A sequel to the author’s book /Frege’s Puzzle/ (1986).

Quine’s criterion of theoretical ontological commitment is subject to a variety of interpretations, all of which save one yield incorrect verdicts. Moreover, the interpretation that yields correct verdicts is not what Quine meant. Instead the intended criterion unfairly imputes ontological commitments to theories that lack those commitments and fails to impute commitments to theories that have them. Insofar as Quine’s criterion is interpreted so that it yields only correct verdicts, it is trivial and of questionable utility. Moreover, the correct criterion (...) invokes analyticity, a notion that Quine spent most of his life tirelessly combating. This yields a dilemma for Quinean philosophy: Either his criterion of ontological commitment is incorrect, or else Quine is committed to a traditional philosophical notion that he emphatically rejected as disreputable.

I defend the widely-held view that morally worthy action need not be motivated by a desire to promote rightness as such. Some have recently come to reject this view, arguing that desires for rightness as such are necessary for avoiding a certain kind of luck thought incompatible with morally worthy action. I show that those who defend desires for rightness as such on the basis of this argument misunderstand the relationship between moral worth and the kind of luck that their (...) argument employs. Consequently, the argument provides no reason to doubt the popular view that a desire for rightness as such is no part of virtue. I conclude by suggesting that a family of worries about merely accidentally right action presuppose one side of the recent debate about objectivism and perspectivism about moral rightness. (shrink)

The Counterfactual Comparative Account of Harm says that an event is overall harmful for someone if and only if it makes her worse off than she otherwise would have been. I defend this account from two common objections.

While it is tempting to suppose that an act has moral worth just when and because it is motivated by sufficient moral reasons, philosophers have, largely, come to doubt this analysis. Doubt is rooted in two claims. The first is that some facts can motivate a given act in multiple ways, not all of which are consistent with moral worth. The second is the orthodox view that normative reasons are facts. I defend the tempting analysis by proposing and defending a (...) heterodox account of both normative and motivating reasons that is inspired by Donald Davidson’s primary reasons. We should adopt the heterodox view, I argue, because it addresses an overlooked but fatal defect in the orthodox conception of reasons, of which challenges to the tempting analysis are a special case.

Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

Toward a theory of n-tuples of individuals and concepts as surrogates for Russellian singular propositions and singular concepts. Alonzo Church proposed a powerful and elegant theory of sequences of functions and their arguments as singular-concept surrogates. Church’s account accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill paradox is misguided. Russell-Myhill is not a problem specifically for Alternative (0). Rather (...) it is a disproof of unrestricted concept comprehension. Unrestricted comprehension is also inconsistent with facts about sets of properties. It is demonstrated furthermore that the principal rival conception of propositions, as classes of possible worlds, is subject to a fatal philosophical collapse: It follows on that conception, given that each of us is fallible, that everyone believes everything. Although it is far superior to its principal rival conception, Church’s proposed theory is vulnerable under (0) to a version of Russell’s notorious Gray’s /Elegy/ objection. Some amendments to Church’s proposal are proffered that address Russell’s objection, including an amendment first proposed in the present author’s /Frege’s Puzzle/ (1986). Church’s response (personal correspondence) is considered. (shrink)

We offer an original argument for the existence of universal fictions—that is, fictions within which every possible proposition is true. Specifically, we detail a trio of such fictions, along with an easy-to-follow recipe for generating more. After exploring several consequences and dismissing some objections, we conclude that fiction, unlike reality, is unlimited when it comes to truth.

Some prominent scientists and philosophers have stated openly that moral and political considerations should influence whether we accept or promulgate scientific theories. This widespread view has significantly influenced the development, and public perception, of intelligence research. Theories related to group differences in intelligence are often rejected a priori on explicitly moral grounds. Thus the idea, frequently expressed by commentators on science, that science is “self-correcting”—that hypotheses are simply abandoned when they are undermined by empirical evidence—may not be correct in all (...) contexts. In this paper, documentation spanning from the early 1970s to the present is collected, which reveals the influence of scientists’ moral and political commitments on the study of intelligence. It is suggested that misrepresenting findings in science to achieve desirable social goals will ultimately harm both science and society. (shrink)

In this candid autobiographical essay, Nathan Salmon recounts and assesses the impact of various philosophers and events on his philosophical development.

