Modal epistemologists parse modal conditions on knowledge in terms of metaphysical possibilities or ways the world might have been. This is problematic. Understanding modal conditions on knowledge this way has made modal epistemology, as currently worked out, unable to account for epistemic luck in the case of necessary truths, and unable to characterise widely discussed issues such as the problem of religious diversity and the perceived epistemological problem with knowledge of abstract objects. Moreover, there is reason to think that this (...) is a congenital defect of orthodox modal epistemology. This way of characterising modal epistemology is however optional. It is shown that one can non-circularly characterise modal conditions on knowledge in terms of epistemic possibilities, or ways the world might be for the target agent. Characterising the anti-luck condition in terms of epistemic possibilities removes the impediment to understanding epistemic luck in the case of necessary truths and opens the door to using these conditions to shed new light on some longstanding epistemological problems.

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic inferentialism, as it is developed by Brandom, then Plantinga's motivation for the (...) evolutionary argument against naturalism is undermined. (shrink)

Modal ontological arguments argue from the possible existence of a perfect being to the actual (necessary) existence of a perfect being. But modal ontological arguments have a problem of symmetry; they can be run in both directions. Reverse ontological arguments argue from the possible nonexistence of a perfect being to the actual (necessary) nonexistence of a perfect being. Some familiar points about the necessary a posteriori, however, show that the symmetry can be broken in favour of the ontological argument.

Within contemporary philosophy of mind, it is taken for granted that externalist accounts of meaning and mental content are, in principle, orthogonal to the matter of whether cognition itself is bound within the biological brain or whether it can constitutively include parts of the world. Accordingly, Clark and Chalmers (1998) distinguish these varieties of externalism as ‘passive’ and ‘active’ respectively. The aim here is to suggest that we should resist the received way of thinking about these dividing lines. With reference (...) to Brandom’s (1994; 2000; 2008) broad semantic inferentialism, we show that a theory of meaning can be at the same time a variety of active externalism. While we grant that supporters of other varieties of content externalism (e.g., Putnam 1975 and Burge 1986) can deny active externalism, this is not an option for semantic inferentialists: On this latter view, the role of the environment (both in its social and natural form) is not ‘passive’ in the sense assumed by the alternative approaches to content externalism.

We offer an alternative to two influential accounts of virtue epistemology: Robust Virtue Epistemology and Anti-Luck Virtue Epistemology. We argue that while traditional RVE does offer an explanation of the distinctive value of knowledge, it is unable to effectively deal with cases of epistemic luck; and while ALVE does effectively deal with cases of epistemic luck, it lacks RVE’s resources to account for the distinctive value of knowledge. The account we provide, however, is both robustly virtue-theoretic and anti-luck, having the (...) respective benefits of both rival accounts without their respective shortcomings. We describe this view here. (shrink)

Despite its intrinsic plausibility, the sensitivity principle has remained deeply unpopular on the grounds that it violates an even more plausible closure principle. Here we show that sensitivity does not, in general, violate closure. Sensitivity only violates closure when combined with further auxiliary premises—regarding which of an agent’s commitments constitute that agent’s beliefs—which are optional for the sensitivity theorist.

In Romans 5, St. Paul claims that death came into the world through Adam's sin. Many have taken this to foist on us a fundamentalist reading of Genesis. If death is the result of human sin, then, apparently, there cannot have been death in the world prior to human sin. This, however, is inconsistent with contemporary evolutionary biology, which requires that death predates the existence of modern humans. Although the relationship between Romans 5, Genesis, and contemporary science has been much (...) discussed—often with goal of dissipating the idea that the two are in conflict—the specific issue of death entering the world through sin has remained difficult to resolve. I argue that the Eastern Orthodox tradition has the resources to respect both Romans 5 and contemporary science. Appealing to a broadly Irenaean notion of soul‐making, and to the idea of theosis, opens up space for an understanding of these passages that is both scientifically informed and Orthodox. (shrink)

Mathematical Nominalism Mathematical nominalism can be described as the view that mathematical entities—entities such as numbers, sets, functions, and groups—do not exist. However, stating the view requires some care. Though the opposing view (that mathematical objects do exist) may seem like a somewhat exotic metaphysical claim, it is usually motivated by the thought that mathematical … Continue reading Mathematical Nominalism →.

