  1. Scientific enquiry and natural kinds: from planets to mallards.P. D. Magnus - 2012 - New York, NY: Palgrave-Macmillan.
    Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds. This book gives a general account of what it is to be a natural kind and puts the account to work illuminating numerous specific examples.

    The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...)

    There is considerable disagreement about the epistemic value of novel predictive success, i.e. when a scientist predicts an unexpected phenomenon, experiments are conducted, and the prediction proves to be accurate. We survey the field on this question, noting both fully articulated views such as weak and strong predictivism, and more nascent views, such as pluralist reasons for the instrumental value of prediction. By examining the various reasons offered for the value of prediction across a range of inferential contexts , we (...)

    The Homeostatic Property Cluster (HPC) account of natural kinds has become popular since it was proposed by Richard Boyd in the late 1980s. Although it is often taken as a defining natural kinds as such, it is easy enough to see that something's being a natural kind is neither necessary nor sufficient for its being an HPC. This paper argues that it is better not to understand HPCs as defining what it is to be a natural kind but instead as (...)

  5. Taxonomy, ontology, and natural kinds.P. D. Magnus - 2018 - Synthese 195 (4):1427-1439.
    When we ask what natural kinds are, there are two different things we might have in mind. The first, which I’ll call the taxonomy question, is what distinguishes a category which is a natural kind from an arbitrary class. The second, which I’ll call the ontology question, is what manner of stuff there is that realizes the category. Many philosophers have systematically conflated the two questions. The confusion is exhibited both by essentialists and by philosophers who pose their accounts in (...)

  6. Inductions, Red Herrings, and the Best Explanation for the Mixed Record of Science.P. D. Magnus - 2010 - British Journal for the Philosophy of Science 61 (4):803-819.
    Kyle Stanford has recently claimed to offer a new challenge to scientific realism. Taking his inspiration from the familiar Pessimistic Induction (PI), Stanford proposes a New Induction (NI). Contra Anjan Chakravartty’s suggestion that the NI is a ‘red herring’, I argue that it reveals something deep and important about science. The Problem of Unconceived Alternatives, which lies at the heart of the NI, yields a richer anti-realism than the PI. It explains why science falls short when it falls short, and (...)

    Some philosophers understand natural kinds to be the categories which are constraints on enquiry. In order to elaborate the metaphysics appropriate to such an account, I consider the complicated history of scurvy, citrus, and vitamin C. It may be tempting to understand these categories in a shallow way (as mere property clusters) or in a deep way (as fundamental properties). Neither approach is adequate, and the case instead calls for middle-range ontology: starting from categories which we identify in the world (...)

  8. John Stuart Mill on Taxonomy and Natural Kinds.P. D. Magnus - 2015 - Hopos: The Journal of the International Society for the History of Philosophy of Science 5 (2):269-280.
    The accepted narrative treats John Stuart Mill’s Kinds as the historical prototype for our natural kinds, but Mill actually employs two separate notions: Kinds and natural groups. Considering these, along with the accounts of Mill’s nineteenth-century interlocutors, forces us to recognize two distinct questions. First, what marks a natural kind as worthy of inclusion in taxonomy? Second, what exists in the world that makes a category meet that criterion? Mill’s two notions offer separate answers to the two questions: natural groups (...)

I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorphic species have things in common, namely dispositions or conditional properties. I argue that this response fails. (...)

  10. Art Concept Pluralism.Christy Mag Uidhir & P. D. Magnus - 2011 - Metaphilosophy 42 (1-2):83-97.
    Abstract: There is a long tradition of trying to analyze art either by providing a definition (essentialism) or by tracing its contours as an indefinable, open concept (anti-essentialism). Both art essentialists and art anti-essentialists share an implicit assumption of art concept monism. This article argues that this assumption is a mistake. Species concept pluralism—a well-explored position in philosophy of biology—provides a model for art concept pluralism. The article explores the conditions under which concept pluralism is appropriate, and argues that they (...)

After reviewing this conclusion, I pose cases which are prima facie counterexamples: the unreflective application of conventions, use of black-boxed instruments, reliance on opaque algorithms, and unskilled observation reports. These cases are counterexamples to the AIR posed in ethical terms as a matter of personal values. Nevertheless, it need not be understood in those terms. The values which load a (...)

  13. What Scientists Know Is Not a Function of What Scientists Know.P. D. Magnus - 2013 - Philosophy of Science 80 (5):840-849.
    There are two senses of ‘what scientists know’: An individual sense (the separate opinions of individual scientists) and a collective sense (the state of the discipline). The latter is what matters for policy and planning, but it is not something that can be directly observed or reported. A function can be defined to map individual judgments onto an aggregate judgment. I argue that such a function cannot effectively capture community opinion, especially in cases that matter to us.

    The problem of underdetermination is thought to hold important lessons for philosophy of science. Yet, as Kyle Stanford has recently argued, typical treatments of it offer only restatements of familiar philosophical problems. Following suggestions in Duhem and Sklar, Stanford calls for a New Induction from the history of science. It will provide proof, he thinks, of “the kind of underdetermination that the history of science reveals to be a distinctive and genuine threat to even our best scientific theories” (Stanford 2001, (...)

