The last two decades have seen two significant trends emerging within the philosophy of science: the rapid development and focus on the philosophy of the specialised sciences, and a resurgence of Aristotelian metaphysics, much of which is concerned with the possibility of emergence, as well as the ontological status and indispensability of dispositions and powers in science. Despite these recent trends, few Aristotelian metaphysicians have engaged directly with the philosophy of the specialised sciences. Additionally, the relationship between fundamental Aristotelian concepts—such (...) as "hylomorphism", "substance", and "faculties"—and contemporary science has yet to receive a critical and systematic treatment. _Neo-Aristotelian Perspectives on Contemporary Science _aims to fill this gap in the literature by bringing together essays on the relationship between Aristotelianism and science that cut across interdisciplinary boundaries. The chapters in this volume are divided into two main sections covering the philosophy of physics and the philosophy of the life sciences. Featuring original contributions from distinguished and early-career scholars, this book will be of interest to specialists in analytical metaphysics and the philosophy of science. (shrink)

In this revised edition of his 1979 classic Political Theory and International Relations, Charles Beitz rejects two highly influential conceptions of international theory as empirically inaccurate and theoretically misleading. In one, international relations is a Hobbesian state of nature in which moral judgments are entirely inappropriate, and in the other, states are analogous to persons in domestic society in having rights of autonomy that insulate them from external moral assessment and political interference. Beitz postulates that a theory of international (...) politics should include a revised principle of state autonomy based on the justice of a state’s domestic institutions, and a principle of international distributive justice to establish a fair division of resources and wealth among persons situated in diverse national societies.

Professor Flathman's main aim in this interesting paper is to set forth what we might call the “moderation thesis.” It holds that there may be occasions when the best thing to do, all things considered, is to violate a right – at least if the violation takes the form of what Flathman calls “civil encroachment” or “civil non-enforcement.” Moreover, it would be desirable, in a society whose practices include rights, for this belief to be generally accepted, so that those who (...) engaged with good reason in “civil encroachment” would receive the sympathetic support of the community. Let me begin by trying to explain the source of the problem to which this thesis is a response. As Flathman notes, rights have a discretionary character: if I have a right to do or to have something, it is up to me whether to do it or to have it. Having a right, I am entitled to make a choice. Since we cannot say, in advance, what choice I will make, we cannot say, in advance, what will be the state of the world after I make it. But since it seems plain that some states of the world are more desirable than others, it will always be possible that the consequences of my choice will be worse, on the whole, than the consequences of some other choice that I might have made but did not. To moderate rights is apparently to act in ways that redress or compensate for the undesirable results of their exercise. (shrink)

James's Fairness in Trade seeks to offer an account of fair trade that is “internal” to an existing practice he describes as “mutual market reliance.” This paper distinguishes several senses of the distinction between “internal” and “external” that occur in the book and asks how, in its various senses, the distinction shapes and influences judgments about the fairness of the practice.

The collapse of historicism was not merely the demise of an academic tradition but signified a shift in the understanding of hermeneutics and metaphysics. Whereas earlier books have explored the rise and dominance of historicism within academic history, this is the first to trace its collapse and to show how it was shaped by larger philosophical and scientific concerns. Charles R. Bambach's lucid account of the demise of historicism within the context of German metaphysics provides a rich new perspective (...) on the development of the young Heidegger's concept of "historicity" and on the origins of postmodern thought. Bambach reconstructs the methodological debates arising from a pervasive sense of crisis among German philosophers in the late nineteenth century. He details the divergent attempts by the Neo-Kantians, Nietzsche, and Dilthey to overcome the limitations of historical relativism. Heidegger's view of "historicity," Bambach shows, radically transforms the problematic of historicism into a discourse concerning the crisis of philosophical modernity. (shrink)

Human rights have become one of the most important moral concepts in global political life over the last 60 years. Charles Beitz, one of the world's leading philosophers, offers a compelling new examination of the idea of a human right.

Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in recent years (...) by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

Global economic and political inequalities are in most respects greater today than they have been for decades. From one point of view inequality is a bad thing simply because it involves a deviation from equality, which is thought to have value for its own sake. But it is controversial whether this position can be defended, and if it can, whether the egalitarian ideal on which the defense may depend applies at the global level as in individual societies. Setting aside directly (...) egalitarian reasons for concern about global inequality, this paper explores several reasons for concern that derive from nonegalitarian values – primarily those associated with poverty and material deprivation, humiliation, the impact of inequality on the capacity for self‐control and self‐government, and the unfairness of political decision‐making procedures with large economic inequalities in the background.

_A concise history of “just price,” from Aristotle to the present day_ The question of what constitutes a fair price has been at the center of market interactions since the time of Aristotle. Should a seller sell to the highest bidder, or is there some other standard, such as a morally defined price, to be applied? Charles R. Geisst traces the ways that philosophers, religious leaders, and economists have sought to answer that question, from antiquity through the modern era. (...) Aristotle’s thinking on usury influenced the idea of pricing well into the Renaissance. In his view, money was barren and should not be used to beget more money. As trade became more extensive, the strictures placed on pricing by Aristotelian thinking began to fall away, replaced by Roman and common-law conceptions of value and interest. Geisst’s book follows the evolution of that thought—influenced along the way by figures such as Copernicus, Fibonacci, Adam Smith, Marx, Cassel, and Keynes—and charts parallel developments in European and Islamic notions of fair pricing. Today, pricing is seen as an economic inevitability, dictated by the laws of supply and demand. But this has not always been the case. As Geisst argues, the idea of a just price was once a moral concept, long before it was an economic one. (shrink)

Are conspiracy theorists epistemically vicious? That is the conventional wisdom. It has distinguished supporters, including Quassim Cassam, Cass Sunstein and Adrian Vermeule. For me, a trait is an epistemic virtue if leads to the discovery of salient truths and the avoidance of pernicious falsehoods, and an epistemic vice the contrary. As such epistemic virtues and vices are role‐relative, context‐relative and end‐relative. I argue that that it is not necessarily or even usually vicious to be a conspiracy theorist, even if we (...) restrict the conspiracies in question to conspiracies on the part of Western government agencies, the reason being that many such theories are now known to be true. Finally I contend that the policy suggested by some polemicists of systematic skepticism towards conspiracy theories would be intellectually suicidal and hence vicious. (shrink)

My first paper on the Is/Ought issue. The young Arthur Prior endorsed the Autonomy of Ethics, in the form of Hume’s No-Ought-From-Is (NOFI) but the later Prior developed a seemingly devastating counter-argument. I defend Prior's earlier logical thesis (albeit in a modified form) against his later self. However it is important to distinguish between three versions of the Autonomy of Ethics: Ontological, Semantic and Ontological. Ontological Autonomy is the thesis that moral judgments, to be true, must answer to a realm (...) of sui generis non-natural PROPERTIES. Semantic autonomy insists on a realm of sui generis non-natural PREDICATES which do not mean the same as any natural counterparts. Logical Autonomy maintains that moral conclusions cannot be derived from non-moral premises.-moral premises with the aid of logic alone. Logical Autonomy does not entail Semantic Autonomy and Semantic Autonomy does not entail Ontological Autonomy. But, given some plausible assumptions Ontological Autonomy entails Semantic Autonomy and given the conservativeness of logic – the idea that in a valid argument you don’t get out what you haven’t put in – Semantic Autonomy entails Logical Autonomy. So if Logical Autonomy is false – as Prior appears to prove – then Semantic and Ontological Autonomy would appear to be false too! I develop a version of Logical Autonomy (or NOFI) and vindicate it against Prior’s counterexamples, which are also counterexamples to the conservativeness of logic as traditionally conceived. The key concept here is an idea derived in part from Quine - that of INFERENCE-RELATIVE VACUITY. I prove that you cannot derive conclusions in which the moral terms appear non-vacuously from premises from which they are absent. But this is because you cannot derive conclusions in which ANY (non-logical) terms appear non-vacuously from premises from which they are absent Thus NOFI or Logical Autonomy comes out as an instance of the conservativeness of logic. This means that the reverse entailment that I have suggested turns out to be a mistake. The falsehood of Logical Autonomy would not entail either the falsehood Semantic Autonomy or the falsehood of Ontological Autonomy, since Semantic Autonomy only entails Logical Autonomy with the aid of the conservativeness of logic of which Logical Autonomy is simply an instance. Thus NOFI or Logical Autonomy is vindicated, but it turns out to be a less world-shattering thesis than some have supposed. It provides no support for either non-cognitivism or non-naturalism.

