Philosophy long sought to set knowledge on a firm foundation, through derivation of indubitable truths by infallible rules. For want of such truths and rules, the enterprise foundered. Nevertheless, foundationalism's heirs continue their forbears' quest, seeking security against epistemic misfortune, while their detractors typically espouse unbridled coherentism or facile relativism. Maintaining that neither stance is tenable, Catherine Elgin devises a via media between the absolute and the arbitrary, reconceiving the nature, goals, and methods of epistemology. In Considered Judgment, she argues (...) for a reconception that takes reflective equilibrium as the standard of rational acceptability. A system of thought is in reflective equilibrium when its components are reasonable in light of one another, and the account they comprise is reasonable in light of our antecedent convictions about the subject it concerns.Many epistemologists now concede that certainty is a chimerical goal. But they continue to accept the traditional conception of epistemology's problematic. Elgin suggests that in abandoning the quest for certainty we gain opportunities for a broader epistemological purview--one that comprehends the arts and does justice to the sciences. She contends that metaphor, fiction, emotion, and exemplification often advance understanding in science as well as in art. The range of epistemology is broader and more variegated than is usually recognized. Tenable systems of thought are neither absolute nor arbitrary. Although they afford no guarantees, they are good in the way of belief. (shrink)

The current paper synthesizes theory and data from the field of life history (LH) evolution to advance a new developmental theory of variation in human LH strategies. The theory posits that clusters of correlated LH traits (e.g., timing of puberty, age at sexual debut and first birth, parental investment strategies) lie on a slow-to-fast continuum; that harshness (externally caused levels of morbidity-mortality) and unpredictability (spatial-temporal variation in harshness) are the most fundamental environmental influences on the evolution and development of LH (...) strategies; and that these influences depend on population densities and related levels of intraspecific competition and resource scarcity, on age schedules of mortality, on the sensitivity of morbidity-mortality to the organism’s resource-allocation decisions, and on the extent to which environmental fluctuations affect individuals versus populations over short versus long timescales. These interrelated factors operate at evolutionary and developmental levels and should be distinguished because they exert distinctive effects on LH traits and are hierarchically operative in terms of primacy of influence. Although converging lines of evidence support core assumptions of the theory, many questions remain unanswered. This review demonstrates the value of applying a multilevel evolutionary-developmental approach to the analysis of a central feature of human phenotypic variation: LH strategy. (shrink)

“Clinical ethics consultants” have been practicing in the United States for about 50 years. Most of the earliest consultants—the “pioneers”—were “outsiders” when they first appeared at patients' bedsides and in the clinic. However, if they were outsiders initially, they acclimated to the clinical setting and became “insiders” very quickly. Moreover, there was some tension between traditional academics and those doing applied ethics about whether there was sufficient “critical distance” for appropriate reflection about the complex medical ethics dilemmas of the day (...) if one were involved in the decision making. Again, the pioneers deflected concerns by identifying and instituting safeguards to assure professional objectivity in clinical ethics consultation services. One might suggest that in moving inside and establishing normative practices, the pioneer clinical ethics consultants anticipated adoption of their routines and professionalization of the field.

James Sterba has constructed a powerful argument for there being a conflict between the presence of evil in the world and the existence of God. I contend that Sterba’s argument depends on a crucial assumption, namely, that God has an obligation to act according to the principle of meticulous providence. I suggest that two of his analogies confirm his dependence on this requirement. Of course, his argument does not rest on either of these analogies, but they are illustrative of the (...) role that meticulous providence plays in his argument. I then investigate the ethical principles Sterba invokes in his use of meticulous providence and suggest that not only do we often not predicate goodness of human persons based on these principles of obligation, but that these principles are much too stringent to function to determine moral obligations and moral goodness. From there, I contend that to think that God has a similar obligation regarding meticulous providence in order to be good encounters several serious problems, especially with respect to the soul-building Sterba wants to preserve. I conclude by considering Sterba’s reply in terms of a limited application of meticulous providence. (shrink)

The study of the relationship between religion and health has grown substantially in the past decade. There is little doubt that religion plays an important role in many people's lives and that this has an impact on their health. The question is how researchers and clinicians can best evaluate the available information and how we can improve upon the current findings. In this essay we review the current knowledge regarding religion and health and also critically review issues pertaining to methodology, (...) findings, and interpretation of these studies. It is important to maintain a rigorous perspective with regard to such studies and also to recognize inherent limitations and suggest constructive ways in which to advance this field of study. In the end, such an approach can provide new information that will improve our understanding of the overall relationship between religion and health. (shrink)

