  1. A First Course in Logic: An Introduction to Model Theory, Proof Theory, Computability, and Complexity.Shawn Hedman - 2004 - Oxford, England: Oxford University Press.
    The ability to reason and think in a logical manner forms the basis of learning for most mathematics, computer science, philosophy and logic students. Based on the author's teaching notes at the University of Maryland and aimed at a broad audience, this text covers the fundamental topics in classical logic in an extremely clear, thorough and accurate style that is accessible to all the above. Covering propositional logic, first-order logic, and second-order logic, as well as proof theory, computability theory, and (...)

    CSR-Washing is Rare: A Conceptual Framework, Literature Review, and Critique.Shawn Pope & Arild Wæraas - 2016 - Journal of Business Ethics 137 (1):173-193.
    Growth in CSR-washing claims in recent decades has been dramatic in numerous academic and activist contexts. The discourse, however, has been fragmented, and still lacks an integrated framework of the conditions necessary for successful CSR-washing. Theorizing successful CSR-washing as the joint occurrence of five conditions, this paper undertakes a literature review of the empirical evidence for and against each condition. The literature review finds that many of the conditions are either highly contingent, rendering CSR-washing as a complex and fragile outcome. (...)

    Invoices on Scraps of Paper: Trust and Reciprocity in Local Food Systems.Shawn Trivette - 2017 - Agriculture and Human Values 34 (3):529-542.
    One of the many claims about the value of local food is that local food exchanges generate trust between producers and consumers. To what degree is this actually the case and how does such trust develop? Drawing on interview and fieldwork data in one local food system in the Northeastern U.S., I show how local food participants build trust and reciprocity with one another in order to mitigate the challenges imposed by the conventional system. This trust and reciprocity builds primarily (...)

    How Local is Local? Determining the Boundaries of Local Food in Practice.Shawn A. Trivette - 2015 - Agriculture and Human Values 32 (3):475-490.
    This paper addresses the question of how local can be defined in practice. It contributes to the growing literature on local food systems and particularly our understanding of what counts as local and the elements that influence those contours. While most of our conceptions of local food tend to rely on an articulation of either proximity traveled or relationship between entities, I argue that a more nuanced and complete understanding must take account of both of these aspects. I draw on (...)

    The Importance of Food Retailers: Applying Network Analysis Techniques to the Study of Local Food Systems.Shawn A. Trivette - 2019 - Agriculture and Human Values 36 (1):77-90.
    As local food activities expand and grow, an important question to answer is how various participants contribute to a local food system’s overall vitality and strength. This paper does so by focusing on the relationships between locally-oriented farm and retail actors and assessing what the configuration of these relationships tells us about the workings of the broader local food system. Such an analysis reveals two things. Empirically, it shows the important role food retailers play in the overall vibrancy of local (...)

  11. Contraction and Revision.Shawn Standefer - 2016 - Australasian Journal of Logic 13 (3):58-77.
    An important question for proponents of non-contractive approaches to paradox is why contraction fails. Zardini offers an answer, namely that paradoxical sentences exhibit a kind of instability. I elaborate this idea using revision theory, and I argue that while instability does motivate failures of contraction, it equally motivates failure of many principles that non-contractive theorists want to maintain.

    Solovay-Type Theorems for Circular Definitions.Shawn Standefer - 2015 - Review of Symbolic Logic 8 (3):467-487.
    We present an extension of the basic revision theory of circular definitions with a unary operator, □. We present a Fitch-style proof system that is sound and complete with respect to the extended semantics. The logic of the box gives rise to a simple modal logic, and we relate provability in the extended proof system to this modal logic via a completeness theorem, using interpretations over circular definitions, analogous to Solovay’s completeness theorem forGLusing arithmetical interpretations. We adapt our proof to (...)

    Actual Issues for Relevant Logics.Shawn Standefer - 2020 - Ergo: An Open Access Journal of Philosophy 7.
    In this paper, I motivate the addition of an actuality operator to relevant logics. Straightforward ways of doing this are in tension with standard motivations for relevant logics, but I show how to add the operator in a way that permits one to maintain the intuitions behind relevant logics. I close by exploring some of the philosophical consequences of the addition.

