  2. Fluted formulas and the limits of decidability.William C. Purdy - 1996 - Journal of Symbolic Logic 61 (2):608-620.
    In the predicate calculus, variables provide a flexible indexing service which selects the actual arguments to a predicate letter from among possible arguments that precede the predicate letter (in the parse of the formula). In the process of selection, the possible arguments can be permuted, repeated (used more than once), and skipped. If this service is withheld, so that arguments must be the immediately preceding ones, taken in the order in which they occur, the formula is said to be fluted. (...)

    Complexity and nicety of fluted logic.William C. Purdy - 2002 - Studia Logica 71 (2):177 - 198.
    Fluted Logic is essentially first-order predicate logic deprived of variables. The lack of variables results in reduced expressiveness. Nevertheless, many logical problems that can be stated in natural language, such as the famous Schubert's Steamroller, can be rendered in fluted logic. Further evidence of the expressiveness of fluted logic is its close relation to description logics. Already it has been shown that fluted logic is decidable and has the finite-model property. This paper shows that fluted logic has the exponential-model property (...)

    Quine's 'limits of decision'.William C. Purdy - 1999 - Journal of Symbolic Logic 64 (4):1439-1466.
    In a 1969 paper, Quine coined the term 'limits of decision'. This term evidently refers to limits on the logical vocabulary of a logic, beyond which satisfiability is no longer decidable. In the same paper. Quine showed that not only monadic formulas, but homogeneous k-adic formulas for arbitrary k lie on the decidable side of the limits of decision. But the precise location of the limits of decision has remained an open question. The present paper answers that question. It addresses (...)

    Decidability of Fluted Logic with Identity.William C. Purdy - 1996 - Notre Dame Journal of Formal Logic 37 (1):84-104.
    Fluted logic is the restriction of pure predicate logic to formulas in which variables play no essential role. Although fluted logic is significantly weaker than pure predicate logic, it is of interest because it seems closely to parallel natural logic, the logic that is conducted in natural language. It has been known since 1969 that if conjunction in fluted formulas is restricted to subformulas of equal arity, satisfiability is decidable. However, the decidability of sublogics lying between this restricted (homogeneous) fluted (...)

    Modeling: Neutral, Null, and Baseline.William C. Bausman - 2018 - Philosophy of Science 85 (4):594-616.
    Two strategies for using a model as “null” are distinguished. Null modeling evaluates whether a process is causally responsible for a pattern by testing it against a null model. Baseline modeling measures the relative significance of various processes responsible for a pattern by detecting deviations from a baseline model. When these strategies are conflated, models are illegitimately privileged as accepted until rejected. I illustrate this using the neutral theory of ecology and draw general lessons from this case. First, scientists cannot (...)

    From biological practice to scientific metaphysics.William C. Bausman, Janella K. Baxter & Oliver M. Lean (eds.) - 2023 - Minneapolis: University of Minnesota Press.
    Exploring what a scientific metaphysics grounded in biological practices could look like and how it might impact the way we investigate the world around us, the contributors to From Biological Practice to Scientific Metaphysics review and discuss long-held objections to metaphysics by natural scientists. They illuminate how, in order to learn about the world as it truly is, we must look not only at what scientists say but also what they do.

  16. The Role of Starting Points to Order Investigation: Why and How to Enrich the Logic of Research Questions.William C. Bausman - 2022 - Philosophy, Theory, and Practice in Biology 6 (14).
    What methodological approaches do research programs use to investigate the world? Elisabeth Lloyd’s Logic of Research Questions (LRQ) characterizes such approaches in terms of the questions that the researchers ask and causal factors they consider. She uses the Logic of Research Questions Framework to criticize adaptationist programs in evolutionary biology for dogmatically assuming selection explanations of the traits of organisms. I argue that Lloyd’s general criticism of methodological adaptationism is an artefact of the impoverished LRQ. My Ordered Factors Proposal extends (...)

    Mysticism versus Philosophy in earlier Islamic History: The Al–Tūsi, Al–Qūnawi correspondence: WILLIAM C. CHITTICK.William C. Chittick - 1981 - Religious Studies 17 (1):87-104.
    To say ‘mysticism versus philosophy’ in the context of Islamic civilization means something far different from what it has come to signify in the West, where many philosophers have looked upon mysticism as the abandonment of any attempt to reconcile religious data with intelligent thought. Certainly the Muslim mystics and philosophers sometimes display a certain mutual opposition and antagonism, but never does their relationship even approach incompatibility.

    Kierkegaard on the Transformation of the Individual in Conversion: WILLIAM C.DAVIS.William C. Davis - 1992 - Religious Studies 28 (2):145-163.
    From at least the time of the writing of The Philosophical Fragments , Søren Kierkegaard's work takes a special interest in both the transition from unbelief to faith and the character of the life of true faith. Trained in Lutheran dogma and convinced of the radical nature of human freedom, his work on this subject demonstrates a profound concern for and grasp of Lutheran orthodoxy, as well as a remarkable degree of subtlety. After all, it is no simple task to (...)