Biomedical ethics is an essential part of the medical curriculum because it is thought to enrich moral reflection and conduce to ethical decisionmaking and ethical behavior. In recent years, however, the received idea that competency in moral reasoning leads to moral responsibility “in the field” has been the subject of sustained attention. Today, moral education and development research widely recognize moral reasoning as being but one among at least four distinguishable dimensions of psychological moral functioning alongside moral motivation, moral character, (...) and moral sensitivity. In a reflection of this framework, medical educators and curriculum planners repeatedly advance the idea that educators should be concerned with supporting empathy, and this, very often, as a means of improving on and broadening medical ethics education’s traditional focus on moral reasoning.

As clinical ethics consultants move toward professionalization, the process of certifying individual consultants or accrediting programs will be discussed and debated. With certification, some entity must be established or ordained to oversee the standards and procedures. If the process evolves like other professions, it seems plausible that it will eventually include a written examination to evaluate the core knowledge competencies that individual practitioners should possess to meet peer practice standards. The American Society for Bioethics and Humanities has published core knowledge (...) competencies for many years that are accepted by experts as the prevailing standard. Probably any written examination will be based upon the ASBH core knowledge competencies. However, much remains to be done before any examination may be offered. In particular, it seems likely that a recognized examining board must create and validate examination questions and structure the examination so as to establish meaningful, defensible parameters after dealing with such challenging questions as: Should the certifying examination be multiple choice or short-answer essay? How should the test be graded? What should the pass rate be? How may the examination be best administered? To advance the field of health care ethics consultation, thought leaders should start to focus on the written examination possibilities, to date unaddressed carefully in the literature. Examination models—both objective and written—must be explored as a viable strategy about how the field of health care ethics consultations can grow toward professionalization. (shrink)

Newton certainly regarded his second law of motion in the Principia as a fundamental axiom of mechanics. Yet the works that came after the Principia, the major treatises on the foundations of mechanics in the eighteenth century—by Varignon, Hermann, Euler, Maclaurin, d’Alembert, Euler (again), Lagrange, and Laplace—do not record, cite, discuss, or even mention the Principia’s statement of the second law. Nevertheless, the present study shows that all of these scientists do in fact assume the principle that the Principia’s second (...) law asserts as a fundamental axiom in their mechanics. (For what that second law asserts, we rely on Newton’s own testimony.) Some, like Varignon and Hermann, assume the axiom implicitly, apparently unaware that any assumption is being made, while others, like Maclaurin and Euler, assume the axiom explicitly, apparently unaware that the assertion assumed is the second law as Newton himself understood it. But in every case these scientists employ the principle asserted by the Principia’s second law fundamentally, unaware that they should be citing Neutonus, Prin., Phil. Nat. Math., Lex II. (shrink)

The alleged conflict between religion and science most pointedly focuses on what it is to be human. Western philosophical thought regarding this has progressed through three broad stages: mind/body dualism, Neo-Darwinism, and most recently strong artificial intelligence (AI). I trace these views with respect to their relation to Christian views of humans, suggesting that while the first two might be compatible with Christian thought, strong AI presents serious challenges to a Christian understanding of personhood, including our freedom to choose, moral (...) choice itself, self-consciousness, and the relevance of God to our beginning, being, and ending.

I argue that a phenotypic trait can be an adaptation to a particular environmental condition, as against others, only if the environmental condition and the phenotype interactively cause fitness. Models of interactive environmental causes of fitness generally require that environments be individuated by explicit representation rather than by measures of environmental quality, although the latter understanding of ‘environment’ is more prominent in the philosophy of biology. Hence, talk of adaptations to some but not other environmental conditions relies on conceptions of (...) ‘environment’ importantly different from that commonly presupposed in philosophy of biology.

