The promises of precision medicine are often heralded in the medical and lay literature, but routine integration of genomics in clinical practice is still limited. While the “last mile” infrastructure to bring genomics to the bedside has been demonstrated in some healthcare settings, a number of challenges remain — both in the receptivity of today's health system and in its technical and educational readiness to respond to this evolution in care. To improve the impact of genomics on health and disease (...) management, we will need to integrate both new knowledge and new care processes into existing workflows. This change will be onerous and time-consuming, but hopefully valuable to the provision of high quality, economically feasible care worldwide. (shrink)

This paper provides an analysis of contrary-to-duty reasoning from the proof-theoretical perspective of category theory. While Chisholm’s paradox hints at the need of dyadic deontic logic by showing that monadic deontic logics are not able to adequately model conditional obligations and contrary-to-duties, other arguments can be objected to dyadic approaches in favor of non-monotonic foundations. We show that all these objections can be answered at one fell swoop by modeling conditional obligations within a deductive system defined as an instance of (...) a symmetric monoidal closed category. Using category theory as a foundational framework for logic, we show that it is possible to model conditional normative reasoning and conflicting obligations within a monadic approach without adding further operators or considering deontic conditionals as primitive.

Monoidal logics were introduced as a foundational framework to analyse the proof theory of deontic logic. Building on Lambek’s work in categorical logic, logical systems are defined as deductive systems, that is, as collections of equivalence classes of proofs satisfying specific rules and axiom schemata. This approach enables the classification of deductive systems with respect to their categorical structure. When looking at their proof theory, however, one can see that there are similarities between monoidal and substructural logics. The purpose of (...) the present paper is to address this issue and highlight the differences between these two approaches. We argue that monoidal logics provide a more flexible foundational framework that enables a finer analysis of the relationship between negation and other logical connectives. We show that the elimination of double negation is independent from the de Morgan dualities, that monoidal deductive systems are not necessarily weakly distributive and that deduc... (shrink)

In psychology, measurement instruments are constructed from scales, which are obtained on the grounds of exploratory and confirmatory factor analysis. Looking at the literature, one can find various recommendations regarding how these techniques should be used during the scale construction process. Some authors suggest to use exploratory factor analysis on the entire data set while others advice to perform an internal cross-validation by randomly splitting the data set in two and then either perform exploratory factor analysis on both parts or (...) exploratory factor analysis on the first part and confirmatory factor analysis on the other. In spite of all these divergent recommendations, there is no consensus on which method yields the best result. In this paper, we analyze this issue in light of the prediction versus accommodation debate and argue that the answer to this question depends on one’s conception of the criteria that should be used to achieve the goals of the scientific enterprise.

Realism is generally assumed as the correct position with regards to psychological research and the measurement of psychological attributes in psychometrics. Borsboom et al., 203–219 2003), for instance, argued that the choice of a reflective measurement model necessarily implies a commitment to the existence of psychological constructs as well as a commitment to the belief that empirical testing of measurement models can justify their correspondence with real causal structures. Hood :739–761 2013) deemphasized Borsboom et al.’s position and argued that the (...) choice of a reflective measurement model does not necessarily require ontological commitments, though, in his view, it does necessitate a commitment to minimal epistemic realism. Although these arguments are formulated with regard to psychological research, they can actually be generalized to other disciplines in social sciences that use similar methodologies and statistical techniques. In Hood’s opinion, empiricism does not suffice to provide an adequate account of the choice of reflective measurement models given that this choice requires an appeal to causal explanations. In this paper, we argue against Hood and answer this challenge, providing epistemic foundations for social science research that do not appeal to realism. (shrink)

