  2. Prisoners of Abstraction? The Theory and Measure of Genetic Variation, and the Very Concept of 'Race'.Jonathan Michael Kaplan & Rasmus Grønfeldt Winther - 2013 - Biological Theory 7 (1):401-412.
    It is illegitimate to read any ontology about "race" off of biological theory or data. Indeed, the technical meaning of "genetic variation" is fluid, and there is no single theoretical agreed-upon criterion for defining and distinguishing populations (or groups or clusters) given a particular set of genetic variation data. Thus, by analyzing three formal senses of "genetic variation"—diversity, differentiation, and heterozygosity—we argue that the use of biological theory for making epistemic claims about "race" can only seem plausible when it relies (...)

  3. On the concept of biological race and its applicability to humans.Massimo Pigliucci & Jonathan Kaplan - 2003 - Philosophy of Science 70 (5):1161-1172.
    Biological research on race has often been seen as motivated by or lending credence to underlying racist attitudes; in part for this reason, recently philosophers and biologists have gone through great pains to essentially deny the existence of biological human races. We argue that human races, in the biological sense of local populations adapted to particular environments, do in fact exist; such races are best understood through the common ecological concept of ecotypes. However, human ecotypic races do not in general (...)

  4. Realism, Antirealism, and Conventionalism about Race.Jonathan Michael Kaplan & Rasmus Grønfeldt Winther - 2014 - Philosophy of Science 81 (5):1039-1052.
    This paper distinguishes three concepts of "race": bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards' 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially crucial to the first episode, while normativity is central to the second. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. We conclude by interrogating (...)

    This is a story about three of my favorite philosophers—Donnellan, Russell, and Frege—about how Donnellan’s concept of having in mind relates to ideas of the others, and especially about an aspect of Donnellan’s concept that has been insufficiently discussed: how this epistemic state can be transmitted from one person to another.

    All eyes are turned towards genomic data and models as the source of knowledge about whether human races exist or not. Will genomic science make the final decision about whether racial realism (e.g., racial population naturalism) or anti-realism (e.g., racial skepticism) is correct? We think not. We believe that the results of even our best and most impressive genomic technologies underdetermine whether bio-genomic races exist, or not. First, different sub-disciplines of biology interested in population structure employ distinct concepts, aims, measures, (...)

    Twenty years have passed since Gould and Lewontin published their critique of ‘the adaptationist program’ – the tendency of some evolutionary biologists to assume, rather than demonstrate, the operation of natural selection. After the ‘Spandrels paper’, evolutionists were more careful about producing just-so stories based on selection, and paid more attention to a panoply of other processes. Then came reactions against the excesses of the anti-adaptationist movement, which ranged from a complete dismissal of Gould and Lewontin’s contribution to a positive (...)

  9. The problem with descriptive correctness.Jeffrey Kaplan - 2020 - Ratio 33 (2):79-86.
    In the 1980s and early 1990s, the normativity of meaning was thought to be more-or-less 'incontestable.' But in the last 25 years, many philosophers of mind and language have contested it in several seemingly different ways. This, however, is somewhat illusory. There is an unappreciated commonality among most anti-normativist arguments, and this commonality, I argue, poses a problem for anti-normativism. The result, however, is not a wholesale rejection of anti-normativism. Rather, an insight from the anti-normativist position can be harnessed to (...)

    Fiona Macpherson (2012) argues that various experimental results provide strong evidence in favor of the cognitive penetration of perceptual color experience. Moreover, she proposes a mechanism for how such cognitive penetration occurs. We argue, first, that the results on which Macpherson relies do not provide strong grounds for her claim of cognitive penetrability; and, second, that, if the results do reflect cognitive penetrability, then time-course considerations raise worries for her proposed mechanism. We base our arguments in part on several of (...)

  12. Gould on Morton, Redux: What can the debate reveal about the limits of data?Jonathan Kaplan, Massimo Pigliucci & Joshua Banta - 2015 - Studies in History and Philosophy of Biological and Biomedical Sciences 52:22-31.
    Lewis et al. (2011) attempted to restore the reputation of Samuel George Morton, a 19th century physician who reported on the skull sizes of different folk-races. Whereas Gould (1978) claimed that Morton’s conclusions were invalid because they reflected unconscious bias, Lewis et al. alleged that Morton’s findings were, in fact, supported, and Gould’s analysis biased. We take strong exception to Lewis et al.’s thesis that Morton was “right.” We maintain that Gould was right to reject Morton’s analysis as inappropriate and (...)