The first proposition of the Principia records two fundamental properties of an orbital motion: the Fixed Plane Property (that the orbit lies in a fixed plane) and the Area Property (that the radius sweeps out equal areas in equal times). Taking at the start the traditional view, that by an orbital motion Newton means a centripetal motion – this is a motion ``continually deflected from the tangent toward a fixed center'' – we describe two serious flaws in the Principia's argument (...) for Proposition 1, an argument based on a polygonal impulse approximation. First, the persuasiveness of the argument depends crucially on the validity of the Impulse Assumption: that every centripetal motion can be represented as a limit of polygonal impulse motions. Yet Newton tacitly takes the Impulse Assumption for granted. The resulting gap in the argument for Proposition 1 is serious, for only a nontrivial analysis, involving the careful estimation of accumulating local errors, verifies the Impulse Assumption. Second, Newton's polygonal approximation scheme has an inherent and ultimately fatal disability: it does not establish nor can it be adapted to establish the Fixed Plane Property. Taking then a different view of what Newton means by an orbital motion – namely that an orbital motion is by definition a limit of polygonal impulse motions – we show in this case that polygonal approximation can be used to establish both the fixed plane and area properties without too much trouble, but that Newton's own argument still has flaws. Moreover, a crucial question, haunted by error accumulation and planarity problems, now arises: How plentiful are these differently defined orbital motions? Returning to the traditional view, that Newton's orbital motions are by definition centripetal motions, we go on to give three proofs of the Area Property which Newton ``could have given'' – two using polygonal approximation and a third using curvature – as well as a proof of the Fixed Plane Property which he ``almost could have given.''.

Restorative Free Will examines free will as an adaptive capacity that evolved in humans and many other species, and restores free will to species excluded by claims of human uniqueness. Restorative Free Will recognizes the basic biological value of both libertarian and compatibilist elements of free will, and explains how these traditionally opposed accounts of free will capture an essential element of foraging animals' free will.

Did archaic Greek poets think that speech should be factually informative? Studies in the "history of thought" suggest that archaic culture offered no developed alternative to the opposition of truth to falsehood judged in relationship to fact. But the mythic poems display more interest in person-to-person agreement than eye-to-object fidelity. This is seen in the numerous stories where partnerships are negotiated and symbolized through tokens whose impersonal value is flagrantly disregarded. In the Hymn to Hermes, facetious non-truths establish intimacy and (...) cooperation among those who understand them. (shrink)

We ask God to involve himself providentially in our lives, yet we cherish our freedom to choose and act. Employing both theological reflection and philosophical analysis, the author explores how to resolve the interesting and provocative puzzles arising from these seemingly conflicting desires. He inquires what sovereignty means and how sovereigns balance their power and prerogatives with the free responses of their subjects. Since we are physically embodied in a physical world, we also need to ask how this is compatible (...) with our being free agents. Providence raises questions about God's fundamental attributes. The author considers what it means to affirm God's goodness as logically contingent, how being almighty interfaces with God's self-limitation, and the persistent problems that arise from claiming that God foreknows the future. Discussion of these divine properties spills over into the related issues of why God allows, or even causes, pain and suffering; why, if God is all-knowing, we need to petition God repeatedly and encounter so many unanswered prayers; and how miracles, as ways God acts in the world, are possible and knowable. Throughout, the author looks at Scripture and attends to how providence deepens our understanding of God and enriches our lives. (shrink)

Decisions about cardiopulmonary resuscitation may be based on medical prognosis, quality of life and patients' choices. Low survival rates indicate its overuse. Although the concept of medical futility has limitations, several strong predictors of non-survival have been identified and prognostic indices developed. Early results indicate that consideration of resuscitation in the elderly should be very selective, and support "opt-in" policies. In this minority of patients, quality of life is the principal issue. This is subjective and best assessed by the individual (...) in question. Patients' attitudes cannot be predicted reliably and surrogate decision-making is inadequate. Lay knowledge is poor. However, patients can use prognostic information to make rational choices. The majority welcome discussion of resuscitation and prefer this to be initiated by their doctors; many wish to decide for themselves. There is little evidence that this causes distress. The views of such patients, if competent, should be sought actively. (shrink)

The idea and use of the concept of intrinsic value in environmental ethics has spawned much debate in environmental ethics/axiology. Although for many, it seems fundamental and necessary for formulating an ethic for environmental protection, it seems to confuse and even undermine such efforts. ' Intrinsic value ' is, I argue, a concept born in the Western intellectual tradition for purposes of insulating and isolating those to whom intrinsic value can be attributed from one another and their environmental context. This (...) is especially true from the Modern period onward. When used as a basis for determining moral considerability, these Modern foundations engender contradictory and self-defeating ways of thinking about the individual/ecosystem relationship. As a result, formulations of moral sensibilities and principles become self-defeating and, vis-à-vis the ecological context, incoherent. On the critique of this Modern residue, an alternative axiological framework is built, using Anthony Weston's idea of interdepending values as a preparation for a more ecologically coherent approach to environmental protection. This approach is dialectical and attempts to formulate an ecological foundation for moral considerability. (shrink)

