The lottery preparation, a new general kind of Laver preparation, works uniformly with supercompact cardinals, strongly compact cardinals, strong cardinals, measurable cardinals, or what have you. And like the Laver preparation, the lottery preparation makes these cardinals indestructible by various kinds of further forcing. A supercompact cardinal κ, for example, becomes fully indestructible by <κ-directed closed forcing; a strong cardinal κ becomes indestructible by κ-strategically closed forcing; and a strongly compact cardinal κ becomes indestructible by, among others, the forcing to (...) add a Cohen subset to κ, the forcing to shoot a club Cκ avoiding the measurable cardinals and the forcing to add various long Prikry sequences. The lottery preparation works best when performed after fast function forcing, which adds a new completely general kind of Laver function for any large cardinal, thereby freeing the Laver function concept from the supercompact cardinal context.

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)

“Intervention” is not synonymous with “care.” For an intervention to constitute care—which patients should have a right to access—it must be technically feasible and licit. Now these criteria do not prove sufficient; numerous archaic interventions remain feasible and legally permissible, yet are now bywords for spurious care. Therefore, we propound another necessary condition for an intervention to become care: the physician must rationally judge the intervention to be conducive to the patient’s good. Consequently, the right of access-to-care relies on physicians (...) being free to practice medicine in accord with their consciences, conscience being the rational faculty with which they judge the reasonableness of even mundane medical decisions. Since physicians operate as part of a community, it is further necessary to consider when central bodies may reasonably compel physicians to engage in interventions that the physician believes are not consistent with the patient’s good and/or are not congruent with the purposes of medicine.

Superstrong cardinals are never Laver indestructible. Similarly, almost huge cardinals, huge cardinals, superhuge cardinals, rank-into-rank cardinals, extendible cardinals, 1-extendible cardinals, 0-extendible cardinals, weakly superstrong cardinals, uplifting cardinals, pseudo-uplifting cardinals, superstrongly unfoldable cardinals, Σn-reflecting cardinals, Σn-correct cardinals and Σn-extendible cardinals are never Laver indestructible. In fact, all these large cardinal properties are superdestructible: if κ exhibits any of them, with corresponding target θ, then in any forcing extension arising from nontrivial strategically <κ-closed forcing Q∈Vθ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} (...) \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathbb{Q} \in V_\theta}$$\end{document}, the cardinal κ will exhibit none of the large cardinal properties with target θ or larger.

A pointwise definable model is one in which every object is \loos definable without parameters. In a model of set theory, this property strengthens $V=\HOD$, but is not first-order expressible. Nevertheless, if \ZFC\ is consistent, then there are continuum many pointwise definable models of \ZFC. If there is a transitive model of \ZFC, then there are continuum many pointwise definable transitive models of \ZFC. What is more, every countable model of \ZFC\ has a class forcing extension that is pointwise definable. (...) Indeed, for the main contribution of this article, every countable model of Gödel-Bernays set theory has a pointwise definable extension, in which every set and class is first-order definable without parameters.

This leading anthology contains legal cases and essays written by the best scholars in legal philosophy, representing all major points of view on central topics in philosophy of law. This classic text is distinguished by its clarity, readability, balance of topics, balance of substantive positions on controversial questions, topical relevance, imaginative use of cases and stories, and the inclusion of only lightly-edited or untouched classics. This revision is marked by inclusion of many articles relevant to womens issues and a greater (...) emphasis on concrete legal problems. (shrink)

The main theorem of this article is that every countable model of set theory 〈M, ∈M〉, including every well-founded model, is isomorphic to a submodel of its own constructible universe 〈LM, ∈M〉 by means of an embedding j : M → LM. It follows from the proof that the countable models of set theory are linearly pre-ordered by embeddability: if 〈M, ∈M〉 and 〈N, ∈N〉 are countable models of set theory, then either M is isomorphic to a submodel of N (...) or conversely. Indeed, these models are pre-well-ordered by embeddability in order-type exactly ω1+ 1. Specifically, the countable well-founded models are ordered under embeddability exactly in accordance with the heights of their ordinals; every shorter model embeds into every taller model; every model of set theory M is universal for all countable well-founded binary relations of rank at most OrdM; and every ill-founded model of set theory is universal for all countable acyclic binary relations. Finally, strengthening a classical theorem of Ressayre, the proof method shows that if M is any nonstandard model of PA, then every countable model of set theory — in particular, every model of ZFC plus large cardinals — is isomorphic to a submodel of the hereditarily finite sets 〈 HFM, ∈M〉 of M. Indeed, 〈 HFM, ∈M〉 is universal for all countable acyclic binary relations. (shrink)

