  1. The aesthetic appeal of minimal structures: Judging the attractiveness of solutions to traveling salesperson problems.D. Vickers, M. Lee, M. Dry, P. Hughes & Jennifer A. McMahon - 2007 - Perception and Psychophysics 68 (1):32-42.
    Ormerod and Chronicle reported that optimal solutions to traveling salesperson problems were judged to be aesthetically more pleasing than poorer solutions and that solutions with more convex hull nodes were rated as better figures. To test these conclusions, solution regularity and the number of potential intersections were held constant, whereas solution optimality, the number of internal nodes, and the number of nearest neighbors in each solution were varied factorially. The results did not support the view that the convex hull is (...)

  2. Quantum-like non-separability of concept combinations, emergent associates and abduction.P. Bruza, K. Kitto, B. Ramm, L. Sitbon & D. Song - 2012 - Logic Journal of the IGPL 20 (2):445-457.
    Consider the concept combination ‘pet human’. In word association experiments, human subjects produce the associate ‘slave’ in relation to this combination. The striking aspect of this associate is that it is not produced as an associate of ‘pet’, or ‘human’ in isolation. In other words, the associate ‘slave’ seems to be emergent. Such emergent associations sometimes have a creative character and cognitive science is largely silent about how we produce them. Departing from a dimensional model of human conceptual space, this (...)

    Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...)

    Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...)

  12. Geach and Ascriptivism: Beside the Point.Luís Duarte D'Almeida - 2016 - Journal for the History of Analytical Philosophy 4 (6).
    This paper discusses the first incarnation of what came to be known as the “Frege-Geach” point. The point was made by Peter Geach in his 1960 essay “Ascriptivism”, and developed in “Assertion”, a 1965 piece. Geach’s articles launch a wholesale attack on theories of non-descriptive performances advanced by “some Oxford philosophers” whom he accuses of ignoring “the distinction between calling a thing ‘P’ and predicating ‘P’ of a thing”. One view that Geach specifically targets is H. L. A. Hart’s claim (...)

  13. Emily Thomas (red.): Early Modern Women on Metaphysics.Oda K. S. Davanger - 2018 - Norsk Filosofisk Tidsskrift 53 (2-3):171-175.
    På mange måter er dette en bok som blir utgitt alt for sent. Det er den første antologien av sitt slag, og retter fokus på kvinnelige metafysikere som virket i den tidlige moderne perioden (16. og tidlig 17. århundre). Redaktør Emily Thomas skriver i introduksjonen at til tross for at flere antologier om moderne metafysikk allerede finnes, er kvinnelige filosofer fortsatt underrepresentert og den filosofiske kanon mannsdominert. De ni filosofene som blir omtalt i totalt 13 kapitler var alle originale og (...)

    Let us imagine an ideal ethical agent, i.e., an agent who (i) holds a certain ethical theory, (ii) has all factual knowledge needed for determining which action among those open to her is right and which is wrong, according to her theory, and who (iii) is ideally motivated to really do whatever her ethical theory demands her to do (even when she speaks). If we grant that the notions of omniscience and ideal motivation both make sense, we may ask: Could (...)

  17. Verschmierte Spuren der Unfreiheit: Wissenschaftsphilosophische Klarstellung zu angeblichen Artefakten bei Benjamin Libet.Olaf L. Müller - 2013 - Philosophia Naturalis 50 (1):45-83.
    Benjamin Libet's celebrated experiments concerning freedom elicited numerous attempts of _philosophical_ repudiation. Ten years ago, however, Judy Trevena and Jeff Miller published a _technical_ objection; they claim to have detected a,,smearing artifact" in Libet's calculations. This rests on a misunderstanding of Libet's methodology. In my reconstruction of Libet's argument, he draws an abductive inference to the best explanation. Now, Trevena's and Miller's objection does indeed lead to alternative explanations of Libet's measurements. These alternatives are _ad hoc_ and extremely improbable. They (...)

  18. Kant’s conception of proper science.Hein van den Berg - 2011 - Synthese 183 (1):7-26.
    Kant is well known for his restrictive conception of proper science. In the present paper I will try to explain why Kant adopted this conception. I will identify three core conditions which Kant thinks a proper science must satisfy: systematicity, objective grounding, and apodictic certainty. These conditions conform to conditions codified in the Classical Model of Science. Kant’s infamous claim that any proper natural science must be mathematical should be understood on the basis of these conditions. In order to substantiate (...)

