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)

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 $R \vDash \sigma$. Theorem. The theory of a strictly upper triangular n × n matrix ring over an algebraically closed field is ℵ 1 -categorical. (shrink)

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)

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. After identifying the key differences between Interculturalism and Multiculturalism, as well as their many similarities, the authors present an explanatory analysis of this intractable policy challenge. Conservative religious schooling, they argue, tests a conceptual tension inherent in Multiculturalism between (...) respect for group diversity and autonomy, on the one hand, and the ideal of intercultural citizenship, on the other. Taking as a case study Québec's education system and, in particular, recent curricular innovations aimed at helping young people acquire the capabilities of intercultural citizenship, the authors illustrate how Interculturalism signals a compelling way forward in the effort to overcome the political dilemma of conservative religious schooling.

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] .

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 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. My central question deals with the way Fried establishes his rights to things he candidly concedes he does not deserve. 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)

Many of our inherited civic institutions are dead or dying. We need an ambitious reform program to revive democratic life. This essay advances a four-pronged “citizenship agenda”: a campaign finance initiative granting each voter fifty “patriot dollars” to fund candidates and political parties of his or her choice; a proposal for a new national holiday, Deliberation Day, held before each national election, enabling citizens to deliberate on the merits of rival candidates; a system of federally financed electronic news-vouchers to permit (...) professional journalism to survive the destruction of its traditional business model; and a new form of citizenship inheritance, which provides $80,000 to all Americans as they start off life as adults. Working with collaborators, I have developed each of these initiatives at book length. This essay suggests how the “citizenship agenda” yields a whole that is larger than the sum of its parts.

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.

Evidence and theory ranging from traditional philosophy to contemporary cognitive research support the hypothesis that consciousness has a two-part structure: a focused region of articulated experience surrounded by a field of relatively unarticulated, vague experience.William James developed an especially useful phenomenological analysis of this "fringe" of consciousness, but its relation to, and potential value for, the study of cognition has not been explored. I propose strengthening James′ work on the fringe with a functional analysis: fringe experiences work to radically condense (...) context information in consciousness; are vague because a more explicit representation of context information would overwhelm consciousness′ limited articulation capacity; help mediate retrieval functions in consciousness; and contain a subset of monitoring and control experiences that cannot be elaborated in focal attention and are "ineffable." In general, the phenomenology of the fringe is a consequence of its cognitive functions, constrained by consciousness′ limited articulation capacity. Crucial to monitoring and control is the feeling of "rightness." Rightness functions as a summary index of cognitive integration, representing, in the fringe, the degree of positive fit between a given conscious content and its parallel, unconsciously encoded context. Rightness appears analogous to the connectionist metric of global network integration, known variously as goodness-of-fit, harmony, or minimum energy. (shrink)

In two recent papers, Christian List and Philip Pettit have argued that there is a problem in the aggregation of reasoned judgements that is akin to the aggregation of the preference problem in social choice theory. 1 Indeed, List and Pettit prove a new general impossibility theorem for the aggregation of judgements, and provide a propositional interpretation of the social choice problem that suggests it is a special case of their impossibility result. 2 Specifically, they show that no judgement aggregation (...) function for a group is possible if the group seeks to satisfy certain `minimal conditions' designed to ensure that the function is both responsive to the individually rational views of its members and collectively rational in the set of judgements it holds. In this article, I resist the List and Pettit claim that there is the same propensity for collective irrationality or incoherence in the aggregation of reasoned judgements as there is in the aggregation of preference. I argue that reason, because it has a logical structure that is lacking in mere preference, has the effect of giving priority to some aggregations over others, a priority that is not permitted by one of the conditions imposed by List and Pettit. This avoids the incoherence that would otherwise exist if these different aggregations, not consistent with one another, were to compete at the same level of priority. The priority of some aggregations is particularly apparent, I shall argue, if one views the aggregation of judgements through the lens of common law decision-making. Key Words: social choice • judgement • Condorcet jury theorem • collective rationality • public reason • doctrinal paradox • discursive dilemma. (shrink)

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.

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.

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)

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 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)

CRITIQUES OF THEODICIES FOR NATURAL EVIL, DERIVED FROM NATURAL LAWS, SUGGEST TWO REQUIREMENTS THAT A SUCCESSFUL THEODICY PURPORTEDLY MUST SATISFY. REQUIREMENT (1)-- THAT THE THEIST MUST SHOW THAT IT IS CONTRADICTORY OR ABSURD FOR GOD TO INTERVENE IN THE WORLD IN A MIRACULOUS FASHION TO ELIMINATE NATURAL EVIL--IS MET BY SHOWING THAT IT IS IMPOSSIBLE FOR GOD TO CREATE A WORLD GOVERNED BY DIVINE MIRACULOUS INTERVENTION. AS FOR REQUIREMENT (2) -- THAT THE THEIST MUST SHOW THAT IT IS IMPOSSIBLE FOR (...) GOD TO CREATE A SIGNIFICANTLY BETTER WORLD THAN THIS ONE, AND THAT THIS IMPOSSIBILITY DOES NOT CONFLICT WITH DIVINE OMNIPOTENCE--I ARGUE THAT IT NEED NOT BE MET, SINCE IT IS IMPOSSIBLE TO DETERMINE EMPIRICALLY WHETHER THIS IS OR IS NOT THE BEST OF ALL POSSIBLE WORLDS.

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)

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.

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.