Exploratory factor analysis is a statistical method widely used in quantitative psychology for the construction of scales and measurement instruments. It aims to reduce the complexity of a data set and explain the common and unique variance using latent variables. In introductory textbooks, exploratory factor analysis is generally presented in contrast to confirmatory factor analysis as a theory- or a hypothesis-generating process that does not require prior background, theory or hypothesis to be performed. The aim of the present paper is (...) to analyze this claim and clarify in which sense exploratory factor analysis is theory-laden. We provide a careful examination of the concepts it involves and thereby establish a clear limitation of the epistemic scope of exploratory factor analysis. (shrink)

In this paper, we argue that Forrester’s paradox, as he presents it, is not a paradox of standard deontic logic. We show that the paradox fails since it is the result of a misuse of , a derived rule in the standard systems. Before presenting Forrester’s argument against standard deontic logic, we will briefly expose the principal characteristics of a standard system Δ. The modal system KD will be taken as a representative. We will then make some remarks regarding , (...) pointing out that its use is restricted to the standard system’s theorems, and cannot be applied to contingent conditionals. Finally, we will show that Forrester’s paradox is not a paradox of standard deontic logic, at least not in the sense he intended it to be. We show that the paradox cannot arise in KD since its semantical model is not rich enough to represent the intuitive validity of the conditional within Forrester’s paradox. We show that the paradox arises within a system that has a finer semantics. (shrink)

Ce texte se veut une analyse critique de l'approche de Thomason quant à la logique déontique. Alors que l'auteur défend que celle-ci doit être formalisée dans le cadre des logiques temporelles, nous soutenons que la temporalité est implicite à l'obligation, et de fait que la logique déontique n'a pas a être traitée dans la cadre d'une logique temporelle. Nous présenterons d'abord la position de Thomason. Il sera question des exemples dont l'auteur se sert pour justifier son point de vue philosophique (...) et du modèle sémantique qu'il propose pour rendre compte de l'obligation. Il sera ensuite sujet d'une critique des exemples de l'auteur et de son modèle sémantique. (shrink)

Cet article se veut une critique de la thèse défendue par [Cleland 1993], laquelle soutient que la thèse de Church doit être rejetée puisque les limites du calcul dépendent de la structure physique du monde.

Par la suite, nous proposons une analyse critique de son argument, ce qui nous amènera à faire quelques distinctions conceptuelles par rapport aux notions (...) qui concernent la calculabilité. Finalement, nous montrons que les limites du calcul ne sont pas physiques mais bien logiques. En résumé, notre argument est que les limites du calcul sont déterminées en partie par le fait qu’une procédure effective doit pouvoir être décrite de manière finie. (shrink)

In this paper, we argue against the position of [Cleland 1993], which defends that Church s thesis must be rejected because the limits of computation depend upon the physical structure of the world. We first give a brief overview of Church’s thesis and then we present Cleland s argument. We then propose a critical analysis of Cleland s argu­ment, which will involve some conceptual distinctions regarding the notion of computability, and finally we will show that the limits of computation are not physical but logical. In short, we argue that computation is limited by the fact that an effective procedure must be described in a finite way. (shrink)

This research article revisits Hempel’s logic of confirmation in light of recent developments in categorical proof theory. While Hempel advocated several logical conditions in favor of a purely syntactical definition of a general non-quantitative concept of confirmation, we show how these criteria can be associated to specific logical properties of monoidal modal deductive systems. In addition, we show that many problems in confirmation logic, such as the tacked disjunction, the problem of weakening with background knowledge and the problem of irrelevant (...) conjunction, are also associated with specific logical properties and, incidentally, with some of Hempel’s logical conditions of adequacy. We discuss the raven paradox together with further objections against Hempel’s approach, showing how our analysis enables a clear understanding of the relationships between Hempel’s conditions, the problems in confirmation logic, and the properties of deductive systems.

Philip Clayton has put forth a clear and important position regarding the mind-body relationship in terms of supervenient and emergent realities. While I agree with Clayton on many points, I argue that there are important problems with current literature on supervenience and emergence. In particular, I distinguish between closed system emergence and open system emergence, suggesting that Clayton’s position is closer to the latter than the former.