    The underdetermination of theory by evidence is supposed to be a reason to rethink science. It is not. Many authors claim that underdetermination has momentous consequences for the status of scientific claims, but such claims are hidden in an umbra of obscurity and a penumbra of equivocation. So many various phenomena pass for `underdetermination' that it's tempting to think that it is no unified phenomenon at all, so I begin by providing a framework within which all these worries can be (...)

First, many arguments do not show that values are, strictly speaking, indispensable. The role of values could in principle be filled by a random or arbitrary decision. Second, many arguments concern scientific theories and concepts which have obvious practical consequences, thus suggesting or at least leaving open the possibility that abstruse sciences without such a connection could be value-free.

Several accounts of science can be seen as global d-cog accounts: Robert Merton's sociology (...)

    The underdetermination of theory by data obtains when, inescapably, evidence is insufficient to allow scientists to decide responsibly between rival theories.

    It has been common wisdom for centuries that scientific inference cannot be deductive; if it is inference at all, it must be a distinctive kind of inductive inference. According to demonstrative theories of induction, however, important scientific inferences are not inductive in the sense of requiring ampliative inference rules at all. Rather, they are deductive inferences with sufficiently strong premises. General considerations about inferences suffice to show that there is no difference in justification between an inference construed demonstratively or ampliatively. (...)

  44. Preserving the Autographic/Allographic Distinction.Jason D'cruz & P. D. Magnus - 2015 - Journal of Aesthetics and Art Criticism 73 (4):453-457.
    The primary concern of our 2014 paper was not notation but the autographic/allographic distinction, not representations as such but works of art. As we see it, Zeimbekis's considerations do not ultimately undermine the position we advanced in 2014— but they do challenge an element of Goodman's own theory of notation that derives from his requirement of recoverability. That requirement can be abandoned without losing the explanatory power of the autographic/allographic distinction as we have refined it.

  45. Friends with benefits! Distributed cognition hooks up cognitive and social conceptions of science.P. D. Magnus & Ron McClamrock - 2015 - Philosophical Psychology 28 (8):1114-1127.
    One approach to science treats science as a cognitive accomplishment of individuals and defines a scientific community as an aggregate of individual inquirers. Another treats science as a fundamentally collective endeavor and defines a scientist as a member of a scientific community. Distributed cognition has been offered as a framework that could be used to reconcile these two approaches. Adam Toon has recently asked if the cognitive and the social can be friends at last. He answers that they probably cannot, (...)

  46. What Kind of Is-Ought Gap is There and What Kind Ought There Be?P. D. Magnus & Jon Mandle - 2017 - Journal of Moral Philosophy 14 (4):373-393.
    Some philosophers think that there is a gap between is and ought which necessarily makes normative enquiry a different kind of thing than empirical science. This position gains support from our ability to explicate our inferential practices in a way that makes it impermissible to move from descriptive premises to a normative conclusion. But we can also explicate them in a way that allows such moves. So there is no categorical answer as to whether there is or is not a (...)

  47. What SPECIES can teach us about THEORY.P. D. Magnus - manuscript
    This paper argues against the common, often implicit view that theories are some specific kind of thing. Instead, I argue for theory concept pluralism: There are multiple distinct theory concepts which we legitimately use in different domains and for different purposes, and we should not expect this to change. The argument goes by analogy with species concept pluralism, a familiar position in philosophy of biology. I conclude by considering some consequences for philosophy of science if theory concept pluralism is correct.

  48. Reality, sex, and cyberspace.P. D. Magnus - 2000 - In MacHack conference proceedings.
    Typical discussions of virtual reality (VR) fixate on technology for providing sensory stimulation of a certain kind. They thus fail to understand reality as the place wherein we live and work, misunderstanding it instead as merely a sort of presentation. The first half of the paper examines popular conceptions of VR. The most common conception is a shallow one according to which VR is a matter of simulating appearances. Yet there is, even in popular depictions, a second, more subtle conception (...)

  49. Appreciating covers.Cristyn Magnus, P. D. Magnus, Christy Mag Uidhir & Ron Mcclamrock - 2022 - Nordic Journal of Aesthetics 31 (63).
    A recording or performance of a song is a cover if there is an earlier, canonical recording of the song. It can seem intuitive to think that properly appreciating a cover requires considering it in relation to the original, or at least that doing so will yield a deeper appreciation. This intuition is supported by some philosophical accounts of covers. And it is complicated by the possibility of hearing in, whereby one hears elements of the original version in the cover. (...)

  50. Evidential nihilism.P. D. Magnus - 2020 - Analysis 80 (4):674-683.
    A considerable literature has grown up around the claim of Uniqueness, according to which evidence rationally determines belief. It is opposed to Permissivism, according to which evidence underdetermines belief. This paper highlights an overlooked third possibility, according to which there is no rational doxastic attitude. I call this 'Nihilism'. I argue that adherents of the other two positions ought to reject it but that it might, nevertheless, obtain at least sometimes.