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)

I present a general theory for the initial domestication of plants and animals that is based on niche construction theory and incorporates several behavioral ecological concepts, including central-place provisioning, resource catchment, resource ownership and defensibility, and traditional ecological knowledge. This theory provides an alternative to, and replacement for, current explanations, including diet breadth models of optimal foraging theory, that are based on an outmoded concept of asymmetrical adaptation and that attempt to explain domestication as an adaptive response to resource imbalance (...) resulting from either environmental decline or human population growth. The small-scale human societies that first domesticated plants and animals share a number of basic interrelated attributes that when considered as an integrated and coherent set of behaviors provide the context for explaining initial domestication not as an adaptive response to an adverse environmental shift or to human population growth or packing but rather as the result of deliberate human enhancement of resource-rich environments in situations where evidence of resource imbalance is absent.

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 paper discusses the normative ethical theory of the business firm advanced principally by William E. Evan and R. Edward Freeman. According to their stakeholder theory, the firm should be managed for the benefit of its stakeholders: indeed, management has a fiduciary obligation to stakeholders to act as their agent. In this paper I seek to clarify the theory by discussing the concept of a stakeholder and by distinguishing stakeholder theory from two varieties of stockholder theory-I call them ‘pure’ and (...) ‘tinged.’ I argue that the distinctive claims of stakeholder theory, as contrasted with tinged stockholder theories, have been inadequately supported by argument.

I begin by distinguishing four different versions of the argument from evil that start from four different moral premises that in various ways link the existence of God to the absence of suffering. The version of the argument from evil that I defend starts from the premise that if God exists, he would not allow excessive, unnecessary suffering. The argument continues by denying the consequent of this conditional to conclude that God does not exist. I defend the argument against Skeptical (...) Theists who say we are in no position to judge that there is excessive, unnecessary suffering by arguing that this defense has absurd consequences. It allows Young Earthers to construct a parallel argument that concludes that we are in no position to judge that God did not create the earth recently. In the last section I consider whether theists can turn the argument from evil on its head by arguing that God exists. I first criticize Alvin Plantinga’s theory of warrant that one might try to use to argue for God’s existence. I then criticize Richard Swinburne’s Bayesian argument to the same conclusion. I conclude that my version of the argument from evil is a strong argument against the existence of God and that several important responses to it do not defeat it. (shrink)

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 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.

One of the most influential philosophical arguments in favour of the permissibility of abortion is Judith Jarvis Thomson’s violinist analogy, presented in ‘A Defense of Abortion’. Its appeal for pro-choice advocates lies in Thomson’s granting that the fetus is a person with equivalent moral status to any other human being, and yet demonstrating—to those who accept her reasoning—that abortion is still permissible. In her argument, Thomson draws heavily on the parable of the Good Samaritan, arguing that gestating a fetus in (...) some circumstances is what she calls a Good Samaritan act, and claiming that we are not morally required to be Good Samaritans. Here, I argue that Thomson has subverted the parable to justify an action that is the antithesis of its meaning. I contend that Christians are required to be Good Samaritans, and explain that for Christians, this entails abortion is impermissible in all circumstances. Further, I argue that the parable shows the fetus is our neighbour in need of our mercy and assistance, and consequently Christians should be actively involved in helping to ensure the unborn are protected, whether they are fetuses in danger of induced abortion or miscarriage, or surplus frozen embryos.

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)

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 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)

I knew that this was a book a long time in the making, and one that bore the mark of many years of teaching the philosophy discussed in the work.

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)

Sober (1984) presents an account of selection motivated by the view that one property can causally explain the occurrence of another only if the first plays a unique role in the causal production of the second. Sober holds that a causal property will play such a unique role if it is a population level cause of its effect, and on this basis argues that there is selection for a trait T only if T is a population level cause of survival (...) and reproductive success. Sterelny and Kitcher (1988) claim against Sober that some traits directly subject to selection will not satisfy the probabilistic condition on population level causation. In this paper I show that Sober has the resources to resist the Sterelny-Kitcher complaint, but I argue that not all traits that satisfy the probabilistic condition play the required unique role in the production of their effects.

I argue that if deliberation is incompatible with (fore)knowing what one is going to do at the time of the deliberation, then God cannot deliberate. However, this thesis cannot be used to show either that God cannot act intentionally or that human persons cannot deliberate. Further, I have suggested that though omniscience is incompatible with deliberation, it is not incompatible with either some speculation or knowing something on the grounds of inference.

This paper investigates how global coherence is represented in consciousness. It summarizes various lines of research that I have developed over the last twenty years, employing a method that intersects phenomenological with bio-functional analysis. The phenomenological analysis derives from William James's treatment of the fringe, especially a component feeling he called 'right direction'and I call 'rightness'. My bio-functional analysis centres on the limitations of consciousness, and the design strategies that have evolved to finesse these limitations. I argue that fringe phenomenology, (...) in general, has been shaped by its cognitive functions. The function of rightness, in particular, is to represent degrees of fit between a conscious content and the vast body of relevant non-conscious context information. Rightness, then, signals degrees of global positive evaluation. Phenomenologically, rightness is the common element in our feeling that something is a coherent whole: that it is meaningful, correct, fits together, makes sense. It is at the heart of the Aha! experience and, when intense, aesthetic and mystical experience. This analysis also provides a new argument for the efficacy of conscious volition, and a general view of consciousness as a biological information bearing medium. (shrink)