Nicholaos Jones argues that theology is not a respectable discipline because of its inability to meet the standards of contemporary science. Although Jones makes a bold claim, I suggest that he has not made his case by focusing on the question of defining science and metaphysics appropriately, the analysis of the literature he cites, and his central claim that theology presupposes the absolute certainty of God.

This brief opening for a special issue of Tradition and Discovery: The Polanyi Society Periodical on Philip Clayton’s thought and its connection with that of Michael Polany introduces Clayton’s essay and the responses by Martinez Hewlett, Gregory R. Peterson, Andy F. Sanders and Waler B. Gulick.

American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict or (...) come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)

This excellent anthology in the philosophy of religion examines the basic classical and a host of contemporary issues in thirteen thematic sections. Assuming little or no familiarity with the religious concepts it addresses, it provides a well-balanced and accessible approach to the field. The articles cover the standard topics in the field, including religious experience, theistic arguments, the problem of evil, and miracles, as well as topics that have gained the attention of philosophers of religion in the last fifteen years, (...) such as reformed epistemology, the philosophical analysis of theological doctrine, and the kalam theological argument. The collection also includes topics often requested by instructors but seldom covered in competing texts, such as religion and science, religious pluralism, process theism, and religious ethics, offering greater flexibility in choosing exact topics for use in courses. The format of the book makes it an ideal teaching text, as each section begins with a brief introduction to the central topic or issue treated by the readings which follow. Each reading is preceded by a one paragraph summary, and a bibliography of suggested readings follow each section. Philosophy of Religion functions well as a stand-alone textbook for courses in the philosophy of religion, and is readily compatible for use as a primary source reader in conjunction with a secondary text. It is an ideal companion to Reason and Religious Belief, 2e (OUP, 1997). (shrink)

What does everyone in the modern world need to know? Renowned psychologist Jordan B. Peterson's answer to this most difficult of questions uniquely combines the hard-won truths of ancient tradition with the stunning revelations of cutting-edge scientific research. Humorous, surprising and informative, Dr. Peterson tells us why skateboarding boys and girls must be left alone, what terrible fate awaits those who criticize too easily, and why you should always pet a cat when you meet one on the street. (...) What does the nervous system of the lowly lobster have to tell us about standing up straight (with our shoulders back) and about success in life? Why did ancient Egyptians worship the capacity to pay careful attention as the highest of gods? What dreadful paths do people tread when they become resentful, arrogant and vengeful? Dr. Peterson journeys broadly, discussing discipline, freedom, adventure and responsibility, distilling the world's wisdom into 12 practical and profound rules for life. [This book] shatters the modern commonplaces of science, faith and human nature, while transforming and ennobling the mind and spirit of its readers. (shrink)

Must rational thinkers have consistent sets of beliefs? I shall argue that it can be rational for a thinker to believe a set of propositions known to be inconsistent. If this is right, an important test for a theory of rational belief is that it allows for the right kinds of inconsistency. One problem we face in trying to resolve disagreements about putative rational requirements is that parties to the disagreement might be working with different conceptions of the relevant attitudes. (...) My aim is modest. I hope to show that there is at least one important notion of belief such that a thinker might rationally hold a collection of beliefs (so understood) even when the thinker knows their contents entail a contradiction.

Crockett develops a constructive radical theology from the philosophy of Kant. Reading The Critique of Judgment back into The Critique of Pure Reason, Crockett draws upon the insights of such continental philosophers as Heidegger, Derrida, Lyotard and Deleuze. This book shows how existential notions of self, time and imagination are interrelated in Kantian thinking, and demonstrates their importance for theology. An original theology of the sublime emerges as a connection is made between the Kantian sublime of the Third Critique and (...) the transcendental imagination of the First Critique. (shrink)

