The Lévy-Solovay Theorem [8] limits the kind of large cardinal embeddings that can exist in a small forcing extension. Here I announce a generalization of this theorem to a broad new class of forcing notions. One consequence is that many of the forcing iterations most commonly found in the large cardinal literature create no new weakly compact cardinals, measurable cardinals, strong cardinals, Woodin cardinals, strongly compact cardinals, supercompact cardinals, almost huge cardinals, huge cardinals, and so on.

Gilbert Harman has argued that it does not make sense to ascribe character traits to people. The notion of morally virtuous character becomes particularly suspect. How plausible this is depends on how broad character traits would have to be. Views of character as entirely invariant behavioural tendencies offer a soft target. This paper explores a view that is a less easy target: character traits as specific to kinds of situation, and as involving probabilities or real possibilities. Such ascriptions are not (...) undermined by Harman's arguments, and it remains plausible that the agent's character often is indispensable in explanation of behaviour. Character is indispensable also as processes of control that impose reliability where it really matters. (shrink)

Infinite time Turing machines extend the operation of ordinary Turing machines into transfinite ordinal time. By doing so, they provide a natural model of infinitary computability, a theoretical setting for the analysis of the power and limitations of supertask algorithms.

Though most of analytic philosophy is based upon intuitions, some philosophers are beginning to question whether intuitions are an appropriate basis for philosophical theory. This paper responds to the arguments of some contemporary philosophers who hold that intuitions should not be treated as evidence for anything other than our contingent psychological constitution. It begins with a demonstration that skeptical arguments by Gilbert Harman and Alvin Goldman are variations on an argument with the potential to undermine the use of intuitions in (...) much philosophical inquiry. After a demonstration that Nicholas Sturgeon’s response to Harman’s argument is inadequate, it argues that all of the instances of the skeptical argument are unsuccessful because they are epistemically self-defeating.

_reduction in favour of his existentialist account of être au monde. I show that whilst Merleau-Ponty _ _rejected, what he saw as, the transcendental idealist context in which Husserl presents the _ _reduction, he nevertheless accepts the heart of it, the epoché, as a methodological principle. _ _Contrary to a number of Merleau-Ponty scholars, être au monde is perfectly compatible with the _ _epoché and Merleau-Ponty endorses both. I also argue that it is a mistake to think that Merleau-_ _Ponty’s (...) liberal use of the results of empirical psychology signify a rejection of the epoché. A proper _ _understanding of his views on the relation between phenomenology and psychology shows that, at _ _least in Merleau-Ponty’s eyes, the methods of phenomenology and the empirical sciences are _ _largely similar. I conclude that we have every reason to think that Merleau-Ponty accepted _ _Husserl’s demand that the phenomenologist place the world in brackets._. (shrink)

Biologists and philosophers have long recognized the importance of species, yet species concepts serve two masters, evolutionary theory on the one hand and taxonomy on the other. Much of present-day evolutionary and systematic biology has confounded these two roles primarily through use of the biological species concept. Theories require entities that are real, discrete, irreducible, and comparable. Within the neo-Darwinian synthesis, however, biological species have been treated as real or subjectively delimited entities, discrete or nondiscrete, and they are often capable (...) of being decomposed into other, smaller units. Because of this, biological species are generally not comparable across different groups of organisms, which implies that the ontological structure of evolutionary theory requires modification. Some biologists, including proponents of the biological species concept, have argued that no species concept is universally applicable across all organisms. Such a view means, however, that the history of life cannot be embraced by a common theory of ancestry and descent if that theory uses species as its entities.These ontological and biological difficulties can be alleviated if species are defined in terms of evolutionary units. The latter are irreducible clusters of reproductively cohesive organisms that are diagnosably distinct from other such clusters. Unlike biological species, which can include two or more evolutionary units, these phylogenetic species are discrete entities in space and time and capable of being compared from one group to the next.

The thesis that numbers are ratios of quantities has recently been advanced by a number of philosophers. While adequate as a definition of the natural numbers, it is not clear that this view suffices for our understanding of the reals. These require continuous quantity and relative to any such quantity an infinite number of additive relations exist. Hence, for any two magnitudes of a continuous quantity there exists no unique ratio. This problem is overcome by defining ratios, and hence real (...) numbers, as binary relations between infinite standard sequences. This definition leads smoothly into a new definition of measurement consonant with the traditional view of measurement as the discovery or estimation of numerical relations. The traditional view is further strengthened by allowing that the additive relations internal to a quantity are distinct from relations observed in the behaviour of objects manifesting quantities. In this way the traditional theory can accommodate the theory of conjoint measurement. This is worth doing because the traditional theory has one great strength lacked by its rivals: measurement statements and quantitative laws are able to be understood literally. 1 This paper was completed in 1990-1. while the author was a visiting scholar at the Irvine Research Unit in Mathematical Behavioral Sciences.

I have recently argued that origin essentialism regarding individual organisms entails that natural selection does not explain why individual organisms have the traits that they do. This paper defends this and related theses against Mohan Matthen's recent objections.

