In this book, Roy Bhaskar sets out to revindicate ontology, critiquing the reduction of being in favor of knowledge, which he calls the "epistemic fallacy".

A groundswell of recent work in philosophy has sought to revitalize the analysis of causation by appealing to "active principles" such as powers, dispositions, capacities, tendencies, and propensities. These principles are described in a realist and rather Aristotelian fashion, in stark contrast to the deflationary and linguistic accounts of such principles characteristic of Humean thought and empiricist thinking more generally. Natures, essences, powers, and de re necessity are back in the analysis of causation. I do not argue in this paper (...) for the plausibility of the revitalization project in general; instead, I explain how I think one aspect of it must be understood if the project is to be plausible. I suggest that those who are moved to resist Humean austerity and embrace a realism about things such as causal powers should take care in how they formulate this realism. Some Aristotelian notions, such as the concept of a causal power, may well be useful to modern studies of causation. Others, such as the notion that causal powers are determined by essences which comprise the natures of things, are outmoded in many sciences today. This paper focuses specifically on the notions of power and essence in the context of causation. Contra some of the most important recent proponents of the revitalization project, I contend that causal generalizations are not generally best understood as determined by the essential properties of natural kinds. How a member of a kind (natural or otherwise) behaves causally may be a function of its causal powers, but such powers need not constitute anything like the "essence" of a kind. -/- 1.

In this sequence of philosophical essays about natural science, the author argues that fundamental explanatory laws, the deepest and most admired successes of modern physics, do not in fact describe regularities that exist in nature. Cartwright draws from many real-life examples to propound a novel distinction: that theoretical entities, and the complex and localized laws that describe them, can be interpreted realistically, but the simple unifying laws of basic theory cannot.

Now acknowledged as a classic in the philosophy of science, A Realist Theory of Science is one of the very few books to transform not only our understanding of science, but that of the nature of the world it studies. The book has inspired the multi-disciplinary and international movement of thought known as critical realism. Re-issued with a new introduction.

In considering the nature of properties four controversial decisions must be made. (1) Are properties universals or tropes? (2) Are properties attributes of particulars, or are particulars just bundles of properties? (3) Are properties categorical (qualitative) in nature, or are they powers? (4) If a property attaches to a particular, is this predication contingent, or is it necessary? These choices seem to be in a great degree independent of each other. The author indicates his own choices.

Hunting Causes and Using Them argues that causation is not one thing, as commonly assumed, but many. There is a huge variety of causal relations, each with different characterizing features, different methods for discovery and different uses to which it can be put. In this collection of new and previously published essays, Nancy Cartwright provides a critical survey of philosophical and economic literature on causality, with a special focus on the currently fashionable Bayes-nets and invariance methods - and it exposes (...) a huge gap in that literature. Almost every account treats either exclusively how to hunt causes or how to use them. But where is the bridge between? It's no good knowing how to warrant a causal claim if we don't know what we can do with that claim once we have it. This book will interest philosophers, economists and social scientists. (shrink)

Jennifer McKitrick offers an opinionated guide to the philosophy of dispositions. In her view, when an object has a disposition, it is such that, if a certain type of circumstance were to occur, a certain kind of event would occur. Since this is very common for this to be the case, dispositions are an abundant and diverse feature of our world.

George Molnar came to see that the solution to a number of the problems of contemporary philosophy lay in the development of an alternative to Hume's metaphysics. This alternative would have real causal powers at its centre. Molnar set about developing a thorough account of powers that might persuade those who remained, perhaps unknowingly, in the grip of Humean assumptions. He succeeded in producing something both highly focused and at the same time wide-ranging. He showed both that the notion of (...) a power was central and that it could serve to dispel a number of long-standing philosophical problems.Molnar's account of powers is as realist as any that has so far appeared. He shows that dispositions are as real as any other properties. Specifically, they do not depend for their existence on their manifestations. Nevertheless, they are directed towards such manifestations. Molnar thus appropriates the notion of intentionality, from Brentano, and argues that it is the essential characteristic of powers. He offers a persuasive case for there being some basic and ungrounded powers, thus ruling out the reducibility of the dispositional to the non-dispositional. However, he does allow that there are non-power properties as well as power properties. In this respect, his final position is dualistic.This is contemporary metaphysics of the highest quality. It is a work that was almost complete when its author died. It has been edited for publication by another specialist in the subject, Stephen Mumford, who has also provided an introduction that will allow non-specialists to become acquainted with the issues. David Armstrong, one of the greatest living metaphysicians and personal friend of George Molnar, has provided a Foreword. (shrink)

In this paper, I make the case for the view that there are many different kinds of dispositions, a view I call dispositional pluralism. The reason I think that this case needs to be made is to temper the tendency to make sweeping generalization about the nature of dispositions that go beyond conceptual truths. Examples of such generalizations include claims that all dispositions are intrinsic, essential, fundamental, or natural.! In order to counter this tendency, I will start by noting the (...) extent to which it is at odds with the semantics of dispositions, according to which there are many kinds of disposition ascriptions. From there, I will try to support a metaphysical claim that there are different kinds of dispositions. To bridge the gap between semantics and metaphysics, I appeal to epistemology. I'll consider the question "when do we have good reason to believe that a disposition ascription is true?" If our disposition ascriptions are true, then we are right about what kinds of dispositions things have, and what kinds of dispositions there are. I claim that our evidence for different kinds of dispositions is on a par; we have reason to believe that various kinds of dispositions are instantiated. (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).

