The most compelling extant accounts of explanation casts all explanations as causal. Yet there are sciences, theoretical population biology in particular, that explain their phenomena by appeal to statistical, non-causal properties of ensembles. I develop a generalised account of explanation. An explanation serves two functions: metaphysical and cognitive. The metaphysical function is discharged by identifying a counterfactually robust invariance relation between explanans event and explanandum. The cognitive function is discharged by providing an appropriate description of this relation. I offer examples (...) of explanations from portfolio theory and population genetics that meet this characterisation. In each case the invariance relation holds between a statistical property of an ensemble and a change in structure of the ensemble. In neither case, however, does the statistical property cause the outcome it explains. There are genuine statistical, non-causal scientific explanations. (shrink)

The aim of this investigation is to explore the role of argumentation schemes in enthymeme reconstruction. This aim is pursued by studying selected cases of incomplete arguments in natural language discourse to see what the requirements are for filling in the unstated premises and conclusions in some systematic and useful way. Some of these cases are best handled using deductive tools, while others respond best to an analysis based on defeasible argumentations schemes. The approach is also shown to work reasonably (...) well for weak arguments, a class of arguments that has always been difficult to analyze without the principle of charity producing a straw man.

Dual-track assessment directs research ethics committees to assess the risks of research interventions based on the unclear distinction between therapeutic and non-therapeutic interventions. The net risks test, in contrast, relies on the clinically familiar method of assessing the risks and benefits of interventions in comparison to the available alternatives and also focuses attention of the RECs on the central challenge of protecting research participants.Research guidelines around the world recognise that clinical research is ethical only when the risks to participants are (...) reasonable.1 Appropriate implementation of this requirement is vital to protecting research participants and allowing research to proceed when it poses acceptable risks. Unfortunately, as the US National Bioethics Advisory Commission notes: “current regulations do not further elaborate how risks and potential benefits are to be assessed, and little additional guidance is available to IRBs.”1The NBAC, as well as numerous commentators, recommend that research ethics committees , ethics review committees and institutional review boards should adopt what may be called dual-track risk assessment.2–5 Yet, dual-track assessment unnecessarily divides research interventions into two different categories before assessing their risks and relies on the unclear distinction between therapeutic and non-therapeutic interventions. As a result, dual-track assessment provides RECs with confusing guidance and has the potential to block valuable research that poses acceptable risks. This paper describes one alternative, the net risks test, and argues that this approach offers a better method for assessing research risks, one that puts RECs in a position to protect participants without blocking appropriate research studies.BACKGROUNDClinical research exposes participants to interventions and procedures to gather systematic data that may be used to improve overall health and well-being. To ensure that research is ethical, RECs must ensure that the risks and burdens to participants are not excessive and that …. (shrink)

Eugenics casts a long shadow over contemporary genetics. Any measure, whether in clinical genetics or biotechnology, which is suspected of eugenic intent is likely to be opposed on that ground. Yet there is little consensus on what this word signifies, and often only a remote connection to the very complex set of social movements which took that name. After a brief historical summary of eugenics, this essay attempts to locate any wrongs inherent in eugenic doctrines. Four candidates are examined and (...) rejected. The moral challenge posed by eugenics for genetics in our own time, I argue, is to achieve social justice. (shrink)

The four principles approach to biomedical ethics (4PBE) has, since the 1970s, been increasingly developed as a universal bioethics method. Despite its wide acceptance and popularity, the 4PBE has received many challenges to its cross-cultural plausibility. This paper first specifies the principles and characteristics of ancient Chinese medical ethics (ACME), then makes a comparison between ACME and the 4PBE with a view to testing out the 4PBE's cross-cultural plausibility when applied to one particular but very extensive and prominent cultural context. (...) The result shows that the concepts of respect for autonomy, non-maleficence, beneficence and justice are clearly identifiable in ACME. Yet, being influenced by certain socio-cultural factors, those applying the 4PBE in Chinese society may tend to adopt a "beneficence-oriented", rather than an "autonomy-oriented" approach, which, in general, is dissimilar to the practice of contemporary Western bioethics, where "autonomy often triumphs".

I have argued in other work that emotion, attentional functions, and executive functions are three interpenetrant global state variables, essentially differential slices of the consciousness pie. This paper will outline the columnar architecture and connectivities of the PAG (periaqueductal gray), its role in organizing prototype states of emotion, and the re-entry of PAG with the extended reticular thalamic activating system (“ERTAS”). At the end we will outline some potential implications of these connectivities for possible functional correlates of PAG networks that (...) are just starting to be mapped. Overall, we will look at many lines of evidence that PAG should be conceptualized as a peri-reticular structure that has a foundational role in emotion, in generating the meaningful organization of behavior by the brain through prototype emotional states, and in allowing the various emotional systems to globally influence and tune both the forebrain and brainstem. Finally, we address implications of these concepts for what is currently understood about consciousness, underlining the need for somewhat more humility within consciousness studies about our current level of understanding of consciousness in the brain, combined with a deeper appreciation of the intrinsic connections between emotion and consciousness. One hopes that more concerted empirical interest in structures underneath the thalamus, combined with a deeper appreciation for the fundamental role that organismic and social value must have in bootstrapping awareness in the developing brain, would begin more widely to influence the fundamental lines of neuroscientific research in both emotion studies and consciousness studies.

