Abstract: By carefully examining one of the most famous thought experiments in the history of science – that by which Galileo is said to have refuted the Aristotelian theory that heavier bodies fall faster than lighter ones – I attempt to show that thought experiments play a distinctive role in scientific inquiry. Reasoning about particular entities within the context of an imaginary scenario can lead to rationally justified concluusions that – given the same initial information – would not be rationally justifiable on the basis of a straightforward argument.
What are groups?
Abstract: In this paper I argue for a view of groups, things like teams, committees, clubs and courts. I begin by examining features all groups seem to share. I formulate a list of six features of groups that serve as criteria any adequate theory of groups must capture. Next, I examine four of the most prominent views of groups currently on offer – that groups are non-singular pluralities, fusions, aggregates and sets. I argue that each fails to capture one or more of the criteria. Last, I develop a view of groups as realizations of structures. The view has two components. First, groups are entities with structure. Second, since groups are concreta, they exist only when a group structure is realized. A structure is realized when each of its functionally defined nodes or places are occupied. I show how such a view captures the six criteria for groups, which no other view of groups adequately does, while offering a substantive answer to the question, ‘What are groups?’
Why Restore Works of Art?
Summary: Saito examines arguments concerning why artworks should be restored, which are couched in terms of a debate between “purist” and “integral/conservator” restoration. Purists believe artworks should only be cleaned, emphasizing the integrity of the material object, whereas integral restorationists are open to adding material to the work, emphasizing the integrity of the original aesthetic experience. Rather than embracing a particular side in this debate, Saito’s discussion reveals how cultural/historical considerations can be as important to the debate over restoration as aesthetic considerations.
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.
Persons and Personal Identity
Publisher’s note: As persons, we are importantly different from all other creatures in the universe. But in what, exactly, does this difference consist? What kinds of entities are we, and what makes each of us the same person today that we were yesterday? Could we survive having all of our memories erased and replaced with false ones? What about if our bodies were destroyed and our brains were transplanted into android bodies, or if instead our minds were simply uploaded to computers?
In this engaging and accessible introduction to these important philosophical questions, Amy Kind brings together three different areas of research: the nature of personhood, theories of personal identity over time, and the constitution of self-identity. Surveying the key contemporary theories in the philosophical literature, Kind analyzes and assesses their strengths and weaknesses. As she shows, our intuitions on these issues often pull us in different directions, making it difficult to develop an adequate general theory. Throughout her discussion, Kind seamlessly interweaves a vast array of up-to-date examples drawn from both real life and popular fiction, all of which greatly help to elucidate this central topic in metaphysics.
A perfect text for readers coming to these issues for the first time, Persons and Personal Identity engages with some of the deepest and most important questions about human nature and our place in the world, making it a vital resource for students and researchers alike.
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.
The Narrative Self
Abstract: This article examines the narrative approach to self found in philosophy and related disciplines. The strongest versions of the narrative approach hold that both a person’s sense of self and a person’s life are narrative in structure, and this is called the hermeneutical narrative theory. This article provides a provisional picture of the content of the narrative approach and considers some important objections that have been raised to the narrative approach. It defends the view that the self constitutes itself in narrative and argues for something less than the hermeneutical view insofar as the narrative is less agency-oriented and without an overarching thematic unity.
Essentialism and the Necessity of the Laws of Nature
Abstract: In this paper the author discusses and evaluates different arguments for the view that the laws of nature are metaphysically necessary. She conclude that essentialist arguments from the nature of natural kinds fail to establish that essences are ontologically more basic than laws, and fail to offer an a priori argument for the necessity of all causal laws. Similar considerations carry across to the argument from the dispositionalist view of properties, which may end up placing unreasonable constraints on property identity across possible worlds. None of her arguments preclude the possibility that the laws may turn out to be metaphysically necessary after all, but she argues that this can only be established by a posteriori scientific investigation. She argues for what may seem to be a surprising conclusion: that a fundamental metaphysical question – the modal status of laws of nature – depends on empirical facts rather than purely on a priori reasoning.
Fundamental Properties and the Laws of Nature
Abstract: Fundamental properties and the laws of nature go hand in hand: mass and gravitation, charge and electromagnetism, spin and quantum mechanics. So, it is unsurprising that one’s account of fundamental properties affects one’s view of the laws of nature and vice versa. In this essay,the author surveys a variety of recent attempts to provide a joint account of the fundamental properties and the laws of nature. Many of these accounts are new and unexplored. Some of them posit surprising entities, such as counterfacts. Other accounts posit surprising laws of nature, such as instantaneous laws that constrain the initial configuration of particles. These exciting developments challenge our assumptions about our basic ontology and provide fertile ground for further exploration.
Intuition, Imagination, and Philosophical Methodology
Publisher’s Note: This volume consists of fourteen chapters that focus on a trio of interrelated themes. First: what are the powers and limits of appeals to intuition in supporting or refuting various sorts of claims? Second: what are the cognitive consequences of engaging with content that is represented as imaginary or otherwise unreal? Third: what are the implications of these issues for the methodology of philosophy more generally? These themes are explored in a variety of cases, including thought experiments in science and philosophy, early childhood pretense, self?deception, cognitive and emotional engagement with fiction, mental and motor imagery, automatic and habitual behavior, and social categorization.
