The success of assisted reproductive technologies (ARTs) worldwide has led to an accumulation of frozen embryos that are surplus to the reproductive needs of those for whom they were created. In these situations, couples must decide whether to discard them or donate them for scientific research or for use by other infertile couples. While legislation and regulation may limit the decisions that couples make, their decisions are often shaped by their religious beliefs. Unfortunately, health professionals, scientists and policy-makers are often (...) unaware of the way in which faith traditions view ART and decisions concerning the ‘fate’ of surplus embryos. In this paper scholars representing six major religious traditions provide a commentary on a hypothetical case concerning the donation or destruction of excess ART embryos. These commentaries provide a rich account of religious perspectives on the status of the human embryo and an insight into the relevance of faith to health and policy decisions, particularly in reproductive medicine, ART and embryo research.

In the first chapter of The Contribution of Socratic Method and Plato’s Theory of Truth to Plato Scholarship, Rod Jenks argues that since Socrates and Plato take the Socratic elenchus to establish truths and the Socratic elenchus can only establish consistency, Socrates and Plato must be committed to a coherence theory of truth. Jenks denies any explicit recognition of such a commitment in Plato’s early dialogues. The claim is rather that “early Socratic practice as recorded by Plato makes sense only (...) against the backdrop of the assumption of a coherence theory of truth”. It is, according to Jenks, Plato’s solution to “the problem of the elenchus.” In the middle and later dialogues, Jenks argues, Plato exposes the philosophical foundations of this assumption and addresses various problems associated with it, only to return to the Socratic elenchus—now supported by a philosophically grounded CTT—in the Philebus.

The usual treatment of a dinner table utterance of ‘Can you pass the salt?’ is that it involves an indirect request to pass the salt as well as a direct question about the hearer’s ability to do so: an indirect speech act. These are held to involve two illocutionary forces and two illocutionary acts. Rod Bertolet has raised doubts about whether consideration of such examples warrants the postulation of indirect speech acts and illocutionary forces other than the literal ones. In (...) a recent article, Mary Kate McGowan, Shan Shan Tam, and Margaret Hall claim to show that these doubts are unfounded. The purpose of this paper is to show that they have not established this.

Generalized Darwinism (GD) claims to be a conceptual and theoretical framework for researching evolutionary change processes in organizations. This paper examines the claims of GD. It finds that in contrast to Darwin’s theory of evolution by natural selection proper, the GD framework is not an explanatory deductive argument form. What it is that GD actually generalizes and intends to explain thereby becomes somewhat moot. It is proposed that the so-called ‘generalization’ that the GD framework supplies might be best understood schematically. (...) Two general schemata that purport to distil commonalities between processes of organizational evolution and biological evolution are thereby identified. But in considering the applicability of the two schemata to organizational evolution, criticism reveals one to be problematic, whereas the other one, to which the GD programme collapses if the problematical schema is dispensed with, has been long associated with another so-called ‘evolutionary approach’ to the understanding of social change: Sir Karl Popper’s ‘evolutionary epistemology’. The paper concludes that if the research problem is to account for the evolutionary character of social and organizational change, then theorists need not commit to the GD framework. They may elect to use Popper’s evolutionary epistemology instead. (shrink)

This book offers a critical account of the fundamental elements of Leibniz's philosophy, as they manifest themselves in his metaphysics and philosophy of language. Emphasis is placed upon his hitherto neglected doctrine of nominalism, which states that only concrete individuals exist and that there are no such things as abstract entities – no numbers, geometrical figures or other mathematical objects, nor any abstractions such as space, time, heat, light, justice, goodness, or beauty. Using this doctrine as a basis, the book (...) considers the core of Leibniz's metaphysics and philosophy of language, including the well‐known principles of Contradiction, Sufficient Reason, Continuity and Individuation, and the concepts of Possible World, Individual Substance, Truth, and Necessity.

