What makes a biological entity an individual? Jack Wilson shows that past philosophers have failed to explicate the conditions an entity must satisfy to be a living individual. He explores the reason for this failure and explains why we should limit ourselves to examples involving real organisms rather than thought experiments. This book explores and resolves paradoxes that arise when one applies past notions of individuality to biological examples beyond the conventional range and presents an analysis of identity and (...) persistence. The book's main purpose is to bring together two lines of research, theoretical biology and metaphysics, which have dealt with the same subject in isolation from one another. Wilson explains an alternative theory about biological individuality which solves problems which cannot be addressed by either field alone. He presents a more fine-grained vocabulary of individuation based on diverse kinds of living things, allowing him to clarify previously muddled disputes about individuality in biology. (shrink)

A natural suggestion and increasingly popular account of how to revise our logical beliefs treats revision of logic analogously to the revision of scientific theories. I investigate this approach and argue that simple applications of abductive methodology to logic result in revision-cycles, developing a detailed case study of an actual dispute with this property. This is problematic if we take abductive methodology to provide justification for revising our logical framework. I then generalize the case study, pointing to similarities with more (...) recent and popular heterodox logics such as naïve logics of truth. I use this discussion to motivate a constraint—logical partisanhood—on the uses of such methodology: roughly: both the proposed alternative and our actual background logic must be able to agree that moving to the alternative logic is no worse than staying put.

In this paper, I argue that all expressions for abstract objects are meaningless. My argument closely follows David Lewis’ argument against the intelligibility of certain theories of possible worlds, but modifies it in order to yield a general conclusion about language pertaining to abstract objects. If my Lewisian argument is sound, not only can we not know that abstract objects exist, we cannot even refer to or think about them. However, while the Lewisian argument strongly motivates nominalism, it also undermines (...) certain nominalist theories. (shrink)

Over the last few years there seems to have been a sharp increase in the number of books that want to spread the news that economics is, or at least can be, fun. This paper sets out to explain in what senses economics is supposed to be fun. In particular, the books in what I will call the economics-made-fun genre will be compared first with papers and books written by economists with the explicit intent of making fun of economics. Subsequently, (...) it will be examined whether or not it makes sense to accuse books in the economics-made-fun genre of economics imperialism, as some commentators have recently done. (shrink)

In this paper, I develop a "safety result" for applied mathematics. I show that whenever a theory in natural science entails some non-mathematical conclusion via an application of mathematics, there is a counterpart theory that carries no commitment to mathematical objects, entails the same conclusion, and the claims of which are true if the claims of the original theory are "correct": roughly, true given the assumption that mathematical objects exist. The framework used for proving the safety result has some advantages (...) over existing nominalistic accounts of applied mathematics. It also provides a nominalistic account of pure mathematics.

I investigate syntactic notions of theoretical equivalence between logical theories and a recent objection thereto. I show that this recent criticism of syntactic accounts, as extensionally inadequate, is unwarranted by developing an account which is plausibly extensionally adequate and more philosophically motivated. This is important for recent anti-exceptionalist treatments of logic since syntactic accounts require less theoretical baggage than semantic accounts.

Moore’s paradox, the infamous felt bizarreness of sincerely uttering something of the form “I believe grass is green, but it ain’t”—has attracted a lot of attention since its original discovery (Moore 1942). It is often taken to be a paradox of belief—in the sense that the locus of the inconsistency is the beliefs of someone who so sincerely utters. This claim has been labeled as the priority thesis: If you have an explanation of why a putative content could not be (...) coherently believed, you thereby have an explanation of why it cannot be coherently asserted. (Shoemaker 1995). The priority thesis, however, is insufficient to give a general explanation of Moore-paradoxical phenomena and, moreover, it’s false. I demonstrate this, then show how to give a commitment-theoretic account of Moore Paradoxicality, drawing on work by Bach and Harnish. The resulting account has the virtue of explaining not only cases of pragmatic incoherence involving assertions, but also cases of cognate incoherence arising for other speech acts, such as promising, guaranteeing, ordering, and the like.

Introspective evidence is still treated with great suspicion in cognitive science. This work is designed to encourage cognitive scientists to take more account of the subject's unique perspective.