    Can a man intend to do the impossible? That is, can a man undertake to do some action, A—and not merely to come as close as possible to doing A with the hope that the doing of A will result—when he believes he has no chance of doing A?

    Solidarity: A (New) Ethic for Global Health Policy. [REVIEW]Shawn H. E. Harmon - 2006 - Health Care Analysis 14 (4):215-236.
    This article explores solidarity as an ethical concept underpinning rules in the global health context. First, it considers the theoretical conceptualisation of the value and some specific duties it supports (ie: its expression in the broadest sense and its derivative action-guiding duties). Second, it considers the manifestation of solidarity in two international regulatory instruments. It concludes that, although solidarity is represented in these instruments, it is often incidental. This fact, their emphasis on other values and their internal weaknesses diminishes the (...)

    Proof Theory for Functional Modal Logic.Shawn Standefer - 2018 - Studia Logica 106 (1):49-84.
    We present some proof-theoretic results for the normal modal logic whose characteristic axiom is \. We present a sequent system for this logic and a hypersequent system for its first-order form and show that these are equivalent to Hilbert-style axiomatizations. We show that the question of validity for these logics reduces to that of classical tautologyhood and first-order logical truth, respectively. We close by proving equivalences with a Fitch-style proof system for revision theory.

    Translations Between Gentzen–Prawitz and Jaśkowski–Fitch Natural Deduction Proofs.Shawn Standefer - 2019 - Studia Logica 107 (6):1103-1134.
    Two common forms of natural deduction proof systems are found in the Gentzen–Prawitz and Jaśkowski–Fitch systems. In this paper, I provide translations between proofs in these systems, pointing out the ways in which the translations highlight the structural rules implicit in the systems. These translations work for classical, intuitionistic, and minimal logic. I then provide translations for classical S4 proofs.

    Tracking Reasons with Extensions of Relevant Logics.Shawn Standefer - 2019 - Logic Journal of the IGPL 27 (4):543-569.
    In relevant logics, necessary truths need not imply each other. In justification logic, necessary truths need not all be justified by the same reason. There is an affinity to these two approaches that suggests their pairing will provide good logics for tracking reasons in a fine-grained way. In this paper, I will show how to extend relevant logics with some of the basic operators of justification logic in order to track justifications or reasons. I will define and study three kinds (...)

    Non-Classical Circular Definitions.Shawn Standefer - 2017 - Australasian Journal of Logic 14 (1).
    Circular denitions have primarily been studied in revision theory in the classical scheme. I present systems of circular denitions in the Strong Kleene and supervaluation schemes and provide complete proof systems for them. One class of denitions, the intrinsic denitions, naturally arises in both schemes. I survey some of the features of this class of denitions.

    An Ethical Framework for Cardiac Report Cards: A Qualitative Study. [REVIEW]Shawn Richard, Shail Rawal & Douglas Martin - 2005 - BMC Medical Ethics 6 (1):1-7.
    Background The recent proliferation of health care report cards, especially in cardiac care, has occurred in the absence of an ethical framework to guide in their development and implementation. An ethical framework is a consistent and comprehensive theoretical foundation in ethics, and is formed by integrating ethical theories, relevant literature, and other critical information (such as the views of stakeholders). An ethical framework in the context of cardiac care provides guidance for developing cardiac report cards (CRCs) that are relevant and (...)

    This paper defends “Animal Universalism,” the thesis that all sentient non-human animals will be brought into Heaven and remain there for eternity. It assumes that God exists and is all-powerful, perfectly loving, and perfectly just. From these background theses, the authors argue that Animal Universalism follows. If God is perfectly loving, then God is concerned about the well-being of non-human animals, and God chooses to maximize the well-being of each individual animal when doing so does not harm other individual creatures (...)

  29. God and Moral Perfection.Shawn Graves - 2014 - Oxford Studies in Philosophy of Religion 5:122-146.
    One will be hard-pressed to find a morally perfect agent in this world. It’s not that there aren’t any morally good people. It just takes a lot to be morally perfect. However, theists claim that God is morally perfect. (Atheists claim that if God exists, God is morally perfect.) Perhaps they are mistaken. This chapter presents an argument for the conclusion that God is not morally perfect. The argument depends upon two things: (1) the nature of the concept of moral (...)

