Transhumanists advance a "posthuman" condition in which technological and genetic enhancements will transform humankind. They are joined in this goal by bioethicists arguing for genetic selection as a means of "enhancing evolution," improving if not also the species then at least the potential lives of future individuals. The argument of both, this paper argues, is a new riff on the old eugenics tune. As ever, it is done in the name of science and its presumed knowledge base. As ever, the (...) result is destructive rather than instructive, bad faith promoted as high ideal. The paper concludes with the argument that species advancement is possible but in a manner thoroughly distinct from that advanced by either of these groups. (shrink)

Many Greek moralists are eudaemonists; they assume that happiness is the ultimate end of rational human action. Socrates, Plato, Aristotle, and most of their successors treat this assumption as the basis of their ethical argument. But not all Greek moralists agree; and since the eudaemonist assumption may not seem as obviously correct to us as it seems to many Greek moralists, it is worth considering the views of those Greeks who dissent from it.

Much philosophical progress has been made in elucidating the idea of evolutionary contingency in a recent re-burgeoning of the debate. However, additional progress has been impaired on three fronts. The first relates to its characterisation: the under-specification of various contingency claims has made it difficult to conceptually pinpoint the scope to which ‘contingency’ allegedly extends, as well as which biological forms are in contention. That is—there appears to be no systematic means with which to fully specify contingency claims which has (...) led to a tendency for authors to talk past each other. Secondly, on the matter of evidence, recent research has focused on the evidential import of convergent evolution which is taken to disconfirm the evolutionary contingency thesis. However, there has been a neglect of convergent evolution’s converse: ‘evolutionary idiosyncrasies’ or the singular evolution of certain forms, which I argue is evidentially supportive of evolutionary contingency. Thirdly, evolutionary contingency has often been claimed to vary in degrees and that the debate, itself, is a matter of ‘relative significance’. However, there has been no formal method of evaluating the strength of contingency and its relative significance in a particular domain. In this paper, I address all three issues by proposing a systematic means of fully specifying contingency theses with the concept of the modal range. Secondly, I propose an account of evolutionary idiosyncrasies, investigate the explanations for their occurrences, and, subsequently, spell out their significance with respect to the evolutionary contingency thesis. Finally, having been equipped with the evidential counterpart to convergent evolution, I shall sketch a likelihood framework for evaluating, precisely on the basis of a sequence of opposing data, the strength and relative significance of evolutionary contingency in a particular domain. With this in hand, the relative observations of idiosyncrasies and convergences can be informative of the strength and relative significance of contingency in any particular domain. (shrink)

Why should Aristotle reject his own criteria for a science to admit this puzzling science of being? Or does he really reject them? Perhaps the science of being is not intended to be a universal science of the type rejected elsewhere. The Metaphysics and the Organon are not concerned with exactly the same questions; and verbal differences may not reflect real or important doctrinal conflicts.

Preventing exploitation in human subjects research requires a benchmark of fairness against which to judge the distribution of the benefits and burdens of a trial. This paper proposes the ideal market and its fair market price as a criterion of fairness. The ideal market approach is not new to discussions about exploitation, so this paper reviews Wertheimer's inchoate presentation of the ideal market as a principle of fairness, attempt of Emanuel and colleagues to apply the ideal market to human subjects (...) research, and Ballantyne's criticisms of both the ideal market and the resulting benchmark of fairness. It argues that the criticism of this particular benchmark is on point, but the rejection of the ideal market is mistaken. After presenting a complete account of the ideal market, this paper proposes a new method for applying the ideal market to human subjects research and illustrates the proposal by considering a sample case.

An interpretation is offered of Thrasymachus' account of the nature of justice and just action in book I of the 'Republic' which is internally consistent throughout on all important points. Just action is not defined in terms of its practical consequences, as many commentators assume, but rather in terms of its logical consequences 'vis-a-vis' just agents. When one man acts justly towards another, the performance of the just act renders the just agent vulnerable to unfair or unjust exploitation by those (...) with whom he deals. The "strong man", in Thrasymachus' sense, would thus never be a just man. It is argued that Socrates addresses himself to this position, but that, while the textual Thrasymachus is silenced, Socrates' best arguments are, in fact, inadequate to refute Thrasymachus.