As bearers of the divine image, all of us are storytellers and artists. However, few people today believe in truth that is not empirically knowable or verifiable, the sort of truth often trafficked through direct forms of communication. Drawing on the works of Soren Kierkegaard, Benson P. Fraser challenges this penchant for direct forms of knowledge by introducing the indirect approach, which he argues conveys more than mere knowledge, but the capability to live out what one takes to be (...) true. Dr. Fraser suggests that stories aimed at the heart are powerful instruments for personal and social change because they are not focused directly on the individual listener; rather, they give the individual room or distance to reconsider old meanings or ways of understanding. Indirect communication fosters human transformation by awaking an individual to attend to images or words that carry deep symbolic force and that modify or replace one's present ways of knowing, and ultimately make one capable of embodying what he or she believes. Through an examination of the indirect approach in Kierkegaard, Jesus, C. S. Lewis, and Flannery O'Connor, Fraser makes a strong case for the recovery of indirect strategies for communicating truth in our time"--Back cover. (shrink)

While the early Platonic dialogues have often been explored and appreciated for their ethical content, this is the first book devoted solely to the epistemology of Plato's early dialogues. Author Hugh H. Benson argues that the characteristic features of these dialogues- -Socrates' method of questions and answers, his fascination with definition, his professions of ignorance, and his thesis that virtue is knowledge- -are decidedly epistemological. In this thoughtful study, Benson uncovers the model of knowledge that underlies these distinctively (...) Socratic views. What emerges is unfamiliar, yet closer to a contemporary conception of scientific understanding than ordinary knowledge. (shrink)

Non-human animals are as a matter of routine used as means to human ends. They are killed for food, employed for labour or sport, and experimented on in the pursuit of human health, knowledge, comfort and beauty. Lip-service is paid to the obligation to cause no unnecessary suffering, but human necessity is interpreted so generously that this is a negligible constraint. The dominant traditions of Western thought, religious and secular, have provided legitimation of the low or non-existent moral status of (...) beasts. The rival tradition, which includes the Neo-Platonists, Plutarch and Montaigne, is eccentric and archaic. But the teleologies and hierarchies of orthodoxy are equally incredible now and owe their greater respectability and influence to the inertia of custom. Disregard for beasts is supported partly by the vestigial and unowned belief that they are intended for our use, partly by a more recent piece of lore which is not only thought to be compatible with, but is sometimes held to be integral to, an enlightened scientific outlook, namely that beasts are mere complex stimulus—response mechanisms. The latter is a vexatious obstacle to progress but despite that the state of scientific and philosophical knowledge is now enormously more propitious for a re-appraisal of the moral status of beasts. Two moral philosophers, Peter Singer and Stephen Clark, have recently published books in which such a re-appraisal is attempted. Here I try to compare and assess some of the main features of their very different approaches. (shrink)

This paper contests Lynne Rudder Baker's claim to have shown that eliminative materialism is bound to fail on purely conceptual grounds. It is argued that Baker's position depends on knowing that certain developments in science cannot occur, and that we cannot know that this is so. Consequently, the sort of argument Baker provides is question-begging. For similar reasons, the confidence that the proponents of eliminative materialism have in it is misplaced.

A splitting of an r.e. set A is a pair A1, A2 of disjoint r.e. sets such that A1 A2 = A. Theorems about splittings have played an important role in recursion theory. One of the main reasons for this is that a splitting of A is a decomposition of A in both the lattice, , of recursively enumerable sets and in the uppersemilattice, R, of recursively enumerable degrees . Thus splitting theor ems have been used to obtain results about (...) the structure of , the structure of R, and the relationship between the two structures. Furthermore it is fair to say that questions about splittings have often generated important new technical developments in recursion theory. In this article we survey most of the results and techniques associated with splitting properties of r.e. sets in ordinary recursion theory. (shrink)

