  1. Surprises in logic.John Corcoran & William Frank - 2013 - Bulletin of Symbolic Logic 19 (3):253.
    JOHN CORCORAN AND WILIAM FRANK. Surprises in logic. Bulletin of Symbolic Logic. 19 253. Some people, not just beginning students, are at first surprised to learn that the proposition “If zero is odd, then zero is not odd” is not self-contradictory. Some people are surprised to find out that there are logically equivalent false universal propositions that have no counterexamples in common, i. e., that no counterexample for one is a counterexample for the other. Some people would be surprised (...)

  2. Evolution, Dysfunction, and Disease: A Reappraisal.Paul E. Griffiths & John Matthewson - 2018 - British Journal for the Philosophy of Science 69 (2):301-327.
    Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...)

  3. On the logic of the ontological argument.Paul E. Oppenheimer & Edward N. Zalta - 1991 - Philosophical Perspectives 5:509-529.
    In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...)

  4. Fragmented and conflicted: folk beliefs about vision.Paul E. Engelhardt, Keith Allen & Eugen Fischer - 2023 - Synthese 201 (3):1-33.
    Many philosophical debates take for granted that there is such a thing as ‘the’ common-sense conception of the phenomenon of interest. Debates about the nature of perception tend to take for granted that there is a single, coherent common-sense conception of vision, consistent with Direct Realism. This conception is often accorded an epistemic default status. We draw on philosophical and psychological literature on naïve theories and belief fragmentation to motivate the hypothesis that untutored common sense encompasses conflicting Direct Realist and (...)

  5. What are biological sexes?Paul E. Griffiths - manuscript
    Biological sexes (male, female, hermaphrodite) are defined by different gametic strategies for reproduction. Sexes are regions of phenotypic space which implement those gametic reproductive strategies. Individual organisms pass in and out of these regions – sexes - one or more times during their lives. Importantly, sexes are life-history stages rather than applying to organisms over their entire lifespan. This fact has been obscured by concentrating on humans, and ignoring species which regularly change sex, as well as those with non-genetic or (...)

  6. Virtue Habituation and the Skill of Emotion Regulation.Paul E. Carron - 2021 - In Tom P. S. Angier & Lisa Ann Raphals (eds.), Skill in Ancient Ethics: The Legacy of China, Greece and Rome. New York: Bloomsbury Academic. pp. pp. 115-140.
    In Nicomachean Ethics 2.1, Aristotle draws a now familiar analogy between aretai ('virtues') and technai ('skills'). The apparent basis of this comparison is that both virtue and skill are developed through practice and repetition, specifically by the learner performing the same kinds of actions as the expert: in other words, we become virtuous by performing virtuous actions. Aristotle’s claim that “like states arise from like activities” has led some philosophers to challenge the virtue-skill analogy. In particular, Aristotle’s skill analogy is (...)

  7. Experimental ordinary language philosophy: a cross-linguistic study of defeasible default inferences.Eugen Fischer, Paul E. Engelhardt, Joachim Horvath & Hiroshi Ohtani - 2019 - Synthese 198 (2):1029-1070.
    This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...)

  8. Ludwig Edinger: The vertebrate series and comparative neuroanatomy.Paul E. Patton - 2014 - Journal of the History of the Neurosciences 24 (1):26-57.
    At the end of the nineteenth century, Ludwig Edinger completed the first comparative survey of the microscopic anatomy of vertebrate brains. He is regarded as the founder of the field of comparative neuroanatomy. Modern commentators have misunderstood him to have espoused an anti-Darwinian linear view of brain evolution, harkening to the metaphysics of the scala naturae. This understanding arises, in part, from an increasingly contested view of nineteenth-century morphology in Germany. Edinger did espouse a progressionist, though not strictly linear, view (...)

  9. Epistemic tools and epistemic agents in Scientonomy.Paul E. Patton - 2019 - Scientonomy: Journal for the Science of Science 3:63-89.
    The only subtype of epistemic agent currently recognized within scientonomy is community. The place of both individuals and epistemic tools in the scientonomic ontology is yet to be clarified. This paper extends the scientonomic ontology to include epistemic agents and epistemic tools as well as their relationship to one another. Epistemic agent is defined as an agent capable of taking epistemic stances towards epistemic elements. These stances must be taken intentionally, that is, based on a semantic understanding of the epistemic (...)