The process of dehumanization, or thinking of others as less than human, is a phenomenon with significant societal implications. According to Haslam's model, two concepts of humanness derive from comparing humans with either animals or machines: individuals may be dehumanized by likening them to either animals or machines, or humanized by emphasizing differences from animals or machines. Recent work in cognitive neuroscience emphasizes understanding cognitive processes in terms of interactions between distributed cortical networks. It has been found that reasoning about (...) internal mental states is associated with activation of the default mode network and deactivation of the task positive network ; whereas reasoning about mechanical processes produces the opposite pattern. We conducted two neuroimaging studies. The first examined the neural bases of dehumanization and its relation to these two brain networks, using images and voice-over social narratives which either implicitly contrasted or implicitly likened humans to either animals or machines. The second study addressed a discrepancy between findings from the first study and prior work on the neural correlates of dehumanization: using a design similar to prior work we examined neural responses to pictures of humans, animals and machines, presented without any social context. In both studies, human and humanizing conditions were associated with relatively high activity in the DMN and relatively low activity in the TPN. However, the non-human and dehumanizing conditions deviated in different ways: they demonstrated more marked changes either in the DMN or in the TPN. Notably, differences between the animal dehumanizing and humanizing conditions were most evident in regions associated with mechanistic reasoning, not in the mentalizing network. Conjunction analysis of contrasts from both paradigms revealed that only one region was consistently more active when participants saw human, a medial parietal region regarded as the central hub of the DMN. These findings provide a neural basis for Haslam's distinction between two types of dehumanization, and suggest that the DMN and TPN play opposing roles in creating a sense of moral concern.

Nominalists are confronted with a grave difficulty: if abstract objects do not exist, what explains the success of theories that invoke them? In this paper, I make headway on this problem. I develop a formal language in which certain platonistic claims about properties and certain nominalistic claims can be expressed, develop a formal language in which only certain nominalistic claims can be expressed, describe a function mapping sentences of the first language to sentences of the second language, and prove some (...) facts about that function and facts about some sound logics for those languages. In doing so, I prove that, given some plausible metaphysical assumptions, a large class of sentences about properties of concrete objects are “safe” on nominalistic grounds. Whenever some true sentences about concrete objects and some sentences belonging to this class that are true according to platonists collectively entail a conclusion about concrete objects, some nominalistically acceptable sentences are true and entail the same conclusion. Because the proof can itself be formulated without abstract objects, it provides a nominalistic explanation of the success of theories that invoke properties of concrete objects. (shrink)

Ascriptions of objectivity carry significant weight. But they can also cause confusion because wildly different ideas of what it means to be objective are common. Faced with this, some philosophers have argued that objectivity should be eliminated. I will argue, against one such position, that objectivity can be useful even though it is plural. I will then propose a contextualist approach for dealing with objectivity as a way of rescuing what is useful about objectivity while acknowledging its plurality.

In this paper, we will introduce a novel argument (the “Region Argument”) that objects do not have frame-independent shapes in special relativity. The Region Argument lacks vulnerabilities present in David Chalmers' argument for that conclusion based on length contraction. We then examine how views on persistence interact with the Region Argument. We argue that this argument and standard four-dimensionalist assumptions entail that nothing in a relativistic world has any shape, not even stages or the regions occupied by them. We also (...) argue that endurantists have viable ways of preserving shape despite the Region Argument. The upshot of these arguments is that contrary to conventional wisdom, considerations about shape in relativity support endurantism rather than four-dimensionalism. We conclude by examining the implications of our discussion for the debate over Edenic shapes, noting that endurantists have a satisfying response to skeptical arguments about Edenic shapes similar to the one they have against the Region Argument.

I defend normative subjectivism against the charge that believing in it undermines the functional role of normative judgment. In particular, I defend it against the claim that believing that our reasons change from context to context is problematic for our use of normative judgments. To do so, I distinguish two senses of normative universality and normative reasons---evaluative universality and reasons and ontic universality and reasons. The former captures how even subjectivists can evaluate the actions of those subscribing to other conventions; (...) the latter explicates how their reasons differ from ours. I then show that four aspects of the functional role of normativity---evaluation of our and others actions and reasons, normative communication, hypothetical planning, and evaluating counternromative conditionals---at most requires our normative systems being evaluatively universal. Yet reasonable subjectivist positions need not deny evaluative universality. (shrink)

