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.

The newest addition to the successful Oxford Readings in Philosophy series, this collection contains the most important contributions to the recent debate on the philosophy of science. The contributors crystallize the often heated arguments of the last two decades, assessing the skeptical attitudes within philosophy of science and the counter-challenges of the scientific realists. Contributors include Nancy Cartwright, Brian Ellis, Arthur Fine, Clark Glymour, Larry Laudan, Peter Lipton, Alan Musgrave, Wesely C. Salmon, Lawrence Sklar, Bas C. van Fraassen, and John (...) Worrall. (shrink)

The book is drawn from the Tarner lectures, delivered in Cambridge in 1993. It is concerned with the ultimate nature of reality, and how this is revealed by modern physical theories such as relativity and quantum theory. The objectivity and rationality of science are defended against the views of relativists and social constructionists. It is claimed that modern physics gives us a tentative and fallible, but nevertheless rational, approach to the nature of physical reality. The role of subjectivity in science (...) is examined in the fields of relativity theory, statistical mechanics and quantum theory, and recent claims of an essential role for human consciousness in physics is rejected. Prospects for a 'Theory of Everything' are considered, and the related question of how to assess scientific progress is carefully examined. (shrink)

Subsequent to the transition from the era of natural philosophy to what we now regard as the era of the modern sciences, the latter have often been described as independent of the major philosophical preoccupations that previously informed theorizing about the natural world. The extent to which this is a naïve description is a matter of debate, and in particular, views of the place of metaphysics in the interpretation of modern scientific knowledge have varied enormously. Logical positivism spawned a distaste (...) for metaphysics in the philosophy of science which lasts to this day, but in recent years, a renaissance in analytic metaphysics has been embraced by a growing number of philosophers of science. Those moved by distaste commonly subscribe either to a minimalist Humean metaphysic, or to a quietism about metaphysical questions generally. Those moved by attraction contend that metaphysical investigations into the natures of things like properties, causation, laws, and modality, are required in order to interpret descriptions of the world furnished by our best scientific theories. I consider the presuppositions separating these contemporary approaches to the philosophy of science, and the prospect of their resolution. (shrink)

In this paper I argue that physics makes metaphysical presuppositions concerning the physical comprehensibility, the dynamic unity, of the universe. I argue that rigour requires that these metaphysical presuppositions be made explicit as an integral part of theoretical knowledge in physics. An account of what it means to assert of a theory that it is unified is developed, which provides the means for partially ordering dynamical physical theories with respect to their degrees of unity. This in turn makes it possible (...) to assess the empirical fruitfulness of (some) metaphysical theses, in terms of the extent to which they play a role in empirically progressive scientific research programmes. A new conception of physics is developed which makes metaphysical theses an integral part of physics and which, at the same time, makes it possible to assess such theses in terms of their empirical fruitfulness. Circularity objections are rebutted. (shrink)

The main puzzle about theoretical definitions is that nothing seems to decide which assumptions contribute to such definitions and which do not. I argue that theoretical definitions are indeed imprecise, but that this does not normally matter, since the definitional imprecision does not normally produce indeterminacy of referential value. Sometimes, however, the definitional imprecision is less benign, and does generate referential indeterminacy. In these special cases, but not otherwise, it is necessary to refine the term's definition.

Analytic metaphysics is in resurgence; there is renewed and vigorous interest in topics such as time, causation, persistence, parthood and possible worlds. We who share this interest often pay lip-service to the idea that metaphysics should be informed by modern science; some take this duty very seriously.2 But there is also a widespread suspicion that science cannot really contribute to metaphysics, and that scientific findings grossly underdetermine metaphysical claims. For some, this prompts the thought ‘so much the worse for metaphysics’; (...) others mutter ‘so much the worse for science’. (shrink)

This is a critical, but sympathetic, examination of the manifesto for naturalized metaphysics that forms the first chapter of James Ladyman and Don Ross's 2006 book, Every Thing Must Go, but it has wider implications than this description suggests.

