At some time during the years 398–395 B.C. the people of Rhodes revolted against Sparta, freed themselves from the oppression of the Spartan empire and admitted to their city the Persian fleet commanded by Conon, the Athenian. This fact was overlooked by Xenophon, but reported by Diodorus and Pausanias who quotes Androtion. It seemed, before the discovery of the Hellenica Oxyrhynchia, that the revolt of Rhodes from Sparta was in some way associated with internal party strife, for Xenophon relates that (...) exiled Rhodian oligarchs appealed to Sparta for help in 391 B.C. Such an interrelation between internal politics and foreign policy had, of course, been a feature of Greek political life since the early years of the Peloponnesian War, as Thucydides was not slow to recognize. The discovery of the Hellenica Oxyrhynchia, which devotes a chapter to a democratic revolution at Rhodes in 395 B.C, provided a good deal of new information on the political situation in that city, notably that, contrary to what we might have expected, the revolt from Sparta and the democratic revolution were not contemporaneous. Let us review briefly the details of these two events as far as our information permits. (shrink)

Let n ≥ 3. The following theorems are proved. Theorem. The theory of the class of strictly upper triangular n × n matrix rings over fields is finitely axiomatizable. Theorem. If R is a strictly upper triangular n × n matrix ring over a field K, then there is a recursive map σ from sentences in the language of rings with constants for K into sentences in the language of rings with constants for R such that $K \vDash \varphi$ if (...) and only if $R \vDash \sigma$.

We say that a ring admits elimination of quantifiers, if in the language of rings, {0, 1, +, ·}, the complete theory of R admits elimination of quantifiers. Theorem 1. Let D be a division ring. Then D admits elimination of quantifiers if and only if D is an algebraically closed or finite field. A ring is prime if it satisfies the sentence: ∀ x ∀ y ∃ z (x = 0 ∨ y = 0 ∨ xzy ≠ 0). Theorem (...) 2. If R is a prime ring with an infinite center and R admits elimination of quantifiers, then R is an algebraically closed field. Let A be the class of finite fields. Let B be the class of 2 × 2 matrix rings over a field with a prime number of elements. Let C be the class of rings of the form $GF(p^n) \bigoplus GF(p^k)$ such that either n = k or g.c.d. (n, k) = 1. Let D be the set of ordered pairs (f, Q) where Q is a finite set of primes and f: Q → A ∪ B ∪ C such that the characteristic of the ring f(q) is q. Finally, let E be the class of rings of the form $\bigoplus_{q \in Q}f(q)$ for some (f, Q) in D. Theorem 3. Let R be a finite ring without nonzero trivial ideals. Then R admits elimination of quantifiers if and only if R belongs to E. Theorem 4. Let R be a ring with the descending chain condition of left ideals and without nonzero trivial ideals. Then R admits elimination of quantifiers if and only if R is an algebraically closed field or R belongs to E. In contrast to Theorems 2 and 4, we have Theorem 5. If R is an atomless p-ring, then R is finite, commutative, has no nonzero trivial ideals and admits elimination of quantifiers, but is not prime and does not have the descending chain condition. We also generalize Theorems 1, 2 and 4 to alternative rings. (shrink)

In this essay, Bruce Maxwell, David Waddington, Kevin McDonough, Andrée-Anne Cormier, and Marina Schwimmer compare two competing approaches to social integration policy, Multiculturalism and Interculturalism, from the perspective of the issue of the state funding and regulation of conservative religious schools.

In this article, I take up Marcella Althaus-Reid’s queer strategy that pairs disaffiliation with intimate identification in order to draw out the possibilities and limits of queer strategies of resignification and denaturalization. I will use David M. Halperin’s work on gay femininity, abjection, and camp as the primary site to investigate these queer strategies. This article’s considerations have implications for recent directions taken in contemporary queer theology by challenging projects that presume a certain limitless capacity for queering or that seek (...) to appropriate almost anything – marriage, celibacy, or orthodoxy – as queer. Rather than seeking to mitigate complicity in misogyny or trying to recuperate misogynist theological positions by highlighting their subversive queerness, Althaus-Reid’s demands from queer theologians a prophetic, denunciatory posture that turns away from the imperial theological highways towards the queer ways of knowing and relating to the God at the margins of T-theology.

