  1. Libertarian Law and Military Defense.Robert P. Murphy - 2017 - Libertarian Papers 9:213-232.
    Joseph Newhard (2017) argues that a libertarian anarchist society would be at a serious military disadvantage if it extended the nonaggression principle to include potential foreign invaders. He goes so far as to recommend cultivating the ability to launch a nuclear attack on foreign cities. In contrast, I argue that the free society would derive its strength from a total commitment to property rights and the protection of innocent life. Both theory and history suggest that a free society would be (...)

    Suspension-to-Suspension Justification Principles.Peter Murphy - forthcoming - Belgrade Philosophical Annual.
    We will be in a better position to evaluate some important skeptical theses if we first investigate two questions about justified suspended judgment. One question is this: when, if ever, does one justified suspension confer justification on another suspension? And the other is this: what is the structure of justified suspension? The goal of this essay is to make headway at answering these questions. After surveying the four main views about the non-normative nature of suspended judgment and offering a taxonomy (...)

  3. In Defense of Sensitivity.Tim Black & Peter Murphy - 2007 - Synthese 154 (1):53-71.
    The sensitivity condition on knowledge says that one knows that P only if one would not believe that P if P were false. Difficulties for this condition are now well documented. Keith DeRose has recently suggested a revised sensitivity condition that is designed to avoid some of these difficulties. We argue, however, that there are decisive objections to DeRose’s revised condition. Yet rather than simply abandoning his proposed condition, we uncover a rationale for its adoption, a rationale which suggests a (...)

    Sontag on Impertinent Sympathy and Photographs of Evil.Sean T. Murphy - forthcoming - In Colin Marshall (ed.), Comparative Metaethics: Neglected Perspectives on the Foundations of Morality. Routledge.
    This chapter corrects for Susan Sontag's undeserved neglect by contemporary ethical philosophers by bringing awareness to some of the unique metaethical insights born of her reflections on photographic representations of evil. I argue that Sontag's thought provides fertile ground for thinking about: (1) moral perception and its relation to moral knowledge; and (2) the epistemic and moral value of our emotional responses to the misery and suffering of others. I show that, contrary to standard moral perception theory (e.g. Blum 1994), (...)

    Justified Belief From Unjustified Belief.Peter Murphy - 2017 - Pacific Philosophical Quarterly 98 (4):602-617.
    Under what conditions is a belief inferentially justified? A partial answer is found in Justification from Justification : a belief is inferentially justified only if all of the beliefs from which it is essentially inferred are justified. After reviewing some important features of JFJ, I offer a counterexample to it. Then I outline a positive suggestion for how to think about inferentially justified beliefs while still retaining a basing condition. I end by concluding that epistemologists need a model of inferentially (...)

Preston, Harker Rhodes & Emily R. Murphy - 2010 - American Journal of Bioethics Neuroscience 1 (2):15-17.
    In this open peer commentary, we categorize the possible “neuroscience in national security” definitions of misuse of science and identify which, if any, are uniquely presented by advances in neuroscience. To define misuse, we first define what we would consider appropriate use: the application of reasonably safe and effective technology, based on valid and reliable scientific research, to serve a legitimate end. This definition presents distinct opportunities for assessing misuse: misuse is the application of invalid or unreliable science, or is (...)

  11. Genetic Modifications for Personal Enhancement: A Defense.Timothy F. Murphy - 2013 - Journal of Medical Ethics (4):2012-101026.
    Bioconservative commentators argue that parents should not take steps to modify the genetics of their children even in the name of enhancement because of the damage they predict for values, identities and relationships. Some commentators have even said that adults should not modify themselves through genetic interventions. One commentator worries that genetic modifications chosen by adults for themselves will undermine moral agency, lead to less valuable experiences and fracture people's sense of self. These worries are not justified, however, since the (...)

