We propose using a bi-axial map as a heuristic for categorizing different dynamics involved in the relationship between quality and popularity. The east–west axis represents the degree to which an agent’s decision is influenced by those of other agents. This ranges from the extreme western edge, where an agent learns individually (no outside influence), to the extreme eastern edge, where an agent is influenced by a large number of other agents. The vertical axis represents how easy or difficult it is (...) for an agent to discern the relative quality of available choices. When a case study is located on the map, it becomes easier to select the range of tools to use for understanding and predicting the relation between quality and popularity. (shrink)
Although the beliefs, preferences, and constraints (BPC) model may account for individuals independently making simple decisions, it becomes less useful the more complex the social setting and the decisions themselves become. Perhaps rather than seek to unify their field under one model, behavioral scientists could explore when and why the BPC model generally applies versus fails to apply as a null hypothesis.

This paper investigates whether there is a discrepancy between the stated and actual aims in biomechanical research, particularly with respect to hypothesis testing. We present an analysis of one hundred papers recently published in The Journal of Experimental Biology and Journal of Biomechanics, and examine the prevalence of papers which (a) have hypothesis testing as a stated aim, (b) contain hypothesis testing claims that appear to be purely presentational (i.e. which seem not to have influenced the actual study), and (c) (...) have exploration as a stated aim. We found that whereas no papers had exploration as a stated aim, 58% of papers had hypothesis testing as a stated aim. We had strong suspicions, at the bare minimum, that presentational hypotheses were present in 31% of the papers in this latter group. (shrink)
Ostriches were filmed running at maximum speed, and forces on the feet were calculated. Measurements were made of the principal structures in the legs of an ostrich. Hence peak stresses in muscles, tendons and bones were calculated. They lay within the range of stresses calculated for strenuous activities of other vertebrates. The ostrich makes substantial savings of energy in running, by elastic storage in stretched tendons. Pachyornis was a flightless bird, much heavier than ostriches and with massively thick leg bones. (...) These bones are shorter than predicted for its estimated body mass, by extrapolation from allometric equations for flying birds. An attempt is made to calculate the stresses that acted in the leg bones in running, for all possible patterns of leg movement. The stresses were probably rather low, unless Pachyornis was capable of running fast. It is argued that the optimum factor of safety for moo leg bones may have been exceptionally high, as a consequence of the absence of predators. (shrink)
Contemporary appeals for a deepening of civic friendship in liberal democracies often draw on Aristotle. This paper warns against a certain kind of attempt to use Aristotle in our own theorising, namely accounts of civic friendship that characterise it as similar in some way to Aristotelian virtue friendship. The most prominent of these attempts have focused on disinterested mutual regard as a basic ingredient in all Aristotelian forms of friendship. The argument against this is that it inadequately accounts for the (...) idea of a virtue friend as another self, which we find in Aristotle’s thought. When we attend closely to that, we see that civic friendship is different in a fundamental way from virtue friendship because virtue friends are keenly committed to the moral improvement of one another. It is argued that Aristotle does not see civic friendship in the same way. However, if this argument about the differences between the forms of friendship cannot be accepted, the paper argues that we should not draw on Aristotle for an understanding of civic friendship because any similarity it might have to virtue friendship would license illiberal interventions in the lives of citizens in service of some idea of moral improvement. A seeming connection between Aristotelian civic friendship and thick conceptions of citizenship is replaced with a connection between it and thinner conceptions. (shrink)
High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)
Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

Group selection is increasingly being viewed as an important force in human evolution. This paper examines the views of R.D. Alexander, one of the most influential thinkers about human behavior from an evolutionary perspective, on the subject of group selection. Alexander's general conception of evolution is based on the gene-centered approach of G.C. Williams, but he has also emphasized a potential role for group selection in the evolution of individual genomes and in human evolution. Alexander's views are (...) internally inconsistent and underestimate the importance of group selection. Specific themes that Alexander has developed in his account of human evolution are important but are best understood within the framework of multilevel selection theory. From this perspective, Alexander's views on moral systems are not the radical departure from conventional views that he claims, but remain radical in another way more compatible with conventional views.

