Really statistical explanation is a hitherto neglected form of noncausal scientific explanation. Explanations in population biology that appeal to drift are RS explanations. An RS explanation supplies a kind of understanding that a causal explanation of the same result cannot supply. Roughly speaking, an RS explanation shows the result to be mere statistical fallout.

Lynne Baker's concept of a first-person perspective is not as clear and straightforward as it might seem at first glance. There is a discrepancy between her argumentation that we have first-person perspectives and some characteristics she takes first-person perspectives to have, namely, that the instances of this capacity necessarily persist through time and are indivisible and unduplicable. Moreover, these characteristics cause serious problems concerning personal identity.

Normative discourse frequently involves explanation. For example, we tell children that hitting is wrong because it hurts people. In a recent paper, Selim Berker argues that to account for this kind of explanation, expressivists need an account of normative grounding. Against this, I argue that expressivists should eschew grounding and stick to a more pragmatic picture of explanation, one that focuses on how we use explanatory speech acts to communicate information. I propose that the standard form of a normative explanation (...) is a generalizing explanation, one which shows a particular moral injunction to follow from a more general injunction. I use Marc Lange’s account of unifying explanations in mathematics as a model for the canonical form of a normative explanation, but also to establish that logical entailment can be explanatory, so long as premises entailing the conclusion answer appropriately to our interests. An additional upshot of the resulting view is that it paves the way for a purely metaphysical solution to the problem of creeping minimalism. Quasireal properties are those that, unlike real properties, stand outside of the metaphysical hierarchy of grounding relations. (shrink)

Many explanations in science make use of mathematics. But are there cases where the mathematical component of a scientific explanation is explanatory in its own right? This issue of mathematical explanations in science has been for the most part neglected. I argue that there are genuine mathematical explanations in science, and present in some detail an example of such an explanation, taken from evolutionary biology, involving periodical cicadas. I also indicate how the answer to my title question impacts on broader (...) issues in the philosophy of mathematics; in particular it may help platonists respond to a recent challenge by Joseph Melia concerning the force of the Indispensability Argument.

I examine some problems standing in the way of a successful `field interpretation' of quantum field theory. The most popular extant proposal depends on the Hilbert space of `wavefunctionals.' But since wavefunctional space is unitarily equivalent to many-particle Fock space, two of the most powerful arguments against particle interpretations also undermine this form of field interpretation.

My aim is twofold: first, to root out the metaphysical assumptions that generate the problem of mental causation and to show that they preclude its solution; second, to dissolve the problem of mental causation by motivating rejection of one of the metaphysical assumptions that give rise to it. There are three features of this metaphysical background picture that are important for our purposes. The first concerns the nature of reality: all reality depends on physical reality, where physical reality consists of (...) a network of events.1 The second concerns the nature of causation, and the third concerns the conception of behavior. I try to vindicate a robust idea of mental causation. (shrink)

The nature of antimatter is examined in the context of algebraic quantum field theory. It is shown that the notion of antimatter is more general than that of antiparticles. Properly speaking, then, antimatter is not matter made up of antiparticles—rather, antiparticles are particles made up of antimatter. We go on to discuss whether the notion of antimatter is itself completely general in quantum field theory. Does the matter–antimatter distinction apply to all field theoretic systems? The answer depends on which of (...) several possible criteria we should impose on the space of physical states. (shrink)

Explaining Attitudes develops a new account of propositional attitudes - practical realism.

