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.

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.

The author argues that the fourth-century philosophers used protreptic discourses to market philosophical practices and to define and legitimize the school of higher learning.

This introductory overview of Kierkegaard's writings summarizes their central arguments and places them in their historical context. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions.

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)

Collins examines the main philosophical approaches taken toward God since the beginning of the fifteenth century, showing the often decisive role God's existence played in development of modern philosophy. Included are such diverse thinkers as Bruno, Leibniz, Voltaire, Marx, Heidegger, and Whitehead.

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)

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.

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)

James Collins probes the meaning and methods of historical interpretation in philosophy by analyzing the creative reciprocity between the modern source thinkers—the great classical philosophers from Descartes and Locke to Mill and Nietzsche—and their midtwentieth century interpreters.

Logic is the study of the validity of arguments, which is to say the study of when a conclusion follows or does not follow from a set of premises. Logic is an ancient discipline pioneered by Aristotle and developed by some of the greatest thinkers in the Middle Ages. However, in the nineteenth century logic underwent a remarkable transformation into a precise branch of mathematics that changed the nature of logic, and the study of religion, forever. Both religious adherents and (...) critics of religion have sometimes claimed that logic and religion do not mix, but this is a puzzling claim since logic itself is not a set of substantive premises about the world which may come into conflict with religious claims, but a means of testing mathematically which premises come into conflict with which other premises. In fact, sense can be made of whether logic and religion mix, but the question, and the answer, turn out to be more complex than many have thought. (shrink)

Collins’ method is to make an internal textual study of Spinoza’s doctrine on nature with emphasis on his general model of nature that underlies and gov­erns his arguments on particular issues. Separate chapters are devoted to each of his early writings. Two chapters discuss the _Ethics. _Collins concludes with a uni­fying view of Spinoza’s perspective on nature that has a bearing upon many contemporary philosophical issues.

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.

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 →.

Ecological research and conservation practice frequently raise difficult and varied ethical questions for scientific investigators and managers, including duties to public welfare, nonhuman individuals (i.e., animals and plants), populations, and ecosystems. The field of environmental ethics has contributed much to the understanding of general duties and values to nature, but it has not developed the resources to address the diverse and often unique practical concerns of ecological researchers and managers in the field, lab, and conservation facility. The emerging field of (...) “ecological ethics” is a practical or scientific ethics that offers a superior approach to the ethical dilemmas of the ecologist and conservation manager. Even though ecological ethics necessarily draws from the principles and commitments of mainstream environmental ethics, it is normatively pluralistic, including as well the frameworks of animal, research, and professional ethics. It is also methodologically pragmatic, focused on the practical problems of researchers and managers and informed by these problems in turn. The ecological ethics model offers environmental scientists and practitioners a useful analytical tool for identifying, clarifying, and harmonizing values and positions in challenging ecological research and management situations. Just as bioethics provides a critical intellectual and problem-solving service to the biomedical community, ecological ethics can help inform and improve ethical decision making in the ecology and conservation communities.