“Ex nihilo nihil fit,” goes the classic adage: nothing comes from nothing. Parmenides used the Principle of Sufficient Reason to argue that there was no such thing as change: If there was change, why did it happen when it happened rather than earlier or later? “Nothing happens in vain, but everything for a reason and under necessitation,” claimed Leucippus. Saint Thomas insisted in the..
It is widely accepted that divine creation of human beings is compatible with evolutionary theory, except perhaps in regard of the human soul, and that neo-Darwinian evolutionary theory provides an explanation of speciation and of complex features of organisms that undercuts Paley-style teleological arguments, whether or not the evolutionary mechanisms are truly random or deterministic. I will argue that a plausible understanding of the doctrine of creation of human beings is either logically or rationally incompatible with full evolutionary theory, even (...) if one does not take souls into account. Consequently, a theist needs to move to a weaker version either of the creation doctrine or of evolutionary theory, or both. (shrink)

The production of a number of vaccines involves the use of cell-lines originally derived from fetuses directly aborted in the 1960s and 1970s. Such cell-lines, indeed sometimes the very same ones, are important to on-going research, including at Catholic institutions. The cells currently used are removed by a number of decades and by a significant number of cellular generations from the original cells. Moreover, the original cells extracted from the bodies of the aborted fetuses were transformed to produce the cell (...) lines, since otherwise they would be incapable of the kind of culturing that is required.

I argue that an examination of the analogy between the notion of a bug and that of a genetic defect supports an analogy not just between a computer program and DNA, but between a computer program designed by a programmer and DNA. This provides an analogical teleological argument for the existence of a highly intelligent designer.
The cosmos is filled with evil that seemingly has no redeeming value. Granted, some evils do lead to greater goods, sometimes goods that could not exist without the evils. Thus, the exercise of courage is a good that requires either an actual evil to stand firm in the face of or the illusion of an evil—and an illusion is a kind of evil, too. But many evils appear to serve no such purpose. Philosophers call an evil that a supremely good (...) God would have insufficient reason to permit to exist a gratuitous evil. A particularly powerful form of the argument from evil against the existence of the God of Western monotheism is, thus, that there.. (shrink)
I argue that standard functionalism leads to absurd conclusions as to the number of minds that would exist in the universe if persons were duplicated. Rather than yielding the conclusion that making a molecule-by-molecule copy of a material person would result in two persons, it leads to the conclusion that three persons, or perhaps only one person, would result. This is absurd and standard functionalism should be abandoned. Social varieties of functionalism fare no better, though there is an Aristotelian variety (...) of functionalism that accepts irreducible finality that escapes this particular reductio. (shrink)
The Principle of Sufficient Reason (PSR) says that all contingent facts must have explanation. In this volume, the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument and Peter (...) van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics. (shrink)
Two texts that raise problems for Alexander of Aphrodisias' theory of universals are examined. "De anima" 90.2-8 appears to suggest that universals are dependent on thought for their existence; this raises questions about the status both of universals and of forms. It is suggested that the passage is best interpreted as indicating that universals are dependent on thought only for their being recognised as universals. The last sentence of "Quaestio" 1.11 seems to assert that if the universal did not (...) exist no individual would exist, thereby contradicting Alexander's position elsewhere. This seems to be a slip resulting from the fact that species with only one member are the exception rather than the rule. (shrink)

Although metaphysics as a discipline can hardly be separated from Aristotle and his works, the questions it raises were certainly known to authors even before the reception of Aristotle in the thirteenth century. Even without the explicit use of this term the twelfth century manifested a strong interest in metaphysical questions under the guise of «natural philosophy» or «divine science», leading M.-D. Chenu to coin the expression of a twelfth century «éveil métaphysique». In their commentaries on Boethius and under the (...) influence of Neoplatonism, twelfth century authors not only anticipate essential elements of thirteenth century metaphysics, they also make an original contribution to the history of metaphysics by attempting to integrate the theory of first principles, philosophical theology and ontology.