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.

I argue that the atheological claim that the existence of pain and suffering either contradicts or makes improbable God's existence or his possession of certain critical properties cannot be sustained. The construction of a theodicy for both moral and natural evils is the focus of the central part of the book. In the final chapters I analyze the concept of the best possible world and the properties of goodness and omnipotence insofar as they are predicated of God.

In his recent article Perry Hendricks presents what he calls the impairment argument to show that abortion is immoral. To do so, he argues that to give a fetus fetal alcohol syndrome is immoral. Because killing the fetus impairs it more than giving it fetal alcohol syndrome, Hendricks concludes that killing the fetus must also be immoral. Here, I claim that killing a fetus does not impair it in the way that giving it fetal alcohol syndrome does. By examining the (...) reason why giving a fetus this condition is wrong, I conclude that the same reasoning, on common pro‐choice accounts, does not apply to killing the fetus. Accordingly, Hendricks's argument does not succeed in showing abortion is immoral. (shrink)

Since the introduction of mathematical population genetics, its machinery has shaped our fundamental understanding of natural selection. Selection is taken to occur when differential fitnesses produce differential rates of reproductive success, where fitnesses are understood as parameters in a population genetics model. To understand selection is to understand what these parameter values measure and how differences in them lead to frequency changes. I argue that this traditional view is mistaken. The descriptions of natural selection rendered by population genetics models are (...) in general neither predictive nor explanatory and introduce avoidable conceptual confusions. I conclude that a correct understanding of natural selection requires explicitly causal models of reproductive success. *Received May 2006; revised December 2006. †To contact the author, please write to: Department of Philosophy, Kansas State University, 201 Dickens Hall, Manhattan, KS 66506; e‐mail: [email protected] .

Perry Hendricks has recently presented the impairment argument for the immorality of abortion, to which I responded and he has now replied. The argument is based on the premise that impairing a fetus with fetal alcohol syndrome is immoral, and on the principle that if impairing an organism is immoral, impairing it to a higher degree is also—the impairment principle. If abortion impairs a fetus to a higher degree, then this principle entails abortion is immoral. In my reply, I argued (...) that abortion does not impair an organism in the way fetal alcohol syndrome does, and showed that interest theorists can avoid the argument. Hendricks has responded to my criticisms by demonstrating how abortion does impair an organism. In this reply, I acknowledge Hendricks’ point, but proceed to criticise the application of the impairment principle to abortion, showing that it is invalid if we accept his explanation for why inflicting fetal alcohol syndrome is immoral. I also argue that counter-examples show the impairment principle itself to be dubitable, concluding that the impairment argument remains unpersuasive. (shrink)

Open peer commentary on the article “Constructivism and Mystical Experience” by Hugh Gash.: Gash leverages earlier discussions about the relationship between mysticism and its world, to argue that it is useful in thinking about the unexpected. I argue for a more nuanced understanding of surprise, which leads to asking about the place of questions and of events in cognition.

Heartbeat bills are laws prohibiting abortion in most circumstances once a fetal heartbeat can be detected, and are common in US states. They have been criticised as poorly designed and disingenuous. In this letter to the editor I examine these criticisms.

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.

In a recent article in Religious Studies, Professor P. W. Gooch attempts to wean the orthodox Christian from anthropological materialism by consideration of the question of the nature of the post-mortem person in the resurrection. He argues that the view that the resurrected person is a psychophysical organism who is in some physical sense the same as the ante-mortem person is inconsistent with the Pauline view of the resurrected body; rather, according to him, Paul's view is most consistent with that (...) which affirms the disembodied survival of the person. ‘I want to argue’, he writes, ‘for the thesis that a Pauline resurrection body may well be ontologically the same as a disembodied person.’ I intend to show that Professor Gooch has failed to provide any support for this view and indeed that his own view falls prey to the criticisms which he has raised against other views.