Introduction: I lay out the broad contours of my thesis: a defence of mathematical nominalism, and nominalism more generally. I discuss the possibility of metaphysics, and the relationship of nominalism to naturalism and pragmatism. Chapter 2: I delineate an account of abstractness. I then provide counter-arguments to claims that mathematical objects make a di erence to the concrete world, and claim that mathematical objects are abstract in the sense delineated. Chapter 3: I argue that the epistemological problem with abstract objects (...) is not best understood as an incompatibility with a causal theory of knowledge, or as an inability to explain the reliability of our mathematical beliefs, but resides in the epistemic luck that would infect any belief about abstract objects. To this end, I develop an account of epistemic luck that can account for cases of belief in necessary truths and apply it to the mathematical case. Chapter 4: I consider objections, based on metaphysical considerations and linguistic data, to the view that the existential quantifier expresses existence. I argue that these considerations can be accommodated by an existentially committing quantifier when the pragmatics of quantified sentences are properly understood. I develop a semi-formal framework within which we can define a notion of nominalistic adequacy. I show how our notion of nominalistic adequacy can show why it is legitimate for the nominalist to make use of platonistic “assumptions” in inference-making. Chapter 5: I turn to the application of mathematics in science, including explanatory applications, and its relation to a number of indispensability arguments. I consider also issues of realism and anti-realism, and their relation to these arguments. I argue that abstraction away from pragmatic considerations has acted to skew the debate, and has obscured possibilities for a nominalistic understanding of mathematical practices. I end by explaining the notion of a pragmatic meta-vocabulary, and argue that this notion can be used to carve out a new way of locating our ontological commitments. Chapter 6: I show how the apparatus developed in earlier chapters can be utilised to roll out the nominalist project to other domains of discourse. In particular, I consider propositions and types. I claim that a unified account of nominalism across these domains is available. Conclusion: I recapitulate the claims of my thesis. I suggest that the goal of mathematical enquiry is not descriptive knowledge, but understanding. (shrink)

The semantic inferentialist account of the social institution of semantic meaning can be naturally extended to account for social ontology. I argue here that semantic inferentialism provides a framework within which mathematical ontology can be understood as social ontology, and mathematical facts as socially instituted facts. I argue further that the semantic inferentialist framework provides resources to underpin at least some aspects of the objectivity of mathematics, even when the truth of mathematical claims is understood as socially instituted.

