This article draws on scientific explanations of obesity to motivate the creation of a system of paternalistic public health interventions into the obesity epidemic. Libertarian paternalists argue that paternalism is warranted in light of the cognitive limits of human decision-making abilities. There are further, specific biological limits on our capacity to choose and maintain a healthy diet. These biological facts strengthen the general motivation for libertarian paternalism. As a consequence, the creation of a system of paternalistic public health interventions into (...) the obesity epidemic is warranted. (shrink)

This paper considers recent heated debates led by Jerry A. Coyne andMichael J. Wade on issues stemming from the 1929–1962 R.A. Fisher-Sewall Wrightcontroversy in population genetics. William B. Provine once remarked that theFisher-Wright controversy is central, fundamental, and very influential.Indeed,it is also persistent. The argumentative structure of therecent (1997–2000) debates is analyzed with the aim of eliminating a logicalconflict in them, viz., that the two sides in the debates havedifferent aims and that, as such, they are talking past each other. (...) Given aphilosophical analysis of the argumentative structure of the debates,suggestions supportive of Wade's work on the debate are made that areaimed, modestly, at putting the persistent Fisher-Wright controversy on thecourse to resolution.

The dissertation is a critical examination of theory evaluation in population genetics. There are three main philosophical approaches to theory evaluation in philosophy of science: confirmation and hypothesis testing, scientific change, and experimentation. Accounts that champion each of the main philosophical approaches to scientific theory evaluation are represented in philosophy of biology: confirmation and hypothesis testing by Elisabeth A. Lloyd, scientific change by Lindley Darden, and experimentation by David W. Rudge. I argue that each of the main approaches is insufficient (...) for evaluating population genetics theories. However, the accounts I critique are not fundamentally incompatible. I modify, unify, and extend them into a comprehensive account of theory evaluation for population genetics. ;My philosophical analysis is driven by a complex, important, and ongoing controversy in population genetics, viz., the R. A. Fisher-Sewall Wright controversy in population genetics. I use my historical case study to assess the adequacy of both the extant philosophical analyses of theory evaluation and my own account. Between 1929 and 1962 Fisher and Wright debated the main differences emanating from their alternative approaches to evolutionary theorizing. The debates between Fisher and Wright functionally ended with Fisher's death. However, Wright continued to clarify his position in the controversy until his death in 1988, and other biologists have continued work on the core debates. ;Recently, four scientific papers led by biologists Jerry A. Coyne and Michael J. Wade have been key in revisiting and rekindling the Fisher-Wright controversy with analyses of old theoretical and empirical issues as well as new developments that have spun off the older work. Four decades after the debates between Fisher and Wright, these papers have staked out, with substantial disagreement, claims about the evaluative status of the two predominant population genetics approaches to evolution in the field. A further task of this dissertation is to provide a non-partisan evaluation of the last 40 years of work on the controversy, i.e., the controversy since Fisher's death in 1962. It is hoped that such a critical analysis of the controversy will advance it to some extent. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

: Where there are cases of underdetermination in scientific controversies, such as the case of the molecular clock, scientists may direct the course and terms of dispute by playing off the multidimensional framework of theory evaluation. This is because assessment strategies themselves are underdetermined. Within the framework of assessment, there are a variety of trade-offs between different strategies as well as shifting emphases as specific strategies are given more or less weight in assessment situations. When a strategy is underdetermined, scientists (...) can change the dynamics of a controversy by making assessments using different combinations of evaluation strategies and/or weighting whatever strategies are in play in different ways. Following an underdetermination strategy does not end or resolve a scientific dispute. Consequently, manipulating underdetermination is a feature of controversy dynamics and not controversy closure.

We critique a series of recent papers in which Reidenbach and Robin developed a multidimensional ethics scale. Our critique raises four problems for the scale. First, it is not clear what the scale measures. Second, the semantic differential items used in the scale seem problematic. Third, the scale omits several important ethical rationales. Finally, no caveats accompany the scale to alert managers about its proper and improper use.