In lieu of an abstract, here is a brief excerpt of the content:R. D. Ackerman BELIEVING IN A FICTION: WALLACE STEVENS AT THE LIMITS OF PHENOMENOLOGY The "ring of men" of "Sunday Morning" will chant their "devotion to the sun, / Not as a god, but as a god might be, / Naked among them, like a savage source" (CP, pp. 69-70).' Solar nakedness is deferred even as it is named. The problem for belief is the question of appearance and (...) representation. Things appear as and like.... The phenomenological return to things is also a turn to fiction, as Husserl understood: "If anyone loves a paradox, he can really say... that the element which makes up the life of phenomenology... is fiction. ' " The sun is divine, and it is not; it is both naked and clothed, savage and civilized, source (or end) and means. But such paradox is ultimately unsatisfying, and as we will see with Stevens, the need for belief—for an image or idea of totality—forces the issue of fiction and reality. The Stevens we will have in view is not the Stevens—as if there were such a creature. Our Stevens is the one most persuaded by promises such as those of phenomenology, the one most concerned with decreation (reduction) and fresh beginnings, with discovery and recognition, with imagination, the body, and the earth. This is the Stevens for whom the barrier of language presages at last not absence and difference but fictive recovery of presence and identity, the one for whom poetry represents a way of belief beyond mysticism even as it bodes mythic proximity. Finally, this is the Stevens who predominates throughout the prose (as well as in much of the poetry), who tries mightily to secure a belief while disencumbering himself of metaphysics—but alas, I think, with small success. Although Stevens's association of the problem of belief with the idea of fiction occurs in early poems such as "A High-Toned Old Christian 79 80Philosophy and Literature Woman" and "To the One of Fictive Music," his most intensive involvement with fiction as belief dates from the early 1940s and spans the period of his major essays and his last four volumes of poems. He recounts, for instance, a 1942 conversation with a student: "I said that I thought that we had reached a point at which we could no longer really believe in anything unless we recognized that it was a fiction. The student said that that was an impossibility, that there was no such thing as believing in something that one knew was not true. It is obvious, however, that we are doing that all the time" (L, p. 430). What does it mean to believe in a fiction? That is my main subject here, as we seek out the limits of the phenomenological Stevens. His letters of this period are preoccupied with the problem of fictive belief: "If one no longer believes in God (as truth), it is not possible merely to disbelieve; it becomes necessary to believe in something else.... A good deal of my poetry recently has concerned an identity for that thing.... In one of the short poems that I have just sent to the harvard advocate, I say that one's final belief must be in a fiction. I think that the history of belief will show that it has always been in a fiction" (L, p. 370). The poem referred to, "Asides on the Oboe," begins: The prologues are over. It is a question now, Of final belief. So, say that final belief Must be in a fiction. It is time to choose. (CP, p. 250) Acknowledging that "in the long run, poetry would be the supreme fiction" (L, pp. 430-31), Stevens nonetheless singles out the nominative function of poetry as the essence of its claim to supremacy: "Poetry means not the language of poetry but the thing itself.... The subject matter is what comes to mind when one says of the month of August... 'Thou art not August, unless I make thee so'" (L, p. 377). The quoted line (also from "Asides") underscores the paradox that for Stevens the essence of fiction (the nontrue) is its capacity to nominate the true or the real. This... (shrink)

The main aim of this article is to use the resources of relevant-alternatives contextualism to provide an account of an unrecognized form of epistemic injustice that I call irrelevance-injustice. Irrelevance-injustice occurs either when a speaker raises an alternative that is not taken seriously when it should be, or when a speaker raises an alternative that is taken seriously when it should not be. Irrelevance-injustice influences what alternatives are perceived to be relevant and patterns of knowledge ascriptions in ways that are (...) unfair. Asymmetries in whose alternatives are taken seriously affect how many alternatives members of different groups must rule out prior to being ascribed knowledge. Because knowledge ascriptions have socially valuable functions, asymmetries in whose alternatives are taken seriously mean asymmetries in who gets to do socially valuable things with knowledge ascriptions.

We consider conditionals of the form A ⇒ B where A depends on the future and B on the present and past. We examine models for such conditional arising in Talmudic legal cases. We call such conditionals contrary to time conditionals.Three main aspects will be investigated: Inverse causality from future to past, where a future condition can influence a legal event in the past (this is a man made causality).Comparison with similar features in modern law.New types of temporal logics arising (...) from modelling the Talmudic examples. We shall see that we need a new temporal logic,which we call Talmudic temporal logic with linear open advancing future and parallel changing past, based on two parameters for time. (shrink)

Low birth weight, intrauterine growth retardation, and prematurity are overwhelming risk factors associated with infant mortality and morbidity. The lack of efficacious prenatal screening tests for these three outcomes illuminates the problems inherent in bivariate estimates of association. A biocultural strategy for research is presented, integrating societal and familial levels of analysis with the metabolic, immune, vascular, and neuroendocrine systems of the body. Policy decisions, it is argued, need to be based on this type of biocultural information in order to (...) impact the difficult-to-change problems of low birth weight, intrauterine growth retardation, and prematurity.

Conversational contextualists claim that the truth-conditions of knowledge claims depend upon the dynamics of the conversation in which the knowledge claim is made. However, they have failed to appreciate the ways in which conversational dynamics are influenced by unjust distributions of power. What would the implications be for conversational contextualism if its proponents were not guilty of this oversight? I ask this question for Blome-Tillmann’s presuppositional epistemic contextualism (PEC), perhaps the most sophisticated form of conversational contextualism. The investigation turns up (...) a host of counterintuitive implications of PEC that count against it. I suggest placing moral constraints on conversational dynamics as a way of revising PEC in order to avoid the identified counterintuitive implications. (shrink)