We provide a translation of Binet and Henri’s pioneering 1894 paper on the influence of suggestibility on memory. Alfred Binet is famous as the author who created the IQ test that bears his name, but he is almost unknown as the psychological investigator who generated numerous original experiments and fascinating results in the study of memory. His experiments published in 1894 manipulated suggestibility in several ways to determine effects on remembering. Three particular modes of suggestion were employed to induce false (...) recognitions: indirect suggestion by a preconceived idea; direct suggestion; and collective suggestion. In the commentary we suggest that Binet and Henri’s paper written over 115 years ago is still highly relevant even today. In particular, Binet’s legacy lives on in modern research on misinformation effects in memory, in studies of conformity, and in experiments on the social contagion of memory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Foundation of Ethical Theory in the ClinicJohn Collins Harvey (bio)William Osler has had a very profound and lasting effect on American medical education and medical practice. He set the pattern, still followed today, for the clinical training of medical students at the patient’s bedside and in the clinical laboratory. In such settings Osler was able to demonstrate to his pupils the principles, ethics, and standards of medical practice (...) that he espoused and thought fundamental to the profession of medicine. His monumental text book, The Principles and Practice of Medicine, first published in 1892, transformed the medical profession and remained a standard text for more than four decades (Leon 1995, p. 13). Renowned medical historians, such as Pedro Laín Entralgo, Henry Sigerist, and Richard Shyrock, recognize him as the greatest clinician that North America has ever produced.Osler, who had observed bedside teaching in his post-graduate studies, recognized that this method had much to offer in the instruction of medical students. Opportunity to introduce this method of teaching into the medical school curriculum came in 1888 when he was called to serve as Professor of Medicine and Physician-in-Chief at the newly established Johns Hopkins Medical School and Hospital. Bedside teaching proved to be very successful especially in demonstrating to students the standards and ethics of medical practice that he espoused.Osler’s teaching method was immediately adopted by many of the university medical schools in the United States, including Harvard, Columbia, the University of Pennsylvania, and Stanford, all of whom appreciated the success of the Hopkins medical educational experiment. Graduates of the Hopkins Medical School quickly became a major source of faculty in medical schools in the United States. Many of Osler’s immediate pupils became outstanding clinicians and leaders in American academic medicine and served as faculty members at Hopkins or in established or newly founded schools. Osler’s disciples taught students in the wards the “art” of medicine according to his principles, ethics, and standards. The second and third generation faculty members, who were trained by Osler’s immediate pupils, continue to this day to teach the “art” by employing this method of teaching. Consequently, the practice of medicine in the United States continues to be influenced by the ethics held by Osler. To find [End Page 343] the theories behind Osler’s teaching, we must look at Osler’s background, education, and writings.The Religio Medici: Background For Osler’S Medical EthicsOsler received a very solid traditional classical education at the small, excellent Anglican secondary school in Weston, Ontario run by the Reverend James Johnson, with whom Osler developed a life long friendship. Johnson’s avocation was natural science. He first aroused Osler’s interest in nature and science. Osler was taught Scripture well at Weston. He committed much of the Bible to memory and often quoted it in his speeches. He also studied both Greek and Latin, and was exposed to the writings of Plato, Aristotle, Cicero, and other classical authors, particularly the stoics.While a student at Weston, Osler first came to know Sir Thomas Browne’s remarkable text Religio Medici (The Religion of the Physician), which was to become a lifelong favorite. In his first address as the new Regius Professor of Medicine at Oxford in 1905, which was given to the Guy’s Hospital Physical Society, he vigorously recommended the Religio Medici to the students.The Religio is a deeply reflective personal inquiry into the paradoxical nature of one man as a microcosm of all men (Browne 1940, pp. 40, 53–54, 61–62). Browne participated in the Baconian program for the advancement of knowledge and the rise of “science.” As a defense of the physician’s faith, the Religio shows how neatly the scientist and the Christian united in the single figure of the inspired reader of God’s two books, nature and Scripture, can defend an attitude that is both scientific and yet reverent. The central theme in the first and much longer part of the Religio is the relation between faith and reason. The second part of the Religio is about charity: Man’s love of God and his neighbors, commanded as... (shrink)

When read alongside the great command of Deuteronomy, ‘love the Lord your God with all your heart, mind, and strength,’ the Judeo-Christian directive to ‘love your neighbour as yourself’ is perhaps one of the most theologically and ethically charged phrases in the Bible. In these two mutually reliant commandments lies a meeting point between the divine and the human that has important implications for our understanding of the nexus between theological conceptions of love and philosophical engagement with worldly existence. This (...) point of intersection is explored in a particularly unique way in the thinking of Michel Henry and Jean-Luc Nancy. In this article, I conduct the first sustained comparative analysis of their respective philosophies, using an exploration of the role of love and affectivity in their work to better understand the philosophical opportunity represented by the commandment to love God and neighbour.