In this paper I consider several versions of the argument from evil against the existence of a God who is omniscient, omnipotent and wholly good and raise some objections to them. Then I offer my own version of the argument from evil that says that if God exists, nothing happens that he should have prevented from happening and that he should have prevented the brutal rape and murder of a certain little girl if he exists. Since it was not prevented, (...) God does not exist. My conclusion rests on the claim that no outweighing good was served by allowing that murder, or any other instance of comparable evil, to occur. I take up the objection that my argument moves illicitly from apparently pointless suffering to the claim that there is reason to believe that there is pointless suffering. I offer an example to show that the existence of apparently pointless suffering counts to some extent against the existence of God and to show that no basic belief that God exists that rests on certain sorts of grounds can remain justified in the face of apparently pointless suffering.

The substance view is an account of personhood that regards all human beings as possessing instrinsic value and moral status equivalent to that of an adult human being. Consequently, substance view proponents typically regard abortion as impermissible in most circumstances. The substance view, however, has difficulty accounting for certain intuitions regarding the badness of death for embryos and fetuses, and the wrongness of killing them. Jeff McMahan’s time-relative interest account is designed to cater for such intuitions, and so I present (...) a proposal for strengthening the substance view by incorporating McMahan’s account – the Dual-Aspect Account of the morality of killing. I show that it resolves some important issues for the substance view while preserving its central premise of moral equality for all human beings. I then compare the Dual-Aspect Account with McMahan’s Two-Tiered Account of the morality of killing, which he derives from his time-relative interest account. (shrink)

I hope to persuade Charles Fried to think again about his developing views on distributive justice. Since I live at a certain remove from Cambridge, the best I can offer is a hypothetical dialogue with an imaginary person whose views seem, to me at least, of a Friedian inspiration.

To present my problems, I shall begin with a simpler case than (...) those – involving kidneys and talents – that Fried makes central to his discussion. Rather than starting with these rather special goods, I find it clarifying to focus first on more garden variety commodities – which, to emphasize their character, I shall call apples. (shrink)

Genome editing is revolutionising the field of genetics, which includes novel applications to food animals. Responsible research and innovation has been advocated as a way of ensuring that a wider-range of stakeholders and publics are able to engage with new and emerging technologies to inform decision making from their perspectives and values. We posit that genome editing is now proceeding at such a fast rate, and in so many different directions, such as to overwhelm attempts to achieving a more reflective (...) pace. An alternative location for reflection is during the much slower process of taking products from the lab to market. We suggest emphasising Responsible Innovation, putting the ‘I’ back into RRI, and encouraging companies to embrace an RRI approach. We review some previous attempts at developing industry-relevant frameworks for RRI. We then describe two examples of genome editing in livestock; hornless cattle and disease resistant pigs, and reflect on the sorts of questions that could be considered in these two genome editing examples. This paper seeks to take forward the discussion on RRI by extending it to bringing products to market in the context of genome edited livestock. (shrink)

After preparing the way with comments on evanescent quantities and then Newton’s interpretation of his second law, this study of Proposition II (Book I)— Proposition II Every body that moves in some curved line described in a plane and, by a radius drawn to a point, either unmoving or moving uniformly forward with a rectilinear motion, describes areas around that point proportional to the times, is urged by a centripetal force tending toward that same point. —asks and answers the following (...) questions: When does a version of Proposition II first appear in Newton’s work? What revisions bring that initial version to the final form in the 1726 Principia? What, exactly, does this proposition assert? In particular, what does Newton mean by the motion of a body “urged by a centripetal force”? Does it assert a true mathematical claim? If not, what revision makes it true? Does the demonstration of Proposition II persuade? Is it as convincing, for example, as the most convincing arguments of the Principia? If not, what revisions would make the demonstration more persuasive? What is the importance of Proposition II, to the physics of Book III and the mathematics of Book I? (shrink)