  16. Assessing Capability Instead of Achieved Functionings in Risk Analysis.Colleen Murphy & Paolo Gardoni - 2010 - Journal of Risk Research 13 (2):137-147.
    A capability approach has been proposed to risk analysis, where risk is conceptualized as the probability that capabilities are reduced. Capabilities refer to the genuine opportunities of individuals to achieve valuable doings and beings, such as being adequately nourished. Such doings and beings are called functionings. A current debate in risk analysis and other fields where a capability approach has been developed concerns whether capabilities or actual achieved functionings should be used. This paper argues that in risk analysis the consequences (...)

  17. A Strategy for Assessing Closure.Peter Murphy - 2006 - Erkenntnis 65 (3):365 - 383.
    This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument (...)

    The Defect in Effective Skeptical Scenarios.Peter Murphy - 2013 - International Journal for the Study of Skepticism 3 (4):271-281.
    What epistemic defect needs to show up in a skeptical scenario if it is to effectively target some belief? According to the false belief account, the targeted belief must be false in the skeptical scenario. According to the competing ignorance account, the targeted belief must fall short of being knowledge in the skeptical scenario. This paper argues for two claims. The first is that, contrary to what is often assumed, the ignorance account is superior to the false belief account. The (...)

    Molinism, Creature-Types, and the Nature of Counterfactual Implication.Daniel Murphy - 2012 - European Journal for Philosophy of Religion 4 (1):65-86.
    Granting that there could be true subjunctive conditionals of libertarian freedom (SCLs), I argue (roughly) that there could be such conditionals only in connection with individual "possible creatures" (in contrast to types). This implies that Molinism depends on the view that, prior to creation, God grasps possible creatures in their individuality. In making my case, I explore the notions of counterfactual implication (that relationship between antecedent and consequent of an SCL which consists in its truth) and counterfactual relevance (that feature (...)

  21. Another Blow to Knowledge From Knowledge.Peter Murphy - 2013 - Logos and Episteme 4 (3): 311–317.
    A novel argument is offered against the following popular condition on inferential knowledge: a person inferentially knows a conclusion only if they know each of the claims from which they essentially inferred that conclusion. The epistemology of conditional proof reveals that we sometimes come to know conditionals by inferring them from assumptions rather than beliefs. Since knowledge requires belief, cases of knowing via conditional proof refute the popular knowledge from knowledge condition. It also suggests more radical cases against the condition (...)

  22. Closure Failures for Safety.Peter Murphy - 2005 - Philosophia 33 (1-4):331-334.
    Ernest Sosa and others have proposed a safety condition on knowledge: If S knows p, then in the nearest (non-actual) worlds in which S believes p, p is true.1 Colloquially, this is the idea that knowing requires not being easily mistaken. Here, I will argue that like another condition requiring a counterfactual relation between a subject’s belief and the world, viz. Robert Nozick’s sensitivity condition, safety leads, in certain cases, to the unacceptable result that knowledge is not closed under known (...)

    This paper is about the nature of God’s pre-creation knowledge of possible creatures. I distinguish three theories: non-qualitative singularism, qualitative singularism, and qualitative generalism, which differ in terms of whether the relevant knowledge is qualitative or non-qualitative, and whether God has singular or merely general knowledge of creatures. My main aim is to argue that qualitative singularism does not depend on a version of the Principle of Identity of Indiscernibles to the effect that, necessarily, qualitatively indiscernible individuals are identical. It (...)

    Teaching Applied Ethics to the Righteous Mind.Peter Murphy - 2014 - Journal of Moral Education 43 (4):413-428.
    What does current empirically informed moral psychology imply about the goals that can be realistically achieved in college-level applied ethics courses? This paper takes up this question from the vantage point of Jonathan Haidt’s Social Intuitionist Model of human moral judgment. I summarize Haidt’s model, and then consider a variety of pedagogical goals. I begin with two of the loftiest goals of ethics education, and argue that neither is within realistic reach if Haidt’s model is correct. I then look at (...)

    This paper discusses the representation and explanation of relationships between phenomena that are important in psychiatric contexts. After a general discussion of complexity in the philosophy of science, I distinguish zooming-out approaches from zooming-in approaches. Zooming-out has to do with seeing complex mental illnesses as abstract models for the purposes of both explanation and reduction. Zooming-in involves breaking complex mental illnesses into simple components and trying to explain those components independently in terms of specific causes. Connections between existing practice and (...)