In “The Search for Environmental Rights,” Joseph Sax argues that each individual should have, as a right, freedom from environmental hazards and access to environmental benefits, but he makes clear that environmental rights do not exist and their recognition would truly be a novel step. Sax states that environmental rights are different from existing human rights and argues that the closest analogy is welfare interests. In arguing for environmental rights, I follow Sax’s direction and draw from the work of those (...) who are the most relevant in establishing environmental rights. I consider Joel Feinberg’s notion of welfare interests, Henry Shue’s notion of basic rights, and James Nickel’s right to a safe environment. I draw from Mill’s harm principle, the superfund legislation, and the Clean Air Act to illustrate the existing ethical and legal bases for establishing environmental rights. Finally, I discuss positive and negative duties that such rights might carry. (shrink)

I respond to the reviews by Henry and Lowney of my book Tacit and Explicit Knowledge. I stress the need to understand explicit knowledge if tacit knowledge is to be understood. Tacit knowledge must be divided into three kinds: relational, somatic and collective. The idea of relational tacit knowledge is keyto pulling the three kinds apart.

The term "humanism" bears many meanings. The origin of its usage is associated with the Renaissance, but it can also be predicated on the thought of earlier and later generations. The most general purpose of this paper is to suggest the inevitable reliance of an array of meanings of "humanism" upon philosophical categories. To support this thesis, the author attempts to clarify some fundamental differences between the philosophical humanisms of Auguste Comte [1798-1957] and Blaise Pascal [1623-1662]. For purposes of expansion (...) and clarification, Comte is associated with John Dewey [1859-1952] and Pascal with John Henry Newman [1801-1890]. In conclusion, brief attention is given to some contrasting educational implications and to some applications to the recent past. (shrink)

Harry Collins’ book Tacit and Explicit Knowledge seeks to clarify the concept of tacit knowledge made famous by Michael Polanyi. Collins’ tripartite taxonomy of tacit knowledge is explained using illustrative examples from clinical medicine. Collins focuses on distinguishing the kinds of tacit knowledge that can (in principle) be made wholly explicit from the kinds of tacit knowledge that are inescapably tacit. Polanyi’s writings, on the other hand, emphasize the process of tacit knowing. Collins’ investigation of tacit knowledge makes an important (...) scholarly contribution that is distinct from and complementary to investigations that focus on tacit knowing. (shrink)

In their book, Roman but Not Catholic, Kenneth Collins and Jerry Walls make the case that certain beliefs central to the Roman Catholic faith are unreasonable. This article evaluates, from the point of view of Eastern Orthodoxy, some of the arguments Collins and Walls make. In particular, it argues first that Collins and Walls are correct to criticize John Henry Newman’s theory of the development of doctrine as a reason to accept otherwise insufficiently supported Catholic doctrines. Secondly, it offers (...) some points of clarification concerning the matter of sacred tradition and attempts to show the areas of agreement and disagreement between Eastern Orthodoxy and the position that Collins and Walls articulate. Thirdly, it argues that Collins and Walls rely on what is, from an Eastern Orthodox point of view, a questionable view about the interpretation of scripture by assuming without good reason that the clear meaning of scripture is equivalent to the literal interpretation.

A prominent approach to scientific explanation and modeling claims that for a model to provide an explanation it must accurately represent at least some of the actual causes in the event's causal history. In this paper, I argue that many optimality explanations present a serious challenge to this causal approach. I contend that many optimality models provide highly idealized equilibrium explanations that do not accurately represent the causes of their target system. Furthermore, in many contexts, it is in virtue of (...) their independence of causes that optimality models are able to provide a better explanation than competing causal models. Consequently, our account of explanation and modeling must expand beyond the causal approach. (shrink)

Many accounts of scientific modelling assume that models can be decomposed into the contributions made by their accurate and inaccurate parts. These accounts then argue that the inaccurate parts of the model can be justified by distorting only what is irrelevant. In this paper, I argue that this decompositional strategy requires three assumptions that are not typically met by our best scientific models. In response, I propose an alternative view in which idealized models are characterized as holistically distorted representations that (...) are justified by allowing for the application of various modelling techniques.
