The purpose of the book is to clarify the notion of existential dependence and cognate notions, such as supervenience and the notion of an internal relation. I defend the view that such notions are best understood in terms of the concept of metaphysical grounding, i.e. the concept of one fact obtaining in virtue of other facts, where ‘in virtue of’ has a distinctively metaphysical meaning.

The concept of a trope (understood as an individual property and not as a figure of speech) plays an important role in contemporary analytical metaphysics. It is, however, often far from clear what the logic of this concept really is. Indeed, there are two equally important intuitions underlying the concept of trope, two intuitions that generate two quite different conceptual frameworks. According to the first intuition, a trope is a particularised property – a property taken as an individual aspect of (...) a particular object. A trope is thus the colour of this table or the shape of this sculpture. In the light of this conception tropes are, as it were, direct abstractions from concrete individuals. According to the second intuition a trope is still such an individual (and abstract) colour or such an individual (and abstract) shape, but now it is not only abstracted from the concrete individual of which it is a trope but also taken in abstraction from the very fact that it has been abstracted this way. We can imagine that the cognitive access to these tropes is obtained by a kind of a double abstraction. All this can sound puzzling at first blush, but in what follows I hope to make the matter a little clearer. Let us anticipate briefly. On the second view, tropes are construed not so much as abstractions from concrete individuals, but rather as primitive items of which the concrete individuals are composed. Tropes so construed are, as it were, metaphysically prior to concrete individuals. We will call tropes of this kind unstructured tropes, whereas tropes conceived as aspects of individual things will be called propositional tropes. This terminology is justified because tropes understood as aspects of things seem to involve something like propositional structure, a structure that tropes conceived as primitive “building blocks” of reality definitely lack. It is sometimes believed that these two concepts of trope are nearly equivalent, that the difference between them is for the most part verbal. Yet it will turn out that there is an important ontological difference here. Propositional tropes are non-trivially propositional and unstructured tropes are non-trivially deprived of such a structure (althought not necessarily deprived of any dependence-links with respect to other tropes). It will be argued that tropes are metaphysically interesting only on the second conception (i.e., as primitive, unstructured items), whereas only on the first conception (tropes as propositionally structured entities) can they function as semantically efficient truthmakers. The moral of the paper will be that our trust in tropes must be mitigated. A trope ontology could plausibly be viewed as a serious metaphysical alternative, but its semantical possibilities should not be exaggerated. (shrink)

From an Ontological Point of View is a highly original and accessible exploration of fundamental questions about what there is. John Heil discusses such issues as whether the world includes levels of reality; the nature of objects and properties; the demands of realism; what makes things true; qualities, powers, and the relation these bear to one another. He advances an account of the fundamental constituents of the world around us, and applies this account to problems that have plagued recent work (...) in the philosophy of mind and metaphysics (color, intentionality, and the nature of consciousness).

In this paper I argue that there are in fact external relations in Russell’s sense. The level at which we are forced to acknowledge them is, however, not the level of relations between concrete individual objects. All relations of this kind, which I will call “inter-individual” relations, can be construed as supervenient on the monadic properties of their terms. But if we pursue our ontological analysis a little bit deeper and consider the internal structure of a concrete individual, then we (...) will inevitably find irreducible external relations. I mean for example the relation of instantiation (in the frame of a realist’s theory) or that of concurrence (in the frame of a trope theory). I will show that such “intra-individual” relations – the relations that make up the internal structure of a concrete individual out of more primitive metaphysical “building blocks” like universals or tropes – could not (even in principle) be construed as supervenient.

Roman Ingarden, one of Husserl's closest students and friends, ranks among the most eminent of the first generation of phenomenologists. His magisterial <I>Controversy over the Existence of the World, written during the years of World War II in occupied Poland, consists of a fundamental defense of realism in phenomenology. Volume I, which receives here its first complete and critical translation into English, initiates the grand project of refuting transcendental idealism, and begins by setting the foundations for an elaborate and precise (...) ontological system. This is Ingarden's greatest accomplishment, who is rather known as a theoretician of literature than an ontologist outside of Poland. The most important achievement of Ingarden's ontology is an analysis of the modes of being of various types of objects - things, processes, events, purely intentional objects and ideas. The three-volume <I>Controversy is perhaps the last great systematic work in the history of philosophy, and undoubtedly one of the most important works in 20th century philosophical literature.

This PhD thesis presents some of my earlier attempts to develop a trope bundle theory. It contains a fairly comprehensive discussion of Simons' (1994, 1998) views and Denkel's (1995, 1996) Saturation Theory, which might still be useful.

In this paper, I explore several versions of the bundle theory and the substratum theory and compare them, with the surprising result that it seems to be true that they are equivalent (in a sense of 'equivalent' to be specified). In order to see whether this is correct or not, I go through several steps : first, I examine different versions of the bundle theory with tropes and compare them to the substratum theory with tropes by going through various standard (...) objections and arguing for a tu quoque in all cases. Emphasizing the theoretical role of the substratum and of the relation of compresence, I defend the claim that these views are equivalent for all theoretical purposes. I then examine two different versions of the bundle theory with universals, and show that one of them is, here again, equivalent to the substratum theory with universals, by examining how both views face the famous objection from Identity of Indiscernibles in a completely parallel way. It is only the second, quite extreme and puzzling, version of the bundle theory with universals that is not be equivalent to any other view; and the diagnosis of why this is so will show just how unpalatable the view is. Similarly, only a not-so-palatable version of the substratum theory is genuinely different from the other views; and here again it's precisely what makes it different that makes it less appealing.