In the 11th chapter of the second book of Samuel, we read how King David saw Bathsheba in the evening: ‘v.2. And it came to pass in an eveningtide, that David arose from off his bed, and walked upon the roof of the king's house: and from the roof he saw a woman washing herself; and the woman was very beautiful to look upon.’.

Criminal attempts, it is often said, are crimes of intention. While many complete crimes can be committed recklessly, criminal attempts require “purposive conduct”; in attempts “the intent is the essence of the crime.” But what kind of intention is required; what must be intended, or purposed, by someone who is to be guilty of a criminal attempt?

After distinguishing different species of Legal Moralism I outline and defend a modest, positive Legal Moralism, according to which we have good reason to criminalize some type of conduct if it constitutes a public wrong. Some of the central elements of the argument will be: the need to remember that the criminal law is a political, not a moral practice, and therefore that in asking what kinds of conduct we have good reason to criminalize, we must begin not with the (...) entire realm of wrongdoing, but with conduct falling within the public realm of our civic life; the need to look at the different processes of criminalization, and to ask what kinds of consideration can properly figure in those processes; the need to attend to the relationship, and the essential differences, between criminal law and other modes of legal regulation.

We construct a nonlow2 r.e. degree d such that every positive extension of embeddings property that holds below every low2 degree holds below d. Indeed, we can also guarantee the converse so that there is a low r.e. degree c such that that the extension of embeddings properties true below c are exactly the ones true belowd.Moreover, we can also guarantee that no b ≤ d is the base of a nonsplitting pair.

Part of the Studies in Crime and Public Policy series, this book, written by one of the top philosophers of punishment, examines the main trends in penal theorizing over the past three decades. Duff asks what can justify criminal punishment, and then explores the legitimacy of actual practices by examining what would count as adequate justification for them. Duff argues that a "communicative conception of punishment," which he presents as a third way between consequentialist and retributive theories, offers the most (...) fruitful way of understanding punishment's meaning and justification. Duff addresses such questions as how much sentences should be constrained by proportionality requirements; what modalities of punishment best communicate their intended meaning; and what decisionmaking procedures he envisions. This book will appeal to criminologists, philosophers, and others interested in theories of punishment. (shrink)

After an initial discussion (§i) of what a theory of criminal law might amount to, I sketch (§ii) the proper aims of a liberal, republican criminal law, and discuss (§§iii–iv) two central features of such a criminal law: that it deals with public wrongs, and provides for those who perpetrate such wrongs to be called to public account. §v explains why a liberal republic should maintain such a system of criminal law, and §vi tackles the issue of criminalization—of how we (...) should determine the proper scope of the criminal law.

This essay examines the origin of genotype-environment interaction, or G×E. "Origin" and not "the origin" because the thesis is that there were actually two distinct concepts of G×E at this beginning: a biometric concept, or \[G \times E_B\], and a developmental concept, or \[G \times E_D \]. R. A. Fisher, one of the founders of population genetics and the creator of the statistical analysis of variance, introduced the biometric concept as he attempted to resolve one of the main problems in (...) the biometric tradition of biology - partitioning the relative contributions of nature and nurture responsible for variation in a population. Lancelot Hogben, an experimental embryologist and also a statistician, introduced the developmental concept as he attempted to resolve one of the main problems in the developmental tradition of biology - determining the role that developmental relationships between genotype and environment played in the generation of variation. To argue for this thesis, I outline Fisher and Hogben's separate routes to their respective concepts of G × E; then these separate interpretations of G × E are drawn on to explicate a debate between Fisher and Hogben over the importance of G × E, the first installment of a persistent controversy. Finally, Fisher's \[G \times E_B\] and Hogben's \[G \times E_D \] are traced beyond their own work into mid-2Oth century population and developmental genetics, and then into the infamous IQ Controversy of the 1970s.

We present an account of processing capacity in the ACT-R theory. At the symbolic level, the number of chunks in the current goal provides a measure of relational complexity. At the subsymbolic level, limits on spreading activation, measured by the attentional parameter W, provide a theory of processing capacity, which has been applied to performance, learning, and individual differences data.