In this article I explore some statistical difficulties confronting going conceptions of ‘group’ as understood in accounts of group selection. Most such theories require real groups but define the reality of groups in ways that make it impossible to test for their reality. There are alternatives, but they either require or invite a nominalism about groups that many theorists abjure.

Health care spending comprises about 16% of the total United States gross domestic product and continues to rise. This article examines patterns of health care spending and the factors underlying their proportional growth. We examine the “usual suspects” most frequently cited as drivers of health care costs and explain why these may not be as important as they seem. We suggest that the drive for technological advancement, coupled with the entrepreneurial nature of the health care industry, has produced inherently inequitable (...) and unsustainable health care expenditure and growth patterns. Successful health reform will need to address these factors and their consequences. (shrink)

. The author argues, by analyzing the logic implicit in scientific and religious statements, that these two kinds of statements belong to different universes of discourse. Religious statements are not admissible into scientific discourse and scientific statements are not admissible into religious discourse. This separation of discourse into universes of discourse is based on validity conventions which legislate different kinds of truth criteria for statements in different universes.

Innovation is fundamental to cumulative culture, allowing progressive modification of existing technology. The authors define innovation as an asocial process, uninfluenced by social information. We argue that innovation is inherently social – innovation is frequently the product of modifying others' outputs, and successful innovations are acquired by others. Research should target examination of the cognitive underpinnings of socially-mediated innovations.

It is a truism that where one starts from and the direction one goes determines where one ends up. This is no less true in philosophy than elsewhere, and certainly no less true in matters dealing with the relationship between God’s foreknowledge and human free actions.

New forms of information technology, such as email, webpages and groupware, are being rapidly adopted. Intended to improve efficiency and effectiveness, these technologies also have the potential to radically alter the way people communicate in organizations. The effects can be positive or negative. This paper explores how technology can encourage or discourage moral dialogue -- communication that is open, honest, and respectful of participants. It develops a framework that integrates formal properties of ideal moral discourse, based on Habermas' theory of (...) communicative action, with properties of informal communication that help sustain good moral conversations. Ten criteria distilled from these works form the basis of a template that can be used for assessing the positive and negative impacts of emerging information technologies on moral dialogue. (shrink)

Abstract.As an undergraduate at Cambridge, Newton entered into his ‘Waste Book’ an assumption that we have named the Equivalence Assumption (The Younger): ‘‘ If a body move progressively in some crooked line [about a center of motion]..., [then this] crooked line may bee conceived to consist of an infinite number of streight lines. Or else in any point of the croked line the motion may bee conceived to be on in the tangent.’’ In this assumption, Newton somewhat imprecisely describes two (...) mathematical models, a ‘‘polygonal limit model’’ and a ‘‘tangent deflected model,’’ for ‘‘one-body motion,’’ that is, for the motion of a ‘‘body in orbit about a fixed center,’’ and then claims that these two models are equivalent. In the first part of this paper, we study the Principia to determine how the elder Newton would more carefully describe the polygonal limit and tangent deflected models. From these more careful descriptions, we then create Equivalence Assumption (The Elder), a precise interpretation of Equivalence Assumption (The Younger) as it might have been restated by Newton, after say 1687. We then review certain portions of the Waste Book and the Principia to make the case that, although Newton never restates nor even alludes to the Equivalence Assumption after his youthful Waste Book entry, still the polygonal limit and tangent deflected models, as well as an unspoken belief in their equivalence, infuse Newton’s work on orbital motion. In particular, we show that the persuasiveness of the argument for the Area Property in Proposition 1 of the Principia depends crucially on the validity of Equivalence Assumption (The Elder). After this case is made, we present the mathematical analysis required to establish the validity of the Equivalence Assumption (The Elder). Finally, to illustrate the fundamental nature of the resulting theorem, the Equivalence Theorem as we call it, we present three significant applications: we use the Equivalence Theorem first to clarify and resolve questions related to Leibniz’s ‘‘polygonal model’’ of one-body motion; then to repair Newton’s argument for the Area Property in Proposition 1; and finally to clarify and resolve questions related to the transition from impulsive to continuous forces in ‘‘De motu’’ and the Principia.