  13. Attitude and Social Rules, or Why It's Okay to Slurp Your Soup.Jeffrey Kaplan - 2021 - Philosophers' Imprint 21 (28).
    Many of the most important social institutions—e.g., law and language—are thought to be normative in some sense. And philosophers have been puzzled by how this normativity can be explained in terms of the social, descriptive states of affairs that presumably constitute them. This paper attempts to solve this sort of puzzle by considering a simpler and less contentious normative social practice: table manners. Once we are clear on the exact sense in which a practice is normative, we see that some (...)

  14. Attitude and the normativity of law.Jeffrey Kaplan - 2017 - Law and Philosophy 36 (5):469-493.
    Though legal positivism remains popular, HLA Hart’s version has fallen somewhat by the wayside. This is because, according to many, the central task of a theory of law is to explain the so-called ‘normativity of law’. Hart’s theory, it is thought, is not up to the task. Some have suggested modifying the theory accordingly. This paper argues that both Hart’s theory and the normativity of law have been misunderstood. First, a popular modification of Hart’s theory is considered and rejected. It (...)

    This paper presents a series of arguments aimed at showing that, for an important subclass of social rules—non‐summary rules—no adequate metaphysical account has been given, and it tentatively suggests that no such account can be given. The category of non‐summary rules is an important one, as it includes the rules of etiquette, fashion, chess, basketball, California state law, descriptive English grammar, and so on. This paper begins with behavioristic accounts of the conditions for the existence of such rules, and proceeds (...)

    This article examines how facial recognition technology reshapes the philosophical debate over the ethics of video surveillance. When video surveillance is augmented with facial recognition, the data collected is no longer anonymous, and the data can be aggregated to produce detailed psychological profiles. I argue that – as this non-anonymous data of people’s mundane activities is collected – unjust risks of harm are imposed upon individuals. In addition, this technology can be used to catalogue all who publicly participate in political, (...)

    The most discussed theory of law of the twentieth century – HLA Hart’s theory from _The Concept of Law_ – is fundamentally _psychological_. It explains the existence of legal systems in terms of an attitude taken by legal officials: the internal point of view. Though much has been said about this attitude (what statements _express_ it, what it is _not_, how Hart _ought_ to have conceived of it, etc.), we nonetheless lack an adequate account of the attitude itself.

  21. The structure of semantic norms.Jeffrey Kaplan - 2023 - Analytic Philosophy 64 (4):373-391.
    The normativity of meaning—introduced by Kripke in 1982, and the subject of active debate since the early 1990s—has been exclusively understood in terms of duty-imposing norms. But there are norms of another type, well-known within the philosophy of law: authority-conferring norms. Philosophers thinking and writing about the normativity of meaning—normativists, anti-normativists, and even Kripke himself—seem to have failed to consider the possibility that semantic norms are authority-conferring. I argue that semantic norms should be understood as having an authority-conferring structure, and (...)

    In this paper, I examine the ethics of nonviolent protest when a violent response is either foreseen or intended. One central concern is whether protesters, who foresee a violent response but persist, are provoking the violence and whether they are culpable for any eventual harms. A second concern is whether it is permissible to publicize the violent response for political advantage. I begin by distinguishing between two senses of the term provoke: a normative sense where a provocateur knowingly imposes an (...)

    Expressivism in logic is the view that logical vocabulary plays a primarily expressive role: that is, that logical vocabulary makes perspicuous in the object language structural features of inference and incompatibility (Brandom, 1994, 2008). I present a precise, technical criterion of expressivity for a logic (§2). I next present a logic that meets that criterion (§3). I further explore some interesting features of that logic: first, a representation theorem for capturing other logics (§3.1), and next some novel logical vocabulary for (...)

His contribution to the understanding of prosocial behavior would also benefit from abandoning the traditional (and excessively restrictive) definition of altruism.

    The works of the later Wittgenstein resonate with aspects of the pragmatist tradition in American philosophy. Davidson’s work is similarly informed. We argue that because of their association with the pragmatist tradition, their work can be put to use by philosophers interested in social justice issues, including, for example, feminism, and critical race theory. Philosophers concerned with social justice continue to struggle between the extremes of an untenable foundationalism and a radical relativism.