Philosophical attention to problems about global justice is flourishing in a way it has not in any time in memory. This paper considers some reasons for the rise of interest in the subject and reflects on some dilemmas about the meaning of the idea of the cosmopolitan in reasoning about social institutions, concentrating on the two principal dimensions of global justice, the economic and the political.

Contemporary ethical thought owes a great deal to David Hume whose work has inspired theories as diverse as non-cognitivism, error theory, quasi-realism, and instrumentalism about practical reason. This timely volume brings together an international range of distinguished scholars to discuss and dispute issues revolving around three closely related Humean themes which have recently come under close scrutiny. First is Hume's infamous claim that 'Reason is, and ought only to be, the slave of the passions'. Second, the Motivation Argument for the (...) view that 'The rules of morality...are not conclusions of our reason'. The third and final theme is that of virtue, re-examined here in the context of new interpretational debates concerning Hume's thought on moral motivation.

Beatrice Han argues that the theories of subjection (determinism: structure) and subjectivation (freedom: agency) are the “the blind spot of Foucault's work:” to the very end of his life, in being transcendental and historical theories, respectively, they were in irresolvable conflict. In part I, I have argued that Foucault encourages us to situate the theories of the subject in an un-thematized reach for a metaphysics of realism which, in effect, was to ground his uncertain complementary reach for a naturalist conduct (...) of research. In part II I also argue that it is this fundamental feature of Foucault's Foucault that drives his returns to Kant, the purpose of which is to resolve the conflicting theories of the subject, and thus to solve his Giddensian problem of structure and creativity. Locating the returns and their purpose in my context of Science for Humanism and the recovery of human agency, I ultimately argue that Foucault's two special returns to Kant in order to solve his structure/agency problem led to two unfortunate solutions. The resort to Baudelair's aesthetic subject is a failed solution in so far as it regresses to being a pre-noumenal conception of the subject. The subsequent mere reinstatement of Kant's subject as causally empowered, minus the noumenalism, is nothing more than a reclamation of Kant's conception. Only the reconstruction of Foucault's realism permits us to assert that he could have moved beyond the reclamation of human agency to its recovery. (shrink)

This new heuristic model of perceptual analysis raises interesting issues but in the end falls short. Its arguments are more in the Cartesian than Gestalt tradition. Much of the argument is based on setting up theoretical straw men and ignores well known perceptual and brain science. Arguments are reviewed in light of known physiology and traditional Gestalt theory.