Metaethics is a perennially popular subject, but one that can be challenging to study and teach. As it consists in an array of questions about ethics, it is really a mix of (at least) applied metaphysics, epistemology, philosophy of language, and mind. The seminal texts therefore arise out of, and often assume competence with, a variety of different literatures. It can be taught thematically, but this sample syllabus offers a dialectical approach, focused on metaphysical debate over moral realism, which spans (...) the century of debate launched and framed by G. E. Moore's Principia Ethica. The territory and literature are, however, vast. So, this syllabus is highly selective. A thorough metaethics course might also include more topical examination of moral supervenience, moral motivation, moral epistemology, and the rational authority of morality. Authors Recommend: Alexander Miller, An Introduction to Contemporary Metaethics (Cambridge: Polity Press, 2003). This is one of the few clear, accessible, and comprehensive surveys of the subject, written by someone sympathetic with moral naturalism. David Brink, Moral Realism and the Foundations of Ethics (Cambridge: Cambridge University Press, 1989). Brink rehabilitates naturalism about moral facts by employing a causal semantics and natural kinds model of moral thought and discourse. Michael Smith, The Moral Problem (Oxford: Blackwell, 1994). Smith's book frames the debate as driven by a tension between the objectivity of morality and its practical role, offering a solution in terms of a response-dependent account of practical rationality. Gilbert Harman and Judith Jarvis Thomson, Moral Relativism & Moral Objectivity (Cambridge, MA: Blackwell, 1996). Harman argues against the objectivity of moral value, while Thomson defends it. Each then responds to the other. Frank Jackson, From Metaphysics to Ethics (Oxford: Clarendon Press, 1998). Jackson argues that reductive conceptual analysis is possible in ethics, offering a unique naturalistic account of moral properties and facts. Mark Timmons, Morality without Foundations (Oxford: Oxford University Press, 1999). Timmons distinguishes moral cognitivism from moral realism, interpreting moral judgments as beliefs that have cognitive content but do not describe moral reality. He also provides a particularly illuminating discussion of nonanalytic naturalism. Philippa Foot, Natural Goodness (New York, NY: Oxford University Press, 2001). A Neo-Aristotelian perspective: moral facts are natural facts about the proper functioning of human beings. Russ Shafer-Landau, Moral Realism: A Defence (New York, NY: Oxford University Press, 2003). In this recent defense of a Moorean, nonnaturalist position, Shafer-Landau engages rival positions in a remarkably thorough manner. Terence Cuneo, The Normative Web (New York, NY: Oxford University Press, 2007). Cuneo argues for a robust version of moral realism, developing a parity argument based on the similarities between epistemic and moral facts. Mark Schroeder, Slaves of the Passions (New York, NY: Oxford University Press, 2007).

The Principle of Sufficient Reason (PSR) says that, necessarily, every contingently true proposition has an explanation. The PSR is the most controversial premise in the cosmological argument for the existence of God. It is likely that one reason why a number of philosophers reject the PSR is that they think there are conceptual counter-examples to it. For instance, they may think, with Peter van Inwagen, that the conjunction of all contingent propositions cannot have an explanation, or they may believe that (...) quantum mechanical phenomena cannot be explained. It may, however, be that these philosophers would be open to accepting a restricted version of the PSR as long as it was not ad hoc. I present a natural restricted version of the PSR that avoids all conceptual counter-examples, and yet that is strong enough to ground a cosmological argument. The restricted PSR says that all explainable true propositions have explanations. (Published Online April 21 2004). (shrink)
We will give a new cosmological argument for the existence of a being who, although not proved to be the absolutely perfect God of the great Medieval theists, also is capable of playing the role in the lives of working theists of a being that is a suitable object of worship, adoration, love, respect, and obedience. Unlike the absolutely perfect God, the God whose necessary existence is established by our argument will not be shown to essentially have the divine perfections (...) of omnipotence, omniscience, omnibenevolence, and sovereignty. Furthermore, it is not even shown that he is contingently omnipotent and omniscient, just powerful and intelligent enough to be the supernatural designer-creator of the exceedingly complex and wondrous cosmos that in fact..