I first discuss the Buddhist concept of the self as lying between nihilism and substantialism, understood in terms of sets of skandhas and later momentariness. I then discuss the role of karma as a causal nexus that brings the skandhas into a state of co-ordination and whether this role is subjective or objective. Finally, I discuss the import of this view that there is no substantial self but only momentary events of various discrete sorts on the meaning and possibility of (...) life after death and the rootedness of the law of karma in justice. Finally, I consider the implications of this for rebirth and nirvana. (shrink)

How important is the concept of solidarity in our society's calculus of consent as regards the legitimacy and ethical and political support for public health, health policy, and health services? By the term “calculus of consent,” we refer to the answer that people give to rationalize and justify their obedience to laws, rules, and policies that benefit others. The calculus of consent answers questions such as, Why should I care? Why should I help? Why should I contribute to the public (...) provision of others? Consent here does not have to be a deliberate, explicit act of informed agreement. And a calculus does not have to be a quantifiable, quasimathematical operation; more often, such a calculus takes narrative form in stories that a society tells about itself and that individuals tell about their place in it. One vital function of bioethics is to inform and shape those stories. Bioethics has the potential to offer society a keener insight into and perception of what is ethically at stake in controversies concerning health, science, and society. This insight is what we shall refer to as a “moral imagination,” by which we do not mean make-believe or fantasy but, rather, the capacity to take a critical distance from the given, to think reality otherwise. The moral imagination enables one to see connections between factors at work in history, in large social and communal structures, and in the shape of one's own life, thoughts, and feelings. Here we are especially concerned with the contribution that the concept of solidarity can make to the moral imagination of bioethics. We contend that solidarity must become more widely active and explicit in bioethics analysis and argumentation as it endeavors to shape reasons for obeying norms and rules of common benefit in an open, diverse society.

Ample research links mothers’ postpartum depression (PPD) to adverse interactions with their infants. However, most studies relied on general population samples, whereas a substantial number of women are at elevated depression risk. The purpose of this study was to describe mothers’ interactions with their 6- and 12-month-old infants among women at elevated risk, although with a range of symptom severity. We also identified higher-order factors that best characterized the interactions and tested longitudinal consistency of these factors from 6 to 12 (...) months of infant age. We leveraged data from eight projects across the United States (n = 647), using standardized depression measures and an adaptation of the NICHD Mother-Infant Interaction Scales. Overall, these depression-vulnerable mothers showed high levels of sensitivity and positive regard and low levels of intrusiveness, detachment, and negative regard with their infants. Factor analyses of maternal behaviors identified two overarching factors—“positive engagement” and “negative intrusiveness” that were comparable at 6 and 12 months of infant age. Mothers’ ability to regulate depressed mood was a key behavior that defined “positive engagement” in factor loadings. An exceptionally strong loading of intrusiveness on the second factor suggested its central importance for women at elevated depression risk. Mothers with severe depressive symptoms had significantly more “negative intrusiveness” and less “positive engagement” with their 6-month-old infants than women with moderate or fewer depressive symptoms, suggesting a potential tipping point at which symptoms may interfere with the quality of care. Results provide the foundation for further research into predictors and moderators of women’s interactions with their infant among women at elevated risk for PPD. They also indicate a need for evidence-based interventions that can support more severely depressed women in providing optimal care. (shrink)

At first glance, atheism seems simple to define. If atheism is the negation of theism, and if theism is the view that at least one god exists, then atheism is the negation of this view. However, the common definitions that follow from this insight suffer from two problems: first, they often leave undefined what “god” means, and, second, they understate the scope of the disagreement between theists and atheists, which often has as much to do with the fundamental character of (...) reality as with the existence of one being in it. Some writers address the second problem by reinterpreting atheism as the logical consequence of particular metaphysical views, such as naturalism or physicalism, which are then taken as the true meaning of atheism. These interpretations, though more satisfactory in some respects, can result in concepts of atheism that are unclear or too narrow, and they often still leave “god” undefined. In this paper, I propose that atheism be defined as the proposition that reality is solely an impersonal order. Theism is the proposition that reality is not solely an impersonal order, being either a personal order, that is, an order founded by at least one person, or an impersonal order plus at least one transcendent person. A god is a person who is not subject to the laws governing that order and thus transcends it. I explain these definitions and briefly discuss some of their implications. First I survey prior definitions of atheism to display the problems they raise. (shrink)