Hugh H. Benson explores Plato's answer to Clitophon's challenge, the question of how one can acquire the knowledge Socrates argues is essential to human flourishing-knowledge we all seem to lack. Plato suggests two methods by which this knowledge may be gained: the first is learning from those who already have the knowledge one seeks, and the second is discovering the knowledge one seeks on one's own. The book begins with a brief look at some of the Socratic dialogues where (...) Plato appears to recommend the former approach while simultaneously indicating various difficulties in pursuing it. The remainder of the book focuses on Plato's recommendation in some of his most important and central dialogues-the Meno, Phaedo, and Republic-for carrying out the second approach: de novo inquiry. The book turns first to the famous paradox concerning the possibility of such an inquiry and explores Plato's apparent solution. Having defended the possibility of de novo inquiry as a response to Clitophon's challenge, Plato explains the method or procedure by which such inquiry is to be carried out. The book defends the controversial thesis that the method of hypothesis, as described and practiced in the Meno, Phaedo, and Republic, is, when practiced correctly, Plato's recommended method of acquiring on one's own the essential knowledge we lack. The method of hypothesis when practiced correctly is, then, Platonic dialectic, and this is Plato's response to Clitophon's challenge. (shrink)

We investigate the index sets associated with the degree structures of computable sets under the parameterized reducibilities introduced by the authors. We solve a question of Peter Cholakand the first author by proving the fundamental index sets associated with a computable set A, {e : W e ≤ q u A} for q∈ {m, T} are Σ4 0 complete. We also show hat FPT(≤ q n ), that is {e : W e computable and ≡ q n ?}, is Σ4 (...) 0 complete. We also look at computable presentability of these classes. (shrink)

A general conceptualization of God’s omnipotence is that he possesses illimitable superior power over and above every other thing. Consequently, God is thought of being able to bring about “all” things. Such belief includes that as all-powerful, he does not need to be protected or defended by his creatures, insofar as he “cannot” be vulnerable to the threats or attacks of any creature, except possibly self-inflicted attacks, which would be selfcontradictory. Human power, on the other hand, assumes the belief that (...) even though God is absolutely omnipotent, believers in him have the duty to either carry out what they believe is his commandment or each one acts as he should act. This being so, the human claim to omnipotence absolutizes man/woman as being able, with impunity, in fact, with stupendous promise of reward, by acting as the “arm” or “brain” of God. The logical conclusion of such reasoning is to deny either claim of omnipotence by God or man. But how plausible would such a conclusion be to real-life situation? (shrink)

Philosophical arguments stemming from the public health ethics arena suggest that public health interventions ought to be subject to normative inquiry that considers relational values, including concepts such as solidarity, reciprocity and health equity. As yet, however, the extent to which ‘public’ values influence the ‘autonomous’ decisions of the public remains largely unexplored. Drawing on interviews with 50 men in Vancouver, Canada, this study employs a critical discourse analysis to examine participants’ decisions and motivations to voluntarily access HIV testing and/or (...) to accept a routine HIV test offer. Within a sub-set of interviews, a transactional discourse emerged in which the decision to test features an arrangement of ‘giving and receiving’. Discourses related to notions of solidarity emphasize considerations of justice and positions testing as a ‘public’ act. Lastly, ‘individualistic’ discourses focused on individual-level considerations, with less concern for the broader public ‘good’. These findings underscore how normative dimensions pertaining to men’s decisions to test are dialectically interrelated with the broader social and structural influences on individual and collective health-related behaviour, thereby suggesting a need to advance an explicit empirical-normative research agenda related to population and public health intervention research.

Contrary to conventional wisdom, the earlier Western tradition did not customarily deny souls per se to nonhuman animals; when it denied immortal souls to animals, it sometimes deemed that denial a reason for giving greater consideration to animals in their earthly existence. Nor has the Western tradition uniformly deemed animals intended for human use. Further, there was considerable opposition to the Cartesian view of animals as insentient machines, and—even among those who were convinced—it was not unknown for them to deem (...) it inappropriate to rely on that conviction in the treatment of animals. Moreover, Darwin's theory of evolution had neither a novel nor a positive impact on the way in which animals were to be regarded and treated. The study of the history of animal ethics needs to be rethought in a far more nuanced manner. (shrink)
