Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the (...) circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals? perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:KARL RAHNER'S EXISTENTIAL ETIDCS: A CRITIQUE BASED ON ST. THOMAS'S UNDERSTANDING OF PRUDENCE I KARL RAHNER'S THEORY of a "formal existential ethics," which he proposes as a necessary supplement to the "essential ethics" of the Thomistic naturallaw tradition, has been both praised as a brilliant adaptation of the tradition to contemporary philosophy as well as criticised as a misleading and unnecessary break with Thomism. William A. Wailace, one (...) of the critics, characterizes Rahner's ethics as an unfortunate combination of mysticism and casuistry.1 Personal moral decision-making, according to Wallace, should depend on the virtue of prudence plus " gifts of grace" instead of on a theory of private spiritual discernment. A genuine Thomism in his view already achieves what Rahner wants to accomplish with the problematic category of existential ethics and simultaneously provides more coherent and explicit safeguards against situationalism and abuse.2 Rahner's chief expositor, James F. Bresnahan, claims in his extensive dissertation on Rahner's ethics that the extent of Wallace's misunderstanding of "the need for ' existential ' ethics is hard to convey in a short space," and that Wallace is wrong in thinking that Rahner displaces prudence.3 In the 1 William A. Wallace, O.P., "The Existential Ethics of Karl Rahner: A Thomistic Appraisal,'' in The Thomist, 1963, vol. 27, pp. 493-515. 2 Ibid., pp. 510-513. a James F.

NELSON course of this exchange, not much is said by either party about the characteristics of the virtue oi prudence itself. An investigation into the function and status assigned to prudence by St. Thomas may be of use for deciding whether existential ethics is in keeping with his moral teaching or, rather, a distortion. But first, in order to evaluate Wailace's criticism and claim that prudence is a preferable alternative to Rahner's proposal, a brief description of Rahner's categories of essential and exi,;tential ethics is in order.4 Rahner uses the category of essential ethics in two ways. First, he identifies it Yvith what he portrays as a somewhat static and conservative natural-law tradition. Second, he uses it to refer to his own description of a rehabilitated dimension of ethical reasoning that complements and calls for a supplemental category of existential ethics. Essential ethics in both cases refers to the moral principles or laws derived from knowledge of the essential elements of human nature. The difference has to do primarily with disagreement about what it is that constitutes human essence. According to Rahner, essence is much less unchangeable and much more " open " than traditionally or ordinarily assumed. As a consequence, he argues, claims about natural law should be less absolute and universal than they often are. Whether one understands essence as fixed or fluid, however, essential ethics involves a syllogistic application of natural law to circumstances. A universal principle based on human essence 4 An understanding of Rahner's ethics is macle difficult by several factors: his thinking is deeply indebted to " transcendental" Continental philosophy; some of the relevant texts and criticisms are available only in German; passages dealing with ethics appear in widely scattered (and unindexed) essays; he does not conceive of himself primarily as an ethicist and thus is not systematic in his discussion of his moral theory; his prose may be charitably described as challenging; and the only extensive analysis of his ethics written in English is Bresnahan's 650-page dissertation, which contains a wealth of information and explication. Bresnahan has published two helpful summaries: "Rahner's Christian Ethics: in America, 1970, vol. 123, pp. 351-354 ancl "Rahner's Ethics: Critical Natural Law in Relation to Contemporary Ethical Methodology," in the Journal of Religion, Jan. 1976, vol. 56, pp. 36-660.

This Festschrift in Professor Kristeller’s honor consists of contributions by scholars who have had some connection with Columbia University, his "intellectual home in the United States for three decades." It also includes a Tabula Gratulatoria listing many other friends from the United States and Europe. The editor’s opening essay provides an interesting and informative account of this scholar’s academic career, and should be read together with the complete annotated bibliography of his publications through 1974. The latter lists 149 "major publications" (...) and 220 "minor publications." Kristeller’s contributions to the history of Renaissance philosophy are well known to historians of philosophy, and deservedly so. Here reference should be made to his groundbreaking studies on Marsilio Ficino and Pomponazzi, and on others such as Pico della Mirandola and Petrarch, as well as on Renaissance Platonism, Aristotelianism in the Renaissance, Thomism in the Renaissance, Paduan Averroism, and Alexandrism. But he has also contributed greatly to the fields of medieval and Renaissance history, and especially to our understanding of Renaissance humanism, Renaissance music, and Renaissance art. He is universally recognized as one of the world’s foremost authorities on manuscript research, as is witnessed, for example, by the cooperative project, Catalogus Translationum et Commentariorum, which he founded, and by his Iter ltalicum. In all of these enterprises he has set an enviable example for other scholars by the exacting standards and the breadth of his expertise. It is only fitting, then, that the many essays in this Festschrift should reflect the breadth and depth of the scholarship so evident in the man to whom they are dedicated. Limitations of space will only permit us to list them here, with a few remarks reserved for those of more special interest to philosophers and historians of philosophy: Eugene F. Rice, Jr., "The De magia naturali of Jacques Lefèvre d’Etaples" ; Donald R. Kelley, "Louis Le Caron Philosophe", on Le Caron’s effort to bring together jurisprudence and classical, especially Platonic, philosophy; Richard H. Popkin, "The Pre-Adamite Theory in the Renaissance", with fascinating material about theories concerning men before Adam in La Peyrère and widely scattered earlier sources; Richard Lemay, "The Fly against the Elephant: Flandinus against Pomponazzi on Fate", on an unedited attack by an Augustinian Bishop against Pomponazzi’s espousal of the Stoic doctrine of fate; Martin Pine, "Pietro Pomponazzi and the Medieval Tradition of God’s Foreknowledge", on Pomponazzi’s solution to the problem of divine foreknowledge and human freedom inlight of his familiarity with earlier discussions by Boethius, Aquinas, Scotus, and Ockham; F.