  26. Reliability Connections Between Conceivability and Inconceivability.Peter Murphy - 2006 - Dialectica 60 (2):195-205.
    Conceivability is an important source of our beliefs about what is possible; inconceivability is an important source of our beliefs about what is impossible. What are the connections between the reliability of these sources? If one is reliable, does it follow that the other is also reliable? The central contention of this paper is that suitably qualified the reliability of inconceivability implies the reliability of conceivability, but the reliability of conceivability fails to imply the reliability of inconceivability.

    Are Strong States Key to Reducing Violence? A Test of Pinker.Ryan Murphy - 2016 - Libertarian Papers 8:311-317.
    This note evaluates the claim of Steven Pinker in The Better Angels of Our Nature that the advent of strong states led to a decline in violence. I test this claim in the modern context, measuring the effect of the strength of government in lower-income countries on reductions in homicide rates. The strength of government is measured using Polity IV, Worldwide Governance Indicators, and government consumption as a percentage of GDP. The data do not support Pinker’s hypothesis.

  28. Rewriting the A Priori/A Posteriori Distinction.Peter Murphy - 2008 - Journal of Philosophical Research 33:279-284.
    The traditional way of drawing the a priori/a posteriori distinction, bequeathed to us by Kant, leads to overestimating the role that experience plays in justifying ourbeliefs. There is an irony in this: though Kant was in the rationalist camp, his way of drawing the distinction gives an unfair advantage to radical empiricism. I offer an alternative way of drawing the distinction, one that does not bias the rationalist/empiricist debate.

    In an earlier paper, I presented a novel objection to closure-based skeptical arguments. There I argued that the best account of what makes skeptical scenarios effective cripples the closure-based skeptical arguments that use those scenarios. On behalf of the skeptic, Christopher Buford and Anthony Brueckner have replied to my objection. Here I review my original argument, criticize their replies, and highlight two important issues for further investigation.

    As effective altruists often point out affluent people can do great good for others without having to make significant self-sacrifices. What is the correct moral assessment of patterns of giving that bring about great good and yet carry little in the way of self-sacrifice?

  31. A Sceptical Rejoinder to Sensitivity-Contextualism.Peter Murphy - 2005 - Dialogue 44 (4):693-706.
    This article offers a novel sceptical argument that the sensitivity-contextualist must say is sound; moreover, she must say that the conclusion of thisargument is true at ordinary standards. The view under scrutiny has it that in different contexts knowledge-attributing sentences express different propositions, propositions which differ in the stretch of worlds across which the subject is required to track the truth. I identify the underlying reason for the sceptical result and argue that it makes sensitivity-contextualism irremediably flawed. Contextualists, I conclude, (...)

    Avoiding the Dogmatic Commitments of Contextualism.Tim Black & Peter Murphy - 2005 - Grazer Philosophische Studien 69 (1):165-182.
    Epistemological contextualists maintain that the truth-conditions of sentences of the form 'S knows that P' vary according to the context in which they're uttered, where this variation is due to the semantics of 'knows'. Among the linguistic data that have been offered in support of contextualism are several everyday cases. We argue that these cases fail to support contextualism and that they instead support epistemological invariantism—the thesis that the truth-conditions of 'S knows that P' do not vary according to the (...)

From its humble beginnings at the Vienna Circle, the movement matured into a vibrant research program at Oslo, and sought adventure at Berkeley thereafter. The harsh and uncharitable reaction it met is surprising but understandable in light of disciplinary tensions and the legacy of antipsychologism—sentiments (...)

    The growing visibility of various forms of creationism in Northern Ireland raises issues for science education.

A sample of 112 pre-service science teachers answered a survey on attitudes toward evolution. Preliminary analysis revealed many of these new teachers held views contrary to scientific consensus—over one fifth doubt the evidence for human evolution, (...)