A central goal of the scientific endeavor is to explain phenomena. Scientists often attempt to explain a phenomenon by way of representing it in some manner—such as with mathematical equations, models, or theory—which allows for an explanation of the phenomenon under investigation. However, in developing scientific representations, scientists typically deploy simplifications and idealizations. As a result, scientific representations provide only partial, and often distorted, accounts of the phenomenon in question. Philosophers of science have analyzed the nature and function of how (...) scientists construct representations, deploy idealizations, and provide explanations. As such, our aim in this special issue is to bring these three pillars of research into closer contact with the contributions to it focusing on three main themes. -/- The first set of papers, Alan Baker (2021) and Marc Lange (2021), address mathematical explanations in science. Baker (2021), a proponent of mathematical Platonism, examines its capacity to evade the critique that the so-called Enhanced Indispensability Argument is circular. Lange (2021) examines distinctively mathematical explanations, arguing that neither Platonism nor representationalism are successful paths, and instead argues in favor of Aristotelian realism. A second theme emerging from the papers in this special issue is the impact that various conceptualizations of idealization have on our abilities to offer scientific explanations, to pro- duce an analysis of what explanations are or should be, and to understand scientific representation. Peter Tan (2021) suggests amending inferentialist accounts of scientific representation to account for inconsistent idealizations. Michael Strevens (2021) advocates a view wherein the introduction of idealizations into a model is legitimate so long as it pertains to non-difference-making factors, arguing for a logical reading of the notion of difference-making. Natalia Carrillo and Tarja Knuuttila (2022) offer an alternative account to the idealization-as-distortion view, emphasizing instead the holistic nature of idealization. -/- Finally, contributions by Carrillo and Knuuttila (2022), Terzian (2021), Valente (2021), and Rodriguez (2021) illustrate how issues regarding idealization, representation, and explanation are applied to specific contexts and across various sciences. Carrillo and Knuuttila (2022) examine conceptions of idealization in the context of models of the nerve impulse. Giulia Terzian (2021) extends the discussion of idealizations to the context of generative linguistics. Giovanni Valente (2021) examines how idealizations and evaluations of accurate representation impact capacities to explain phenomena in the context of statistical thermodynamics. Quentin Rodriguez (2021) examines the role of idealizations and analogies in various strategies to explain critical phenomena. -/- In what follows, we offer a brief overview of important philosophical issues connected to representation, idealization, and explanation in science. We then provide short summaries of the eight papers in this special issue. (shrink)

One recent trend in the philosophy of mathematics has been to approach the central epistemological and metaphysical issues concerning mathematics from the perspective of the applications of mathematics to describing the world, especially within the context of empirical science. A second area of activity is where philosophy of mathematics intersects with foundational issues in mathematics, including debates over the choice of set-theoretic axioms, and over whether category theory, for example, may provide an alternative foundation for mathematics. My central claim is (...) that these latter issues are of direct relevance to philosophical arguments connected to the applicability of mathematics. In particular, the possibility of there being distinct alternative foundations for mathematics blocks the standard argument from the indispensable role of mathematics in science to the existence of specific mathematical objects.

Self-consciousness, many philosophers agree, is essential to being a person. There is not so much agreement, however, about how to understand what self-consciousness is. Philosophers in the field of cognitive science tend to write off self-consciousness as unproblematic. According to such philosophers, the real difficulty for the cognitive scientist is phenomenal consciousness--the fact that we have states that feel a certain way. If we had a grip on phenomenal consciousness, they think, self-consciousness could be easily handled by functionalist models. For (...) example, recently Ned Block commented. (shrink)

According to the Constitution View of persons, a human person is wholly constituted by (but not identical to) a human organism. This view does justice both to our similarities to other animals and to our uniqueness. As a proponent of the Constitution View, I defend the thesis that the coming-into-existence of a human person is not simply a matter of the coming-into-existence of an organism, even if that organism ultimately comes to constitute a person. Marshalling some support from developmental psychology, (...) I give a broadly materialistic account of the coming-into-existence of a human person. I argue for the metaphysical superiority of the Constitution View to Biological Animalism, Thomistic Animalism, and other forms of Substance Dualism. I conclude by discussing the single implication of the Constitution View for thinking about abortion. Footnotesa Thanks to Gareth Matthews and Catherine E. Rudder for comments.

Standard bioethics textbooks present the field to students and non-experts as a form of "applied ethics." This ahistoric and rationalistic presentation is similar to that used in philosophy of science textbooks until three decades ago. Thomas Kuhn famously critiqued this self-conception of the philosophy of science, persuading the field that it would become deeper, richer, and more philosophical, if it integrated the history of science, especially the history of scientific change, into its self-conception. This essay urges a similar reconceptualization for (...) bioethics, arguing that the analysis of moral change ought to be integral to bioethics (and to ethics generally). It proceeds by suggesting the sterility of the ahistoric, rationalist applied ethics model of bioethics embraced by standard bioethics textbooks. It also suggests the fecundity of alternative conceptions of the bioethics that focus on the history of successful and failed attempts to negotiate moral change, and the history of multifaceted relations between moral philosophy and practical ethics.

