What is empiricism and what could it be? Bas . van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition.

I examine the current state of the debate on the metaphysics of science. In 1, I identify some of the main questions belonging to the MS, looking into the relationship between science and metaphysics. In 2, I expound the rise of the old wave in the MS, which endorses the belief that metaphysics is a guide to, or a heuristic for, science and outlines the stronger idea that metaphysics makes science possible. In 3, I examine the maximalist MS. This is (...) a contemporary revival of the old wave, reformulating the claim that metaphysics makes science possible. In 4, I look into the new wave in the MS, which argues that science is a guide to metaphysics and, more radically, that metaphysics is to be motivated by, and restricted to, science. In 5, I briefly introduce my own minimalist MS, which contends that science sets the epistemic, methodological and ontological criteria which should work as desiderata of the MS. I close this chapter in 6 with some concluding remarks. (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.

While there are many examples of metaphysical theorising being heuristically and intellectually important in the progress of scientific knowledge, many people wonder how metaphysics not closely informed and inspired by empirical science could lead to rival or even supplementary knowledge about the world. This paper assesses the merits of a popular defence of the a priori methodology of metaphysics that goes as follows. The first task of the metaphysician, like the scientist, is to construct a hypothesis that accounts for the (...) phenomena in question. It is then argued that among the possible metaphysical theories, the empirical evidence underdetermines the right one, just as the empirical evidence underdetermines the right scientific theory. In the latter case it is widely agreed that we must break the underdetermination by appeal to theoretical virtues, and this is just what should be and largely is done in metaphysics. This is part of a more general line of argument that defends metaphysics on the basis of its alleged continuity with highly theoretical science. In what follows metaphysics and theoretical science are compared in order to see whether the above style of defence of a priori metaphysics is successful. (shrink)

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)

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.

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.

Science and philosophy both express, and attempt to quench, the distinctively human thirst for knowledge. Today, their mutual relationship has become one of conflict or indifference rather than cooperation. At the same time, scientists and philosophers alike have moved away from at least some of our ordinary beliefs. But what can scientific and philosophical theories tell us about the world, in isolation from each other? And to what extent does a sophisticated investigation into the nature of things force us to (...) question commonsense beliefs? This book defends a form of naturalism which preserves the autonomy of metaphysics – the part of philosophy that aims to uncover the fundamental features of reality - while also keeping science centre stage. The proposed methodological perspective allows one to seek the right equilibrium between science, metaphysics and common sense. This is illustrated via three case studies, which provide a clear discussion of key philosophical issues. (shrink)

1. Categories and the Scientific Turn of Metaphysics: The Notion of World-Fundamentality What are the fundamental inhabitants of the world? This question, as old as it is new, is about the fundamental structure of our world. Is our world a world of Aristotle's ordinary substances, Locke's physical substances, Husserl's wholes, Wittgenstein's facts, Sellars's processes, or Quine's sets? In order to distinguish the sort of metaphysical fundamentality at stake in this discussion from other possible types of fundamentality, I shall call it (...) from now on "world-fundamentality." In this article I want to make a proposal in the context of this metaphysical dispute. The proposal is the addition of a new criterion of world-fundamentality to the existing catalog of independence and simplicity, among some other prominent classical examples. I call this criterion "the materialist criterion of world-fundamentality" because it states that metaphysicians should not decide the question of whether our world is a world of facts rather than a world of sets or other categories without considering the explanatory power of such categories to account for the relation between "the manifest image" and "the scientific image," to use the words of Wilfrid Sellars.

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)