          I am going to give an argument showing that abortion is wrong in exactly the same circumstances in which it is wrong to kill an adult. To argue further that abortion is always wrong would require showing that it is always wrong to kill an adult or that the circumstances in which it is not wrong--say, capital punishment--never befall a fetus. Such an argument will be beyond the scope of this (...) paper, but since it is uncontroversial that it is wrong to kill an adult human being for the sorts of reasons for which most abortions are performed, it follows that most abortions are wrong.           The argument has three parts, of decreasing difficulty. The most difficult will be the first part where I will argue that I was once a fetus and before that I was an embryo. This argument will rest on simple considerations of the metaphysics of identity. The next part of the argument will be to show that it would have been at least as wrong to have killed me before I was born as it would be to kill me now. I will argue for this in more than one way, but the guiding intuition is clear: if you kill me earlier, the victim is the same but the harm is greater since I am deprived of more the earlier I die. Finally, the easiest part of the argument will be that I am not relevantly different from anybody else and the fetus which I was was not relevantly different from any other human fetus, and so the argument applies equally well to all fetuses.           The advantage of this argument over others is that it avoids talking of personhood, except in one of the independent arguments in part 2.

Substantive theories of diachronic identity have been offered for different kinds of entities. The kind of entity whose diachronic identity has received the most attention in the literature is person, where such theories as the psychological theory, the body theory, the soul theory, and animalism have been defended. At the same time, Wittgenstein's remark that ?to say of two things that they are identical is nonsense, and to say of one thing that it is identical with itself is to say (...) nothing at all? suggests that the idea of further analysing identity is mistaken at root. I shall offer a simple, deflationary theory that reduces diachronic identity to quantification, synchronic identity and existence at a spacetime location (or at a time, for non-spatial entities). On logical grounds, the theory is guaranteed to have no counterexamples. Because the theory is guaranteed to have no counterexamples, all the imaginative examples offered as intuitive support for theories of personal identity are going to be either incorrect or compatible with the theory. I shall argue that the deflationary theory is preferable on simplicity grounds to typical substantive theories, and that various problems that are commonly thought to concern diachronic identity are better seen as about something else.

The paper discusses the sense in which the changes undergone by normative economics in the twentieth century can be said to be progressive. A simple criterion is proposed to decide whether a sequence of normative theories is progressive. This criterion is put to use on the historical transition from the new welfare economics to social choice theory. The paper reconstructs this classic case, and eventually concludes that the latter theory was progressive compared with the former. It also briefly comments on (...) the recent developments in normative economics and their connection with the previous two stages.

Our paper ‘A new cosmological argument’ gave an argument for the existence of God making use of the weak Principle of Sufficient Reason (W-PSR) which states that for every proposition p, if p is true, then it is possible that there is an explanation for p. Recently, Graham Oppy, as well as Kevin Davey and Rob Clifton, have criticized the argument. We reply to these criticisms. The most interesting kind of criticism in both papers alleges that the W-PSR can be (...) justifiably denied by the atheist, and constitutes no improvement on the strong Principle of Sufficient Reason (S-PSR) which claims that every true proposition in fact has an explanation. The criticism is predicated on the fact that it can be shown that the W-PSR entails the S-PSR. We argue that the W-PSR's plausibility remains despite the criticisms. From this it can be seen to follow that the entailment relation between the W-PSR and the S-PSR gives one reason to believe the S-PSR. (shrink)
The A-theory of time says that it is an objective, non-perspectival fact about the world that some events are present , while others were present or will be present. I shall argue that the A-theory has some implausible consequences for inductive reasoning. In particular, the presentist version of the A-theory, which holds that the difference between the present and the non-present consists in the present events being the only ones that exist, is very much in trouble.
An omnipotent being would be a being whose power was unlimited. The power of human beings is limited in two distinct ways: we are limited with respect to our freedom of will, and we are limited in our ability to execute what we have willed. These two distinct sources of limitation suggest a simple definition of omnipotence: an omnipotent being is one that has both perfect freedom of will and perfect efficacy of will. In this paper we further explicate this (...) definition and show that it escapes the standard objections to divine omnipotence. (shrink)
McGrew, McGrew and Vestrup (MMV) have argued that the fine-tuning anthropic principle argument for the existence of God fails because no probabilities can be assigned to the likelihood that physical constants fall in some finite interval. In particular, the fine-tuning argument that, say, some constant must lie in the range (1.000,1.001) in order for intelligent life to be possible is no better than a seemingly absurd coarse-tuning argument based on the need for that constant to lie in the range (0.001, (...) 10000000). The author of this piece defends the coarse tuning argument as a rational piece of reasoning, and, further, argues that the countable additivity assumption in the MMV paper can be dropped in favor of finite additivity.