Solon's fragments 9–11 are preserved in three late authors: frr. 9 and 11 by Diodoros Sikelos , 9.20.2, Plutarch , Solon 3.6 and 30.3 respectively, and Diogenes Laertios , 1.50 and 1.51 respectively; and fr. 10 by Diogenes Laertios alone, 1.49. They are all quoted in the context of Solon's reaction to Peisistratos. Stories on this theme were circulating by the time of the Aristotelian Athenaion Politeia , and Rhodes' scepticism about them is well founded. Its author did not garnish (...) his version of events with these poems, nor indeed with any Solonian utterance, and he explicitly states that myth-making on this subject had already resulted in two stories about Solon and Peisistratos which were chronologically impossible.

If there is such a thing as a genuine property appropriately called "intrinsic value" this property must be such that recognition that something does, or would, possess it, has a necessary tendency to motivate towards sustaining that thing in existence or producing it (if possible). There is just one thing which possesses that property and that is the property of being pleasurable (properly conceived) which, therefore, is the same as intrinsic value. (The same, mutatis mutandis, applies to intrinsic disvalue and (...) painfulness.) Why this seems not to be so is explained. (shrink)

Contingency-theorists have gestured to a series of phenomena such as random mutations or rare Armageddon-like events as that which accounts for evolutionary contingency. These phenomena constitute a class, which may be aptly called the ‘sources of contingency’. In this paper, I offer a probabilistic conception of what it is to be a source of contingency and then examine two major candidates: chance variation and genetic drift, both of which have historically been taken to be ‘chancy’ in a number of different (...) senses. However,contrathe gesturing of contingency-theorists, chance variation and genetic drift are not always strong sources of contingency, as they can be non-chancy in at least one sense that opposes evolutionary contingency. The probabilistic conception offered herein allows for sources of contingency to appropriately vary in strength. To this end, I import Shannon’sinformation entropyas a statistical measure for systematically assessing the strength of a source of contingency, which is part and parcel of identifying sources of contingency. In brief, the higher the entropy, the greater the strength. This is also empirically significant because molecular, mutational, and replicative studies often contain sufficient frequency or probability data to allow for entropies to be calculated. In this way, contingency-theorists can evaluate the strength of a source of contingency in real-world cases. Moreover, the probabilistic conception also makes conceptual room for the converse of sources of contingency: ‘sources of directionality’, which ought to be recognised, as they can interact with genuine sources of contingency in undermining evolutionary contingency.

Relations computed by finite-state transducers are applied to interpret temporal propositions in terms of strings representing finite contexts or situations. Carnap–Montague intensions mapping indices to extensions are reformulated as relations between strings that can serve as indices and extensions alike. Strings are related according to information content, temporal span and granularity, the bounds on which reflect the partiality of natural language statements. That partiality shapes not only strings-as-extensions (indicating what statements are about) but also strings-as-indices (underlying truth conditions).

The question whether an entity has rights is identified with that as to whether an intrinsic value resides in it which imposes obligations to foster it on those who can appreciate this value. There should be no difficulty in granting that animals have rights in this sense, but what of other natural objects and artifacts? It seems that various inanimate things, such as fine buildings and forests, often possess such intrinsic value, yet since they can only be fully actual in (...) an observing consciousness the most basic such right is that of being observed from time to time. That, at least, is true of them as phenomenal objects. There must, however, be a thing in itself behind the phenomenal object and sometimes this may possess an intrinsic value which gives rise to rights, not a matter of the need to be actualized in an observing consciousness, though it is extremely difficult to reach reliable conclusions here.

Can there be a moral philosophy which combines Christianity and consequentialism? John Stuart Mill himself claimed that these positions were, at the least, not mutually exclusive, and quite possibly even congenial to one another; and some recent work by Christian philosophers in America has resurrected this claim. But there is a simple argument to show that consequentialism and orthodox Christianity are not so much as jointly assertible.

IT HAS OFTEN BEEN SUPPOSED that Aristotle's account of thought and action imposes severe limits on the functions and scope of practical reason; and insofar as Thomas Aquinas accepts Aristotle's account, he seems to be forced into the same restrictive view of practical reason. Practical reason expresses itself primarily in deliberation ; and the virtue that uses practical reason correctly is the deliberative virtue of prudence. Aristotle believes that deliberation is confined to means to ends, while will is focused on (...) ends. Some ends that are assumed on some occasions may on other occasions also count as means to more ultimate ends; but it seems that the most ultimate ends must be taken for granted in any deliberation. Since every deliberation must take for granted some end to which the deliberation finds means, the conclusions of rational deliberation must ultimately be about means to ultimate ends that are not themselves subject to practical reason.