Metaphysics has enjoyed a vigorous revival in the last few decades. Even so, there has been little ontological interest in the things that we interact with everyday—trees, tables, other people.1 It is not that metaphysicians ignore ordinary things altogether. Indeed, they are happy to say that sentences like ‘The daffodils are out early this year’ or ‘My computer crashed again’ are true. But they take the truth of such sentences not to require that a full description of reality mention daffodils (...) or computers. Many metaphysicians now interpret the apparent variety of things in the world as variety only of concepts applied to things that are basically of the same sort—for example, sums of particles or of temporal parts of particles.

Throughout his illustrious career, Roderick Chisholm was concerned with the nature of persons. On his view, persons are what he called ‘entia per se.’ They exist per se, in their own right. I too have developed an account of persons—I call it the ‘Constitution View’—an account that is different in important ways from Chisholm’s. Here, however, I want to focus on a thesis that Chisholm and I agree on: that persons have ontological significance in virtue of being persons. Although I’ll (...) make the notion of ontological significance more precise later, the rough idea is that Fs (persons, or whatever) have ontological significance just in case a new F is a new thing and not just a change in some already-existing thing.

Artifacts are objects intentionally made to serve a given purpose; natural objects come into being without human intervention. I shall argue that this difference does not signal any ontological deficiency in artifacts qua artifacts. After sketching my view of artifacts as ordinary objects, I’ll argue that ways of demarcating genuine substances do not draw a line with artifacts on one side and natural objects on the other. Finally, I’ll suggest that philosophers have downgraded artifacts because they think of metaphysics as (...) resting on a distinction between what is “mind­independent” and what is “mind­ dependent.” I’ll challenge the use of any such distinction as a foundation for metaphysics.

In this paper I examine a strategy which aims to bypass the technicalities of the indispensability debate and to offer a direct route to nominalism. The starting-point for this alternative nominalist strategy is the claim that--according to the platonist picture--the existence of mathematical objects makes no difference to the concrete, physical world. My principal goal is to show that the 'Makes No Difference' (MND) Argument does not succeed in undermining platonism. The basic reason why not is that the makes-no-difference claim (...) which the argument is based on is problematic. Arguments both for and against this claim can be found in the literature; I examine three such arguments, uncovering flaws in each one. In the second half of the paper, I take a more direct approach and present an analysis of the counterfactual which underpins the makes-no-difference claim. What this analysis reveals is that indispensability considerations are in fact crucial to the proper evaluation of the MND Argument, contrary to the claims of its supporters. (shrink)

Suppose that one adopts a broadly Chomskyan perspective, in which there is a distinction between the language faculty and other cognitive faculties, including what Chomsky has recently called the “Conceptual-Intensional system”. Then there must in principle be at least three stages in this association that need to be understood. First, there is the nonlinguistic stage of conceptualizing a particular event.1 For example, while all of the participants in an event may be affected by the event in some way or another, (...) human cognizers typically focus on one or the other of those changes as being particularly salient or relevant to their interests. This participant is taken to be the “theme” or “patient” of the event, perhaps in some kind of nonlinguistic conceptual representation, such as the one developed by Jackendoff (1983, 1990b). Second, this conceptual/thematic representation is associated with a linguistic representation in which the entity seen as the patient of the event is represented as (say) an NP that is the direct object of the verb that expresses what kind of an event it was. This is the interface between language and the conceptual system. Finally, there is the possibility of adjusting this representation internally to the language system, by way of movements, chain formations, Case assignment processes, or whatever other purely syntactic processes there may be. For example, the NP that represents the theme and starts out as the direct object of the verb may become the subject if there is no other subject in the linguistic representation, either because there was no agent in the conceptual representation (as with an unaccusative verb), or because it was suppressed (as with a passive verb).