The Pragmatism Reader is the essential anthology of this important philosophical movement. Each selection featured here is a key writing by a leading pragmatist thinker, and represents a distinctively pragmatist approach to a core philosophical problem. The collection includes work by pragmatism's founders, Charles Peirce, William James, and John Dewey, as well as seminal writings by mid-twentieth-century pragmatists such as Sidney Hook, C. I. Lewis, Nelson Goodman, Rudolf Carnap, Wilfrid Sellars, and W.V.O. Quine. This reader also includes the (...) most important work in contemporary pragmatism by philosophers like Susan Haack, Cornel West, Hilary Putnam, Richard Rorty, Cheryl Misak, and Robert Brandom. Each selection is a stand-alone piece--not an excerpt or book chapter--and each is presented fully unabridged. The Pragmatism Reader challenges the notion that pragmatism fell into a midcentury decline and was dormant until the advent of "neopragmatism" in the 1980s. This comprehensive anthology reveals a rich and highly influential tradition running unbroken through twentieth-century philosophy and continuing today. It shows how American pragmatist philosophers have contributed to leading philosophical debates about truth, meaning, knowledge, experience, belief, existence, justification, and freedom. Covers pragmatist philosophy from its origins to today Features key writings by the leading pragmatist thinkers Demonstrates the continuity and enduring influence of pragmatism Challenges prevailing notions about pragmatism Includes only stand-alone pieces, completely unabridged Reflects the full range of pragmatist themes, arguments, concerns, and commitments.

In the United States, physicians are Increasingly functioning In the consultative role. This change in role Is undoubtedly a result of a surge in the numbers of specialists, the relative decreasing number of primary care physicians, and the emergence of tertiary care centers as primary treatment providers. This change In the style of practicing medicine has led to role confusion In attending physician-patient-consultant relationships.

The goal of this chapter is to describe recollective memory and give an account of some of the characteristics of this form of human memory. I take recollective memory to be the type of memory that occurs when an individual recalls a specific episode from their past experience. I start with this very loose definition because a large part of this chapter consists of an attempt to work out a more detailed and analytic description of this form of memory.

A discussion of Christian ethics focuses on the physician's image as a parent, warrior against death, expert, and teacher, and the oath that guides his or her practice.

This article articulates and defends F. H. Bradley's regress argument against external relations using contemporary analytic techniques and conceptuality. Bradley's argument is usually quickly dismissed as if it were beneath serious consideration. But I shall maintain that Bradley's argument, suitably reconstructed, is a powerful argument, plausibly premised, and free of such obvious fallacies as petitio principii. Thus it does not rest on the question‐begging assumption that all relations are internal, as Russell, and more recently van Inwagen, maintain. Bradley does not (...) attack external relations in order to affirm a doctrine of internal relations, and his monism is not derived from the internality of all relations, but from the self‐contradictory nature of all relations. For Bradley, it is the “relational situation”as such that is ontologically defective. (shrink)

We use evidence from cognitive psychology and the history of science to examine the issue of the theory-ladenness of perceptual observation. This evidence shows that perception is theory-laden, but that it is only strongly theory-laden when the perceptual evidence is ambiguous or degraded, or when it requires a difficult perceptual judgment. We argue that debates about the theory-ladenness issue have focused too narrowly on the issue of perceptual experience, and that a full account of the scientific process requires an examination (...) of theory-ladenness in attention, perception, data interpretation, data production, memory, and scientific communication. We conclude that the evidence for theory-ladenness does not lead to a relativist account of scientific knowledge. (shrink)

The doctrine of divine simplicity, according to which God is devoid of physical or metaphysical complexity, is widely believed to be incoherent. I argue that although two prominent recent attempts to defend it fail, it can be defended against the charge of obvious incoherence. The defense rests on the isolation and rejection of a crucial assumption, namely, that no property is an individual. I argue that there is nothing in our ordinary concepts of property and individual to warrant the assumption, (...) and that once the assumption is rejected, the way is clear to viewing the divine attributes as self-exemplifying properties whose self-exemplification entails their identity with an individual.