Here I first raise an argument purporting to show that Lewis’ Modal Realism ends up being entirely trivial. But although I reject this line, the argument reveals how difficult it is to interpret Lewis’ thesis that possibilia “exist.” Five natural interpretations are considered, yet upon reflection, none appear entirely adequate. On the three different “concretist” interpretations of ‘exist’, Modal Realism looks insufficient for genuine ontological commitment. Whereas, on the “multiverse” interpretation, Modal Realism acknowledges physical possibilities only--and worse, (assuming either axiom (...) S5 or axiom B) each possibilium ends up as a necessary physical existent. Finally, on the “broadly Actualist” of ‘exist’, Modal Realism is either inconsistent or it mistakenly identifies the unrestricted quantifier with the unrestricted Actualist quantifier. The upshot is that it remains obscure in what non-trivial sense Lewisian possibilia “exist.”. (shrink)

The emergence several years ago of SARS, with its high rate of infection and death among healthcare workers, resurrected a recurring ethical question: do health professionals have a duty to provide care to patients with deadly infectious diseases, even at some substantial risk to themselves and their families? The conventional answer, repeated on the heels of the SARS epidemic, is that they do. In this paper, I argue that the arguments in support of such a duty are wanting in significant (...) respects, and that the language of duty is simply not adequate to an understanding of all the moral dimensions of professional responses to the care of risky patients. Instead, we should speak the language of virtues and ideals if we want to do justice to the complexity of such harrowing circumstances. (shrink)

[Draft of October 2024] David Lewis acclimated us to talk of “nonactual concreta that exist,” regarding talking donkeys and the like. I shall argue that this was not for the best, and try to normalize a way of describing them as “actual concreta that do not exist.” The basis of this is a defense of the Meinongian thesis “there are objects of which it is true that there are no such objects,” re: fictitious and illusory objects. I first formulate the (...) problem of negative existentials in a novel way, and discuss why this new version is more forceful against anti-Meinongians. Additional data is also pressed against anti-Meinongians--e.g., the truth of ‘Pegasus is imaginary’, and a reading of ‘There actually are illusory objects’ where it comes out true. The Meinongian, in contrast, easily and uniformly explains the same data, by allowing the existence Pegasus, pink elephants, and the like. But contra Meinong, these cases suggest that the nonexistent objects are mind-dependent objects, and I clarify and defend this suggestion from several objections. The resulting Meinongianism is thus “conservative” in that it merely acknowledges the sense in which there are mind-dependent objects, imaginary and illusory objects being prime examples. Of special note, the “ideology” is conservative as well in that the typical Meinongian jargon of “nuclear” or “encoded” properties is paraphrased away. New suggestions about the ontology of abstracta, mere possibilia, and impossibilia are sketched in light of this. Comparisons are also made with Crane and McGinn, among others. (shrink)

We explicitly compute, following the method of Weyl, the commutator [Q, P] of the position operatorQ and the momentum operatorP of a particle when the dimension of the space on which they act is finite with a discrete spectrum; and we show that in the limit of a continuous spectrum with the dimension going to infinity this reduces to the usual relation of Heisenberg.

This paper is an attempt to elucidate the senses in which this place-name is used in Homer; to assign meanings to the Homeric terms Achaean, Iason and Pelasgic Arge, to ‘Argive’ as a synonym for Greek, and to establish the nature of the Argos over which Agamemnon ruled. I take the Homeric poems as the unity which they profess to be, and which they must be for historical enquiry. Whatever liberties Homer took with his materials it is plain he was (...) careful to respect events. The effort to distinguish between old and new in the Iliad and Odyssey has caused needless and fruitless encumbrance to the official historians, such as Busolt; the Unitarian position has given us the remarkable results of Professor Myres' . The consistency of Mr. Myres' account, and I venture to hope of mine, allows a fresh inference back to the homogeneity of the poems which are their source. (shrink)

