Background: Expanded newborn screening generates incidental results, notably carrier results. Yet newborn screening programmes typically restrict parental choice regarding receipt of this non-health serving genetic information. Healthcare providers play a key role in educating families or caring for screened infants and have strong beliefs about the management of incidental results. Methods: To inform policy on disclosure of infant sickle cell disorder (SCD) carrier results, a mixed-methods study of healthcare providers was conducted in Ontario, Canada, to understand attitudes regarding result management (...) using a cross-sectional survey (N = 1615) and semistructured interviews (N = 42). Results: Agreement to reasons favouring disclosure of SCD carrier results was high (65.1%–92.7%) and to reasons opposing disclosure was low (4.1%–18.1%). Genetics professionals expressed less support for arguments favouring disclosure (35.3%–78.8%), and more agreement with arguments opposing disclosure (15.7%–51.9%). A slim majority of genetics professionals (51.9%) agreed that a reason to avoid disclosure was the importance of allowing the child to decide to receive results. Qualitatively, there was a perceived “duty” to disclose, that if the clinician possessed the information, the clinician could not withhold it. Discussion: While a majority of respondents perceived a duty to disclose the incidental results of newborn screening, the policy implications of these attitudes are not obvious. In particular, policy must balance descriptive ethics (ie, what providers believe) and normative ethics (ie, what duty-based principles oblige), address dissenting opinion and consider the relevance of moral principles grounded in clinical obligations for public health initiatives.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations in the paper.

Plato’s references to Empedocles in the myth of the Statesman perform a crucial role in the overarching political argument of the dialogue. Empedocles conceives of the cosmos as structured like a democracy, where the constituent powers ‘rule in turn’, sharing the offices of rulership equally via a cyclical exchange of power. In a complex act of philosophical appropriation, Plato takes up Empedocles’ cosmic cycles of rule in order to ‘correct’ them: instead of a democracy in which rule is shared cyclically (...) amongst equal constituents, Plato’s cosmos undergoes cycles of the presence and absence of a single cosmic monarch who possesses ‘kingly epistēmē’. By means of a revision of Empedocles’ democratic cosmology, Plato’s richly woven myth is designed precisely to reject the appropriateness of democracy as a form of human political association and legitimate monarchy in its stead.

A technological revolution with first order implications is undeniable and underway. That is the permeation of society by computers and telecommunications technology. For western society, committed to a social, economic, and value structure premised upon an industrial society, the move to an information society is more than disruptive; it is transformational. Current changes are so rapidly paced in relation to business planning that it creates major challenges and opportunities to reach out, influence, and guide the change.The telematics revolution will affect (...) every aspect of our society since it will affect every aspect of our world which involves the generation, production, storage, or handling of information. Many ethical issues are touched upon. To sum them up, the new immorality is to choose to act in ignorance of future consequences. (shrink)

The Principle of Sufficient Reason (PSR) holds that, for everything that exists or occurs or holds true, there is a reason why that is the case. I consider three possible ways of relating physics to the PSR: past states as reasons for present states, reasons why the laws of physics take the form that they do, and reasons why there is anything at all. In each case I suggest that the PSR is not the best way of thinking about how (...) and why physics works. -/- Invited reflection for The Principle of Sufficient Reason (Oxford Philosophical Concepts), Eds.

In lieu of an abstract, here is a brief excerpt of the content:Art, Mind, and IntentionNoël CarrollArt and Intention: A Philosophical Study, by Paisley Livingston ; 266 pp. oxford: oxford University Press, 2005, $74.00, $35.00 paper.The relevance of intention to the philosophy of art was perhaps first made explicit by G.W.F. Hegel who, in his monumental The Philosophy of Fine Art, narrowed the domain of aesthetics to art on the grounds that the beauty that pertains to art is the product (...) of mind. Though Hegel does not single out intention as the aspect of mind that impresses him, his definition of fine art in terms of that which possesses an aim that imbues the pertinent art with content makes it probable that what he is talking about is intention. Since Hegel's day, but maybe most especially in the last three decades, philosophers of art have relied upon the notion of intention to attempt to solve many of the recurring problems of their field, including not only issues involving art status, but those involving authorship, interpretation, and fictional truth, among others. In Art and Intention: A Philosophical Study, Paisley Livingston has performed the very valuable service of corralling a substantial number of topics regarding the intersection of art and intention between the covers of one book.Although there are books devoted to exploring the relation of art and intention with respect to specific topics, most notably interpretation, there is, to my knowledge, no other book like Livingston's that surveys such a diversity of issues concerning the nexus of intention and the [End Page 394] philosophy of art. Thus, Art and Intention should be a welcome addition to the library of any aesthetician.Art and Intention comprises seven chapters. The first chapter, reasonably enough, involves a discussion of what it is to be an intention. For Livingston, who follows the action theorist Alfred Mele quite closely, an intention standardly consists of a propositional attitude in addition to a propositional content toward which said attitude is directed. The propositional attitude is executive in nature—that is, where x is the content, the intender is firmly settled upon or committed to perform x, or, at least, to try to perform x. The propositional content of an intention, in turn, is what Livingston calls a plan. An intention then is an executive attitude towards plans.I am a bit unhappy with this formulation, since I worry that it may be somewhat misleading. To my ear, the word plan insinuates the idea of a formulated method, whereas many intentional actions, including those of artists, are scarcely worked out beforehand but emerge instead in the heat of doing things. Livingston is aware of this and appears to require no more of plans in his sense than that they involve at least a rudimentary grasp of the means for carrying off the purposes at hand. This seems right to me, but it still strikes me as strained to call this sort of procedural knowledge a plan.When Jasper Johns denies that he plans to make a picture in a certain way, but rather only follows a thought that pulls in a certain direction, he does not mean to disagree with Livingston, though his choice of words seems at odds with Livingston's.1 For Johns's, like many others, plan means a precise formulation, whereas for the action theorist it is a technical term of art with broader signification. Nevertheless, since the word still retains its ordinary meaning, the possibility for confusion here is rife. So, perhaps another word can be found or, maybe, coined.Chapter 2 concerns intention and the creation of art. Livingston spends the first part of the chapter fending off counterexamples, like automatic writing, that might be adduced to challenge the claim that artworks require intentions. I am very sympathetic with his treatment of the examples he canvasses. However, I would be curious to hear what he would say about a case that I've heard described of a show at MOMA several decades back where images culled from surveillance cameras, operating automatically, were exhibited.2 These specific images were not produced intentionally by anyone. But aren't they art? Perhaps the curators will be assigned the... (shrink)

