Psychologism in logic is the doctrine that the semantic content of logical terms is in some way a feature of human psychology. We consider the historically influential version of the doctrine, Psychological Individualism, and the many counter-arguments to it. We then propose and assess various modifications to the doctrine that might allow it to avoid the classical objections. We call these Psychological Descriptivism, Teleological Cognitive Architecture, and Ideal Cognizers. These characterizations give some order to the wide range of modern views (...) that are seen as psychologistic because of one or another feature. Although these can avoid some of the classic objections to psychologism, some still hold. (shrink)

THINKER is an automated natural deduction first-order theorem proving program. This paper reports on how it was adapted so as to prove theorems in modal logic. The method employed is an indirect semantic method, obtained by considering the semantic conditions involved in being a valid argument in these modal logics. The method is extended from propositional modal logic to predicate modal logic, and issues concerning the domain of quantification and existence in a world's domain are discussed. Finally, we look at (...) the very interesting issues involved with adding identity to the theorem prover in the realm of modal predicate logic. Various alternatives are discussed. (shrink)

The Law of Non-Contradiction - that no contradiction can be true - has been a seemingly unassailable dogma since the work of Aristotle. It is an assumption challenged from a variety of angles in this collection of original papers. Twenty-three of the world's leading experts investigate the 'law', considering arguments for and against it and discuss methodological issues that arise. The result is a balanced inquiry into a venerable principle of logic, one that raises questions at the very centre of (...) logic itself. (shrink)

Defending Life is arguably the most comprehensive defense of the pro-life position on abortion - morally, legally, and politically - that has ever been published in an academic monograph. It offers a detailed and critical analysis of Roe v. Wade and Planned Parenthood v. Casey as well as arguments by those who defend a Rawlsian case for abortion-choice, such as J. J. Thomson. The author defends the substance view of persons as the view with the most explanatory power. The substance (...) view entails that the unborn is a subject of moral rights from conception. While defending this view, the author responds to the arguments of thinkers such as Boonin, Dworkin, Stretton, Ford and Brody. He also critiques Thomson's famous violinist argument and its revisions by Boonin and McDonagh. Defending Life includes chapters critiquing arguments found in popular politics and the controversy over cloning and stem cell research. (shrink)

Hans-Georg Gadamer and Paul Ricoeur were two of the most important hermeneutical philosophers of the twentieth century. Gadamer single-handedly revived hermeneutics as a philosophical field with his many essays and his masterpiece, Truth and Method. Ricoeur famously mediated the Gadamer-Habermas debate and advanced his own hermeneutical philosophy through a number of books addressing social theory, religion, psychoanalysis and political philosophy. This book brings Gadamer and Ricoeur into a hermeneutical conversation with each other through some of their most important commentators. Twelve (...) leading scholars deliver contemporary assessments of the history and promise of hermeneutical philosophy, providing focused discussion on the work of these two key hermeneutical thinkers. The book shows how the horizons of their thought at once support and question each other and how, in many ways, the work of these two pioneering philosophers defines the issues and agendas for the new century.

The purpose of this essay is to offer support for the substance view of persons, the philosophical anthropology defended by Patrick Lee in his essay. In order to accomplish this the author presents a brief definition of the substance view; argues that the substance view has more explanatory power in accounting for why we believe that human persons are intrinsically valuable even when they are not functioning as such, why human persons remain identical to themselves over time, and why it (...) follows from these points that the unborn are human persons; and responds to two arguments that attempt to establish the claim that the early human being is not a unified substance until at least fourteen days after conception.

Catholics and Evangelical Protestants often find themselves on the same side on a variety of issues in bioethics. However, some Evangelicals have expressed reluctance to embrace the natural law reasoning used by Catholics in academic and policy debates. In this article, I argue that the primary concerns raised by Evangelicals about natural law reasoning are, ironically, concerns expressed by and intrinsic to the natural law tradition itself. To show this, I address two types of Protestant critics: the Frustrated Fellow Traveler (...) and the Solo Scripturist. (shrink)

This article responds to Giubilini and Minerva’s article ‘After birth abortion: why should the baby live?’ published in the Journal of Medical Ethics. They argue for the permissibility of ‘after-birth abortion’, based on two conjoined considerations: (1) the fetus or newborn, though a ‘potential person’, is not an actual person, because it is not mature enough to appreciate its own interests, and (2) because we allow parents to terminate the life of a fetus when it is diagnosed with a deformity (...) or fatal illness because of the burden it will place on the child, parent, family or society we should also allow parents to do the same to their newborn, since it is no more a person than the fetus. The author critiques this case by pointing out (a) the metaphysical ambiguity of potential personhood and (b) why the appeal to burdens is irrelevant or unnecessary. (shrink)

This book is an extended argument for the critical importance which justice and ethical leadership should have in business ethics education. The book examines the history of ideas and purposes in education, the contemporary role of business schools, and the social foundations of moral education to conclude that the pragmatic pursuit of the good must be a central aim of business strategy. To meet the challenges of facing society today, the masters of business must be moral craftsmen in a just (...) and democratic private property economy that serves the common good. The author grounds this vision for business leadership in the centrality of systems of exchange in human society, in generating prosperity and providing for the general welfare. Business ethics education has focused primarily on moral formation of individual leaders and managers in the context of ethical codes, organizational culture, and legal compliance. Important as this approach is, it fails to generate a sufficient level of business responsibility to satisfy legitimate social concerns regarding the use of natural resources, environmental sustainability, reasonable limitation of systemic risk in capital markets, and fair allocation of goods and services. If the social purpose of business is not intentionally embraced and diligently pursued, the economy may enrich a few but impoverish the society, its resources, and its democracy. Hence this book argues for a new vision of business ethics that is grounded in public accountability of business operations and outcomes for the common good, as a matter of justice. (shrink)

The Hungarian-born author, who is both an original and a prolific thinker, has written on various figures of the history of philosophy and on particular philosophic problems, his first published work having been his Grundlegung der Philosophie, followed by studies in metaphysics,; esthetics, psychology, and philosophic anthropology. However, the major work containing his own system is the Aufbau des Seins. To know and under stand Brandenstein's philosophy, one ought to study this work, a task made difficult by its coined terms, (...) its complicated, Ciceronian style, the relative novelty of its thought, and its extreme systematization.