In lieu of an abstract, here is a brief excerpt of the content:Update on Waiving Informed Consent in Emergency ResearchCharles R. McCarthyMadam: The closing statement of my article on Waiving Informed Consent in Emergency Research published in the June 1995 issue of the Kennedy Institute of Ethics Journal was: "No doubt we shall hear more of this issue."Indeed, we have heard much more on this issue. (1) In May 1995, after my article had already gone to press, the Food and (...) Drug Administration (FDA) and the National Institutes of Health (NIH) jointly published a report on the Public Forum on Informed Consent in Clinical Research Conducted in Emergency Circumstances. (2) On July 26, 1995, the Department of Health and Human Services (HHS) published in the Federal Register a Notice of Action Related to Emergency Research Activity (60 FR 38353-54). This action constituted a waiver of the requirement to obtain prior informed consent from subjects, as required by the Department's Regulations for the Protection of Human Subjects (45 CFR 46), for one specific NIH-funded project under strictly defined circumstances. (3) On September 21, 1995, FDA published a proposed rule to amend its current informed consent regulations (21 CFR 50) to permit harmonization of federal policies on emergency research and to reduce confusion as to when such research can proceed without obtaining prior informed consent from research subjects. The proposed regulation provides a narrow exception to the requirement for obtaining and documenting informed consent from each human research subject.The HHS waiver (a harbinger of a proposed amendment to its regulations) and the FDA proposed rule are intended to be harmonized so that an Institutional Review Board (IRB) in compliance with one set of regulations relative to the waiver of informed consent will be, ipso facto, in compliance with the other set of regulations.In brief: The FDA proposed amendments will allow an IRB to waive informed consent in emergency situations when:1. The human subjects are in a life threatening condition;2. Obtaining informed consent is not feasible because: (i) the subjects will not be able to provide consent because of their medical condition, (ii) the intervention must be administered before consent from legally authorized representatives is feasible, (iii) there is no reasonable way to identify prospectively the individuals likely to become eligible for the research because the emergence of the condition to be studied cannot be predicted reliably in particular individuals; [End Page 385]3. The opportunity to participate is in the interest of the subjects because: (i) a life threatening situation necessitates intervention, (ii) the risk of the intervention is reasonable in the light of what is known about the medical condition and the patient, the risks and benefits of current therapy, if any, and what is known about the risks and benefits of the proposed intervention or activity;4. The research could not practicably be carried out without the waiver;5. Additional protection of the rights and welfare of the subjects will be provided including, at least: (i) consultation (which may include consultation carried out by the IRB itself) with representatives of the communities from which the subjects will be drawn, (ii) public disclosure prior to commencement of the study sufficient to describe the study and its risks and benefits, (iii) public disclosure of sufficient information following completion of the study to apprise the community and researchers of the study and its results, and (iv) the establishment of an independent data and safety monitoring board;6. The IRB has reviewed and approved an informed consent document for use with subjects or legal representatives in situations in which obtaining such consent may be feasible for some subjects.The preamble to the proposed amendments to the regulations and the amendments themselves contain much more information than is presented here. Readers are therefore encouraged to study the proposals carefully. The public comment period ended November 6, and the FDA is expected to issue a final rule in 1996.Charles R.

