It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

Many people want to hold that some theoretical virtues—simplicity, elegance, familiarity or others—are only pragmatic virtues. That is, these features do not give us any more reason to think a theory is true, or close to true, but they justify choosing one theoretical option over another because they are desirable for some other, practical purpose. Using pragmatic virtues in theory choice apparently brings with it a dilemma: if we are deciding what to accept on the basis of considerations that are (...) not truth-conducive, it looks like we should either refrain from believing what we accept, and adopt some sort of instrumentalist attitude to the theories we cherish; or alternatively, we stand charged with engaging in theoretical irrationality in our belief formation. This paper discusses the appropriate response to this dilemma. (shrink)

Philosophers have found postulating possible worlds to be very useful in a number of areas, including philosophy of language and mind, logic, and metaphysics. Impossible worlds are a natural extension to this use of possible worlds, and can help resolve a number of difficulties thrown up by possible‐worlds frameworks.

Impossible fictions are not just the creations of puzzle-seeking philosophers or artists experimenting with the limits of fiction. Impossibilities can be found in relatively mundane fiction as well. This article argues that the device of personification, especially of abstract entities such as death or duty, yields impossible fictions, arguing against a number of strategies that might be tried to show that these cases of personification do not yield impossibilities.

The Cambridge Descartes Lexicon is the definitive reference source on René Descartes, 'the father of modern philosophy' and arguably among the most important philosophers of all time. Examining the full range of Descartes' achievements and legacy, it includes 256 in-depth entries that explain key concepts relating to his thought. Cumulatively they uncover interpretative disputes, trace his influences, and explain how his work was received by critics and developed by followers. There are entries on topics such as certainty, cogito ergo sum, (...) doubt, dualism, free will, God, geometry, happiness, human being, knowledge, Meditations on First Philosophy, mind, passion, physics, and virtue, which are written by the largest and most distinguished team of Cartesian scholars ever assembled for a collaborative research project - 91 contributors from 12 countries.

Charles_ _Hartshorne characterizes this book as “an eloquent and insightful presentation of the claims of Buddhism to the attention of thoughtful people in this country, espe­cially those aware of the widely influential process philosophy and process theology of Whitehead.” Stressing Buddhism as opposed to West­ern philosophy, Jacobson concentrates on the theme of the self-corrective nature of Buddhism, ending with a strong emphasis on “self-surpassing Oneness.” Introducing the reader to the major perspectives of Buddhist philosophy, he notes that “the more fully (...) awakened we become to the moments that are the real event, the more we will recog­nize how much we need each other to enrich these _nows, _and the less tempted we will be to serve that abstract and false self.” Because everything on earth is a part of everything else, an organic whole, even the most enlightened self-interest is irrational and destructive. The rational person seeks to “infuse the life we live with the novel qualities of each _now.” _The rational person further struggles to “free himself from the one-sided, self-justifying cultural cocoons that have dwarfed and warped his awareness and crippled cross-cultural communica­tions,” according to Jacobson. Buddhism of­fers the only alternative to the enervated economic, political, diplomatic, and military measures presently used to “cope with un­derlying disaster.”. (shrink)

In the last few decades of the twentieth century there was a revolution in metaphysics: the intensional revolution. Many metaphysicians rejected the doctrine, associated with Quine and Davidson, that extensional analyses and theoretical resources were the only acceptable ones. Metaphysicians embraced tools like modal and counterfactual analyses, claims of modal and counterfactual dependence, and entities such as possible worlds and intensionally individuated properties and relations. The twenty-first century is seeing a hypterintensional revolution. Theoretical tools in common use carve more finely (...) than by necessary equivalence: two pieces of language can apply to the same entities across all possible worlds but not be equivalent; thoughts can be necessarily equivalent in truth value but not synonymous. This paper argues that hyperintensional resources are valuable in metaphysics outside theories of representation, and discusses some promising areas of hyperintensional metaphysics. (shrink)

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

In this paper, I motivate the view that quantitative parsimony is a theoretical virtue: that is, we should be concerned not only to minimize the number of kinds of entities postulated by our theories (i. e. maximize qualitative parsimony), but we should also minimize the number of entities postulated which fall under those kinds. In order to motivate this view, I consider two cases from the history of science: the postulation of the neutrino and the proposal of Avogadro's hypothesis. I (...) also consider two issues concerning how a principle of quantitative parsimony should be framed. (shrink)

Kenneth Inada calls this last book in Nolan Pliny Jacobson’s trilogy on Buddhist philosophy and process thought "not only timely, but urgent." "The message contained in the book," he notes, "should be released immediately." Seizo Ohe, Japan’s most distinguished philosopher of science, captures the essence of that message when he cites Jacobson’s understanding that Buddhism is "a new global cultural movement in which Japan and America are going to have a common world-historical mission—respectively as the eastern and western ends (...) of the eastern and western branches of human civilization." Jacobson convincingly demonstrates that Buddhism and the Western philosophies of Heraclitus and of modern thinkers such as Dewey, Whitehead, and Hartshorne have developed a reason truer to authentic experience than the reason so prevalent in traditionally dominant Western philosophy.

The surviving sources on the Stoic theory of division reveal that the Stoics, particularly Chrysippus, believed that bodies, places and times were such that all of their parts themselves had proper parts. That is, bodies, places and times were composed of gunk. This realisation helps solve some long-standing puzzles about the Stoic theory of mixture and the Stoic attitude to the present.

Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

Our ordinary moral practices not only suppose that some people ought to perform some actions, and that some outcomes are morally better or worse than others, but also that there are rights, duties, goodness, and other apparently abstract moral entities. What should we make of these entities, and the talk of these entities? It is not straighforward to account for these entities in other terms. On the other hand, this paper will argue that talk of such entities is not easily (...) eliminated from good moral theorising. Nor are the prospects for paraphrasing apparent talk about these entities into less committal terms very promising. We should either find a place in our ontology for these creatures of ethics, or explain how they can be employed as a convenient fiction. (shrink)

Despite its growing use over past decades, there has been relatively little public or scholarly discussion of life sentences that deny the possibility of parole. This essay outlines the labyrinthine legal and political developments that have rendered life imprisonment difficult to address—including the intertwined histories of the death penalty and civil death—and draws upon the life writing of those serving life to theorize a more distinct understanding of this punishment. Witnesses reveal how the possibility of life despite the impossibility of (...) parole punishes by subverting the goals of human growth and development. The potentiality of what can be done in the present grinds up against the futility of what could have been done and what could be done were release an option. Considered alongside the laws and court opinions and claims that characterize its convoluted development, these testimonies reveal this punishment’s role in the American imagination. Life without the possibility of parole reinforces and relies upon a vision that not simply some people are unable to change, but that anyone in a democracy—no matter their position—is some steps away from irretrievable exclusion. Permanent confinement denies a restorative vision of democracy: any effort to abolish or amend it must include the voices of those imprisoned. (shrink)

This book discusses a range of important issues in current philosophical work on the nature of possible worlds. Areas investigated include the theories of the nature of possible worlds, general questions about metaphysical analysis and questions about the direction of dependence between what is necessary or possible and what could be.

A lot of good philosophy is done in the armchair, but is nevertheless a posteriori. This paper clarifies and then defends that claim. Among the a posteriori activities done in the armchair are assembling and evaluating commonplaces; formulating theoretical alternatives; and integrating well-known past a posteriori discoveries. The activity that receives the most discussion, however, is the application of theoretical virtues to choose philosophical theories: the paper argues that much of this is properly seen as a posteriori.

In May 1999, David Lewis sent Timothy Williamson an intriguing letter about knowledge and vagueness. This paper has a brief discussion of Lewis on evidence, and a longer discussion of a distinctive theory of vagueness Lewis puts forward in this letter, one rather different from standard forms of supervaluationism. Lewis's theory enables him to provide distinctive responses to the challenges to supervaluationism famously offered in chapter 5 of Timothy Williamson's 1994 book Vagueness. However these responses bring out a number of (...) very surprising features of Lewis's own view. -/- The letter from Lewis itself is available on the blog of The Age of Metaphysical Revolution Project, University of Manchester.

Abstract There are at least eight good reasons practicing historians should concern themselves with counterfactual claims. Furthermore, four of these reasons do not even require that we are able to tell which historical counterfactuals are true and which are false. This paper defends the claim that these reasons to be concerned with counterfactuals are good ones, and discusses how each can contribute to the practice of history.

There’s an argument around from so-called “linguistic theories of vagueness”, plus some relatively uncontroversial considerations, to powerful metaphysical conclusions. David Lewis employs this argument to support the mereological principle of unrestricted composition, and Theodore Sider employs a similar argument not just for unrestricted composition but also for the doctrine of temporal parts. This sort of argument could be generalised, to produce a lot of other less palatable metaphysical conclusions. However, arguments to Lewis’s and Sider’s conclusions on the basis of considerations (...) about vagueness are uncompelling, even if we accept the crucial premises about vagueness. And a good thing too, since the generalised form of the argument would prove far too much. (shrink)

The cognition and information theoretic sciences have now been in existence for the better part of a century. In that time, their varied disciplines have undergone extensive maturation, honing their methods, constitutions, and evaluation techniques in the pursuit of academic rigor, while not losing sight of the practical influences that have served as their almost universal cornerstone. Meanwhile, this period has also been marked by increasing disparity and gradual distancing of the philosophical underpinnings upon which each field is founded, adding (...) strain to interdisciplinary collaborative efforts. This article presents an overview of select information-science-related cognition disciplines, and shows how the nascent Philosophy of Information can be adopted as a means of unifying these philosophical foundations in an empirically sound manner, without sacrificing general applicability. In addition, it demonstrates how PI is already rooted in the philosophies or epistemological views of several of the cognition disciplines, implicitly or otherwise. (shrink)

RULE or restricted utilitarianism is frequently propounded and just as frequently criticized in the literature. Its various refinements initially involve conceptual adjustments such as clarifying the logical relations between some stateable rule of utility and other moral rules or the specification of a criterion for ranking rules in case of conflict and so forth. It soon becomes clear, comparatively speaking, that a cluster of problems involving justice, personal rights and the denotation of ‘intrinsic good’ cannot be resolved without extending rule (...) utilitarianism as a theory of right conduct and justification; thus the origin of the appellation ‘extended’ rule utilitarianism. In this paper I shall: render an interpreted model of rule utilitarianism that possesses all the logical features of alternative interpretations. Describe a style of argument for extending rule utilitarianism to incorporate a rule of distribution. Such an extension preserves the consistency of rule utilitarianism. Describe a second style of argument for extending rule utilitarianism to incorporate a rule of distribution. Such an extension does not preserve the consistency of rule utilitarianism. (shrink)
