducted to shrink within-class discrepancy as well as between-class similarity. In this paper, we propose a circle-based ratio loss for person re-identification. Concretely, we normalize the learned features and classification weights to map these vectors in the hypersphere. Then we take the ratio of the maximal intraclass distance and the minimal interclass distance as an objective loss, so the between-class separability and within-class compactness can be optimized simultaneously during the training stage. Finally, with the joint training of an improved softmax loss and the ratio loss, the deep model could mine discriminative pedestrian information and learn robust features for the re-id task. Comprehensive experiments on three re-id benchmark datasets are carried out to illustrate the effectiveness of the proposed method. Specially, 83.12% mAP on Market-1501, 71.66% mAP on DukeMTMC-reID, and 66.26%/63.24% mAP on CUHK03 labeled/detected are achieved, respectively. (shrink)

Object perception deploys a suite of perceptual capacities that constrains attention, guides reidentification, subserves recognition, and anchors demonstrative thought. Objects for perception—perceptual objects—are the targets of such capacities. Characterizing perceptual objects for multisensory perception faces two puzzles. First is the diversity of objects across sensory modalities. Second is the unity of multisensory perceptual objects. This paper resolves the puzzles. Objects for perception are structured mereologically complex individuals. Perceptual objects are items that bear perceptible features and have perceptible parts (...) arranged to form a unified whole. This circumscribes the targets of object perception where neutral talk concerning intentional objects and objects of perception cannot. Nonetheless, it is more permissive than identifying perceptual objects with material bodies, which excludes too much and leans too heavily on vision. The account thus is tailored to capture the role of objects in perception beyond vision: tactual, auditory, and olfactory objects are individuals with differing structures. Its flexibility also enables the account to accommodate shared objects for multisensory perception: multisensory perceptual objects are mereologically complex individuals with hybrid structure. For instance, one can bimodally perceive a common whole with parts accessible to one but not both modalities. Each sense provides a partial perspective on a complex whole that is perceptible through the coordinated use of multiple senses. Understanding perceptual objects as structured mereologically complex individuals thus provides a theoretically useful notion of an object for multisensory perception that resolves the puzzles of diversity and of unity.

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.