Dans une lettre adressée à Bertrand Russell, le 17 mai 1905, Hugh MacColl raconte avoir abandonné l’étude de la logique après 1884, pendant près de treize ans, et explique que ce fut la lecture de l’ouvrage de Lewis Carroll, Symbolic Logic (1896), qui ralluma le vieux feu qu’il croyait éteint. Dès lors, il publie de nombreux articles contenant certaines de ses innovations majeures en logique. L’objet de cet article est de discuter la familiarité de MacColl et son appréciation du travail (...) de Carroll, et de comprendre comment cela l’amena à réinvestir le domaine de la logique. Rien n’indique que les deux hommes se soient jamais rencontrés ou aient échangé une correspondance personnelle. Cependant, MacColl recensa dans le journal The Athenaeum plusieurs ouvrages de Carroll, essentiellement en géométrie et en logique. Souvent, Carroll répondait aux critiques de MacColl dans les éditions suivantes de ses ouvrages. Une discussion de ces sources fournit des éclaircissements intéressants sur les investigations mathématiques et logiques de MacColl et Carroll. (shrink)

John Venn and Charles L. Dodgson (Lewis Carroll) created systems of logic diagrams capable of representing classes (sets) and their relations in the form of propositions. Each is a proof method for syllogisms, and Carroll's is a sound and complete system. For a large number of sets, Carroll diagrams are easier to draw because of their self-similarity and algorithmic construction. This regularity makes it easier to locate and thereby to erase cells corresponding with classes destroyed by the premises of an (...) argument, a particularly difficult task in Venn diagrams for more than four sets. Carroll diagrams can represent existential propositions easily, so they are capable of clearly representing more complex problems than Venn's system can. Finally, both Carroll and Venn diagrams are maximal, in the sense that no additional logic information like inclusive disjunctions is able to be represented by them. Carroll's logic diagrams and logic trees constitute his visual logic system. (shrink)

In the period 1893–1897 Charles Dodgson, writing as Lewis Carroll, published two books and two articles on logic topics. Manuscript material first published in 1977 together with letters and diary entries provide evidence that he was working toward a visual proof system for complex syllogistic propositional logic based on a mechanical tree method that he devised.

Following P. F. Strawson, a number of philosophers have argued that if hard incompatibilism is true, then its truth would undermine the justification or value of our relationships with other persons. In this paper, I offer a novel defense of this claim. In particular, I argue that if hard incompatibilism is true, we cannot make sense of: the possibility of promissory obligation, the significance of consent, or the pro tanto wrongness of paternalistic intervention. Because these practices and normative commitments are (...) central to our relationships as we currently conceive of them, it follows that hard incompatibilism has radically revisionary conclusions.

In recent defenses of moral responsibility skepticism, which is the view that no human agents are morally responsible for their actions or character, a number of theorists have argued against Peter Strawson’s (and others’) claim that “the sort of love which two adults can sometimes be said to feel reciprocally, for each other” would be undermined if we were not morally responsible agents. Among them, Derk Pereboom (2001, 2009) and Tamler Sommers (2007, 2012) most forcefully argue against this conception of (...) love. However, in this paper, I plan to defend the claim that there is an essential connection between love and moral responsibility, a thesis I will call love internalism. To begin, I will specify the content and scope of love internalism, and consider ways in which other theorists have attempted to motivate it. I will then consider the various arguments that Pereboom and Sommers advance against love internalism. These arguments, it seems to me, offer us powerful reasons to reject several of the ways in which philosophers have tried to connect moral responsibility to love. Consequently, in light of these criticisms, I will further precisify the content of love internalism. And as we will see, love internalism (as I argue for it) is immune to Pereboom’s and Sommers’ criticisms. Moreover, when its content is sufficiently clarified, love internalism can serve as a plausible premise in an anti-skeptical argument. I thus conclude by arguing that this suitably reformulated statement of love internalism offers a significant challenge to moral responsibility skepticism of the sort Pereboom and Sommers endorse.

Philosophers of science, e.g. Cartwright (1979) and Skyrms (1980), have given accounts of general causation in probabilistic terms; not surprising since we often accept general causal sentences as true despite being aware of apparent counterinstances. Consider:(E1) Smoking is a cause of heart attacks.We accept (E1) as true though aware of smokers who never have a heart attack. Here I quickly review familiar problems in two existing probabilistic accounts, offer a new objection, and suggest the beginnings of an alternative account.The traditional (...) model of general causation maintains that causes, and only causes, raise the probability of the effect That is:(TM) F is a cause of G if and only if.Despite some intuitive appeal, the traditional model faces at least three basic objections. First, consider cases of epiphenomena in which there are properties F, G, and H such that F is a cause of G, F is a cause of H, but G is not a cause of H and H is not a cause of G. (shrink)