According to David Lewis's extreme modal realism, every waythat a world could be is a way that some concretely existingphysical world really is. But if the worlds are physicalentities, then there should be a set of all worlds, whereasI show that in fact the collection of all possible worlds is nota set. The latter conclusion remains true even outside of theLewisian framework.
David Lewis (1979) has argued that according to his possible worlds analysis of counterfactuals, “backtracking” counterfactuals of the form “If event A were to happen at tA, then event B would happen at tB” where tB precedes tA, are usually false if B does not actually happen at tB. On the other..
A recombinationist like the earlier Armstrong (1989) claims that logically possible worlds are recombinations of items found in the actual world, with some items reduplicated if need be and others deleted. An immediate consequence of this is that if an alien property is a property that could only be defined in terms of fundamental properties that are actually uninstantiated, then it is logically impossible that an alien property be instantiated as no recombination of the items in the actual world can (...) yield a world with an entity having such a property. Recombinationism immediately implies that S5 is false. To see this, suppose for simplicity, as I will throughout this paper, that electric charge is a fundamental property--otherwise, a different example would have to be used. Then, let w be a possible world lacking any charged objects. At w, then, it is true that it is logically impossible that there be a charged particle since no recombination of the entities in w yields a charged particle. Therefore, contrary to S5, what is possible at w differs from what is possible at the actual world, since charged particles are actual and hence logically possible at the actual world. While this argument may make one sceptical of recombinationism, the recombinationist will say that it is not surprising that if we follow out the Aristotelian intuition that possibility is to be grounded in actually existing entities, then what is possible will depend on what is actual. Henceforth I will no longer assume S5, and so logical possibilities will have to be relativized to worlds if recombinationism is true: it is logically possible at the actual world for charged particles to exist, but at a world at which there are no charged particles it is logically impossible for charged particles to exist...

I offer examples showing that, pace G. E. Moore, it is possible to assert ?Q and I don't believe that Q? sincerely, truly, and without any absurdity. The examples also refute the following principles: (a) justification to assert p entails justification to assert that one believes p (Gareth Evans); (b) the sincerity condition on assertion is that one believes what one says (John Searle); and (c) to assert (to someone) something that one believes to be false is to lie (Don (...) Fallis). (shrink)
In simplified form, the argument that I am defending holds that the incompatibility of our freedom with determinism follows from the conjunction of (1) a plausible supervenience claim which says that whether a human agent is free depends only on what happens during the agent’s life and (2) a freedom-cancellation principle of Richard Gale which says that an agent is not free if all of her actions are intentionally brought about by another agent. Improved versions of (1) and (2) are (...) also considered. (shrink)

SpinozaÂ’s God is a being with infinite attributes, each of which expresses infinite essence. Does this mean that God has infinitely many attributes, each of which expresses infinite essence, or does God simply have attributes, each of which is infinite and expresses infinite essence? SpinozaÂ’s argumentation in Letter 9 and the Scholium to Prop. I.10 clearly indicates that it is not just each individual attribute that is infinite, but there are in some sense infinitely many of them. This would seem (...) to settle the issue, except that Spinoza never talks of more than two attributes, Extension..