One of four laws passed by Clodius early in 58 b.c. in some way modified the regulations governing obnuntiatio, the right possessed by magistrates and augurs to obstruct proceedings of the popular assemblies through announcement of unfavourable omens. The precise nature of the change is obscured by the fact that our main source, Cicero, describes it, as he does all of Clodius' legislation, in hyperbolic and polemical terms, alleging that it wholly abolished the right of obnuntiatio, a claim contradicted by (...) other evidence in his writings, which provide many examples of its continuing use. The later ancient sources repeat the substance of Cicero's main allegations and, accordingly, do little to help disentangle the facts from the hyperbole. Inadequate information about the earlier regulations relating to obnuntiatio, which were contained in two laws of the mid-second century, the Leges Aelia et Fufia, further hampers the search for the precise terms of Clodius' amendment. None of this, however, has discouraged speculation. The problem has exerted a peculiar fascination and has generated a succession of careful studies. Five main hypotheses have emerged: that the right of obnuntiatio was taken from curule magistrates; that it was taken from curule magistrates, but only in relation to legislative comitia; that it was taken from both curule magistrates and tribunes, but only in relation to legislative comitia; that it was abolished entirely, but soon restored by senatorial annulment of the reform; that it was left intact, but the assemblies were empowered to disallow it on any given occasion.

We discuss our surgical philosophy concerning the subtle interplay between the size of the surgical margin taken and the resultant morbidity from ablative oncological. procedures, which is ever more evident in the treatment of head and neck malignancy. The extent of tissue resection is determined by the "trade off" between cancer control and the perioperative, functional and aesthetic morbidity and mortality of the surgery. We also discuss our dilemmas concerning recent minimally invasive endoscopic microsurgical. techniques for the trans-oral laser removal. (...) or co-ablation of aero-digestive tract tumours, which result in a minimal. surgical margin of oncological clearance. By a process of inductive argument as to the nature of the surgical margin, we consider whether the risks of taking a lesser margin with adjuvant therapy is justified by the attendant gain in reduced surgical morbidity and the possible costs in tumour control.

The paper defends an Aristotelian notion of indeterminism, as rigorously formulated in the framework of branching space-times (BST) of Belnap (1992), against the model-theoretic characterization of indeterminism that Montague (1962) introduced into the philosophy of science. It delineates BST branching against the background provided by Earman's (2008) distinction between individual vs. ensemble branching. It describes a construction of physically-motivated BST models, in which histories are isomorphic to Minkowski spacetime. Finally it responds to criticism leveled against BST by addressing some semantical (...) questions, a topological issue, and the past/future asymmetry. (shrink)

I would like to raise a pressing issue relating to the World Health Organization which should concern the medical profession throughout the UK. The WHO Charter advocates the provision of health to all—as a human right. It is therefore to be regretted that these Charter obligations have not been exercised with respect to Taiwan whose 23 million citizens still cannot benefit from its protection. This democratic country which is a beacon of human rights in Asia, is still excluded from the (...) WHO. It is expected that in 2005 the island will …. (shrink)

Many people, failing to understand the theories of such ethical relativists as William Graham Sumner, Ruth Benedict and Edward Westermarck, have thought that various findings of the social sciences establish these theories. They regard the problem of ethical relativism, or the problem of determining whether or not any of these theories is sound, as a scientific problem. And they often think of ethical relativism as a scientific theory which explains these findings. In particular, it is widely thought that anthropologists have (...) amassed overwhelming evidence to prove that the moral beliefs of peoples of different cultures conflict or are diverse in such a way that this diversity of morals raises the problem of ethical relativism. And many have thought and continue to think that ethical relativism is demonstrated by this evidence and is a scientific hypothesis which accounts for the diversity of morals. The argument from the diversity of morals is the most popular argument for ethical relativism based on the data of the social sciences. (shrink)

Two levels can be distinguished in the structure of a language as a system of signs: the level of expression and the level of contents. Every sign of a language will thus be characterized by the unity of these two aspects. We can distinguish therein the signifying (.signans) and the signified (signatum), which correspond to the two levels of the language. Relations between the signifying and the signified in linguistic signs are determined by the relationship between their content and their (...) expression. Relations between signs at the level of contents and at the level of expression are the cause of the complex nature of the linguistic sign. (shrink)