I argue that realism about causal powers sublates the passivist, Humean-inflected free will problematic. In the first part of the paper I show that adopting what I call ‘powers-non-determinism’ reconfigures the conceptual terrain with respect to the causation component of the contemporary problematic. In part two I show how adopting ‘powers-non-determinism’ significantly alters the nature of the discussion with respect to the agency component of the problematic. In part three I compare ‘powers-non-determinism’ to an otherwise- Humean agent causal position.

For many years essentialism was considered beyond the pale in philosophy, a relic of discredited Aristotelianism. This is no longer so. Kripke and Putnam have made belief in essential natures respectable once more. Harré and Madden have argued against Hume's theory of causation and developed an alternative theory based on the assumption that there are genuine causal powers in nature. Dretske, Tooley, Armstrong, Swoyer, and Carroll have all developed strong alternatives to Hume's theory of the laws of nature. And Shoemaker (...) has developed a thoroughly non-Humean theory of properties. The "new essentialism" has evolved from these beginnings and can now reasonably claim to be a metaphysic for a modern scientific understanding of the world - one that challenges the conception of the world as comprising passive entities whose interactions are to be explained by appeal to contingent laws of nature externally imposed.

In "The Philosophy of Nature," Brian Ellis provides a clear and forthright general summation of, and introduction to, the new essentialist position. Although the theory that the laws of nature are immanent in things, rather than imposed on them from without, is an ancient one, much recent work has been done to revive interest in essentialism and "The Philosophy of Nature" is a distinctive contribution to this lively current debate. Brian Ellis exposes the philosophical and scientific credentials of the prevailing (...) Humean metaphysic as less than compelling and makes the case for new essentialism as an alternative metaphysical perspective in lucid and unambiguous terms. This book develops this alternative metaphysic and considers the consequences for philosophy, and for some other areas of investigation, of working with such a metaphysic. Ellis argues that these consequences are profound and that a new essentialism provides a comprehensive new philosophy of nature for a modern scientific understanding of the world. (shrink)

Individual objects have potentials: paper has the potential to burn, an acorn has the potential to turn into a tree, some people have the potential to run a mile in less than four minutes. Barbara Vetter provides a systematic investigation into the metaphysics of such potentials, and an account of metaphysical modality based on them. -/- In contemporary philosophy, potentials have been recognized mostly in the form of so-called dispositions: solubility, fragility, and so on. Vetter takes dispositions as her starting (...) point, but argues for and develops a more comprehensive conception of potentiality. She shows how, with this more comprehensive conception, an account of metaphysical modality can be given that meets three crucial requirements: Extensional correctness: providing the right truth-values for statements of possibility and necessity; formal adequacy: providing the right logic for metaphysical modality; and semantic utility: providing a semantics that links ordinary modal language to the metaphysics of modality. -/- The resulting view of modality is a version of dispositionalism about modality: it takes modality to be a matter of the dispositions of individual objects. This approach has a long philosophical tradition going back to Aristotle, but has been largely neglected in contemporary philosophy. In recent years, it has become a live option again due to the rise of anti-Humean, powers-based metaphysics. The aim of Potentiality is to develop the dispositionalist view in a way that takes account of contemporary developments in metaphysics, logic, and semantics. (shrink)

Ontology. Revisited. Groff's argument cuts against a familiar anti-metaphysical grain. Social and political philosophy, she maintains, is not as metaphysically neutral as it may seem. Even the most deontological of theories connects up with a ...

Causation is everywhere in the world: it features in every science and technology. But how much do we understand it? Mumford and Anjum develop a new theory of causation based on an ontology of real powers or dispositions. They provide the first detailed outline of a thoroughly dispositional approach, and explore its surprising features.

This book outlines a major new theory of natural laws. The book begins with the question of whether there are any genuinely law-like phenomena in nature. The discussion addresses questions currently being debated by metaphysicians such as whether the laws of nature are necessary or contingent and whether a property can be identified independently of its causal role.

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.

Scientific Essentialism defends the view that the fundamental laws of nature depend on the essential properties of the things on which they are said to operate, and are therefore not independent of them. These laws are not imposed upon the world by God, the forces of nature or anything else, but rather are immanent in the world. Ellis argues that ours is a dynamic world consisting of more or less transient objects which are constantly interacting with each other, and whose (...) identities depend on their roles in these processes. Natural objects must behave as they do, because to do otherwise would be contrary to their natures. The laws of nature are, therefore, metaphysically necessary, and consequently, there are necessary connections between events. Brian Ellis calls for the rejection of the theory of Humean Supervenience and an implementation of a new kind of realism in philosophical analysis. (shrink)

Professional philosophers and advanced students working in metaphysics and the philosophy of science will find this book both provocative and stimulating.

I argue that a powers-based metaphysics radically reconfigures the existing free will problematic. This is different from claiming that such an approach solves the ill-conceived problems that emerge from Humean-Kantian default commitments.