The Substituted Judgment Standard for surrogate decision-making dictates that a surrogate, when making medical decisions on behalf of an incapacitated patient, ought to make the decision that the patient would have made if the patient had decisional capacity. Despite its intuitive appeal, however, SJS has been the target of a variety of criticisms. Most objections to SJS appeal to epistemic difficulties involved in determining what a patient would have decided in a given case. In this article, I offer an alternative (...) standard for surrogate decision-making that avoids these difficulties. I then offer an account of its theoretical underpinnings which shows that it preserves the central moral justification for SJS, namely, respect for patient autonomy. (shrink)

The past decade and a half has seen an absolute explosion of literature discussing the structure of reality. One particular focus here has been on the fundamental. However, while there has been extensive discussion, numerous fundamental questions about fundamentality have not been touched upon. In this chapter, I focus on one such lacuna about the modal strength of fundamentality. More specifically, I am interested in exploring the contingent fundamentality thesis - that is, the idea that the fundamentalia are only contingently (...) fundamental (or, in property-terms, that the property of being fundamental is not a (weakly) necessary property). And while I think this thesis is plausible – indeed, I show here that it lurks in the unexamined shadows/assumptions of some fairly prominent positions – as far as I can tell, nothing has been said either for or against it. Here, I hope to fix this by giving the thesis a proper airing. In this way, this chapter represents a first-pass at exploring not only the modal status of fundamentality, but also offers a starting point for examining broader issues about the relationship between fundamentality and modality.

Georgalis claimed that when Frege wrote ‘Über Sinn und Bedeutung’ Frege thought that the indirect [ungerade] sense of an expression was identical to its normal [gewöhnlich] sense (Georgalis 2022: e.g. 4, 5, 13). In this paper, I present five arguments for the falsity of Georgalis’ claim which are based on three pieces of apparent counterevidence: a passage from Frege’s letter to Russell dated 28.12.1902; a passage from Frege’s letter to Russell dated 20.10.1902; and a passage from ‘Über Sinn und Bedeutung’. (...) I outline possible counter-arguments and responses. (shrink)

In this paper, I present a challenge for Michael McKenna’s conversational theory of moral responsibility. On his view, to be a responsible agent is to be able to engage in a type of moral conversation. I argue that individuals with autism spectrum disorder present a considerable problem for the conversational theory because empirical evidence on the disorder seems to suggest that there are individuals in the world who meet all of the conditions for responsible agency that the theory lays out (...) but who are nevertheless not responsible agents. Attending to the moral psychology of such individuals will, I think, help shed light on an important gap in the conversational theory. (shrink)

Music and language are universal human abilities with many apparent similarities relating to their acoustics, structure, and frequent use in social situations. We might therefore expect them to be understood and processed similarly, and indeed an emerging body of research suggests that this is the case. But the focus has historically been on the individual, looking at the passive listener or the isolated speaker or performer, even though social interaction is the primary site of use for both domains. Nonetheless, an (...) important goal of emerging research is to compare music and language in terms of acoustics and structure, social interaction, and functional origins to develop parallel accounts across the two domains. Indeed, a central aim of both of evolutionary musicology and language evolution research is to understand the adaptive significance or functional origin of human music and language. An influential proposal to emerge in recent years has been referred to as the social bonding hypothesis. Here, within a comparative approach to animal communication systems, I review empirical studies in support of the social bonding hypothesis in humans, non-human primates, songbirds, and various other mammals. In support of this hypothesis, I review six research fields: (i) the functional origins of music; (ii) the functional origins of language; (iii) mechanisms of social synchrony for human social bonding; (iv) language and social bonding in humans; (v) music and social bonding in humans; and (vi) pitch, tone and emotional expression in human speech and music. I conclude that the comparative study of complex vocalizations and behaviors in various extant species can provide important insights into the adaptive function(s) of these traits in these species, as well as offer evidence-based speculations for the existence of “musilanguage” in our primate ancestors, and thus inform our understanding of the biology and evolution of human music and language.