This book is intended to help transform epistemology - the traditional study of knowledge - into a rigorous discipline by removing conceptual roadblocks and developing formal tools required for a fully naturalized epistemology. The evolutionary approach which Harms favours begins with the common observation that if our senses and reasoning were not reliable, then natural selection would have eliminated them long ago. The challenge for some time has been how to transform these informal musings about evolutionary epistemology into a rigorous (...) theoretical discipline capable of complementing current scientific studies of the evolution of cognition with a philosophically defensible account of meaning and justification.

Various laws and theories in the natural and social sciences are presented with a view to discerning the syntactic and semantic characteristics of many idealizations in science. Three different kinds of idealizations are discussed: ideal conditions, ideal cases, and idealized theories. An ideal condition is a formula in which state variables occur, whose existential closure is false, and for which there is another formula that can be constructed out of the original formula such that the existential closure of the new (...) formula is true. An ideal case is a statement which is logically equivalent to a universal conditional which has an ideal condition as its antecedent. And an idealized theory is a set of false universal conditional statements. Alternative syntactic and semantic analyses are viewed and criticized. (shrink)

Modern professionals wield considerable power by virtue of their knowledge. However, they also feel beleaguered by the constraints they face and the public disapproval they often experience. These pressures combine to diminish the professional's sense of public responsibility and convert him or her in self-perception to a careerist.

Conventional wisdom has it that evolution makes a sham of morality, even if morality is an adaptation. I disagree. I argue that our best current adaptationist theory of meaning offers objective truth conditionsfor signaling systems of all sorts. The objectivity is, however, relative to species – specifically to the adaptive history of the signaling system in question. While evolution may not provide the kind of species independent objective standards that (e.g.) Kantians desire, this should be enough for the practical work (...) of justifying our confidence in the objectivity of moral standards. If you believe morality is an adaptation, you should be a moral realist. (shrink)

In his Critique of Pure Reason, Kant makes the interesting, but obscure claim that the normative constraints that constitute the objectivity of our representations have their source ultimately in transcendental apperception. Keller focuses on this claim. He interprets Kant’s condition of transcendental apperception as the claim that I must represent myself in an impersonal way, and he argues that impersonal self-consciousness is a necessary condition under which I can distinguish my particular take on things from the way things are independently (...) of my own perspective on them. He elaborates his interpretation and defense of the condition of transcendental self-consciousness by discussing its role in each of the central arguments in the Critique in which the notion importantly figures: the transcendental deduction in both the first edition and in the second, the Analogies of Experience, the Paralogisms, and the second-edition refutation of idealism.

In this paper we provide a psychological account of the nature and development of explanation. We propose that an explanation is an account that provides a conceptual framework for a phenomenon that leads to a feeling of understanding in the reader/hearer. The explanatory conceptual framework goes beyond the original phenomenon, integrates diverse aspects of the world, and shows how the original phenomenon follows from the framework. We propose that explanations in everyday life are judged on the criteria of empirical accuracy, (...) scope, consistency, simplicity, and plausibility. We conclude that explanations in science are evaluated by the same criteria, plus those of precision, formalisms, and fruitfulness. We discuss several types of explanation that are used in everyday life – causal/mechanical, functional, and intentional. We present evidence to show that young children produce explanations that have the same essential form as those used by adults. We also provide evidence that children use the same evaluation criteria as adults, but may not apply those additional criteria for the evaluation of explanations that are used by scientists.

A brief discussion is offered of what it means to say that a set of statements provides D-N explanation with special emphasis given to approximative D-N explanation. An idealized theory is seen to provide approximative D-N explanation. An ideal case provides explanation only if postulates are offered which connect the ideal antecedent condition with actual conditions. Such postulates will help in accounting for deviations between what the consequent of the ideal case entails and what actually occurs. Three ways are presented (...) for deciding on the acceptability of idealizations: (i) as actual conditions more closely approximate the ideal antecedent conditions specified in an ideal case, the more closely actual cases ought to approximate the consequent of the ideal case; (ii) the additional postulates connecting ideal antecedent conditions with actual conditions ought to account for deviations between what is entailed by an idealized theory and what actually occurs; and (iii) an idealized theory is explained by a more general theory when certain state variables in the more general theory are given extreme values. It is argued that (iii) is not a necessary condition for the acceptability of idealizations. (shrink)

