We argue that Horgan's program for nominalizing science fails, because its translation of quantitative statements destroys the inferential structures of explanations, predictions and retrodictions of nonquantitative scientific facts.

Recently, Kit Fine's (1994) view that modal truths aretrue in virtue of,grounded in, orexplained byessentialist truths has been under attack. In what follows we offer two responses to the wave of criticism against his view. While the first response is pretty straightforward, the second is based on the distinction between, what we call,Reductive Finean EssentialismandNon-Reductive Finean Essentialism. Engaging the work of Bob Hale onNon-Reductive Finean Essentialism, we aim to show that the arguments against Fine's view are unconvincing, while we (...) acknowledge the presence of a deep standoff between the two views.

From the philosophy of mind and language, through physics and mathematics, to the philosophy of the human sciences, morality and religion, there is almost no area of philosophy to which Hilary Putnam has not made highly original and influential contributions. This wide-ranging collection of papers provides a critical assessment and exploration of Putnam's Seminal Work. Written by Philosophers themselves well known for their work in the field, each essay bears witness to the continuing influence and importance of Putnam's thought. Putnam's (...) reply constitutes an extensive new essay which clarifies, and develops further, central themes in his philosophy. This volume includes papers by Simon Blackburn, George Boolos, Michael Hallett, Michael Redhead, Thomas Ricketts, David Wiggins and Crispin Wright. (shrink)

Michael Dummett mounts, in Frege: Philosophy of Mathematics, a concerted attack on the attempt, led by Crispin Wright, to salvage defensible versions of Frege's platonism and logicism in which Frege's criterion of numerical identity plays a leading role. I discern four main strands in this attack—that Wright's solution to the Caesar problem fails; that explaining number words contextually cannot justify treating them as enjoying robust reference; that Wright has no effective counter to ontological reductionism; and that the attempt is (...) vitiated by the unavoidable impredicativity of its leading principle—and argue that none of them succeeds.

This review admires Michael Marder’s inquiry as a parallel for which biosemiotics can find points of conceptual resonance, even as methodological differences remain. By looking at the dump of ungrounded semiosis – the semiotics of dislocating referents from objects, and its effects – we can better do the work of applying biosemiotics not just towards the wonders of living relations, but also to the manifold ways in which industrial civilization is haphazardly yet systematically destroying the possibility for spontaneous yet (...) contextualized semiogenesis. Biosemiotics has much to gain by understanding the ways, gross and subtle, in which Anthropocenic hubris undercuts our own ability to make sense of the world, doubling down on overconfidence at the expense of meaning-making.

What is wrong with abstraction’, Michael Potter and Peter Sullivan explain a further objection to the abstractionist programme in the foundations of mathematics which they first presented in their ‘Hale on Caesar’ and which they believe our discussion in The Reason's Proper Study misunderstood. The aims of the present note are: To get the character of this objection into sharper focus; To explore further certain of the assumptions—primarily, about reference-fixing in mathematics, about certain putative limitations of abstractionist set (...) theory, and about the effects of impredicativity in abstraction principles—which underlie it; and To advance the debate of the issues thereby raised.

This chapter begins with an examination of Michael Dummett's influential treatment of the issues, which couples an attempt to identify a common form exemplified by a large, if not exhaustive, range of R/AR disputes with important arguments against a realist position about meaning which ‐ if they are sound. It also examines Dummett's diagnosis of what is at stake in those disputes is correct ‐ promise to resolve the issue in the anti‐realist's favor, not only in the theory of (...) meaning itself, but across the board. The chapter surveys the principal negative arguments, advanced by Dummett and others, for semantic anti‐realism. It explains the arguments on R/AR disputes more generally, and reviews doubts about the adequacy of Dummett's general conception of their common form. It reviews other ways in which the anti‐realist case may be prosecuted. It concludes with a brief examination of the new perspective on R/AR disputes advocated in recent work by Wright. (shrink)

I point out that conceptions of particles as mathematical, or quasi mathematical, entities have a longer history than Resnik notices. I argue that Resnik's attack on the distinction between mathematical and physical entities is not deep enough. The crucial problem for this distinction finds its locus in the numerical indeterminancy of elementary particles. This problem, traced by Heisenberg, emerges from the discovery of antimatter.

A follow-up, showing why Bob Hale's revision of his notion of weak sense is still inadequate.