The book's key questions concern whether we have a right to believe whatever we choose and whether we have significant control over our beliefs. After exploring four case studies in which the question of a right to believe arises and querying what epistemic obligations are, we consider how epistemic obligations might be grounded, whether in prudence, morality, or human virtues. Some argue that epistemic excellence is less concerned with our obligations to believe the truth and avoid falsehood than with seeing (...) that the beliefs we hold are justified. We argue that our epistemic responsibility is best fulfilled somewhere in between the strict objectivist and strict subjectivist views. We proceed to defend the thesis that we have not only indirect but direct control over our beliefs. We then examine the nature of belief, contending for belief as both disposition and an action. In the final chapter we discuss the relation between epistemic obligations and moral accountability. (shrink)

Attempts to resolve the problem of evil often appeal to a greater good, according to which God’s permission of moral and natural evil is justified because (and just in case) the evil that is permitted is necessary for the realization of some greater good. In the extensive litany of greater good theodicies and defenses, the appeal to the greater good of an afterlife of infinite reward or pleasure has played a minor role in Christian thought but a more important role (...) in Islamic thought. In a recent article, Seyyed Jaaber Mousavirad invites us to reconsider a greater good theodicy of compensation. He contends that not only are all evils justified in that God compensates the sufferer in an afterlife, but because evils experienced produce some good, God has reason for bringing about or allowing evils in the first place (Mousavirad 211). In what follows I argue that this modified compensation theodicy is flawed in its premises, faces serious problems about its concept of justice, treats people as means only and not as intrinsically valuable, and ultimately fails to show that an afterlife compensation, along with some good produced here and now by evil, justify God bringing about or allowing evil.

Physicists and historians of science have always held that Isaac Newton should receive credit for the first proof that inverse-square orbits must be conics. This conviction derives from a brief argument, regarded as essentially correct, given by Newton in the Principia. Recently, however, it has been contended that this outline or sketch contains irreparable logical flaws. Here, the logical structure of this outline of Newton's, as well as the details that this outline omits, are carefully examined. We find that whilst (...) his argument does indeed contain a flaw, it is a minor omission rather than a serious logical error. Having rectified this omission, we show how Newton's outline expands into a convincing proof that inverse-square orbits must be conics. (shrink)

The design argument was rebutted by David Hume. He argued that the world and its contents (such as organisms) were not analogous to human artifacts. Hume further suggested that there were equally plausible alternatives to design to explain the organized complexity of the cosmos, such as random processes in multiple universes, or that matter could have inherent properties to self-organize, absent any external crafting. William Paley, writing after Hume, argued that the functional complexity of living beings, however, defied naturalistic explanations. (...) In effect he dared anyone to come up with an alternative to his inference to design, and hence a designer, outside of nature. Charles Darwin explained the apparent design of functional complexity by his theory of natural selection. Asa Gray, however, in essays as well as in correspondence with Darwin argued that natural selection allowed for a type of ‘evolutionary teleology’ in which design at most could be considered the result of universal principles. F.E. Hicks updated Hume by specifically objecting to the use of design arguments by Paley. Hicks argued that the apparent design seen in nature reflected order at a deep level in nature. The design argument was briefly revived by Lawrence Henderson early in the twentieth century but he ultimately concluded that design and teleology were not necessarily mutually entailing and he retracted his design argument in favor of one that he termed ‘natural teleology’. The current claims of ‘intelligent design’ have the same logical problems that have beset previous design arguments. If design is divorced from teleology and its discontents put behind us, then there is a possibility that the latter can have a place in the development of theories to explain the phenomena of emergent complexity.

argues that correlated interactions are necessary for group selection. His argument turns on a particular procedure for measuring the strength of selection, and employs a restricted conception of correlated interaction. It is here shown that the procedure in question is unreliable, and that while related procedures are reliable in special contexts, they do not require correlated interactions for group selection to occur. It is also shown that none of these procedures, all of which employ partial regression methods, are reliable when (...) correlated interactions of a specific kind arise, and it is argued that such correlated interactions will likely be ubiquitous in natural populations.