The American Medical Association enacted its Code of Ethics in 1847, the first such national codification. In this volume, a distinguished group of experts from the fields of medicine, bioethics, and history of medicine reflect on the development of medical ethics in the United States, using historical analyses as a springboard for discussions of the problems of the present, including what the editors call "a sense of moral crisis precipitated by the shift from a system of fee-for-service medicine to a (...) system of fee-for-system medicine, better known as 'managed care.'" The authors begin with a look at how the medical profession began to consider ethical issues in the 1800s and subsequent developments in the 1900s. They then address the sociological, historical, ethical, and legal aspects of the practice of medicine. Later chapters discuss current and future challenges to medical ethics and professional values. Appendixes display various versions of the AMA's Code of Ethics as it has evolved over time. Contributors: George J. Annas, J.D., M.P.H., Arthur Isak Applbaum, Ph.D., Robert B.

“We are always already thrown into concrete factual circumstances, facing possibilities that we need to come to grips with. By choosing some we exclude others, thus making them no longer possible. What we are thrown into is the past and present, and the possibilities loom ahead of us, though we may try to turn our back on them. The future is the home of the possibilities while the present and past define the circumstances in which we make our choices, circumstances (...) we can no longer affect.” Or so we might say, and there is something right about this way of talking. Our basic conception of ourselves as agents is radically temporally asymmetric. And so we adopt asymmetric metaphors for time: we talk of time having a direction, as flowing from the future, through the present, to the past, closing possibilities that once were open; or perhaps we think of time as a measure of our own movement from the past to the future. Such metaphors are of very limited value. To think of time as having a direction spatializes time; to think of time as flowing or of ourselves as moving in time is to invite the question of how fast it is flowing or how fast we are moving (at one second per second, perhaps, one might quip, thereby inviting the question of why it cannot flow at two seconds per second instead).             Although the metaphors are flawed, we need to come to grips with an inextricable asymmetry between past and future in them. As agents, we deliberate about the future, while the past we can only bewail or rejoice over. We know the future not only through theoretical knowledge, but also through the intentional knowledge that the agent has of the effects she intends to produce. We think a life that started in years of sorrow but ended in great joy is preferable to one that started with a great joy and ended in years of sorrow..

          Kant believes that his moral theory prohibits lying under all possible circumstances, even those where there is a murderer at the door wondering if the innocent victim is in your house. After all, if everybody lied, even just to murderers at the door enquiring about the whereabouts of one’s actions, then the lying could not succeed since no murderer would believe what one says, and hence the action violates the first (...) form of the Categorical Imperative (CI). Likewise, the lie violates the second form of the CI by failing to respect the rationality of the murderer, since that rationality is exhibited through the self-legislation of ends whereas by lying we manipulate the murderer into actions directed at our own end, which end is opposed to the end that [1] the murderer has legislated for herself; thus, the liar fails to treat the murderer as an end.  I will not discuss the third form of the CI explicitly, as I take it to be essentially equivalent to the second form.           That lying even in such an extreme case is a violation of the CI is taken by many to be an argument against the CI. After all, the thought goes, in such cases one has a duty or at least permission to lie, and any moral theory that prohibits such a lie is immoral or at least overly strict. One line of defense a Kantian could take would be to argue that, pace Kant’s own beliefs about the matter, it does not violate the CI to lie in these circumstances. For instance, Korsgaard advocates a two-level theory on which the first form of the CI would apply under all circumstances and the second only when one is not defending oneself or another against evil, and argues that the first form of the CI is not violated in the case where the murderer makes a secret of her murderousness, since even were everybody to lie in those circumstances, the murderer would not expect the person at the door to lie as the murderer would expect her interlocutor not to know her murderous plans. I....

Consider the following three-step dialectics. (1) Even if God (consistently) commanded torture of the innocent, it would still be wrong. Therefore Divine Command Metaethics (DCM) is false. (2) No: for it is impossible for God to command torture of the innocent. (3) Even if it is impossible, there is a non-trivially true per impossibile counterfactual that even if God (consistently) commanded torture of the innocent, it would still be wrong, and this counterfactual is incompatible with DCM. I shall argue that (...) the last step of this dialectics is flawed because it would rule out every substantive metaethical theory. (shrink)
Consider the reasonable axioms of subjunctive conditionals (1) if p q 1 and p q 2 at some world, then p (q 1 & q 2) at that world, and (2) if p 1 q and p 2 q at some world, then (p 1 ∨ p 2) q at that world, where p q is the subjunctive conditional. I show that a Lewis-style semantics for subjunctive conditionals satisfies these axioms if and only if one makes a certain technical assumption (...) about the closeness relation, an assumption that is probably false. I will then show how Lewisian semantics can be modified so as to assure (1) and (2) even when the technical assumption fails, and in fact in one sense the semantics actually becomes simpler then.