This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical (...) evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated. (shrink)

In this paper I will argue that, in general, where the evidence supports two theories equally, the simpler theory is not more likely to be true and is not likely to be nearer the truth. In other words simplicity does not tell us anything about model bias. Our preference for simpler theories (apart from their obvious pragmatic advantages) can be explained by the facts that humans are known to elaborate unsuccessful theories rather than attempt a thorough revision and that a (...) fixed set of data can only justify adjusting a certain number of parameters to a limited degree of precision. No extra tendency towards simplicity in the natural world is necessary to explain our preference for simpler theories. Thus Occam's razor eliminates itself (when interpreted in this form). (shrink)

History's judgment on the success of bioethics will not depend solely on the conceptual creativity and innovation in the field at the level of ethical and political theory, but this intellectual work is not insignificant. One important new development is what I shall refer to as the relational turn in bioethics. This development represents a renewed emphasis on the ideographic approach, which interprets the meaning of right and wrong in human actions as they are inscribed in social and cultural practices (...) and in structures of lived meaning and interdependence; in an ideographic approach, the task of bioethics is to bring practice into theory, not the other way around. The relational turn in bioethics may profoundly affect the critical questions that the field asks and the ethical guidance it offers society, politics, and policy. The relational turn provides a way of correcting the excessive atomism of many individualistic perspectives that have been, and continue to be, influential in bioethics. Nonetheless, I would argue that most of the work reflecting the relational turn remains distinctively liberal in its respect for the ethical significance of the human individual. It moves away from individualism, but not from the value of individuality.In this review essay, I shall focus on how the relational turn has manifested itself in work on core concepts in bioethics, especially liberty and autonomy. Following a general review, I conclude with a brief consideration of two important recent books in this area: Jennifer Nedelsky's Law's Relations and Rachel Haliburton's Autonomy and the Situated Self.

Philosophers writing on the subject of human action have found it tempting to introduce their subject by raising Wittgenstein's question, 'What is left over if you subtract the fact that my arm goes up from the fact that I raise my arm?' The presumption is that something of particular interest is involved in an action of raising an arm that is not present in a mere bodily movement, and the philosopher's task is to specify just what this is. Unfortunately, such (...) an approach does not take us very far, since a person could properly be said to raise his (or her) arm while asleep or hypnotized even though he (or she) would not be performing an action in the sense of 'action' with which philosophers are particularly concerned. To avoid this kind of difficulty I shall approach the subject of human action is a more academic way: I shall expound some important rival theories of human action, and introduce the relevant issues by commenting critically on those theories. One of the issues I eventually introduce is a metaphysical one. A theory of action makes sense, I contend, only on the assumption that there are such 'things' as actions (or events). After considering some key arguments bearing on the issue I conclude that, as matters currently stand in philosophy, a metaphysically noncommittal attitude toward actions and events seems justified.

Abstract:In the following essay I attempt a Schellingian response to the question of what it means to do philosophy in anticipation of civilizational collapse and the end of nature as we know it. As early as 1804 Schelling foresees how the spirit of modernity would lead to what he called “the annihilation of Nature,” but he also advanced a host of ideas that speak directly to our current dilemma. Most importantly for our purposes he held that every significant idea is (...) always as ethical as it is metaphysical: “the highest speculative concepts” must always be “simultaneously the most profound ethical concepts” (II, 3, 67). Ontology, epistemology, logic, aesthetics must all be understood ethically, a point which is seen most clearly in the demand for thoroughgoing systematic unity: the highest speculative concept of unity that must be informed by the most profound ethical experience of the unity of nature which alone can sanctify the positive meaning philosophy must engender if it is to transform human consciousness by increasing awareness of our nature as nature. Such a transformed awareness founds his call for a new way of thinking and doing philosophy that would be as different from the modern as the modern was from the ancient; as ancient referred to the past and, etymologically ‘modern’ denotes the present, he argues for a new way of thinking directed by the ethical tense of the future, in which the absolute becomes the future understood as that which should be (das Seinsollende). To anticipate, I posit the normativity of nature which, as the sustainer of the relational web of the living world, supplies the absolute value to orient humanity’s future. This requires an ecstatic ontology as well as an ethics and epistemology which unite in an erotics of the earth that, by integrating the immediate and sensuous reality of living nature, opens us to a more dynamic way of doing philosophy; one whose primary mode is more haptic than ocular, working by feeling and touch more than abstraction and sight, as it returns love to wisdom and elevates the future to determine the present.