The internalism-externalism debate is one of the oldest debates in epistemology. Internalists assert that the justification of our beliefs can only depend on facts internal to us, while externalists insist that justification can depend on additional, for example environmental, factors. Clayton Littlejohn proposes and defends a new strategy for resolving this debate. Focussing on the connections between practical and theoretical reason, he explores the question of whether the priority of the good to the right might be used to defend (...) an epistemological version of consequentialism, and proceeds to formulate a new 'deontological externalist' view. On this view, the justificatory status of a belief depends upon whether it is fit for the purposes of practical reasoning. Only beliefs that meet externalist standards are fit for such a purpose. If we want to understand how a wide range of norms (e.g., moral norms) apply to rational agents regardless of what their evidence or outlook is like, we have to embrace an externalist account of the justification.

A questão relacionada ao método, na obra de Michel Foucault, é uma problemática na qual alguns pesquisadores têm se debruçado, tendo em vista a diversidade dos caminhos de pesquisa trilhados ao longo de sua produção intelectual. Nesse sentido, o presente estudo, através de uma discussão teórica, pretende colocar em pauta o conceito de anarqueologia, desenvolvido pelo filósofo francês no curso Do governo dos vivos, de 1980. A hipótese que se pretende desdobrar é a de que o conceito em voga se (...) inscreve em um percurso teórico-metodológico particular, abarcando um encadeamento dos três domínios ou eixos (ser-saber, ser-poder, ser-consigo) da obra de Foucault, viabilizando assim certa reformulação da interpretação foucaultiana acerca do sujeito.

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

In this work, Clayton Crockett rehabilitates Deleuze's position within contemporary political and philosophical thought, advancing an original reading of the thinker's major works and a constructive conception of his philosophical ontology.

Clayton Crockett and Jeffrey Robbins describe a number of the intellectual developments and movements that preceded and influenced radical theology. They pay special attention to the hermeneutics of suspicion of Feuerbach, Marx, Freud, and Nietzsche; the phenomenology of Husserl, Heidegger, and Merleau-Ponty; and the linguistic structuralism of Saussure. Crockett and Robbins pay close attention to the role of Derrida’s lecture, “Structure, Sign, and Play in the Discourse of the Human Sciences,” in 1966 before moving on to the Death of (...) God movement. They emphasize the way Tillich’s thought was radicalized by G. Vahanian, Altizer, Daly, and others in combination with Tillich’s theology of culture and existential theology and Bonhoeffer’s influence on the early Death of God thinkers. Finally, Crockett and Robbins discuss radical theology’s hybridization with deconstruction in the work of Raschke, Mark C. Taylor, and Winquist and hybridizing RT with deconstruction. (shrink)

Two interpretations of the precautionary principle are considered. According to the normative interpretation, the precautionary principle should be characterised in terms of what it urges doctors and other decision makers to do. According to the epistemic interpretation, the precautionary principle should be characterised in terms of what it urges us to believe. This paper recommends against the use of the precautionary principle as a decision rule in medical decision making, based on an impossibility theorem presented in Peterson . However, (...) the main point of the paper is an argument to the effect that decision theoretical problems associated with the precautionary principle can be overcome by paying greater attention to its epistemic dimension. Three epistemic principles inherent in a precautionary approach to medical risk analysis are characterised and defended. (shrink)

In A World Not Made for Us, Keith R. Peterson provides a broad reassessment of the field of environmental philosophy, taking a fresh and critical look at three classical problems of environmentalism: the intrinsic value of nature, the need for an ecological worldview, and a new conception of the place of humankind in nature. Peterson makes the case that a genuinely critical environmental philosophy must adopt an ecological materialist conception of the human, a pluralistic value theory that emphasizes (...) the need for value prioritization, and a stratified categorical ontology that affirms the basic principle of human asymmetrical dependence on more-than-human nature. Integrating environmental ethics with the latest work in political ecology, Peterson argues it is important to understanding that the world is not made for us, and that coming to terms with this fact is a condition for survival in future human and more-than-human communities of liberation and solidarity.