    Teaching at a private, conservative religious institution poses unique challenges for equality, diversity, and inclusivity education (EDI). Given the realities of the student population in the Honors College of a private, religious institution, it is necessary to first introduce students to the contemporary realities of inequality and oppression and thus the need for EDI. This chapter proposes a conceptual framework and pedagogical suggestions for teaching basic concepts of social justice in a team-taught, interdisciplinary social science course. The course integrates four (...)

  12. Stereotypical Inferences: Philosophical Relevance and Psycholinguistic Toolkit.Eugen Fischer & Paul E. Engelhardt - 2017 - Ratio 30 (4):411-442.
    Stereotypes shape inferences in philosophical thought, political discourse, and everyday life. These inferences are routinely made when thinkers engage in language comprehension or production: We make them whenever we hear, read, or formulate stories, reports, philosophical case-descriptions, or premises of arguments – on virtually any topic. These inferences are largely automatic: largely unconscious, non-intentional, and effortless. Accordingly, they shape our thought in ways we can properly understand only by complementing traditional forms of philosophical analysis with experimental methods from psycholinguistics. This (...)

    This new study of the “First” Crusade argues that “apocalyptic fervor” (p. 305) was the driving force of the expedition, as well as the Crusade movement. Previous studies, the author contends, have failed “to capture how precisely apocalyptic the First Crusade was” (p. xii). The remedy Rubenstein offers is a relentless focus on apocalypticism that ignores any weaknesses inherent in this approach and overlooks alternative explanations.

  14. Intuitions' Linguistic Sources: Stereotypes, Intuitions and Illusions.Eugen Fischer & Paul E. Engelhardt - 2016 - Mind and Language 31 (1):67-103.
    Intuitive judgments elicited by verbal case-descriptions play key roles in philosophical problem-setting and argument. Experimental philosophy's ‘sources project’ seeks to develop psychological explanations of philosophically relevant intuitions which help us assess our warrant for accepting them. This article develops a psycholinguistic explanation of intuitions prompted by philosophical case-descriptions. For proof of concept, we target intuitions underlying a classic paradox about perception, trace them to stereotype-driven inferences automatically executed in verb comprehension, and employ a forced-choice plausibility-ranking task to elicit the relevant (...)

  15. Diagnostic Experimental Philosophy.Eugen Fischer & Paul E. Engelhardt - 2017 - Teorema: International Journal of Philosophy 36 (3):117-137.
    Experimental philosophy’s much-discussed ‘restrictionist’ program seeks to delineate the extent to which philosophers may legitimately rely on intuitions about possible cases. The present paper shows that this program can be (i) put to the service of diagnostic problem-resolution (in the wake of J.L. Austin) and (ii) pursued by constructing and experimentally testing psycholinguistic explanations of intuitions which expose their lack of evidentiary value: The paper develops a psycholinguistic explanation of paradoxical intuitions that are prompted by verbal case-descriptions, and presents two (...)

    Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks — from the way monkeys in a troop communicate, to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this paper, we argue there is a tension between how Skyrms talks of signalling networks and his (...)

    Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...)

    This article explores the notion of pedagogical authority as exercised in the Community of Inquiry, the method for facilitating Philosophy for Children (P4C). It argues that the teachers’ pedagogical authority in a Community of Inquiry is not predicated on their intellectual superiority or status. Rather it finds its legitimacy in their role as instigators of students’ thinking skills, which are assumed to be already possessed by the learners. This thesis is discussed in relation to Rancière’s concept of the dissociation of (...)

  19. Philosophers' linguistic expertise: A psycholinguistic approach to the expertise objection against experimental philosophy.Eugen Fischer, Paul E. Engelhardt & Aurélie Herbelot - 2022 - Synthese 200 (1):1-33.
    Philosophers are often credited with particularly well-developed conceptual skills. The ‘expertise objection’ to experimental philosophy builds on this assumption to challenge inferences from findings about laypeople to conclusions about philosophers. We draw on psycholinguistics to develop and assess this objection. We examine whether philosophers are less or differently susceptible than laypersons to cognitive biases that affect how people understand verbal case descriptions and judge the cases described. We examine two possible sources of difference: Philosophers could be better at deploying concepts, (...)

    In this article, I intend to underscore the importance of critical thinking in rendering invaluable positive contributions and impact within professional organizations in the developing world. I argue that critical thinking treated as a normative principle and balanced with a pragmatic orientation provides a rational framework for resolving conflicts that oftentimes ensue from the incoherence between Western-based organizational theories and the actual circumstances of a developing country. In order to optimize the benefits of critical thinking, I also argue that it (...)