The history of the Frankfurt School cannot be fully told without examining the relationships of Critical Theorists to their Jewish family backgrounds. Jewish matters had significant effects on key figures in the Frankfurt School, including Max Horkheimer, Theodor W. Adorno, Erich Fromm, Leo Lowenthal and Herbert Marcuse. At some points, their Jewish family backgrounds clarify their life paths; at others, these backgrounds help to explain why the leaders of the School stressed the significance of antisemitism. In the post-Second World War (...) era, the differing relationships of Critical Theorists to their Jewish origins illuminate their distinctive stances toward Israel. This book investigates how the Jewish backgrounds of major Critical Theorists, and the ways in which they related to their origins, impacted upon their work, the history of the Frankfurt School, and differences that emerged among them over time.

The world is said to contain crystal balls whenever the present carries news of the as-yet-undetermined parts of the future. Many philosophers believe that crystal balls are metaphysically possible. In this essay, I argue that they are not. Whether crystal balls are possible matters, for at least two reasons. The first is epistemological. According to a simple, user-friendly chance norm for credence, which I call the Present Principle, agents are rationally required to conform their credences to their expectations of the (...) present chances, deferring to the present chances as they would to an expert. I would like to defend the Present Principle since its truth would do much to simplify the relation between chance and credence. But the Present Principle is counterexample-free, and hence defensible, only if crystal balls are impossible. The second reason is decision-theoretic. The problem of crystal balls is one of the main objections to causal decision theory. But crystal ball cases can be counterexample to causal decision theory only if crystal balls are possible, and, as I argue, crystal balls are not possible. (shrink)

Mark Blaug and I agree that if there is a realist interpretation of economic behavior to be discerned in Friedman, it is to be found not in Friedman's belief that the profit motive overrides other possible motives, but in his belief that a selection mechanism is working in competitive markets. Our joint sympathy for evolutionary economics is largely based on a conviction that the conception of competition as a dynamic evolutionary process is rather plausible. We disagree, however, on two issues: (...) first, how important the evolutionary conception was for Friedman's overall argument; and, second, whether we can learn something about the real world from rigorous formal analytical models. In this article, I explain and argue for my position on these two issues, and use Nelson and Winter's theory of evolutionary economics to support an illustrate my argument. (shrink)

Alan Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight.

Imitators of God: Leibniz on Human Freedom JACK DAVIDSON QUESTIONS CONCERNING DIVINE AND HUMAN FREEDOM mattered to Leibniz. He found the problems surrounding these issues important and difficult to solve, at one point writing: "There are two labyrinths of the human mind: one concerns the composition of the continuum, and the other the nature of freedom" : Although there is no unanimity among scholars about the details to his solution to the labyrinth of freedom, most have thought that Leibniz (...) is a compatibilist: Lately, however, some commentators have charged that, appearances to the contrary, Leibniz is actually an incom- patibilist about freedom.3 This new reading is exciting and important because ' All works of Leibniz are cited by page number unless otherwise indicated. The first citation is to a source in the original language. Where they exist, the English translation of the same passage is cited next. I want to thank Robert Sleigh for making available original-language sources not available in libraries, and for his generosity in sharing translations. In this paper I follow his translation of the Confessio Philosophi and of ~Du Franc Arbitre" .