According to logical positivism, so the story goes, metaphysical questions are meaningless, since they do not admit of empirical confirmation or refutation. However, the logical positivists did not in fact reject as meaningless all questions about for example, the structure of space and time. Rather, key figures such as Reichenbach and Schlick believed that scientific theories often presupposed a conceptual framework that was not itself empirically testable, but which was required for the theory as a whole to be empirically testable. (...) For example, the theory of Special Relativity relies upon the simultaneity convention introduced by Einstein that assumes that the one-way speed of light is the same in all directions of space. Hence, the logical positivists accepted an a priori component to physical theories. However, they denied that this a priori component is necessarily true. Whereas for Kant, metaphysics is the a priori science of the necessary structure of rational thought about reality , the logical positivists were forced by the history of science to accept that the a priori structure of theories could change. Hence, they defended a notion of what Michael Friedman calls the ‘relativised’ or the ‘constitutive’ a priori. Carnap and Reichenbach held that such an a priori framework was conventional, whereas Schlick seems to have been more of a realist and held that the overall relative simplicity of different theories could count as evidence for their truth, notwithstanding the fact that some parts of them are not directly testable. All this is part of the story of how the verification principle came to be abandoned, and how logical positivism transmuted into logical empiricism. (shrink)

This book argues that the only kind of metaphysics that can contribute to objective knowledge is one based specifically on contemporary science as it really is, and not on philosophers' a priori intuitions, common sense, or simplifications of science. In addition to showing how recent metaphysics has drifted away from connection with all other serious scholarly inquiry as a result of not heeding this restriction, this book demonstrates how to build a metaphysics compatible with current fundamental physics, which, when combined (...) with metaphysics of the special sciences, can be used to unify physics with the other sciences without reducing these sciences to physics itself. Taking science metaphysically seriously, this book argues, means that metaphysicians must abandon the picture of the world as composed of self-subsistent individual objects, and the paradigm of causation as the collision of such objects. The text assesses the role of information theory and complex systems theory in attempts to explain the relationship between the special sciences and physics, treading a middle road between the grand synthesis of thermodynamics and information, and eliminativism about information. The consequences of the books' metaphysical theory for central issues in the philosophy of science are explored, including the implications for the realism versus empiricism debate, the role of causation in scientific explanations, the nature of causation and laws, the status of abstract and virtual objects, and the objective reality of natural kinds.

Recent philosophy of science has been seized by what may appear a schizophrenic attitude towards analytic metaphysics. Some philosophers of science have embraced metaphysical theorizing as an important tool for interpreting and extending scientific theories, while others reject analytic metaphysics as misguided, futile, or epistemically impotent. The idea of naturalized metaphysics—metaphysics appropriately ‘grounded’ in the details of empirical science—offers one possibility of a rapprochement between these seemingly conflicting attitudes. In this chapter, however, it is argued that the crucial notion of (...) ‘grounding’, and hence the idea of naturalized metaphysics itself, have not yet been articulated in a compelling manner. The beginnings of an articulation are sketched. (shrink)

Some philosophers argue that many contemporary debates in metaphysics are “illegitimate,” “shallow,” or “trivial,” and that “contemporary analytic metaphysics, a professional activity engaged in by some extremely intelligent and morally serious people, fails to qualify as part of the enlightened pursuit of objective truth, and should be discontinued” (Ladyman and Ross, Every thing must go: Metaphysics naturalized , 2007 ). Many of these critics are explicit about their sympathies with Rudolf Carnap and his circle, calling themselves ‘neo-positivists’ or ‘neo-Carnapians.’ Yet (...) despite the fact that one of the main conclusions of logical positivism was that metaphysical statements are meaningless, many of these neo-positivists are themselves engaged in metaphysical projects. This paper aims to clarify how we may see a neo-positivist metaphysics as proceeding in good faith, one that starts with serious engagement with the findings of science, particularly fundamental physics, but also has room for traditional, armchair methods.

This is a collection of articles which represents current research on the metaphysics of causation and laws of nature, mostly by authors working in or active in the Australasian region. The book provides an overview of current work on the theory of causation, including counterfactual, singularist, nomological and causal process approaches. It also covers work on the nature of laws of nature, with special emphasis on the scientific essentialist theory that laws of nature are, at base, the fundamental dispositions or (...) capacities of natural kinds of things. Because the book represents a good cross-section of authors currently working on these themes in the Australasian region, it conveys something of the interest and excitement of an active philosophical debate between advocates of several different research programmes in the area.