The realization that prokaryotes naturally and frequently disperse genes across steep taxonomic boundaries via lateral gene transfer gave wings to the idea that eukaryotes might do the same. Eukaryotes do acquire genes from mitochondria and plastids and they do transfer genes during the process of secondary endosymbiosis, the spread of plastids via eukaryotic algal endosymbionts. From those observations it, however, does not follow that eukaryotes transfer genes either in the same ways as prokaryotes do, or to a quantitatively similar degree. (...) An important illustration of the difference is that eukaryotes do not exhibit pangenomes, though prokaryotes do. Eukaryotes reveal no detectable cumulative effects of LGT, though prokaryotes do. A critical analysis suggests that something is deeply amiss with eukaryote LGT theories. In prokaryotes, genes from the environment can enter the genome via lateral gene transfer. In eukaryote genetics, natural variation comes from within the genome, not from the environment. Yet many reports claim that eukaryotes undergo LGT just like prokaryotes. Such claims do not withstand scrutiny and are probably untrue. (shrink)

Extracorporeal membrane oxygenation (ECMO) is a form of life support for cardiac and/or pulmonary failure with unique ethical challenges compared to other forms of life support. Ethical challenges with ECMO exist when conventional standards of care apply, and are exacerbated during periods of absolute ECMO scarcity when “crisis standards of care” are instituted. When conventional standards of care apply, we propose that it is ethically permissible to withhold placing patients on ECMO for reasons of technical futility or when patients have (...) terminal, short-term prognoses that are untreatable by ECMO. Under crisis standards of care, it is ethically permissible to broaden exclusionary criteria to also withhold ECMO from patients who have a low likelihood of recovery, to maximize the overall number of lives saved. Unilateral withdrawal of ECMO against a patient’s preferences is unethical under conventional standards of care, but is ethical under crisis standards of care to increase access to ECMO to others in society. ECMO should only be rationed when true scarcity exists, and allocation protocols should be transparent to the public. When rationing must occur under crisis standards of care, it is imperative that oversight bodies assess for inequities in the allocation of ECMO and make frequent changes to improve any inequities.

Does the cosmological argument (CA) depend on the ontological (OA)? That depends. If the OA is an argument “from mere concepts,” then no; if the OA is an argument from possibility, then yes. That is my main thesis. Along the way, I explore a number of subsidiary themes, among them, the nature of proof in metaphysics, and what Kant calls the “mystery of absolute necessity.”.

William F. May, a leading expert on medical ethics, here explores two of today's most crucial tests of the traditional covenant between physicians and patients--active euthanasia and health care reform.

The metamemory approach to memory confidence was extended and elaborated to deal with semantic memory tasks. The metamemory approach assumes that memory confidence is based on the products and processes of a completed memory task, as well as metamemory beliefs that individuals have about how their memory products and processes relate to memory accuracy. In two experiments participants were asked deceptive and nondeceptive questions involving geographical information. In both experiments, as predicted by the metamemory approach to memory confidence, there was (...) a positive confidence/ accuracy relationship for nondeceptive items and a negative relationship for deceptive items. Experiment 2 used items that constrained the memory strategies (e.g., hierarchical reasoning about spatial location) used by the participants. The results supported the hypothesis that the participants were aware of the levels of memory accuracy associated with the different strategies and used that information to generate their memory confidence judgments.

Information theory offers a measure of "mutual information" which provides an appropriate measure of tracking efficiency for the naturalistic epistemologist. The statistical entropy on which it is based is arguably the best way of characterizing the uncertainty associated with the behavior of a system, and it is ontologically neutral. Though not appropriate for the naturalization of meaning, mutual information can serve as a measure of epistemic success independent of semantic maps and payoff structures. While not containing payoffs as terms, mutual (...) information places both upper and lower bounds on payoffs. This constitutes a non-trivial relationship to utility. (shrink)

The concept of information tempts us as a theoretical primitive, partly because of the respectability lent to it by highly successful applications of Shannon’s information theory, partly because of its broad range of applicability in various domains, partly because of its neutrality with respect to what basic sorts of things there are. This versatility, however, is the very reason why information cannot be the theoretical primitive we might like it to be. “Information,” as it is variously used, is systematically ambiguous (...) between whether it involves continuous or discrete quantities, causal or noncausal relationships, and intrinsic or relational properties. Many uses can be firmly grounded in existing theory, however. Continuous quantities of information involving probabilities can be related to information theory proper. Information defined relative to systems of rules or conventions can be understood relative to the theory of meaning . A number of causal notions may possibly be located relative to standard notions in physics. Precise specification of these distinct properties involved in the common notion of information can allow us to map the relationships between them. Consequently, while information is not in itself the kind of single thing that can play a significant unifying role, analyzing its ambiguities may facilitate headway toward that goal. (shrink)