    In Saving Truth from Paradox, Hartry Field presents and defends a theory of truth with a new conditional. In this paper, I present two criticisms of this theory, one concerning its assessments of validity and one concerning its treatment of truth-preservation claims. One way of adjusting the theory adequately responds to the truth-preservation criticism, at the cost of making the validity criticism worse. I show that in a restricted setting, Field has a way to respond to the validity criticism. I (...)

    The Self-Undermining Objection to the Epistemology of Disagreement.Shawn Graves - 2013 - Faith and Philosophy 30 (1):93-106.
    Disagreements about, within, and between religions are widespread. It’s no surprise, then, that there’s an enormous philosophical literature on religious diversity. But in recent years, philosophers working in mainstream epistemology have done a lot of work on disagreement in general. This work has focused in particular upon the epistemology of peer disagreement, i.e., disagreements between parties who are justifiably believed to be epistemic equals regarding the matter at hand. In this paper, I intend to defend a thesis in the epistemology (...)

It then considers how and whether these concerns are dealt with in regulatory instruments in (...)

    BackgroundAs a number of commentators have noted, SARS exposed the vulnerabilities of our health care systems and governance structures. Health care professionals and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCPs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were exposed (...)

    We argue that distinct conditionals—conditionals that are governed by different logics—are needed to formalize the rules of Truth Introduction and Truth Elimination. We show that revision theory, when enriched with the new conditionals, yields an attractive theory of truth. We go on to compare this theory with one recently proposed by Hartry Field.

    Unraveling Emergency Justifications and Excuses for Terrorism.Shawn Kaplan - 2011 - Journal of Social Philosophy 42 (2):219-238.
    This paper examines recent arguments by Michael Walzer and Uwe Steinhoff for justifying or excusing indiscriminate terrorism by means of invoking ‘emergency’ circumstances. While both authors claim that the principle of non-combatant immunity can be justifiably overridden under extreme circumstances, it is argued here that neither provides a convincing argument as to when and why the survival of some innocents ought to counterbalance the harms or rights violations of indiscriminate terrorism. A defensible emergency justification for indiscriminate terrorism is proposed and (...)

  41. The Relevant Logic E and Some Close Neighbours: A Reinterpretation.Edwin Mares & Shawn Standefer - 2017 - IfCoLog Journal of Logics and Their Applications 4 (3):695--730.
    This paper has two aims. First, it sets out an interpretation of the relevant logic E of relevant entailment based on the theory of situated inference. Second, it uses this interpretation, together with Anderson and Belnap’s natural deduc- tion system for E, to generalise E to a range of other systems of strict relevant implication. Routley–Meyer ternary relation semantics for these systems are produced and completeness theorems are proven. -/- .

My approach considers Heidegger's philosophy of art in order to develop some outlines of a Heideggerian philosophy of film. I also consider some aspects of Terrence Malick's films viewed as exemplar instances of the philosophical theory of film Heidegger's work can support.

    In order to address whether states can ever have the proper authority to militarily punish other international agents, I examine three attempts to justify punitive warfare from Augustine, Grotius and Locke for their relevance to both our contemporary international legal and political order and our contemporary security threats from sporadic terrorist or militant violence. Once a plausible model for a state’s valid authority to punish international agents is found, I will consider what punitive aims it can support and what challenges (...)

    Evidentialism: Feldman on Having Evidence.Shawn Graves - 2014 - Journal of Philosophical Research 39:265-283.
    Richard Feldman and Ram Neta have recently noted that philosophers give relatively little attention to specifying the conditions under which S has something as evidence at a time. This issue is significant to evidentialists. Evidentialism states that which doxastic attitude S is epistemically justified in taking toward a proposition at a time depends upon what is supported by the total evidence S has at that time. What we regard as being necessary and sufficient for S’s having something as evidence partly (...)

    The recent outbreak of Ebola in West Africa has killed thousands of people, including healthcare workers. African responses have been varied and largely ineffective. The WHO and the international community’s belated responses have yet to quell the epidemic. The crisis is characteristic of a failure to properly comply with the International Health Regulations 2005. More generally, it stems from a failure of international health justice as articulated by a range of legal institutions and instruments, and it should prompt us to (...)