A distinction is drawn among predicates, open sentences (or open formulas), and general terms, including general-term phrases. Attaching a copula, perhaps together with an article, to a general term yields a predicate. Predicates can also be obtained through lambda-abstraction on an open sentence. The issue of designation and semantic content for each type of general expression is investigated. It is argued that the designatum of a general term is a universal, e.g., a kind, whereas the designatum of a predicate is (...) a class (or its characteristic function) and the designatum of an open sentence is a truth-value. Predicates and open sentences are therefore typically non-rigid designators. It is argued further that certain general terms, including phrases, are invariably rigid designators, whereas certain others (general definite descriptions) are typically non-rigid. Suitable semantic contents for predicates, open sentences, and general terms are proposed. Consequences for the thesis of compositionality are drawn. (shrink)

Many philosophers think that, when someone deserves something, it’s intrinsically good that she get it or there’s a non-instrumental reason to give it to her. Retributivists who try to justify punishment by appealing to claims about what people deserve typically assume this view or views that entail it. In this paper, I present evidence that many people have intuitions that are inconsistent with this view. And I argue that this poses a serious challenge to retributivist arguments that appeal to desert.

Inflicting harm is generally preferable to inflicting death. If you must choose between the two, you should generally choose to harm. But prenatal harm seems different. If a mother must choose between harming her fetus or aborting it, she may choose either, at least in many cases. So it seems that prenatal harm is particularly objectionable, sometimes on a par with death. This paper offers an explanation of why prenatal harm seems particularly objectionable by drawing an analogy to the all-or-nothing (...) problem. It then argues that this analogy offers independent support for the ‘voluntarist’ view that at least some parental role obligations are grounded in the choice to be a parent. (shrink)

This paper continues a debate about the following claim: an agent punishes someone only if she aims to harm him. In a series of papers, Bill Wringe argues that this claim is false, I criticize his arguments, and he replies. Here, I argue that his reply fails.

Many philosophers think that an agent punishes a subject only if the agent aims to harm the subject. Bill Wringe has recently argued against this claim. I show that his arguments fail.

Kit Fine has replied to my criticism of a technical objection he had given to the version of Millianism that I advocate. Fine evidently objects to my use of classical existential instantiation in an object-theoretic rendering of his meta-proof. Fine’s reply appears to involve both an egregious misreading of my criticism and a significant logical error. I argue that my rendering is unimpeachable, that the issue over my use of classical EI is a red herring, and that Fine’s original argument (...) commits the straw-man fallacy. I argue further that contrary to Fine’s gratuitous attribution, what Kripke’s Pierre lacks and a typical bilingual has is not knowledge of a “manifest-making” premise, but the capacity to recognize London when it is differently designated. Fine’s argument refutes a preposterous theory no one advocates while leaving standard Millianism unscathed. The failure of his argument threatens to render Fine’s central notion of “coordination” redundant or empty. (shrink)

When the environment in which an organism lives deviates in some essential way from that to which it is adapted, this is described as “evolutionary mismatch,” or “evolutionary novelty.” The notion of mismatch plays an important role, explicitly or implicitly, in evolution-informed cognitive psychology, clinical psychology, and medicine. The evolutionary novelty of our contemporary environment is thought to have significant implications for our health and well-being. However, scientists have generally been working without a clear definition of mismatch. This paper defines (...) mismatch as deviations in the environment that render biological traits unable, or impaired in their ability, to produce their selected effects. The machinery developed by Millikan in connection with her account of proper function, and with her related teleosemantic account of representation, is used to identify four major types, and several subtypes, of evolutionary mismatch. While the taxonomy offered here does not in itself resolve any scientific debates, the hope is that it can be used to better formulate empirical hypotheses concerning the effects of mismatch. To illustrate, it is used to show that the controversial hypothesis that general intelligence evolved as an adaptation to handle evolutionary novelty can, contra some critics, be formulated in a conceptually coherent way.