  22. Socratic Meditation and Emotional Self-Regulation: Human Dignity in a Technological Age.Anne-Marie Schultz & Paul E. Carron - 2013 - Journal of Interdisciplinary Studies 25 (1-2):137-160.
    This essay proposes that Socrates practiced various spiritual exercises, including meditation, and that this Socratic practice of meditation was habitual, aimed at cultivating emotional self-control and existential preparedness. Contemporary research in neurobiology supports the view that intentional mental actions, including meditation, have a profound impact on brain activity, neuroplasticity, and help engender emotional self-control. This impact on brain activity is confirmed via technological developments, a prime example of how technology benefits humanity. Socrates attains the balanced emotional self-control that Alcibiades describes (...)

    The task of this chapter is to investigate and assess Grossmann’s view of the ontological status of categories. It has two dimensions. Because Grossmann does not offer a full discussion of the ontology of categories, we first need to present an interpretation of his view. Our point of departure is Grossmann’s claim that a category is a fundamental property of being (which implies that he holds view 3 above). Our second task is to assess the adequacy of his view.

  24. The Blind Hens’ Challenge: Does it Undermine the View that Only Welfare Matters in Our Dealings with Animals?Peter Sandøe, Paul M. Hocking, Bjorn Förkman, Kirsty Haldane, Helle H. Kristensen & Clare Palmer - 2014 - Environmental Values 23 (6):727-742.
    Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are both empirical and (...)

    What are the freedom-relevant conditions necessary for someone to be a morally responsible person? I examine several key authors beginning with Harry Frankfurt that have contributed to this debate in recent years, and then look back to the writings or Søren Kierkegaard to provide a solution to the debate. In this project I investigate the claims of semi-compatibilism and argue that while its proponents have identified a fundamental question concerning free will and moral responsibility—namely, that the agential properties necessary for (...)

    Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...)

    Psycholinguistic methods hold great promise for experimental philosophy. Many philosophical thought experiments and arguments proceed from verbal descriptions of possible cases. Many relevant intuitions and conclusions are driven by spontaneous inferences about what else must also be true in the cases described. Such inferences are continually made in language comprehension and production. This chapter explains how methods from psycholinguistics can be employed to study such routine automatic inferences, with a view to assessing intuitions and reconstructing arguments. We demonstrate how plausibility (...)

Aristotle makes no distinction between causal and moral responsibility in the NE; rather, voluntariness and prohairesis form different bases for responsibility and make possible different levels of responsibility, but both levels of responsibility fall within the ethical sphere and are aptly appraised.

Philosophy, University at Buffalo, Buffalo, NY 14260-4150 USA E-mail: corcoran@buffalo.edu Filosofia, Universidade Federal de Goiás, Goiás, GO 74001-970 Brazil E-mail: [email protected] -/- Consider two doxastic states belief and disbelief. Belief is taking a proposition to be true and disbelief taking it to be false. Judging also dichotomizes: accepting a proposition results in belief and rejecting in disbelief. Stating follows suit: asserting a proposition conveys belief and denying conveys disbelief. (...)

  43. Existential Import Today: New Metatheorems; Historical, Philosophical, and Pedagogical Misconceptions.John Corcoran & Hassan Masoud - 2015 - History and Philosophy of Logic 36 (1):39-61.
    Contrary to common misconceptions, today's logic is not devoid of existential import: the universalized conditional ∀ x [S→ P] implies its corresponding existentialized conjunction ∃ x [S & P], not in all cases, but in some. We characterize the proexamples by proving the Existential-Import Equivalence: The antecedent S of the universalized conditional alone determines whether the universalized conditional has existential import, i.e. whether it implies its corresponding existentialized conjunction.A predicate is an open formula having only x free. An existential-import predicate (...)

  44. Sentence, Proposition, Judgment, Statement, and Fact: Speaking about the Written English Used in Logic.John Corcoran - 2009 - In W. A. Carnielli (ed.), The Many Sides of Logic. College Publications. pp. 71-103.
    The five English words—sentence, proposition, judgment, statement, and fact—are central to coherent discussion in logic. However, each is ambiguous in that logicians use each with multiple normal meanings. Several of their meanings are vague in the sense of admitting borderline cases. In the course of displaying and describing the phenomena discussed using these words, this paper juxtaposes, distinguishes, and analyzes several senses of these and related words, focusing on a constellation of recommended senses. One of the purposes of this paper (...)