In lieu of an abstract, here is a brief excerpt of the content:Rudolf A. Makkreel 1936-2021Jack Zupko, Former Editor, Journal of the History of PhilosophyRudi Makkreel, longtime editor (1983–98) of the Journal of the History of Philosophy and President of its Board of Directors (1998–2018), died October 2021 in Atlanta, GA, of complications from ALS.Rudi was one of the foremost Kant scholars of his generation, helping to bring the Critique of Judgment into the broader currency it enjoys among philosophers today. (...) He also made important contributions to the fields of aesthetics, hermeneutics, and the philosophy of history. His Dilthey, Philosopher of the Human Studies (Princeton, 1975; 2nd edition, 1992), nominated for both a Pulitzer Prize and a National Book Award, introduced the thought of Wilhelm Dilthey to the anglophone world, explaining the significance of Dilthey’s work on the social and cultural dimensions of human experience as well as its influence on early analytic philosophers such as Carnap. With Frithjof Rodi, he completed the six-volume Wilhelm Dilthey: Selected Works (Princeton, 1985–2019), an enduring legacy for students and historians of German philosophy of the late nineteenth and early twentieth centuries.Rudi was born in Antwerp, Belgium in 1939. He immigrated to the United States in 1951 and completed his graduate studies in philosophy at Columbia University in 1966. He taught at the University of California, San Diego until 1973, after which he joined the faculty at Emory University, his academic home as Charles Howard Candler Professor of Philosophy for almost half a century. He was a native Dutch speaker, but equally at home in both English and German, always exemplifying for his students the importance of knowing the original languages of the philosophers one is researching.Rudi was not just a scholar’s scholar but a perceptive critic and outstanding teacher, as his many students in academic positions around the world can attest. As a colleague he was unfailingly supportive, in his gentle and softly spoken way, quietly putting opportunities in the path of younger historians of philosophy. He was committed to ensuring the Emory philosophy program remained solidly grounded in the history of philosophy, with faculty expertise in all of its canonical areas. He was dedicated to his students and to serving the profession through the JHP, guiding the work of its Board of Directors and providing invaluable advice (though only when asked) to later Editors.Rudi took over editorship of the JHP at a tumultuous time in its history; he brought stability to its operations and ensured that the JHP remained a “big tent” in the field, publishing research on all figures, movements, and periods in the history of western philosophy, by scholars with a variety of philosophical styles and research methods. This meant making room for original papers on understudied figures and topics, despite the pressure to publish the best work on better-known figures and more traditional or popular topics, with which he could have easily filled each issue.He leaves behind his wife, Frances, a daughter, Karen, and a grandchild, as well as many former students and colleagues, who miss his gentle demeanor, wry sense of humor, and penetrating intellect.Jack Zupko, Former Editor, Journal of the History of PhilosophyUniversity of AlbertaCopyright © 2023 Journal of the History of Philosophy, Inc....

The acceptance of the concept of necessary linguistic cate­gories has given renewed prominence to the subject of ontology in contemporary discussions of language and logic. Jack Kaminsky, Professor of Philosophy at the State University of New York at Binghamton, here contributes an important expo­sition of this school of thought. He examines the views of many philosophers who either admit or deny that ontological com­mitments are necessary, and he raises broad questions and shows why there is a compelling interest in (...) the relation of a formal language to the issue of ontological inquiry.

One of the best gimmicks on the cognitive science conference circuit is the demonstration of inattentional blindness. Many readers of this journal must have already been exposed to it. For the rest we will briefly describe a striking and popular demonstration. It typically evolves during a conference talk, where the presenter provides the audience with a stimulus in the form of a small video clip of six people, three in white, three in black, who pass two basket balls around. The (...) instruction is to count the number of passes made by the players in white. When the movie is over, the presenter asks for a response, someone provides it, and he then goes on to elicit a report: 'Did anyone notice something strange during the film?' Usually, only those who have seen the film before have, but they are not allowed to answer. The film is then replayed, but this time, the audience is instructed to look out for anything unusual. Muted, surprised laughter goes through the auditorium when someone dressed as a gorilla enters into the scene of kids playing, confronts the spectators, bangs his chest, and slowly walks out again. It seems incredible that it went unnoticed the first time around, and yet those who have been exposed to the experiment before can testify that the gorilla was indeed there in both showings of the film.

In a recent paper Copi has argued for the admission of the term “essence” into scientific terminology. His primary reason is that the increasing adequacy of scientific theories is evidence of a gradual approximation to the real essences of things. Copi is aware that the laws of modern science are not to be taken as formulations of essences. But, he claims, “that is an ideal towards which science strives… Centuries hence wiser men will have radically different and more adequate theories, (...) and their notions will be closer approximations than ours to the real essences of things.”.

Corrigibility has generally been designated as the major qualification of a scientific law. Although various other characteristics of a scientific law have been questioned, corrigibility has usually been accepted as one of its essential features. On this basis scientists, positivists, and pragmatists have frequently distinguished between genuine empirical laws and all other assertions that only seem to be laws. The mark of a genuine law in the scientific sense is its corrigibility; the mark of a pseudo law is its non-corrigibility. (...) In this paper I should like to reopen philosophic inquiry into the nature of corrigibility as it is supposedly exemplified in law and to call attention to some of the peculiar difficulties and conclusions attendant on any such inquiry.