My research takes as its guiding thread the statement from Hegel's lectures on the philosophy of spirit of 1805-06, that «cognition is recognition[Erkennen ist Anerkennen]». In this perspective I delineate, first, the consequences of this position for Hegel's epistemology, in particular with reference to the question of skepticism. Then, I show in what sense the recognitive conception of knowledge makes it possible for Hegel to comprehend unitarily, on one hand, cognition as exercise of natural capacities and cognition as exercise of (...) normative capacities socially articulated, and,on the other hand, theoretical self-consciousness and practical self-consciousness. The gnoseological importance of this solution can be comprehended only if we reconstruct the evolution of Hegel's thought in that span of time in which he most directly tackles the issue of skepsis: that is, from 1797 - the beginning of his Frankfurt period - when he began to occupy himself with gnoseological questions, until the end of his stay in Jena,which begins in 1801 and concludes in 1807 with the writing of the Phenomenology. The analysis of the development of the Hegelian theory of knowledge - worked out in the first part of my study - is dealt with in the context of a reconstruction of the historico-argumentative constellation within which it matured. The constellation of importance for our analysis is represented by the skeptical crisis - triggered by authors such as Schulze, Maimonand Platner - that invested the post-Kantian galaxy, within which the idealist solutions to the problem of cognition matured. Through the analysis of journals and authors with whom Hegel came directly or indirectly into contact - from Platner to Reinhold, Jacobi, Fichte and Schelling, to Hölderlin and Sinclair, concluding with Zeender, Krug, Bouterwek and Werneburg, and among the journals Fülleborn's Beiträge and Niethammer's Journal in particular - it is possible to map the various solutions proposed for the skeptical problem andsee how it is in relation to this problem that the conceptions of self-consciousness evolve and the very concept of "interpersonality" - "intersubjectivity" - emerges for the first time. At the same time, pursuing my objective of broadening the investigation of the phenomenon of recognition, which in my view is not reducible to the field of practical philosophy, I proposea fresh reconstruction of the lexical and conceptual evolution of the various terms -Erkennen, Wiedererkennen, Recognition, Anerkennen - through which the various modalities of the phenomenon of recognition were indicated in the philosophical tradition to which Hegel refers: recognition of objects as perceptive reidentification; reminiscence on the level of theory of memory; recognition of subjects as self-recognition (apperception) and attribution to others of intentionality; logical recognition as recognition of the validity of a proposition; moral recognition, where "recognizing" generally means approving, accepting(more specifically, someone may be "recognized" as an autonomous subject and as a unique,genuine individuality). I focus in particular on the theory of memory as «recognitio» in Wolff and in his school, on the conception of «reconnaissance» in Bonnet, on Kantian«Recognition» and on the theory of «Anerkennen» in Ernst Platner. This investigation serves, on the one hand, to show how the phenomenon of recognition is central for a comprehension of the structure both of the lower and of the higher cognitive faculties. This ought to allow us to understand in what sense Hegel, taking intersubjective recognition as hisleading phenomenon, attempts to reunite the various meanings of recognition within a theory of knowledge on the basis of which «cognition is recognition». On the other hand, my conceptual and lexicographic investigation also serves to bring to light - in a new way with respect to the studies on Anerkennung - a hitherto unknown problematic constellation and the input of certain authors, such as Werneburg and Platner, whose conceptions may haveinfluenced Hegel's approach.The second part and the third of my study - a reconstruction of the pre- phenomenological Jena writings dealing with «Anerkennung» - dwells on the theme of the notion of natural recognition, whose centrality for the Hegelian conception of recognition has not yet been adequately grasped. This reconstruction of the theory of natural recognition gives due weight to the influence of Schelling on Hegel's understanding of «Anerkennung» -while the critical literature has generally concentrated on Fichte. Analyzing the conception of the animal organism developed in particular in the lectures on the philosophy of nature of 1803-04 brings to light how Hegel already individuates the recognitive phenomenon at the level of sexual reproduction: it is from here that he posits the natural prerequisites for the development of consciousness of self. The category of natural recognition will present itself anew in Hegel's analysis of the social ontology of the human world in the philosophy of spirit, where it concerns sexual love, reproduction and child raising: natural recognition is, then, that on the basis of which Hegel develops his theory that cognition is recognition.Recognition, as a «middle» of spirit, is a cognitive phenomenon that is primitive with respectto linguistically structured human intersubjectivity; it is, properly, that cognitive structure which is necessarily presupposed by a self-conscious subjectivity that expresses itself linguistically: linguistic intersubjectivity expresses various modes of recognition, but notevery form of recognition is linguistic. The evolutional theory of cognition as recognition is in fact designed to show how increasingly complex recognitive relations emerge from a basic level of natural interactions to take on a linguistically mediated and universal structure. Withthe notion of spiritual recognition Hegel indicates just that ensemble of normative relations that constitute the infrastructure of action and thus mediate the formation of socially articulated self-conscious knowing of self. In the lectures on the philosophy of spirit of 1803-04 and of 1805-06 Hegel thus reconstructs the recognitive structure of the social institutions of right, of labor, and of exchange, showing that, within a politically structured community,dyadic (I-you) interactions are mediated by the universal viewpoint of the "we" incarnated in institutions that can be recognized by citizens as their own and by which citizens can be recognized.

Millikan (1998a) relies on the ability an organism may have to reidentify external objects. It is difficult to develop an account of how this might occur because the organism could make a mistake in the tokening of a concept; it could misidentify the external object. To sustain her nondescriptivism, Millikan's account of reidentification must make the link between concept and object arbitrary. However, to make mistakes possible, there must be a norm for the production of concepts. These (...) two requirements seem to leave no room for a middle ground. (shrink)

At present, person reidentification based on attention mechanism has attracted many scholars’ interests. Although attention module can improve the representation ability and reidentification accuracy of Re-ID model to a certain extent, it depends on the coupling of attention module and original network. In this paper, a person reidentification model that combines multiple attentions and multiscale residuals is proposed. The model introduces combined attention fusion module and multiscale residual fusion module in the backbone network ResNet 50 to enhance (...) the feature flow between residual blocks and better fuse multiscale features. Furthermore, a global branch and a local branch are designed and applied to enhance the channel aggregation and position perception ability of the network by utilizing the dual ensemble attention module, as along as the fine-grained feature expression is obtained by using multiproportion block and reorganization. Thus, the global and local features are enhanced. The experimental results on Market-1501 dataset and DukeMTMC-reID dataset show that the indexes of the presented model, especially Rank-1 accuracy, reach 96.20% and 89.59%, respectively, which can be considered as a progress in Re-ID.