In this paper I argue that Locke takes sensitive knowledge (i.e. knowledge from sensation) to be genuine knowledge that material objects exist. Samuel Rickless has recently argued that, for Locke, sensitive knowledge is merely an “assurance”, or a highly probable judgment that falls short of certainty. In reply, I show that Locke sometimes uses “assurance” to describe certain knowledge, and so the use of the term “assurance” to describe sensitive knowledge does not entail that it is less than certain. Further, (...) I show that sensitive knowledge includes the perception of a relation between ideas, and thus it satisfies Locke’s definition of knowledge. He also repeatedly claims that sensitive knowledge is certain. So, despite recent challenges to this interpretation raised in the secondary literature, Locke really does take sensitive knowledge to be certain knowledge. (shrink)

The dogma that the propositional logic of metaphysical modality is S5 is rebutted. The author exposes fallacies in standard arguments supporting S5, arguing that propositional metaphysical modal logic is weaker even than both S4 and B, and is instead the minimal and weak metaphysical-modal logic T.

This article offers an interpretation of a controversial aspect of Frege’s The Foundations of Arithmetic, the so-called Julius Caesar problem. Frege raises the Caesar problem against proposed purely logical definitions for ‘0’, ‘successor’, and ‘number’, and also against a proposed definition for ‘direction’ as applied to lines in geometry. Dummett and other interpreters have seen in Frege’s criticism a demanding requirement on such definitions, often put by saying that such definitions must provide a criterion of identity of a certain kind. (...) These interpretations are criticized and an alternative interpretation is defended. The Caesar problem is that the proposed definitions fail to well-define ‘number’ and ‘direction’. That is, the proposed definitions, even when taken together with the extra-definitional facts, fail to fix unique semantic extensions for ‘number’ and ‘direction’, and thereby fail to fix unique truth-values for sentences like ‘Caesar is a number’ and ‘England is a direction’. A minor modification of the criticized definitions well-defines ‘0’, ‘successor’ and ‘number’, thereby avoiding the Caesar problem as Frege understands it, but without providing any criterion of number identity in the usual sense.

In recent years there has been an explosion of philosophical work on blame. Much of this work has focused on explicating the nature of blame or on examining the norms that govern it, and the primary motivation for theorizing about blame seems to derive from blame’s tight connection to responsibility. However, very little philosophical attention has been given to praise and its attendant practices. In this paper, I identify three possible explanations for this lack of attention. My goal is to (...) show that each of these lines of thought is mistaken and to argue that praise is deserving of careful, independent analysis by philosophers interested in theorizing about responsibility.

A Russellian notion of what it is for a proposition to be “directly about” something in particular is defined. Various strong and weak, and mediate and immediate, Russellian notions of general aboutness are then defined in terms of Russellian direct aboutness. In particular, a proposition is about something iff the proposition is either directly, or strongly indirectly, about that thing. A competing Russellian account, due to Kaplan, is criticized through a distinction between knowledge by description and denoting by description. The (...) epistemological significance of Russellian aboutness is assessed. A Russellian substitute for de re propositional attitude is considered. (shrink)

While intimately familiar, gender eludes theorizing. We argue that well-known challenges to gender’s analysis originate in a subtle ambiguity: questions about gender sometimes express questions about gender categories themselves (e.g., womanhood, manhood, and so on), while at other times expressing questions about what makes someone a member of these categories. Distinguishing these questions accentuates gender’s connections to morality, making a novel “antirealist” view of gender, or as we call it, “unrealist” view, especially natural. Gender’s relations to identity, sex, and social (...) position are illuminated along the way. Taking cues from both historical and contemporary debates in metaethics about the roles that attitudes can play in metaphysical and semantic analysis, we introduce and begin developing a comprehensive non-ameliorative framework for explicating gender’s nature and our thought and talk about it. In a slogan, on the view we defend, you belong to the gender category to which you intrinsically desire to belong. (shrink)

There’s a long but relatively neglected tradition of attempting to explain why many researchers working on the nature of phenomenal consciousness think that it’s hard to explain.1 David Chalmers argues that this “meta-problem of consciousness” merits more attention than it has received. He also argues against several existing explanations of why we find consciousness hard to explain. Like Chalmers, we agree that the meta-problem is worthy of more attention. Contra Chalmers, however, we argue that there’s an existing explanation that is (...) more promising than his objections suggest. We argue that researchers find phenomenal consciousness hard to explain because phenomenal concepts are complex demonstratives that encode the impossibility of explaining consciousness as one of their application conditions.