A very influential idea in the epistemology of modality is that we acquire knowledge of metaphysical modality through knowledge of essence. As a consequence, the epistemology of essence becomes crucial in the attempt to answer the question of how we come to know modal propositions. In this paper I investigate Lowe’s and Hale’s approach to the epistemology of essence and argue that both of them remain in a crucial, structural sense incomplete. Systematizing this criticism against Lowe and Hale, (...) I then break down desiderata of what I call a structurally complete picture of the epistemology of essence. Finally, I discuss Husserl’s epistemology of essence and defend it against a notorious objection. However, Husserl’s approach also seems to remain incomplete, due to its appeal to imagination, which operates on the basis of background assumptions that are themselves in need of justification. I indicate, however, that a Husserlian theory of intuitive awareness of universals might supply us with (direct) justification of these background assumptions and, hence, that we might be able to paint a structurally complete picture of the epistemology of essence with Husserlian means.

Fine, Lowe and Hale accept the view that necessity is to be explained by essences: Necessarily p iff, and because, there is some x whose essence ensures that p. Hale, however, believes that this strategy is not universally applicable; he argues that the necessity of essentialist truths cannot itself be explained by once again appealing to essentialist truths. As a consequence, Hale holds that there are basic necessities that cannot be explained. Thus, Hale style essentialism falls (...) short of what Wilsch calls the explanation-challenge (EC) for the metaphysics of necessity. Without endorsing the EC, I argue that Hale’s argument for basic, unexplained necessities fails due to a misunderstanding of the structure of essentialist explanations. Getting clear about the structure of essentialist explanations of necessity leads to a re-evaluation of crucial circularity- and regress-arguments that have been discussed in the debate about essentialism.

Explains why Bob Hale's proposed notion of weak sense cannot explain the analyticity of Hume's principle as he claims. Argues that no other notion of the sort Hale wants could do the job either.

Crispin Wright and Bob Hale have defended the strategy of defining the natural numbers contextually against the objection which led Frege himself to reject it, namely the so-called ‘Julius Caesar problem’. To do this they have formulated principles (called sortal inclusion principles) designed to ensure that numbers are distinct from any objects, such as persons, a proper grasp of which could not be afforded by the contextual definition. We discuss whether either Hale or Wright has provided independent motivation (...) for a defensible version of the sortal inclusion principle and whether they have succeeded in showing that numbers are just what the contextual definition says they are.

We correct a misunderstanding by Hale and Wright of an objection we raised earlier to their abstractionist programme for rehabilitating logicism in the foundations of mathematics.

Pluralism, according to Michael P. Lynch, is the thesis that there are or can be more than one true story of the world; there can be incompatible but equally acceptable accounts of some subject matter.

In lieu of an abstract, here is a brief excerpt of the content:Unibilitas: The Key to Bonaventure’s Understanding of Human NatureThomas M. Osborne Jr.Historians of medieval philosophy have sometimes described St. Bonaventure’s anthropology as dualist or Augustinian. The conventional story runs that the conservative Bonaventure was afraid of contemporary attempts to describe the rational soul as the substantial form of the corporeal body.1 Bonaventure’s relationship to two intellectual trends lends some support to this theory. First, Bonaventure, following Avicebron and Alexander (...) of Hales, believed in universal hylomorphism, holding that all substances, even the angels and human souls separated from the body, are comprised of matter and form.2 If the human soul apart from the body has its own matter, then in what [End Page 227] sense can the soul be the substantial form of corporeal matter? Second, followers of Bonaventure pointed to this difficulty when they held that the body has its own forma corporeitatis.3 It is not surprising that some historians have regarded Bonaventure as a strong dualist. If the soul is a substance apart from the body, then how can it be one substance with the body? Unibilitasis Bonaventure’s answer to this problem.Bonaventure himself is thoroughly aware that he might seem to regard the soul as a complete substance by itself when he describes it as a composition of form with spiritual matter. If the soul is a composition of form and matter, then it is a hoc aliquid and complete in itself. The soul united with the body could not combine into a third substance.4 I will argue that for Bonaventure unibility is this ability of the soul and body to be united as one substance.In the thirteenth century, unibility describes the ability of two different substances or dispositions to become one supposit.5 For example, Bonaventure and Thomas Aquinas use unibility to describe how Christ’s human nature and his divine nature can be one person. Moreover, John of Rupella, Thomas Aquinas, and Bonaventure use unibility to describe how the soul and the body form one substance. Most historians, like E. Gilson and E. Weber, have generally described unibility as the attempt to show how one human person can have both a substance which is spiritual and a different substance which is corporeal.6 Unibility is for them a concept which precedes the Thomistic discovery of the soul as the substantial form of the body. If this interpretation [End Page 228] were correct, then it would be difficult to see how Thomas Aquinas could retain the term. In fact, unibility has a variety of uses which depend upon the context of its appearance and the thought of the one who uses it.The unibility of the soul plays a far greater role in the thought of Bonaventure than it does in the thought of Thomas Aquinas. Bonaventure describes unibility as the specific difference between the angels and humans. Unlike Thomas, Bonaventure thinks that humans, like angels, have both a substantial form and spiritual matter. A human being differs from an angel in that a human’s form can also be the substantial form of a body. Since unibility lies at the heart of Bonaventure’s anthropology, it seems strange that it has not been more thoroughly examined and discussed.The four main sections of this paper roughly correspond to the different contexts in which Bonaventure uses unibility to describe a property of the human soul. The first section shows that unibility is the specific difference that distinguishes humans from angels in the genus of intellectual substances. Second, this difference between humans and angels will be elaborated to show how human souls, unlike angels, are not only movers of bodies, but also perfections of their own particular body. The third section argues that since the soul is the perfection of the body, it is also the one substantial form of the body. The fourth section touches on Bonaventure’s discussion of personhood to show that the human soul when separated from the body is not a person because it is not a fully individual substance. Since an angel is not unitable to a human body, it is unlike a human soul in that it does not need... (shrink)