We consider a set-theoretic version of mereology based on the inclusion relation ⊆ and analyze how well it might serve as a foundation of mathematics. After establishing the non-definability of ∈ from ⊆, we identify the natural axioms for ⊆-based mereology, which constitute a finitely axiomatizable, complete, decidable theory. Ultimately, for these reasons, we conclude that this form of set-theoretic mereology cannot by itself serve as a foundation of mathematics. Meanwhile, augmented forms of set-theoretic mereology, such as that obtained by (...) adding the singleton operator, are foundationally robust. (shrink)

In developing their policy on paediatric medical assistance in dying (MAID), DeMichelis, Shaul and Rapoport decide to treat euthanasia and physician-assisted suicide as ethically and practically equivalent to other end-of-life interventions, particularly palliative sedation and withdrawal of care (WOC). We highlight several flaws in the authors’ reasoning. Their argument depends on too cursory a dismissal of intention, which remains fundamental to medical ethics and law. Furthermore, they have not fairly presented the ethical analyses justifying other end-of-life decisions, analyses and decisions (...) that were generally accepted long before MAID was legal or considered ethical. Forgetting or misunderstanding the analyses would naturally lead one to think MAID and other end-of-life decisions are morally equivalent. Yet as we recall these well-developed analyses, it becomes clear that approving of some forms of sedation and WOC does not commit one to MAID. Paediatric patients and their families can rationally and coherently reject MAID while choosing palliative care and WOC. Finally, the authors do not substantiate their claim that MAID is like palliative care in that it alleviates suffering. It is thus unreasonable to use this supposition as a warrant for their proposed policy. (shrink)

We introduce the strongly uplifting cardinals, which are equivalently characterized, we prove, as the superstrongly unfoldable cardinals and also as the almost-hugely unfoldable cardinals, and we show that their existence is equiconsistent over ZFC with natural instances of the boldface resurrection axiom, such as the boldface resurrection axiom for proper forcing.

The use of other animals for human purposes is as contentious an issue as one is likely to find in ethics. And this is so not only because there are both passionate defenders and opponents of such use, but also because even among the latter there are adamant and diametric differences about the bases of their opposition. In both disputes, the approach taken tends to be that of applied ethics, by which a position on the issue is derived from a (...) fundamental moral commitment. This commitment in turn depends on normative ethics, which investigates the various moral theories for the best fit to our moral intuitions. Thus it is that the use of animals in biomedical research is typically defended by appeal to a utilitarian theory, which legitimates harm to some for the greater good of others; while the opposition condemns that use either by appeal to the same theory, but disagreeing about the actual efficacy of animal experimentation, or by appeal to an alternative theory, such as the right of all sentient beings not to be exploited. Unfortunately, the normative issue seems likely never to be resolved, hence leaving the applied issue in limbo. The present essay seeks to circumvent this impasse by dispensing altogether with any moral claim or argument, thereby cutting the Gordian knot of animal ethics with a meta-ethical sword. The alternative schema defended is simply to advance relevant considerations, whereupon “there is nothing left but to feel.” In a word, motivation replaces justification. (shrink)

Modal Platonism utilizes "weak" logical possibility, such that it is logically possible there are abstract entities, and logically possible there are none. Modal Platonism also utilizes a non-indexical actuality operator. Modal Platonism is the EASY WAY, neither reductionist nor eliminativist, but embracing the Platonistic language of abstract entities while eliminating ontological commitment to them. Statement of Modal Platonism. Any consistent statement B ontologically committed to abstract entities may be replaced by an empirically equivalent modalization, MOD(B), not so ontologically committed. This (...) equivalence is provable using Modal/Actuality Logic S5@. Let MAX be a strong set theory with individuals. Then the following Schematic Bombshell Result (SBR) can be shown: MAX logically yields [T is true if and only if MOD(T) is true], for scientific theories T. The proof utilizes Stephen Neale's clever model-theoretic interpretation of Quantified Lewis S5, which I extend to S5@. (shrink)

This article defends the ethical theory of william wollaston against the objections of hume and later writers who uncritically accepted hume's account of what wollaston said. I then argue that the true flaws in wollaston's view that all wrongdoing is false representing are that it cannot explain why some immoral acts are worse than others, And it presupposes antecedent moral principles of a different kind. I conclude that wollaston's theory, While failing as a general account of all immorality, Can nevertheless (...) be used to explain the difference between actions that are specifically unjust and actions that are immoral in other ways.

The infinite time Turing machine analogue of Post's problem, the question whether there are semi-decidable supertask degrees between 0 and the supertask jump 0∇, has in a sense both positive and negative solutions. Namely, in the context of the reals there are no degrees between 0 and 0∇, but in the context of sets of reals, there are; indeed, there are incomparable semi-decidable supertask degrees. Both arguments employ a kind of transfinite-injury construction which generalizes canonically to oracles.