In lieu of an abstract, here is a brief excerpt of the content:To Be or Not to Be:Waiving Informed Consent in Emergency ResearchCharles R. McCarthy (bio)The requirements for prior, legally authorized informed consent constitute a necessary condition for recruiting subjects into biomedical or behavioral research. However, informed consent requirements pose a serious problem for most research conducted in emergency care settings. For this reason, the Food and Drug Administration's (FDA) regulations governing investigational devices and the Department of Health and Human (...) Services' (HHS) regulations for the protection of human subjects allow narrow exceptions to the general requirements of informed consent. In a joint effort to clarify the applicability of the current FDA regulations and to better understand the intent of the HHS regulations as they apply to emergency research, the FDA and the National Institutes of Health (NIH) cosponsored a public forum on the ethical conduct of emergency research in January 1995.Although the forum was not designed as a consensus conference and participants vigorously disagreed on some of the details, a broad consensus emerged on several major points: (1) both HHS and FDA regulations should, in the immediate future, be interpreted to allow for randomized clinical trials in emergency situations so long as the subjects are carefully protected; and (2) consideration should be given to producing new, closely harmonized regulations from both agencies that will provide greater clarity concerning what kinds of emergency research may be allowed without obtaining prior informed consent.The FDA-NIH forum in January was occasioned primarily by controversy about the hypothermia research protocol described below, but it is obvious that many other kinds of emergency research also await the outcome of deliberations concerning waiver of informed consent in emergency situations. These include research into the care and treatment of: occlusive stroke; subarachnoid hemorrhage due to intracranial aneurysm; metabolic coma; status epilepticus; cardiac arrest; myocardial infarction; cardiac arrhythmia; hemorrhagic shock; pulmonary embolism; acute asthmatic attack; and poisoning. All of these conditions [End Page 155] are encountered in emergency settings where obtaining informed consent from the patient-subjects to participate in research is seldom possible, and obtaining consent from legally authorized representatives of the subjects is either not feasible, or, if obtained, is of doubtful validity.The Hypothermia Research Case and HHS RegulationsA $7.2 million grant for research on the use of hypothermia in the treatment of severe head trauma, the largest award ever made to the University of Texas Health Sciences Center at Houston, is in danger of expiring before the study is completed. The protocol, which involves the use of cooling blankets to induce hypothermia in patients suffering from severe head injuries, is designed to test the hypothesis that: "Early lowering of the body temperature of patients suffering from severe head trauma to approximately 91 degrees Fahrenheit will slow patients' metabolism and will/will not, as a consequence, reduce the rates of both morbidity and mortality in these patients." The protocol was approved by seven Institutional Review Boards (IRBs), each of which waived the requirement to obtain informed consent from research subjects in accordance with Sec. 46. 116(d) of the HHS Regulations for the Protection of Human Subjects.1However, NIH's Office for Protection from Research Risks (OPRR), which is responsible for assuring compliance with the HHS regulations, has taken a controversial regulatory position by requiring informed consent from a legally authorized representative of each subject to be entered in the hypothermia trial. Because the obtaining of surrogate consent has proved to be very difficult, OPRR's position has slowed the research to a point where it may have to be terminated.At issue in the controversy is a fundamental question of ethics and public policy. Is it ever permissible to involve incompetent subjects in research without either their consent, or the consent of their legally authorized representatives? Pertinent HHS regulations for the protection of human subjects seem to answer the question affirmatively by allowing local IRBs to waive some or all of the elements of informed consent under carefully limited circumstances (45 CFR 46 116(d)). Nevertheless, OPRR has signalled the research community that use of the informed consent waiver provision for the Houston hypothermia study is not permitted under the regulations. OPRR judged that the risks... (shrink)

Hebb's conception of instinctive behavior permits the conclusion that it is just not human nature to be instinctive: while the ant brain is built for instinctive behavior, the human brain is built for intelligent behavior. Since drives cannot be instincts, even when a human driver becomes driven, human motives are not instincts either. This understanding allows us to dismiss the determinism of the old instinctivism found in Freud's bio-psychological unconscious, and of the new instinctivism, exemplified by Wilson's sociobiology. The latter (...) entails an explanatory shift from instincts to genes, in which the deterministic character of instincts is carried over to genes. Since genes are not instincts this is a mistake.

l. There is an antinomy in Hare's thought between Ought-Implies-Can and No-Indicatives-from-Imperatives. It cannot be resolved by drawing a distinction between implication and entailment. 2. Luther resolved this antinomy in the l6th century, but to understand his solution, we need to understand his problem. He thought the necessity of Divine foreknowledge removed contingency from human acts, thus making it impossible for sinners to do otherwise than sin. 3. Erasmus objected (on behalf of Free Will) that this violates Ought-Implies-Can which he (...) supported with Hare-style ordinary language arguments. 4. Luther a) pointed out the antinomy and b) resolved it by undermining the prescriptivist arguments for Ought-Implies-Can. 5. We can reinforce Luther's argument with an example due to David Lewis. 6. Whatever its merits as a moral principle, Ought-Implies-Can is not a logical truth and should not be included in deontic logics. Most deontic logics, and maybe the discipline itself, should therefore be abandoned. 7. Could it be that Ought-Conversationally-Implies-Can? Yes - in some contexts. But a) even if these contexts are central to the evolution of Ought, the implication is not built into the semantics of the word; b) nor is the parallel implication built into the semantics of orders; and c) in some cases Ought conversationally implies Can, only because Ought-Implies-Can is a background moral belief. d) Points a) and b) suggest a criticism of prescriptivism - that Oughts do not entail imperatives but that the relation is one of conversational implicature. 8. If Ought-Implies-Can is treated as a moral principle, Erasmus' argument for Free Will can be revived (given his Christian assumptions). But it does not 'prove' Pelagianism as Luther supposed. A semi-Pelagian alternative is available. (shrink)