Marcia Baron has offered an illuminating and fruitful discussion of extra-legal excuses. What is particularly useful, and particularly important, is her focus on our excusatory practices—on the ways and contexts in which we make, offer, accept, bestow and reject excuses: if we are to reach an adequate understanding of excuses, their implications and their grounds, we must attend to the roles that they can play in our human activities and relationships—and to the complexities and particularities of those roles. However, I (...) want to focus my comments less on the details of Baron’s discussions of excuses in extra-legal contexts than on the implications of her discussion for our understanding of excuses in the criminal law. What light (if any, a sceptic might add) can such analyses of our extra-legal concepts and practices throw on legal concepts and doctrines? (shrink)

Three arguments are proposed against the idea that ordinary talk about the mind constitutes a folk psychology, a sort of prescientific theory which explains human behaviour and which is ripe for replacement by a neurological or computational theory with better scientific credentials. First, not all talk of the mind is introduced to explain in the way assumed by those who think that mental talk hypothesizes inner processes to explain behaviour. Second, the individuation of the behaviour which is explained by the (...) inner processes itself requires reference to ?mental? states such as intentions or desires. Consequently the project is circular. Finally, scientific theory is a practice with a history which may be matched in the case of ordinary talk of the mind. Certainly ordinary talk of motives, intentions, and thoughts may be infected by the theorizing of economists and sociologists et al., but it is impossible that all talk of the mind should be theoretical in this way.

I begin by discussing the ways in which a would-be blamer's own prior conduct towards the person he seeks to blame can undermine his standing to blame her. This provides the basis for an examination of a particular kind of 'bar to trial' in the criminal law – of ways in which a state or a polity's right to put a defendant on trial can be undermined by the prior misconduct of the state or its officials. The examination of this (...) often neglected legal phenomenon illuminates some central features of the criminal law and the criminal process, and some of the preconditions for the legitimacy of the criminal law in a liberal republic.

How can a system of criminal punishment be justified? In particular can it be justified if the moral demand that we respect each other as autonomous moral agents is taken seriously? Traditional attempts to justify punishment as a deterrent or as retribution fail, but Duff suggests that punishment can be understood as a communicative attempt to bring a wrong-doer to repent her crime. This account is supported by discussions of moral blame, of penance, of the nature of the law's demands, (...) and of the proper meaning and purpose of the criminal process of trial and verdict: it deals both with the ideals that should inform a system of criminal law and the extent to which those ideals are actualised in existing institutions and practices. The conclusion is pessimistic: punishment cannot be justified within our legal system; and this gap between the ideal and the actual presents us with serious moral dilemmas. (shrink)

This is an able book of essays, written by well-qualified scholars, about an unjustly neglected nineteenth century German philosopher. He is known in this country primarily as the founder of "formal sociology," but much of what he has to say belongs with equal propriety to the philosophy of culture. The aim of the volume is to rehabilitate Simmel's reputation, which suffered much among sociologists from attacks by Abel and Sorokin. The volume also contains about 100 pages of Simmel's own essays (...) in translation: "The Ruin," "The Handle," and "The Aesthetic Significance of the Face," among others.--A. R. A. (shrink)

The human person makes great demands on the physician and calls for unique attention. Hence the doctor-patient relationship calls for the highest ideals of kindness, patience, trustworthiness, generosity and skill. The Catholic physician brings to these demands a specific meaning: ministering to the sick is to see Christ in them and to show Him to them.

The literature fails to reflect general agreement over the nature of the services and procedures provided by bioethicists, and the training and core competencies this work requires. If bioethicists are to define their activities in a consistent way, it makes sense to look for common ground in shared communities of practice. We report results of a survey of the services and procedures among bioethicists affiliated with the University of Toronto Joint Centre for Bioethics (JCB). This is the largest group of (...) bioethicists working in healthcare organizations in Canada. The results suggest there are many common services and procedures of JCB bioethicists. This survey can serve as a baseline for further exploration of the work of JCB bioethicists. Common practices exist with respect to the domains of practice, individual reporting relationships, service availability within business hours and the education and training of the bioethicist.