  20. The heart of Islamic philosophy: the quest for self-knowledge in the teachings of Afḍal al-Dīn Kāshānī.William C. Chittick - 2001 - New York: Oxford University Press.
    This book introduces the work of an important medieval Islamic philosopher who is little known outside the Persian world. Afdal al-Din Kashani was a contemporary of a number of important Muslim thinkers, including Averroes and Ibn al-Arabi. Kashani did not write for advanced students of philosophy but rather for beginners. In the main body of his work, he offers especially clear and insightful expositions of various philosophical positions, making him an invaluable resource for those who would like to learn the (...)

    The moral authority of transnational corporate codes.William C. Frederick - 1991 - Journal of Business Ethics 10 (3):165 - 177.
    Ethical guidelines for multinational corporations are included in several international accords adopted during the past four decades. These guidelines attempt to influence the practices of multinational enterprises in such areas as employment relations, consumer protection, environmental pollution, political participation, and basic human rights. Their moral authority rests upon the competing principles of national sovereignty, social equity, market integrity, and human rights. Both deontological principles and experience-based value systems undergird and justify the primacy of human rights as the fundamental moral authority (...)

    Can Ethnographers Contribute to an Anti-Torture Movement in the Middle East?William C. Young - 2000 - Global Bioethics 13 (1-2):5-13.
    Although campaigns for universal human rights have been intellectually and emotionally compelling for many anthropologists, they have tended to embroil them in fruitless polemics about cultural relativism with non-Western thinkers and policy-makers. Often “universalist” discourses about “rights” depend on values and distinctions that are far from universal and that stem, in fact, from Christian, secular, or “modernist” notions about punishment, suffering, and redemption. To make some practical contribution to the struggle for human dignity in the Middle East, it may be (...)

    Ricoeur on Time and Narrative: An Introduction to Temps Et Récit.William C. Dowling - 2011 - University of Notre Dame Press.
    “The object of this book,” writes William C. Dowling in his preface, “is to make the key concepts of Paul Ricoeur’s _Time and Narrative_ available to readers who might have felt bewildered by the twists and turns of its argument.” The sources of puzzlement are, he notes, many. For some, it is Ricoeur’s famously indirect style of presentation, in which the polarities of argument and exegesis seem so often and so suddenly to have reversed themselves. For others, it is (...)

    Moving to CSR.William C. Frederick - 1998 - Business and Society 37 (1):40-59.
    The study of Social Issues in Management (SIM) has exhausted its primary analytic framework based on corporate social performance (social science), business ethics (philosophy), and stakeholder theory (organizational science), and needs to move to a new paradigmatic level based on the natural sciences. Doing so would expand research horizons to include cosmological perspectives (astrophysics), evolutionary theory (biology, genetics, ecology), and non-sectarian spirituality concepts (theological naturalism, cognitive neuroscience). Absent this shift, SIM studies risk increasing irrelevance for scholars and business practitioners.

    Though the phrase 'x is true of x' is well formed grammatically, it does not express any predicate in the logical sense, because it does not satisfy the principle of reduction for statements containing 'x is true of'. recognition of this allows for solution of russell's paradox without his restrictive theory of types.

    Advantage, adaptiveness, and evolutionary ecology.William C. Kimler - 1986 - Journal of the History of Biology 19 (2):215-233.
    With the rejection of group selectionist derivations of ecological phenomena so incisively given by George Williams in 1966,43 Nicholson's long-ignored messages met with acceptance. Species benefit became, explicitly, incidental. But the reorientation was not just about a point of ecological theory. It was more fundamentally about theoretical style, the element shared by Wynne-Edwards' work and the newer, evolutionary ecology. That current approach is well expressed in an already classic paper by the British plant ecologist John Harper: Ultimately all the discoveries (...)

    Although genocide—a coordinated plan of different actions aiming at the destruction of essential foundations of the life of national groups, with the aim of annihilating the groups themselves—remains a sickeningly frequent phenomenon in the twenty‐first century, it is not an immutable aspect of the human condition. Genocide is a choice, and the civilized world must choose its demise. The unique experience of American Indians—a group subjected to genocide in the process of the creation and expansion of the United States—presents a (...)

    Consequences of the inertial equivalence of energy.William C. Davidon - 1975 - Foundations of Physics 5 (3):525-542.
    The usual macroscopic theory of relativistic mechanics and electromagnetism is formulated so that all assumptions but one are consistent with both special relativity and Newtonian mechanics, the distinguishing assumption being that to any energyE, whatever its form, there corresponds an inertial massE/c 2 . The speed of light enters this formulation only as a consequence of the inertial equivalent of energy1/c 2 . While, for1/c 2 >0 the resulting theory has symmetry under the Poincaré group, including Lorentz transformations, all its (...)

    In early 1984, the AIDS epidemic was less than four years old. Chemists at the pharmaceutical company Syntex, situated in the rolling green hills near Stanford University in Palo Alto, California, had recently synthesized a new antiviral drug (Martin et al. 1983). The drug, at first given the awkward chemical abbreviation DHPG, later came to be known by the generic name ganciclovir. Ganciclovir was a potent drug for the treatment of herpes virus infection (such as genital herpes or chickenpox), but (...)