The classical principle of double effect offers permissibility conditions for actions foreseen to lead to evil outcomes. I shall argue that certain kinds of closeness cases, as well as general heuristic considerations about the order of explanation, lead us to replace the intensional concept of intention with the extensional concept of accomplishment in double effect.
          Kant has claimed that lying is always wrong, even in response to a question from a murderer about the whereabouts of his intended victim. Christine Korsgaard has argued that although Kant’s second and third formulations in terms of respect for the humanity in persons and in terms of the Kingdom of Ends of the Categorical Imperative (CI) commit him to this claim, the first formulation in terms of universalizability does..
I defend a simple argument for why considerations of epistemic probability should lead us away from Open Future views according to which claims about the future are never true.
In the first chapter of Romans, Paul tells us that the power and deity of God are evident from what he has created. One reading of this is that there is an argument from the content of what has been created. Thus, the Book of Wisdom, which may well have been the source of Paul’s ideas here, says that “from the greatness and beauty of created things their original author, by analogy, is seen” (13:5, NAB). This is a kind of (...) teleological or design argument. But one might also argue instead from general features of the universe, such as the fact that there is a universe at all, or that there are contingent states of affairs, or that there is motion. Alternately, one might argue from something extremely specific, but where the details do not matter, such as the conjunction of all contingent facts. The general strategy of cosmological arguments is to take a grand feature of the world, and then argue, abstracting from much of its specific content, that the best or only possible explanation is a First Cause, an entity that stands at the head of a causal chain leading to the occurrence of the existential feature. Typically, the grand feature is something the opponent will not challenge. Instead, opponents tend to ask: 1. Does the grand feature actually have an explanation? 2. Can there be an explanation not involving a First Cause? 3. Need the First Cause be God? Recent discussion has particularly focused on the first two questions, and I wish to primarily focus on the first question myself in this talk. But first a few words about progress on the second and third question, in reverse order. (shrink)
          The cosmos is filled with evil that seemingly has no redeeming value. Granted, some evils do lead to greater goods, sometimes goods that could not exist without the evils. Thus, the exercise of courage is a good that requires either an actual evil to stand firm in the face of or the illusion of an evil—and an illusion is a kind of evil, too. But many evils appear to serve no (...) such purpose. Philosophers call an evil that a supremely good God would have insufficient reason to permit to exist a gratuitous evil. A particularly powerful form of the argument from evil against the existence of the God of Western monotheism is, thus, that there seem to be gratuitous evils, hence there probably are gratuitous evils, and so this God does not exist.           In his Sermon 125, St. Augustine says.

One of the problems that Bayesian regularity, the thesis that all contingent propositions should be given probabilities strictly between zero and one, faces is the possibility of random processes that randomly and uniformly choose a number between zero and one. According to classical probability theory, the probability that such a process picks a particular number in the range is zero, but of course any number in the range can indeed be picked. There is a solution to this particular problem on (...) the books: a measure that assigns the same infinitesimal probability to each number between zero and one. I will show that such a measure, while mathematically interesting, is pathological for use in confirmation theory, for the same reason that a measure that assigns an infinitesimal probability to each possible outcome in a countably infinite lottery is pathological. The pathology is that one can force someone to assign a probability within an infinitesimal of one to an unlikely event. (shrink)
I shall discuss the problem of the definition of lying and the formulation of the duty of truthtelling. I shall argue that the morality of assertion is a special case of the morality of endorsement, and that a criterion of adequacy for an account of lying is that it handles certain cases of dishonest endorsement as well. Standardviews of lying fail to do so. I shall offer an account of the duty of honest endorsement in terms of the intention to (...) avoid falsehood. But, in the end, we may simplyhave reason to go back to the naïve view that lying is saying falsehoods. (shrink)