We humans tend to believe that things are only real in as much as we perceive them, an idea reinforced by modern philosophy, which privileges us as special, radically different in kind from all other objects. But as Graham Harman, one of the theory's leading exponents, shows, Object-Oriented Ontology (OOO) rejects the idea of human specialness: the world, he states, is clearly not the world as manifest to humans. "To think a reality beyond our thinking is not nonsense, but (...) obligatory." At OOO's heart is the idea that objects--whether real, fictional, natural, artificial, human, or non-human--are mutually autonomous. This core idea has significance for nearly every field of inquiry which is concerned in some way with the systematic interaction of objects, and the degree to which individual objects resist full participation in such systems. In this brilliant new introduction, Graham Harman lays out OOO's history, ideas, and impact, taking in art and literature, politics and natural science along the way. From Sherlock Holmes, unicorns, and videogames to Dadaism, Voltaire, and string theory, this book will change the way you understand everything. (shrink)

This paper examines the idea of objective phenomenology, or a way of understanding the phenomenal character of conscious experiences that doesn’t require one to have had the kinds of experiences under consideration. My central thesis is that structural facts about experience—facts that characterize purely how conscious experiences are structured—are objective phenomenal facts. I begin by precisifying the idea of objective phenomenology and diagnosing what makes any given phenomenal fact subjective. Then I defend the view that structural facts about experience are (...) objective. I also argue that structural facts about experience, despite being objective, nevertheless still give rise to an explanatory gap. (shrink)

In this volume Rorty offers a Deweyan account of objectivity as intersubjectivity, one that drops claims about universal validity and instead focuses on utility for the purposes of a community. The sense in which the natural sciences are exemplary for inquiry is explicated in terms of the moral virtues of scientific communities rather than in terms of a special scientific method. The volume concludes with reflections on the relation of social democratic politics to philosophy.

Worries about scientific objectivity seem never-ending. Social critics and philosophers of science have argued that invocations of objectivity are often little more than attempts to boost the status of a claim, while calls for value neutrality may be used to suppress otherwise valid dissenting positions. Objectivity is used sometimes to advance democratic agendas, at other times to block them; sometimes for increasing the growth of knowledge, at others to resist it. Sandra Harding is not ready to throw out objectivity quite (...) yet. For all of its problems, she contends that objectivity is too powerful a concept simply to abandon. In Objectivity and Diversity, Harding calls for a science that is both more epistemically adequate and socially just, a science that would ask: How are the lives of the most economically and politically vulnerable groups affected by a particular piece of research? Do they have a say in whether and how the research is done? Should empirically reliable systems of indigenous knowledge count as "real science"? Ultimately, Harding argues for a shift from the ideal of a neutral, disinterested science to one that prizes fairness and responsibility. (shrink)

The idea that science is objective, or able to achieve objectivity, is in large part responsible for the role that science plays within society. But what is objectivity? The idea of objectivity is ambiguous. This paper distinguishes between three basic forms of objectivity. The first form of objectivity is ontological objectivity: the world as it is in itself does not depend upon what we think about it; it is independent of human thought, language, conceptual activity or experience. The second form (...) of objectivity is the objectivity of truth: truth does not depend upon what we believe or justifiably believe; truth depends upon the way reality itself is. The third form of objectivity is epistemic objectivity: this form of objectivity resides in the scientific method which ensures that subjective factors are excluded, and only epistemically relevant factors play a role in scientific inquiry. The paper considers two problems that arise for the notion of epistemic objectivity: the theory-dependence of observation and the variability of the methods of science. It is argued that the use of shared standard procedures ensures the objectivity of observation despite theory-dependence. It is argued that the variability of methods need not lead to epistemic relativism about science. The paper concludes with the realist suggestion that the best explanation of the success of the sciences is that the methods employed in the sciences are highly reliable truth-conducive tools of inquiry. The objectivity of the methods of the sciences leads to the objective truth about the objective world. (shrink)

