This volume deals primarily with absentology, an ontological and social-scientific epistemological mode, dedicated to the analysis of absence. The book is drawn by manifestations of absence wherever they may be encountered. It deals with three terms, ‘the shadow economy’, ‘corruption’ and ‘pollution’, while constructing a non-realist ontology predicated upon the emptiness of all predicates, as expounded by certain strands of Hindu and Buddhist philosophy. According to the absentological viewpoint, there is nothing outside, beyond, below or above relations. Relations exist on their own, enchained within an immense, infinite regress, opening and closing upon one another. Absentology is, by consequence of its nonattachment to phenomena, a form of social inquiry fundamentally alien to each and every social form, and it abandons any illusions about the possibility of an escape from the realm of relationality. This book will appeal to students and academics interested in ontological philosophy.

Over the past few decades, there has been a renewal of scholarly interest in the work of Henri Bergson (1859–1941). At once a commentary and a stark re-evaluation of Bergson’s philosophy, Updating Bergson: A Philosophy of the Enduring Present argues that time should be thought of as a hierarchy of simultaneous durations, the shifting reality of which can be revealed by the philosophical method of intuition. A duration is a perpetually dynamic flow situated in the now. Put simply, for Bergson, change is the substance of things. Nothing exists apart from alteration. Adam Lovasz analyzes Bergson’s philosophy of time, encompassing the three basic types of duration—material, organic, and subjective—and also touches on themes such as relativity, evolution, the problem of materialism and idealism, and the topic of free will. Lovasz connects key questions addressed by Bergson to contemporary scientific debates and paradigms. Shedding new light on the various aspects of Bergson's philosophy, this book is both a provocation and an invitation to think in terms of the enduring present, rather than committing ourselves to a dead past or an absent future.

Ontology was once understood to be the philosophical inquiry into the structure of reality: the analysis and categorization of ‘what there is’. Recently, however, a field called ‘ontology’ has become part of the rapidly growing research industry in information technology. The two fields have more in common than just their name. Theory and Applications of Ontology is a two-volume anthology that aims to further an informed discussion about the relationship between ontology in philosophy and ontology in information technology. It fills an important lacuna in cutting-edge research on ontology in both fields, supplying stage-setting overview articles on history and method, presenting directions of current research in either field, and highlighting areas of productive interdisciplinary contact. Theory and Applications of Ontology: Philosophical Perspectives presents ontology in philosophy in ways that computer scientists are not likely to find elsewhere. The volume offers an overview of current research traditions in ontology, contrasting analytical, phenomenological, and hermeneutic approaches. It introduces the reader to current philosophical research on those categories of everyday and scientific reasoning that are most relevant to present and future research in information technology.

This posthumous work by Gustav Bergmann was essentially complete before his death in 1987. In it, he proposes a systematic ontological system that would account for all the basic areas of human thought and experience within an extended framework of logical atomism. Bergmann's approach to traditional problems of ontology seeks to balance the competing demands of phenomenology, which emphasizes the reality presented to us by experience, and of metaphysics, which delineates the most general kinds of existents given in experience and the most general kinds of relationships they bear to one another. Beginning with atomic facts composed of phenomenally presented qualities, Bergmann goes on to develop an ontology that can account for the ordinary objects of everyday experience, the mental states through which we become aware of and acquire knowledge of these objects, and even the truths of logic and mathematics that allow us to extend our thought and discourse about ordinary objects beyond what may be phenomenally apparent. Many ontologists will be particularly interested in the attention Bergmann pays to the concept of logical form. In his earlier works, Bergmann claimed that "the form of the world is in the world"; the "fact" that a thing or a complex has a certain logical or syntactic form, he argued, is itself one more fact of our experienced reality, rather than a contribution of the mind or of linguistic conventions. Critics of this claim have suggested that paradoxes and contradictions result from it. In New Foundations of Ontology Bergmann responds, arguing that his concept of logical form does not necessarily create the problems noted in earlier critiques.

The philosophical study of what exists and what it means for something to exist is one of the core concerns of metaphysics. This introduction to ontology provides readers with a comprehensive account of the central ideas of the subject of being. This book is divided into two parts. The first part explores questions of pure philosophical ontology: what is meant by the concept of being, why there exists something rather than nothing, and why there is only one logically contingent actual world. Dale Jacquette shows how logic provides the only possible answers to these fundamental problems. The second part of the book examines issues of applied scientific ontology. Jacquette offers a critical survey of some of the most influential traditional ontologies, such as the distinction between appearance and reality, and the categories of substance and transcendence. The ontology of physical entities - space, time, matter and causation - is examined as well as the ontology of abstract entities such as sets, numbers, properties, relations and propositions. The special problems posed by the subjectivity of mind and of postulating a god are also explored in detail. The final chapter examines the ontology of culture, language and art.
