Philosophical theories often hinge on claims about what is necessary or possible. But what are possibilities and necessities, and how could we come to know about them? This book aims to help demystify the methodology of philosophy, by treating such claims not as attempted descriptions of strange facts or distant ‘possible worlds’, but rather as ways of expressing rules or norms.
Metaphysics as modeling: the handmaiden’s tale
Critics of contemporary metaphysics argue that it attempts to do the hard work of science from the ease of the armchair. Physics, not metaphysics, tells us about the fundamental facts of the world, and empirical psychology is best placed to reveal the content of our concepts about the world. Exploring and understanding the world through metaphysical reflection is obsolete. In this paper, I will show why this critique of metaphysics fails, arguing that metaphysical methods used to make claims about the world are similar to scientific methods used to make claims about the world, but that the subjects of metaphysics are not the subjects of science. Those who argue that metaphysics uses a problematic methodology to make claims about subjects better covered by natural science get the situation exactly the wrong way around: metaphysics has a distinctive subject matter, not a distinctive methodology. The questions metaphysicians address are different from those of scientists, but the methods employed to develop and select theories are similar. In the first section of the paper, I will describe the sort of subject matter that metaphysics tends to engage with. In the second section of the paper, I will show how metaphysical theories are classes of models and discuss the roles of experience, common sense and thought experiments in the construction and evaluation of such models. Finally, in the last section I will discuss the way these methodological points help us to understand the metaphysical project. Getting the right account of the metaphysical method allows us to better understand the relationship between science and metaphysics, to explain why doing metaphysics successfully involves having a range of different theories, to understand the role of thought experiments involving fictional worlds, and to situate metaphysical realism in a scientifically realist context.
The controversy over the existence of ordinary objects
Abstract: The basic philosophical controversy regarding ordinary objects is: Do tables and chairs, sticks and stones, exist? This paper aims to do two things: first, to explain why how this can be a controversy at all, and second, to explain why this controversy has arisen so late in the history of philosophy. Section 1 begins by discussing why the ‘obvious’ sensory evidence in favor of ordinary objects is not taken to be decisive. It goes on to review the standard arguments against the existence of ordinary objects – including those based on problems with causal redundancy, parsimony, co-location, sorites arguments, and the special composition question. Section 2 goes on to address what it is about the contemporary approach to metaphysics that invites and sustains this kind of controversy, and helps make evident why debates about ordinary objects lead so readily to debates in metametaphysics about the nature of metaphysics itself.
Research Problems and Methods in Metaphysics
Abstract: This article offers a guide to a key area on metaphysics and covers the fundamental questions asked in metaphysics – areas that have continued to attract interest historically as well as topics that have emerged more recently as active areas of research. It is especially focused on research methods and problems.
There is no special problem with metaphysics
Abstract: I argue for the claim in the title. Along the way, I also address an independently interesting question: what is metaphysics, anyway? I think that the typical characterizations of metaphysics are inadequate, that a better one is available, and that the better one helps explain why metaphysics is no more problematic than the rest of philosophy
On the Apparent Antagonism Between Feminist and Mainstream Metapysics
Abstract: The relationship between feminism and metaphysics has historically been strained. Metaphysics has until recently remained dismissive of feminist insights, and many feminist philosophers have been deeply skeptical about any value that metaphysics might have when thinking about advancing gender justice. Nevertheless, feminist philosophers have in recent years increasingly taken up explicitly metaphysical investigations. Such feminist investigations have expanded the scope of metaphysics in holding that metaphysical tools can help advance debates on topics outside of traditional metaphysical inquiry (e.g. the nature of gender, sex, or sexuality). Moreover, feminist philosophers typically bring new methodological insights to bear on traditional ways of doing philosophy. Feminist metaphysicians have also recently begun interrogating the methods of metaphysics and they have raised questions about what metaphysics as a discipline is in the business of doing. In discussing such methodological issues, Elizabeth Barnes has recently argued that some prevalent conceptions of metaphysics rule out feminist metaphysics from the start and render it impossible. This is bad news for self-proclaimed feminist metaphysicians in suggesting that they are mistaken about the metaphysical status of their work. With this worry in mind, the paper asks: how does feminist metaphysics fare relative to ‘mainstream’ metaphysics? More specifically, it explores how feminist and ‘mainstream’ debates intersect, on what grounds do they come apart (if at all), and whether feminist metaphysics qualifies as metaphysics ‘proper’.
Metaphysics
Introduction: It is not easy to say what metaphysics is. Ancient and Medieval philosophers might have said that metaphysics was, like chemistry or astrology, to be defined by its subject matter: metaphysics was the ‘science’ that studied ‘being as such’ or ‘the first causes of things’ or ‘things that do not change’. It is no longer possible to define metaphysics that way. First, a philosopher who denied the existence of those things that had once been seen as constituting the subject-matter of metaphysics – first causes or unchanging things – would now be considered to be making thereby a metaphysical assertion. Second, there are many philosophical problems that are now considered to be metaphysical problems (or at least partly metaphysical problems) that are in no way related to first causes or unchanging things – the problem of free will, for example, or the problem of the mental and the physical.
The first three sections of this entry examine a broad selection of problems considered to be metaphysical and discuss ways in which the purview of metaphysics has expanded over time. The central problems of metaphysics were significantly more unified in the Ancient and Medieval eras. Which raises a question – is there any common feature that unites the problems of contemporary metaphysics? The final two sections of the entry discuss some recent theories of the nature and methodology of metaphysics, including those that consider metaphysics as an impossible enterprise.
Science as a guide to Metaphysics?
Abstract: Analytic metaphysics is in resurgence; there is renewed and vigorous interest in topics such as time, causation, persistence, parthood and possible worlds. Those 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. But there is also a widespread suspicion that science cannot really contribute to metaphysics, and that scientific findings grossly underdetermine metaphysical claims. Can science guide metaphysics? The author links this question to the the choice between Radical Pessimism on the one hand and either Moderate Pessimism or Optimism on the other.