Next SectionObjectives To evaluate the adequacy of paediatric informed consent and its augmentation by a supplemental computer-based module in paediatric endoscopy. Methods The Consent-20 instrument was developed and piloted on 47 subjects. Subsequently, parents of 101 children undergoing first-time, diagnostic upper endoscopy performed under moderate IV sedation were prospectively and consecutively, blinded, randomised and enrolled into two groups that received either standard form-based informed consent or standard form-based informed consent plus a commercial (Emmi Solutions, Inc, Chicago, Il), sixth grade level, (...) interactive learning module (electronic assisted consent). Anonymously and electronically, the subjects' anxiety (State Trait Anxiety Inventory), satisfaction (Modified Group Health Association of America), number of questions asked, and attainment of informed consent were assessed (Consent-20). Statistics were calculated using t test, paired t test, and Mann Whitney tests. Results The ability to achieve informed consent, as measured by the new instrument, was 10% in the control form-based consent group and 33% in the electronic assisted consent group (p<0.0001). Electronically assisting form-based informed consent did not alter secondary outcome measures of subject satisfaction, anxiety or number of questions asked in a paediatric endoscopy unit. Conclusions This study demonstrates the limitations of form-based informed consent methods for paediatric endoscopy. It also shows that even when necessary information was repeated electronically in a comprehensive and standardised video, informed consent as measured by our instrument was incompletely achieved. The supplemental information did, however, significantly improve understanding in a manner that did not negatively impact workflow, subject anxiety or subject satisfaction. Additional study of informed consent is required. Clinical trial registration number ClinicalTrials.gov Identifier NCT00899392. (shrink)

Rereading Renée C. Fox's “A Sociological Perspective on Organ Transplantation and Hemodialysis,” published in 1970, one is likely to be struck more by continuity than by change. The most pressing of the social, policy, and ethical concerns that Fox raised remain problematic fifty years later. We still struggle with scientific and clinical uncertainty, with the boundary between experimentation and therapy, and with the cost of organ replacement therapies and disparities in how they are allocated. We still have an imperfect understanding (...) of transplant immune responses. We still debate when a potential donor “actually” dies, and we still seem to think better empirical criteria could harmonize the diverse religious, cultural, and socioeconomic values of patients, providers, third‐party payers, and policy‐makers. Organ transplantation was for Fox both a particular case unfolding in time and an entryway for discussing the difficult moral questions presented by many new medical technologies in a context of high demand and limited resources.

Animal size is a relevant and unappreciated consideration in moral evaluations of killing animals for food, especially for utilitarians, who must weigh the gustatory satisfaction of eating meat-the quantity of which varies greatly throughout the animal kingdom-against animal suffering in utilitarian calculations. I argue that animal size can drastically alter not only the extent but even the valence of such calculations. Then I show how the business ethics literature on vegetarianism is deficient for not taking animal size into account. Last, (...) I argue that market conditions are also relevant in moral assessments of vegetarianism. (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.

This article examines the changing status of tropical biology by considering the origins and early development of the Barro Colorado Island Biological Laboratory. Today the laboratory is part of a large diversified tropical research center operated by the Smithsonian Institution. However, for most of its history the laboratory led a tenuous existence. Both the early problems and eventual success of the institution can only be explained by considering the interaction of various intellectual, institutional, and broader social factors.

Biocentrism, a prominent view in environmental ethics, is the notion that all and only individual biological organisms have moral status, which is to say that their good ought to be considered for its own sake by moral agents. I argue that biocentrism suffers two serious problems: the Origin Problem and the Normativity Problem. Biocentrism seeks to avoid the absurdity that artifacts have moral status on the basis that organisms have naturalistic origins whereas artifacts do not. The Origin Problem contends that, (...) contra biocentrism, an entity’s origin is not relevant to whether that entity has moral status. The Normativity Problem is that biocentrists are preoccupied with accounting for the goods or interests of nonsentient organisms yet fail to establish why interests so construed confer moral status; biocentrism fails to bridge the good-ought gap. It is shown how these problems emerge in three prominent book-length works representative of the biocentrists’ positions over three decades: Paul Taylor’s Respect for Nature, Gary Varner’s In Nature’s Interests?, and Nicholas Agar’s Life’s Intrinsic Value. At minimum, these criticisms suggest that biocentrism is crucially incomplete as a moral framework at present and, optimistically, where more work remains to be done. If biocentrism really is dead, then moral status should be restricted to a more plausible locus such as sentience or rationality, the value of organisms needs a different expression, and environmental ethics needs an axiological foundation different than bare life.

In apparent conflict with the popular conception of veterinarians as animals' best friends, the Veterinarian's Oath, as well as its clarifying Principles of Animal Welfare, imply that animal welfare is entirely derivative from human welfare. This article calls for an explicit alignment of the Oath and Principles with the priority of nonhuman animals.