    Sprachliche Ausdrücke, mit deren Hilfe wir Spiele beschreiben und vorantreiben, sind in ihrer Verwendungsweise so vielfältig wie kaum irgendwelche anderen Ausdrücke. Und sie haben eine Eigenschaft, die man mit dem Thema Spiel eher nicht in Verbindung bringen würde: Sie eignen sich dazu, auf substantive Weise Metaphysik zu treiben oder wieder ingangzubringen. Diese Art der Starthilfe hat die jahrtausendealte Metaphysik (metaphysica specialis) neuerdings nötig. Seit knapp hundert Jahren steht sie im Verdacht, auf nichts besseres hinauszulaufen als leeres, unverständliches Wortgeklingel. Wer diesen (...)

  22. Mag Uidhir on performance.P. D. Magnus - 2008 - British Journal of Aesthetics 48 (3):338-345.
    Christy Mag Uidhir has recently argued (a) that there is no in principle aesthetic difference between a live performance and a recording of that performance, and (b) that the proper aesthetic object is a type which is instantiated by the performance and potentially repeatable when recordings are played back. This paper considers several objections to (a) and finds them lacking. I then consider improvised music, a subject that Mag Uidhir explicitly brackets in his discussion. Improvisation reveals problems with (b), because (...)

  23. 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 (...)

  24. 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 (...)

  27. No Grist for Mill on Natural Kinds.P. D. Magnus - 2014 - Journal for the History of Analytical Philosophy 2 (4).
    According to the standard narrative, natural kind is a technical notion that was introduced by John Stuart Mill in the 1840s and the recent craze for natural kinds, launched by Putnam and Kripke, is a continuation of that tradition. I argue that the standard narrative is mistaken. The Millian tradition of kinds was not particularly influential in the 20th-century, and the Putnam-Kripke revolution did not clearly engage with even the remnants that were left of it. The presently active tradition of (...)

  29. Kant and the scope of analogy in the life sciences.Hein van den Berg - 2018 - Studies in History and Philosophy of Science Part A 71:67-76.
    In the present paper I investigate the role that analogy plays in eighteenth-century biology and in Kant’s philosophy of biology. I will argue that according to Kant, biology, as it was practiced in the eighteenth century, is fundamentally based on analogical reflection. However, precisely because biology is based on analogical reflection, biology cannot be a proper science. I provide two arguments for this interpretation. First, I argue that although analogical reflection is, according to Kant, necessary to comprehend the nature of (...)

    An important artistic topic of Italian Renaissance painting was the rendering of the human figure. As leading actors in a painted narrative, figures had to convince beholders of the reality of the matter depicted with appropriated attitudes and gestures. This article is about two ways of drawing or rather constructing the human figure artists developed to achieve this goal. The first was only an adaptation to an old method: because of the rather simple and coarse elements used, constructions often resulted (...)

    In late 2014, the jazz combo Mostly Other People Do the Killing released Blue—an album that is a note-for-note remake of Miles Davis's 1959 landmark album Kind of Blue. This is a thought experiment made concrete, raising metaphysical puzzles familiar from discussion of indiscernible counterparts. It is an actual album, rather than merely a concept, and so poses the aesthetic puzzle of why one would ever actually listen to it.

  34. Generative AI and photographic transparency.P. D. Magnus - forthcoming - AI and Society:1-6.
    There is a history of thinking that photographs provide a special kind of access to the objects depicted in them, beyond the access that would be provided by a painting or drawing. What is included in the photograph does not depend on the photographer’s beliefs about what is in front of the camera. This feature leads Kendall Walton to argue that photographs literally allow us to see the objects which appear in them. Current generative algorithms produce images in response to (...)

  35. Realist Ennui and the Base Rate Fallacy.P. D. Magnus & Craig Callender - 2004 - Philosophy of Science 71 (3):320-338.
    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 (...)

  36. Scurvy and the ontology of natural kinds.P. D. Magnus - 2023 - Philosophy of Science 80 (5):1031-1039.
    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 (...)

  37. 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 (...)

  38. 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, (...)

  39. 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 (...)

  40. Electoral Dioramas: On the Problem of Representation in Voting Advice Applications.Thomas Fossen & Bert van den Brink - 2015 - Representation 51 (3):341-358.
    Voting Advice Applications (VAAs) are online tools designed to help citizens decide how to vote. They typically offer their users a representation of what is at stake in an election by matching user preferences on issues with those of parties or candidates. While the use of VAAs has boomed in recent years in both established and new democracies, this new phenomenon in the electoral landscape has received little attention from political theorists. The current academic debate is focused on epistemic aspects (...)