Ontological dependence is a relation—or, more accurately, a family of relations—between entities or beings. For there are various ways in which one being may be said to depend upon one or more other beings, in a sense of “depend” that is distinctly metaphysical in character and that may be contrasted, thus, with various causal senses of this word. More specifically, a being may be said to depend, in such a sense, upon one or more other beings for its existence or (...) for its identity. Some varieties of ontological dependence may be analyzed in modal terms—that is, in terms of distinctly metaphysical notions of possibility and necessity—while others seem to demand an analysis in terms of the notion of essence. The latter varieties of ontological dependence may accordingly be called species of essential dependence. Notions of ontological dependence are frequently called upon by metaphysicians in their proposed analyses of other metaphysically important notions, such as the notion of substance. (shrink)

The thirty chapters work through various fundamental metaphysical issues, sometimes focusing more on scholastic thought, sometimes on the seventeenth century.

E. J. Lowe, a prominent figure in contemporary metaphysics, sets out and defends his theory of what there is. His four-category ontology is a metaphysical system which recognizes four fundamental categories of beings: substantial and non-substantial particulars and substantial and non-substantial universals. Lowe argues that this system has an explanatory power which is unrivalled by more parsimonious theories and that this counts decisively in its favour. He shows that it provides a powerful explanatory framework for a unified account of causation, (...) dispositions, natural laws, natural necessity and many other related matters, thus constituting a full metaphysical foundation for natural science.

_Metaphysics: A Contemporary Introduction_ is for students who have already completed an introductory philosophy course and need a fresh look at the central topics in the core subject of metaphysics. It is essential reading for any student of the subject. This Fourth Edition is revised and updated and includes two new chapters on Parts and Wholes, and Metaphysical Indeterminacy or vagueness. This new edition also keeps the user-friendly format, the chapter overviews summarizing the main topics, concrete examples to clarify difficult (...) concepts, annotated further reading at the end of each chapter, endnotes, and a full bibliography. Topics addressed include: the problem of universals the nature of abstract entities the problem of individuation the nature of modality identity through time the nature of time the nature of parts and wholes the problem of metaphysical indeterminacy the Realism/anti-Realism debate. Wherever possible, Michael J. Loux and Thomas M. Crisp relate contemporary views to their classical sources in the history of philosophy. As experienced teachers of philosophy and important contributors to recent debates, Loux and Crisp are uniquely qualified to write this book. (shrink)

John Heil's new book (Heil 2003) is remarkable in many ways. In a concise, lucid and accessible manner, it develops a complete system of ontology with many strikingly original features and then applies that ontology to fundamental issues in the philosophy of mind, with illuminating results. Although Heil acknowledges his intellectual debts to C. B. Martin (p. viii), he is unduly modest about his own contribution to the development and application of this novel metaphysical system. A full examination of the (...) position that Heil defends would require a book in itself, so I shall limit myself to discussing some of its central themes and to explaining a few doubts that I have concerning some aspects of it.

The distinction between the essence of an object and its properties has been obscured in contemporary discussion of essentialism. Locke held that the properties of an object are exclusively those features that ‘flow’ from its essence. Here he follows the Aristotelian theory, leaving aside Locke’s own scepticism about the knowability of essence. I defend the need to distinguish sharply between essence and properties, arguing that essence must be given by form and that properties flow from form. I give a precise (...) definition of what the term of art ‘flow’ amounts to, and apply the distinction to various kinds of taxonomic issues. (shrink)

_Varieties of Things: Foundations of Contemporary Metaphysics_ is about some of the most fundamental kinds of things that there are; the things that we encounter in everyday experience. A book about the things that we encounter in everyday experience. Contains a thorough and accessible discussion of the nature and aims of metaphysics. Examines a wide range of ontological categories, including both particulars and universals. Mounts a forceful and persuasive case for anti-reductionism.

The paper is a contribution to the object ontology. The general approach assumed in the investigation is that of Roman Ingarden's The Controversy Over the Existence of the World where an object is the subject-of-properties. The analysis of the form and the mode of existence of properties leads to the rejection of both negative and general properties. Each property is an individual qualitative moment of a particular object. Its form reveals existential heteronomy: the quality of the property is not immanent (...) but refers to the object. The subject of properties has not its own qualitative content: its form is just the internal causality establishing the unity of an object. An object is not causally isolated from other objects, but external causation differs from internal either by being ramified in case of the composition and destruction of an object or reciprocal in case of interaction between coexisting objects.

Professor Arda Denkel argues here that objects are nothing more than bundles of properties. From this point of view he tackles some central questions of ontology: how is an object distinct from others; how does it remain the same while it changes through time? A second contention is that properties are particular entities restricted to the objects they inhabit. The appearance that they exist generally, in a multitude of things, is due to the way we conceptualize them. Other problems dealt (...) with include how objects bear similarities by belonging to the same kinds, and how change in them is caused. Denkel defends a thoroughgoing particularism and offers purely qualitative accounts of individuation, identity, essences and matter. Throughout, the main alternative positions are surveyed, and the relevant historical background is traced. (shrink)