In ‘Wittgenstein on Language and Rules’, Professor N. Malcolm took us to task for misinterpreting Wittgenstein's arguments on the relationship between the concept of following a rule and the concept of community agreement on what counts as following a given rule. Not that we denied that there are any grammatical connections between these concepts. On the contrary, we emphasized that a rule and an act in accord with it make contact in language. Moreover we argued that agreement in judgments and (...) in definitions is indeed necessary for a shared language. But we denied that the concept of a language is so tightly interwoven with the concept of a community of speakers as to preclude its applicabilty to someone whose use of signs is not shared by others. Malcolm holds that ‘This is an unwitting reduction of Wittgenstein's originality. That human agreement is necessary for “shared” language is not so striking a thought as that it is essential for language simpliciter .’ Though less striking, we believe that it has the merit of being a true thought. We shall once more try to show both that it is correct, and that it is a correct account of Wittgenstein's arguments. (shrink)

Philosophy textbooks typically treat bioethics as a form of "applied ethics"-i.e., an attempt to apply a moral theory, like utilitarianism, to controversial ethical issues in biology and medicine. Historians, however, can find virtually no cases in which applied philosophical moral theory influenced ethical practice in biology or medicine. In light of the absence of historical evidence, the authors of this paper advance an alternative model of the historical relationship between philosophical ethics and medical ethics, the appropriation model. They offer two (...) historical case studies to illustrate the ways in which physicians have "appropriated" concepts and theory fragments from philosophers, and demonstrate how appropriated moral philosophy profoundly influenced the way medical morality was conceived and practiced.

I examine Leonhard Euler’s original solution to the Königsberg bridges problem. Euler’s solution can be interpreted as both an explanation within mathematics and a scientific explanation using mathematics. At the level of pure mathematics, Euler proposes three different solutions to the Königsberg problem. The differences between these solutions can be fruitfully explicated in terms of explanatory power. In the scientific version of the explanation, mathematics aids by representing the explanatorily salient causal structure of Königsberg. Based on this analysis, I defend (...) a version of the so-called “Transmission View” of scientific explanations using mathematics against objections by Alan Baker and Marc Lange, and I discuss Lange’s notion of “distinctively mathematical explanations” and Christopher Pincock’s notion of “abstract explanations”.

Social Externalism is the thesis that many of our thoughts are individuated in part by the linguistic and social practices of the thinker’s community. After defending Social Externalism and arguing for its broad application, I turn to the kind of defeasible first-person authority that we have over our own thoughts. Then, I present and refute an argument that uses first-person authority to disprove Social Externalism. Finally, I argue briefly that Social Externalism—far from being incompatible with first-person authority—provides a check on (...) first-personal pronouncements and thus saves first-person authority from being simply a matter of social convention and from collapsing into the subjectivity of “what seems right is right.”.

What is this thing called ‘Commonsense Psychology’? The first matter to settle is what the issue is here. By ‘commonsense psychology,’ I mean primarily the systems of describing, explaining and predicting human thought and action in terms of beliefs, desires, hopes, fears, expectations, intentions and other so-called propositional attitudes. Although commonsense psychology encompasses more than propositional attitudes--e.g., emotions, traits and abilities are also within its purview--belief-desire reasoning forms the core of commonsense psychology. Commonsense psychology is what we use to explain (...) intentional action as ordinarily described--e.g., Jack went to the store because he wanted some ice cream. Commonsense psychology also is used to explain mental states--e.g., Jill feared that she would be late because she thought that the meeting began at 4:00. Commonsense psychology is the province of everyone; we all use it all the time. (shrink)

Many physicalists are committed to an austere dichotomy: either beliefs, desires and intentions are scientifically respectable or attributions of such attitudes are all false. One physicalist, Daniel Dennett, offers a third alternative, which seems to permit a kind of instrumentalism concerning attitudes. I argue that Dennett's attempt to reconcile an instrumentalistic account of attributions of attitudes with a thoroughgoing physicalism founders on unresolvable conflicts between his official theory and his actual treatment of key concepts. As a result, instrumentalism concerning attitudes (...) is exposed as inadequate to be a genuine alternative to the physicalist's dichotomy. (shrink)