  41. Drakes, seadevils, and similarity fetishism.P. D. Magnus - 2011 - Biology and Philosophy 26 (6):857-870.
    Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. 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. (...)

  42. The scope of inductive risk.P. D. Magnus - 2022 - Metaphilosophy 53 (1):17-24.
    The Argument from Inductive Risk (AIR) is taken to show that values are inevitably involved in making judgements or forming beliefs. 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 (...)

  43. Miracles, Trust, and Ennui in Barnes’ Predictivism.P. D. Magnus - 2011 - Logos and Episteme 2 (1):103-114.
    Eric Barnes’ The Paradox of Predictivism is concerned primarily with two facts: predictivism (the fact that novel predictions play an important part in scientificconfirmation) and pluralism (the fact that scientific development is not just a matter of isolated individuals judging the truth, but at least partly a matter of trusting legitimate experts). In the middle part of the book, he peers through these two lenses at the tired realist scarecrow of the no-miracles argument. He attempts to reanimate this weatherworn realist (...)

  44. 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.

  45. Axiomatic Natural Philosophy and the Emergence of Biology as a Science.Hein van den Berg & Boris Demarest - 2020 - Journal of the History of Biology 53 (3):379-422.
    Ernst Mayr argued that the emergence of biology as a special science in the early nineteenth century was possible due to the demise of the mathematical model of science and its insistence on demonstrative knowledge. More recently, John Zammito has claimed that the rise of biology as a special science was due to a distinctive experimental, anti-metaphysical, anti-mathematical, and anti-rationalist strand of thought coming from outside of Germany. In this paper we argue that this narrative neglects the important role played (...)

  46. forall x: Calgary. An Introduction to Formal Logic (4th edition).P. D. Magnus, Tim Button, Robert Trueman, Richard Zach & Aaron Thomas-Bolduc - 2023 - Calgary: Open Logic Project.
    forall x: Calgary is a full-featured textbook on formal logic. It covers key notions of logic such as consequence and validity of arguments, the syntax of truth-functional propositional logic TFL and truth-table semantics, the syntax of first-order (predicate) logic FOL with identity (first-order interpretations), symbolizing English in TFL and FOL, and Fitch-style natural deduction proof systems for both TFL and FOL. It also deals with some advanced topics such as modal logic, soundness, and functional completeness. Exercises with solutions are available. (...)

  47. Hormone research as an exemplar of underdetermination.P. D. Magnus - 2005 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 36 (3):559-567.
    Debates about the underdetermination of theory by data often turn on specific examples. Cases invoked often enough become familiar, even well worn. Since Helen Longino’s discussion of the case, the connection between prenatal hormone levels and gender-linked childhood behaviour has become one of these stock examples. However, as I argue here, the case is not genuinely underdetermined. We can easily imagine a possible experiment to decide the question. The fact that we would not perform this experiment is a moral, rather (...)

  48. On Trusting Wikipedia.P. D. Magnus - 2009 - Episteme 6 (1):74-90.
    Given the fact that many people use Wikipedia, we should ask: Can we trust it? The empirical evidence suggests that Wikipedia articles are sometimes quite good but that they vary a great deal. As such, it is wrong to ask for a monolithic verdict on Wikipedia. Interacting with Wikipedia involves assessing where it is likely to be reliable and where not. I identify five strategies that we use to assess claims from other sources and argue that, to a greater of (...)

  49. A blooming and buzzing confusion: Buffon, Reimarus, and Kant on animal cognition.Hein van den Berg - 2018 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 72:1-9.
    Kant’s views on animals have received much attention in recent years. According to some, Kant attributed the capacity for objective perceptual awareness to non-human animals, even though he denied that they have concepts. This position is difficult to square with a conceptualist reading of Kant, according to which objective perceptual awareness requires concepts. Others take Kant’s views on animals to imply that the mental life of animals is a blooming, buzzing confusion. In this article I provide a historical reconstruction of (...)

  50. Kant’s Ideal of Systematicity in Historical Context.Hein van den Berg - 2021 - Kantian Review 26 (2):261-286.
    This article explains Kant’s claim that sciences must take, at least as their ideal, the form of a ‘system’. I argue that Kant’s notion of systematicity can be understood against the background of de Jong & Betti’s Classical Model of Science (2010) and the writings of Georg Friedrich Meier and Johann Heinrich Lambert. According to my interpretation, Meier, Lambert, and Kant accepted an axiomatic idea of science, articulated by the Classical Model, which elucidates their conceptions of systematicity. I show that (...)