In "Frailty Triage: Is Rationing Intensive Medical Treatment on the Grounds of Frailty Ethical?," Wilkinson (2021) argues that the use of frailty scores in ICU triage does not necessarily involve discrimination on the basis of disability. In support of this argument, he claims, “it is not the disability per se that the score is measuring – rather it is the underlying physiological and physical vulnerability." While we appreciate the attention Wilkinson explicitly pays to disability in this piece, we find the (...) distinction between disability and underlying vulnerability untenable both theoretically and practically. In this peer commentary, we begin with a brief overview of research in philosophy of disability concerning the meaning of the concept itself. We argue that this research demonstrates that many forms of disability do not involve underlying vulnerabilities, and, furthermore, that Wilkinson equivocates between "disability" understood as a medical category vs. "disability" understood as a feature of lived experience. We reject Wilkinson’s distinction on these grounds and offer further considerations to avoid disability discrimination in emergency and crisis standards of care contexts. (shrink)

Many philosophers think there is a luck problem confronting libertarian models of free will. If free actions are undetermined, then it seems to be a matter of chance or luck that they occur—so the objection goes. Agent-causal libertarians have responded to this objection by asserting that free actions, in their essence, involve a direct causal relation between agents and the events they cause. So, free actions are not lucky after all. Not everyone, however, is convinced by this response. Al Mele (...) and Peter van Inwagen, for instance, argue that luckiness remains even if agent-causation exists. One way to answer their arguments, I suggest, is by appealing to considerations in metaphysical grounding and the associated idea of explanatory priority. Mele’s argument loses force if facts about which possible world is actual are partly grounded in facts about free choices themselves. And van Inwagen’s challenge can be met if facts about free actions are explanatorily prior to any objective probabilities associated with those actions. (shrink)

It has been argued - most prominently in Harry Frankfurt's recent work - that the normative authority of personal commitments derives not from their intrinsic worth but from the way in which one's will is invested in what one cares about. In this essay, I argue that even if this approach is construed broadly and supplemented in various ways, its intrasubjective character leaves it ill-prepared to explain the normative grip of commitments in cases of purported self-betrayal. As an alternative, I (...) sketch a view that focuses on intersubjective constraints of intelligibility built into social practices and on the pragmatics of how those norms are contested in an ongoing fashion.

Philosophers intent upon characterizing the difference between physics and biology often seize upon the purported fact that physical explanations conform more closely to the covering law model than biological explanations. Central to this purported difference is the role of laws of nature in the explanations of these two sciences. However, I argue that, although certain important differences between physics and biology can be highlighted by differences between physical and biological explanations, these differences are not differences in the degree to which (...) those explanations conform to the covering law model, which fits biology about as well as it does physics.

Under the enlightened rule of the Buyid dynasty the Islamic world witnessed an unequalled cultural renaissance. This book is an investigation into the nature of the environment in which the cultural transformation took place and into the cultural elite who were its bearers.

The clinical research enterprise is changing in fundamental ways. The bright line that separates research and clinical care is beginning to fade, as both “research” and “nonresearch” converge into and are embodied by the concept of the learning health care system. Here, data about care and operations are translated into practice improvement. VA has been a leader in this area, and based on its use of electronic health records and other inputs, has formed large databases and a data‐driven health care (...) system. These changes raise questions about the traditional approach to “research subject” protection. (shrink)

In this paper I defend three different points: first, that the concept of highest good is derived from an a priori but subjective argument, namely a maxim of pure practical reason; secondly, that the theory regarding the highest good has the validity of a practical regulative knowledge; and thirdly, that the practical regulative knowledge can be understood as the same “holding something to be true” as Kant attributes to hope and believe.

“Double-halfers” think that throughout the Sleeping Beauty Scenario, Beauty ought to maintain a credence of 1/2 in the proposition that the fair coin toss governing the experimental protocol comes up heads. Titelbaum (2012) introduces a novel variation on the standard scenario, one involving an additional coin toss, and claims that the double-halfer is committed to the absurd and embarrassing result that Beauty’s credence in an indexical proposition concerning the outcome of a future fair coin toss is not 1/2. I argue (...) that there is no reason to regard the credence required by the double-halfer as any less acceptable than the one deemed required by Titelbaum. (shrink)

For the “respectable” part of society there can be a presumption of virtuousness, rather like the presumption of innocence in the law. In both cases, the presumption can be defeated, as we learn more and get into specifics. We still might insist that to be genuinely virtuous is to be able to pass the more familiar sorts of tests of virtue, and to be reliably virtuous also in the ordinary business of life, especially in things that really matter. Something like (...) this is a necessary condition for virtue. Factors of motivation, especially those related to what a person's basic concerns are, can vary enormously. Imagine an extreme case. Someone might be inherently indifferent to what happens to other people, and have no sense of the inherent dignity or worthiness of moral principles, but also be totally convinced that God is watching his or her every move, and that the prospects of heaven or hell depend heavily on one's following accepted morality at every step.

My thesis is that advocacy in the classroom is rarely appropriate with regard to live moral, political, or social issues, and for that matter not always appropriate with regard to issues within a discipline. By advocacy I mean a teacher's presenting a view as her or his own in a way that might well elicit students' agreement. My argument against advocacy is supported by two sets of assumptions. One concerns the aims of higher education. The other concerns a distinction between (...) moral, political, and social issues that can be regarded as subjects of legitimate disagreement, on one hand, and on the other hand issues of these sorts that cannot be so regarded.

Cet article est consacré au thème de la déshumanisation chez Simone Weil. Elle cherche à expliquer la facilité avec laquelle les individus sont dépouillés de leur humanité et traités comme de simples choses. La phénoménologie éthique d’Emmanuel Levinas est sollicitée pour éclairer les analyses weiliennes. L’accent est particulièrement mis sur l’importance de l’attention en éthique et sur la complexe et ambiguë conception weilienne de l’individu, entité à la fois personnelle et impersonnelle.This article focuses on dehumanization in the writings of Simone (...) Weil. She tries to explain why people are easily stripped of their humanity and treated like material objects. In the article a comparison is drawn between her analysis of dehumanization and Emmanuel Levinas’ phenomenology of ethics. The emphasis is put on the importance of attention in ethics and on Weil’s complex and ambiguous conception of the individual as a personal and impersonal entity. (shrink)