If literature isn’t everything, it’s not worth a single hour of some-one’s trouble.whenever we discuss literature, it is likely that at some point, we find the conversation turning to its sister discipline, philosophy. Both forms of expression offer interpretations of our experience delivered through the performance of language. Moreover, the relationship between philosophy and literature is reinforced by the obvious but seldom-stated fact that philosophers are not just thinkers; they are also writers. And our finest storytellers, the ones who transform (...) and deepen our understanding of the world, are not just writers; they, too, are engaged in the adventure of ideas, to borrow a phrase from Alfred North Whitehead....

In his celebrated 'Good and Evil' (l956) Professor Geach argues as against the non-naturalists that ‘good’ is attributive and that the predicative 'good', as used by Moore, is senseless.. 'Good' when properly used is attributive. 'There is no such thing as being just good or bad, [that is, no predicative 'good'] there is only being a good or bad so and so'. On the other hand, Geach insists, as against non-cognitivists, that good-judgments are entirely 'descriptive'. By a consideration of what (...) it is to be an A, we can determine what it is to be a good A, even where the ‘A’ in question is ‘human being’. These battles are fought on behalf of naturalism, indeed, of an up-to-date Aristotelianism. Geach plans to 'pass' from the 'purely descriptive' man to good/bad man, and from human act to good/bad human act. I argue: (l) That the predicative 'good' does have a genuine sense and that it is a mistake to suppose that ‘good’ is a purely attributive adjective. This does not entail that the predicative good (as used by Moore) denotes a non-natural property, but his mistake, if any is metaphysical or ontological not conceptual. (2) That the attributive 'good' cannot be used to generate a naturalistic ethic. It is difficult to extract a set of biologically based requirements out of human nature that are a) reasonably specific; b) rationally binding or at least highly persuasive; and c) morally credible. -/- On the way I protest against Geach’s tendency to try to win arguments by affecting not to understand things. -/- My views to some extent anticipate those of Kraut in *Against Absolute Goodness*.

We present a probabilistic extension to active path analyses of token causation (Halpern & Pearl 2001, forthcoming; Hitchcock 2001). The extension uses the generalized notion of intervention presented in (Korb et al. 2004): we allow an intervention to set any probability distribution over the intervention variables, not just a single value. The resulting account can handle a wide range of examples. We do not claim the account is complete --- only that it fills an obvious gap in previous active-path approaches. (...) It still succumbs to recent counterexamples by Hiddleston (2005), because it does not explicitly consider causal processes. We claim three benefits: a detailed comparison of three active-path approaches, a probabilistic extension for each, and an algorithmic formulation. (shrink)

Classifying species as ‘native’ or ‘alien’ carries prescriptive force in the valuation and management of ‘nature’. But the classification itself and its application are contested, raising philosophical and geographical questions about place, space, rights, identity and belonging. This paper discusses leading critiques of the native/alien paradigm, including its conceptual fluidity, dichotomous rigidity and ethical difficulties, as well as the incendiary charge of xenophobia. It argues that valorizing ‘native nature’ as inherently the ‘best nature’ is not only obsolete but impracticable in (...) the Anthropocene, and that the preeminence of biogeographic origins should be replaced with a pragmatic focus on species’ behavior.