Bob Hale presents a broadly Fregean approach to metaphysics, according to which ontology and modality are mutually dependent upon one another. He argues that facts about what kinds of things exist depend on facts about what is possible. Modal facts are fundamental, and have their basis in the essences of things--not in meanings or concepts.

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

Possibility offers a new analysis of the metaphysical concepts of possibility and necessity, one that does not rely on any sort of "possible worlds." The analysis proceeds from an account of the notion of a physical object and from the positing of properties and relations. It is motivated by considerations about how we actually speak of and think of objects. Michael Jubien discusses several closely related topics, including different purported varieties of possible worlds, the doctrine of "essentialism," natural kind (...) terms and alleged examples of necessity a posteriori. The book also offers a new theory of the functioning of proper names, both actual and fictional, and the discussion of natural kind terms and necessity a posteriori depends in part on this theory.

When philosophers discuss the possibility of machines making scientific discoveries, they typically focus on discoveries in physics, biology, chemistry and mathematics. Observing the rapid increase of computer-use in science, however, it becomes natural to ask whether there are any scientific domains out of reach for machine discovery. For example, could machines also make discoveries in qualitative social science? Is there something about humans that makes us uniquely suited to studying humans? Is there something about machines that would bar them from (...) such activity? A close look at the methodology of interpretive social science reveals several abilities necessary to make a social scientific discovery, and one capacity necessary to possess any of them is imagination. For machines to make discoveries in social science, therefore, they must possess imagination algorithms. (shrink)

Here, Bob Hale and Crispin Wright assemble the key writings that lead to their distinctive neo-Fregean approach to the philosophy of mathematics. In addition to fourteen previously published papers, the volume features a new paper on the Julius Caesar problem; a substantial new introduction mapping out the program and the contributions made to it by the various papers; a section explaining which issues most require further attention; and bibliographies of references and further useful sources. It will be recognized as (...) the most powerful presentation yet of a neo-Fregean program. (shrink)

On the neo-Fregean approach to the foundations of mathematics, elementary arithmetic is analytic in the sense that the addition of a principle wliich may be held to IMJ explanatory of the concept of cardinal number to a suitable second-order logical basis suffices for the derivation of its basic laws.

In this paper, I assume the correctness of the neo-Fregean position on elementary aritlunetic and seek to (...) explain one way in which it may be extended to encompass the theory of real numbers, introducing the reals, by means of suitable further abstraction principles, as ratios of quantities.

For years, many people have believedthat the only reasonable way to approach a problem of environmental concern is to evaluate the eventuating state of affairs. Since environmental matters are primarily about states of affairs, these ‘consequentialist’ approaches appear to make sense. More recently, however, others have looked to different branches of philosophy for guidance. These non- or anti-consequentialist theorists typically fall into two camps: act-oriented camps and character-oriented camps. This chapter aims to defend nonconsequentialist act-oriented ethics, and in particular, a (...) deontological justificatory liberalism, as at least one plausible route forward for environmental ethics. It does so by suggesting that more traditional consequentialist approaches to environmental problems are subject to potentially devastating criticisms that can more adequately be handled by some deontological approaches.