Objects generate time; time does not generate or change objects. That is the central thesis of this book by the philosopher Graham Harman and the archaeologist Christopher Witmore, who defend radical positions in their respective fields. Against a current and pervasive conviction that reality consists of an unceasing flux-a view associated in philosophy with New Materialism-object-oriented ontology asserts that objects of all varieties are the bedrock of reality from which time emerges. And against the narrative convictions of time as (...) the course of historical events, the objects and encounters associated with archaeology push back against the very temporal delimitations which defined the field and its objects ever since its professionalization in the nineteenth century. In a study ranging from the ruins of ancient Corinth, Mycenae, and Troy to debates over time from Aristotle and al-Ash'ari through Henri Bergson and Alfred North Whitehead, the authors draw on alternative conceptions of time as retroactive, percolating, topological, cyclical, and generational, as consisting of countercurrents or of a surface tension between objects and their own qualities. Objects Untimely invites us to reconsider the modern notion of objects as inert matter serving as a receptacle for human categories"-. (shrink)

Building on self-professed perspectival approaches to both scientific knowledge and causation, I explore the potentially radical suggestion that perspectivalism can be extended to account for a type of objectivity in science. Motivated by recent claims from quantum foundations that quantum mechanics must admit the possibility of observer-dependent facts, I develop the notion of ‘perspectival objectivity’, and suggest that an easier pill to swallow, philosophically speaking, than observer-dependency is perspective-dependency, allowing for a notion of observer-independence indexed to an agent perspective. Working (...) through the case studies of colour perception and causal perspectivalism, I identify two places within which I claim perspectival objectivity is already employed, and make the connection to quantum mechanics through Bohr’s philosophy of quantum theory. I contend that perspectival objectivity can ensure, despite the possibility of perspective-dependent scientific facts, the objectivity of scientific inquiry. (shrink)

My goal in this paper is, to tentatively sketch and try defend some observations regarding the ontological dignity of object references, as they may be used from within in a formalized language. -/- Hence I try to explore, what properties objects are presupposed to have, in order to enter the universe of discourse of an interpreted formalized language. -/- First I review Frege′s analysis of the logical structure of truth value definite sentences of scientific colloquial language, to draw suggestions (...) from his saturated vs. unsaturated sentence components paradigm. -/- Next try investigate, in how far reference to non pure math objects might allow for a role as argument of a truth value function. Object kinds to be considered are: common sense objects, technical objects, humanities object kinds (social, psychical, ...), objects of art, ... , be they abstract, concrete, or in this respect mixed objects. -/- Then have a comment on the just referenced label abstract objects. -/- Next try to get an idea wrt the ontological significance of the fact, that pure math objects and functions in some important classical cases can be uniquely defined by means of categorical theories. Here, in the course of my argument, I have a little corollary wrt the standard model of first order Peano arithmetic, reducing the epistemological significance of the existence of the non standard models. -/- Next, wrt a special concept of a formalized empirical theory, I care for whether the impure math objects and mixed objects described here, and complying best with truth value function mapping, are also reliable candidates for the ontological commitment of such theories: and discuss an alternative, which reduces the ontological significance of the universe of discourse of the theories intended models. -/- In the end I sum up what is - from my point of view - the status quo, according to my respective findings.

Précis for a book symposium, with contributions from Meg Wallace, Louis deRosset, and Chris Tillman and Joshua Spencer.

Figal has long been recognized as one of the most insightful interpreters working in the tradition of philosophical hermeneutics and its leading themes concerned with ancient Greek thought, art, language, and history. With this book, Figal presses this tradition of philosophical hermeneutics in new directions. In his effort to forge philosophical hermeneutics into a hermeneutical philosophy, Figal develops an original critique of the objectification of the world that emerges in modernity as the first stage in his systematic treatment of the (...) elements of experience hermeneutically understood. Breaking through the prejudices of modernity, but not sacrificing the importance and challenge of the objective world that confronts us and is in need of interpretation, Figal reorients how it is that philosophy should take up some of its most longstanding and stubborn questions. World, object, space, language, freedom, time, and life are refreshed as philosophical notions here since they are each regarded as elements of human life engaged in the task assigned to each of us—the task of understanding ourselves and our world.

This paper argues for the philosophical and semantic importance of attitudinal objects, entities such as judgments, claims, beliefs, demands, and desires, as an ontological category distinct from that of events and states and from that of propositions. The paper presents significant revisions and refinements of the notion of an attitudinal object as it was developed in my previous work.

This paper defends the view that attitudinal objects such as claims, beliefs, judgments, and requests form an ontological category of its own sharply distinguished from that of events and states and that of propositions. Attitudinal objects play a central role in attitude reports and avoid the conceptual and empirical problems for propositions. Unlike the latter, attitudinal objects bear a particular connection to normativity. The paper will also discuss the syntactic basis of a semantics of attitude reports based on attitudinal objects.