  45. (1 other version)LOGIC TEACHING IN THE 21ST CENTURY.John Corcoran - 2016 - Quadripartita Ratio: Revista de Argumentación y Retórica 1 (1):1-34.
    We are much better equipped to let the facts reveal themselves to us instead of blinding ourselves to them or stubbornly trying to force them into preconceived molds. We no longer embarrass ourselves in front of our students, for example, by insisting that “Some Xs are Y” means the same as “Some X is Y”, and lamely adding “for purposes of logic” whenever there is pushback. Logic teaching in this century can exploit the new spirit of objectivity, humility, clarity, observationalism, (...)

  46. equality and identity.John Corcoran & Anthony Ramnauth - 2013 - Bulletin of Symbolic Logic 19 (3):255-256.
    Equality and identity. Bulletin of Symbolic Logic. 19 (2013) 255-6. (Coauthor: Anthony Ramnauth) Also see https://www.academia.edu/s/a6bf02aaab This article uses ‘equals’ [‘is equal to’] and ‘is’ [‘is identical to’, ‘is one and the same as’] as they are used in ordinary exact English. In a logically perfect language the oxymoron ‘the numbers 3 and 2+1 are the same number’ could not be said. Likewise, ‘the number 3 and the number 2+1 are one number’ is just as bad from a logical point (...)

  47. Through the Lens of Virtual Students: Challenges and Opportunities.Joseph A. Villarama, John Paul E. Santos, Joseph P. Adsuara, Jordan F. Gundran & Marius Engelbert Geoffrey C. Castillo - 2022 - International Journal of Learning, Teaching and Educational Research 21 (10):109-138.
    Quarantines and virtual learning became necessary as a result of the COVID-19 pandemic. This study investigates the challenges and opportunities in virtual classes; and how they affect the academic goals. There were 150 secondary students from Junior and Senior High School levels of education in the Philippines, who were deliberately selected; and they participated in the quantitative online survey that used a 62-item self-made 4-point Likert scale questionnaire, with 0.81 reliability coefficients. The data were evaluated by means of the percentage, (...)

  48. REVIEW OF 1988. Saccheri, G. Euclides Vindicatus (1733), edited and translated by G. B. Halsted, 2nd ed. (1986), in Mathematical Reviews MR0862448. 88j:01013.John Corcoran - 1988 - MATHEMATICAL REVIEWS 88 (J):88j:01013.
    Girolamo Saccheri (1667--1733) was an Italian Jesuit priest, scholastic philosopher, and mathematician. He earned a permanent place in the history of mathematics by discovering and rigorously deducing an elaborate chain of consequences of an axiom-set for what is now known as hyperbolic (or Lobachevskian) plane geometry. Reviewer's remarks: (1) On two pages of this book Saccheri refers to his previous and equally original book Logica demonstrativa (Turin, 1697) to which 14 of the 16 pages of the editor's "Introduction" are devoted.

In Silico Approaches and the Role of Ontologies in Aging Research.Georg Fuellen, Melanie Börries, Hauke Busch, Aubrey de Grey, Udo Hahn, Thomas Hiller, Andreas Hoeflich, Ludger Jansen, Georges E. Janssens, Christoph Kaleta, Anne C. Meinema, Sascha Schäuble, Paul N. Schofield, Barry Smith & Others - 2013 - Rejuvenation Research 16 (6):540-546.
    The 2013 Rostock Symposium on Systems Biology and Bioinformatics in Aging Research was again dedicated to dissecting the aging process using in silico means. A particular focus was on ontologies, as these are a key technology to systematically integrate heterogeneous information about the aging process. Related topics were databases and data integration. Other talks tackled modeling issues and applications, the latter including talks focussed on marker development and cellular stress as well as on diseases, in particular on diseases of kidney (...)

  50. Gordon Pask’s Conversation Theory and Interaction of Actors Theory: Research to Practice.Shantanu Tilak, Thomas Manning, Michael Glassman, Paul Pangaro & Bernard C. E. Scott - 2024 - Enacting Cybernetics 2 (1):1-22.
    This three-part paper presents Gordon Pask’s conversation theory (CT) and interaction of actors theory (IA) and outlines ways to apply these cybernetic approaches to designing technologies and scenarios for both formal and informal learning. The first part of the paper covers concepts central to CT and IA, explaining the relationship between conceptual and mechanical operators, and machines mediating informal and formal learning. The second part of the paper applies visual representations of CT and IA to understanding the use of Pask’s (...)