Wisely, the authors begin this book by describing it as a polemic. They argue that most contemporary analytic metaphysics is a waste of time and resources since contemporary ‘neo-scholastic’ metaphysical theorizing cannot hope to attain objective truth given its penchant for making a priori claims about the nature of the world which are backed up by appeal to intuition. In engaging in this activity, metaphysicians have, the authors claim, abandoned hope of locating any interesting connection between their metaphysical pronouncements and (...) how our best empirical theories describe the world. Moreover, the success attained by empirical science just cannot be matched by metaphysical theorizing and so, faced with this asymmetry, empirical science wins: a priori metaphysical theorizing must give way to a naturalistic form of metaphysics, a positive account of which the authors attempt to elucidate in the second and third, rather lengthy chapters of the book.The first chapter consists of a statement of the authors’ negative view, a vigorous, sustained and sometimes withering attack upon contemporary a priori metaphysics. Most ire is reserved for those who indulge in what the authors call ‘pseudo-scientific metaphysics’; that is, those who pay lip service to keeping their metaphysical speculation in tune with physics, only to constrain their ontology in such a way that the entities and processes within it do not even play a role in current physical theory, or are in straightforward contradiction with it. Much philosophy of science and scientific metaphysics is too superficial and simplistic to deserve the name and bears more relation to ‘the philosophy of “A” Level chemistry’. The guilty in this respect include David Lewis, Jaegwon Kim, Jonathan Lowe, Donald Davidson, Jerry Fodor, Crawford Elder, Trenton Merricks among …. (shrink)

Legitimating the use of metaphysics in scientific research constituted a farreaching methodological revolution, invalidating the inductivist demands that science be guided by empirical information alone. Thus, science became tentative. The revolution was established when pioneering historians of science, Max Jammer among them, exhibited the working of metaphysics in scientific research. This raises many problems, since most metaphysical ideas are poor as compared with scientific ones. Yet taking science to be the effort to explain facts in a comprehensive manner, makes some (...) metaphysics unavoidable, and presents the better metaphysics as the possible frameworks within which older scientific theories may be reinterpreted and improved and newer ones may be developed. (shrink)

The paper argues for three theses: Metaphysics depends on science as a source of knowledge. Our current scientific theories commit us to certain metaphysical claims. As far as science is concerned, it is sufficient to spell these claims out in such a way that they amount to a parsimonious ontology. That ontology, however, creates a gap between our experience and the scientific view of the world. In order to avoid that gap and to achieve a complete and coherent view of (...) the world including ourselves, we have to enrich that ontology at its foundations, thus making it less parsimonious. The criterion of the integration into a complete and coherent view of the world including ourselves is the way in which the interpretation of scientific theories depends on metaphysics. These three theses are argued for and illustrated by means of two examples from the philosophy of time and the philosophy of mind. (shrink)

This chapter explores some issues having to do with the structure of the evidential reasoning we use to infer causal and lawful claims. It is argued that such reasoning always makes use of prior, causally, or nomologically committed information, thus undercutting various views that attempt to reduce causal and lawful claims to claims about regularities. A non-reductive account of laws and causes built around the notion of invariance is advanced as an alternative.

Joseph Agassi is a critic, a gadfly, a debunker and deflater; he is also a constructor, a speculator and an imaginative scholaro In the history and philosophy of science, he has been Peck's bad boy, delighting in sharp and pungent criticism, relishing directness and simplicity, and enjoying it all enormously. As one of that small group of Popper's students (ineluding Bartley, Feyerabend and Lakatos) who took Popper seriously enough to criticize him, Agassi remained his own man, holding Popper's work itself (...) to the criteria of critical refutation. Agassi's range is wide and his publications proliik. He has published serious studies in the historiography of science, applied sociology (on Hong Kong with LC. Jarvie), foundations of anthropology, interpretive scientific biography (Faraday), Judaic studies, philosophy of technology (which Agassi pioneered, particulady in distinguishing it from the philosophy of science), as weIl as the many works on the Iogic, methodoI­ ogy, and history of science. Even as we go to press, Agassi's works are appearing; we append an imperfect and selected bibliography. For Agassi, the test of relevance is whether something is interesting. (shrink)

Peirce's Scientific Metaphysics is the first book devoted to understanding Charles Sanders Peirce's (1839-1914) metaphysics from the perspective of the scientific questions that motivated his thinking. While offering a detailed account of the scientific ideas and theories essential for understanding Peirce's metaphysical system, this book is written in a manner accessible to the non-specialist.

The paper argues that metaphysics depends upon science when it comes to claims about the constitution of the real world. That thesis is illustrated by considering the examples of global supervenience, the tenseless vs. the tensed theory of time and existence, events vs. substances, and relations vs. intrinsic properties. An argument is sketched out for a metaphysics of a four-dimensional block universe whose content are events and their sequences, events consisting in physical properties instantiated at space-time points, these properties being (...) relations rather than intrinsic properties.