I argue that results from foraging theory give us good reason to think some evolutionary phenomena are indeterministic and hence that evolutionary theory must be probabilistic. Foraging theory implies that random search is sometimes selectively advantageous, and experimental work suggests that it is employed by a variety of organisms. There are reasons to think such search will sometimes be genuinely indeterministic. If it is, then individual reproductive success will also be indeterministic, and so too will frequency change in populations of (...) organisms employing such search. (shrink)

bruce@edmonds.name http://bruce.edmonds.name Abstract. Two kinds of problem are distinguished: the first of finding processes which produce complex outcomes from the interaction of simple parts, and the second of finding which process resulted in an observed complex outcome. The former I call the easy complexity problem and the later the hard complexity problem. It is often assumed that progress with the easy problem will aid process with the hard problem. However this assumes that the “reverse engineering” problem, of determining (...) the process from the outcomes is feasible. Taking a couple of simple models of reverse engineering, I show that this task is infeasible in the general case. Hence it cannot be assumed that reverse engineering is possible, and hence that most of the time progress on the easy problem will not help with the hard problem unless there are special properties of a particular set of processes that make it feasible. Assuming that complexity science is not merely an academic “game” and given the analysis of this paper, some criteria for the kinds of paper that have a reasonable chance of being eventually useful for understanding observed complex systems are outlined. Many complexity papers do not fare well against these critieria. (shrink)

I respond to Jonathan Chimakonam’s paper in which he presents an approach to dialogue in philosophical space, and raises questions about my own approach. I raise four questions to his understanding of conversation. First, I ask him for more details on his conception of conversation.

And fourth, how does wonder fit into conversation in and about place?

Experts play an important role in society, but there has been little investigation about the nature of expertise. I argue that there are two kinds of experts: those whose expertise is a function of what theyknow (epistemic expertise), or what theydo (performative expertise). Epistemic expertise is the capacity to provide strong justifications for a range of propositions in a domain, while performative expertise is the capacity to perform a skill well according to the rules and virtues of a practice. Both (...) epistemic and performative experts may legitimately disagree with one another, and the two senses are conceptually and logically distinct. (shrink)

Benjamin Zolf, in his recent paper ‘No conscientious objection without normative justification: Against conscientious objection in medicine’, attempts to establish that in order to rule out arbitrary conscientious objections, a reasonability constraint is necessary. This, he contends, requires normative justification, and the subjective beliefs that ground conscientious objections cannot easily be judged by normative criteria. Zolf shows that the alternative of using extrinsic criteria, such as requiring that unjustified harm must not be caused, are likewise grounded on normative criteria. He (...) concludes that conscientious objection is therefore untenable. Here, I present an alternative account, based on the value we are willing to place on conscientious objection as an expression of freedom of conscience and religion. Using an extrinsic criterion such as harm, we can make a judgement of what degree of harm should be tolerated as the cost of permitting conscientious objection. A normative criterion for judging individual claims is therefore not required. (shrink)

I argue that the orthodox account of probabilistic causation, on which probabilistic causes determine the probability of their effects, is inconsistent with certain ontological assumptions implicit in scientific practice. In particular, scientists recognize the possibility that properties of populations can cause the behavior of members of the populations. Such emergent population‐level causation is metaphysically impossible on the orthodoxy.
