Ascidians have evolved alternate modes of development in which the conventional tadpole larva is remodeled or eliminated. Adultation, the precocious development of adult features in the larval head, is caused by superimposing the larval and adult differentiation programs. Caudalization, the addition of muscle cells to the larval tail, is caused by enhancing muscle induction or increasing the number of muscle cell divisions before terminal differentiation. Adultation and caudalization are correlated with increased egg size, suggesting dependence on maternal processes. Anural development, (...) the elimination of the larval stage, is caused by maternal and zygotic events resulting in abbreviation and deletion of larval developmental programs. An example of a maternal change in anural species is the modification of the egg cytoskeleton during oogenesis, whereas a zygotic change may involve altered cell interactions during embryogenesis. Interspecific hybridization experiments suggest that some aspects of anural development may be caused by loss‐of‐function mutations. The dissociation of developmental programs is a key process in changing the mode of development in ascidians. (shrink)

Recent studies have shown that some maternal mRNAs are localized in specific cytoplasmic regions of eggs and embryos and are rearranged in concert with the cytoplasmic movements that fix the embryonic axes. The localization and ooplasmic segregation of mRNA molecules may be mediated by their association with specific egg cytoskeletal domains.

Alan Chalmers uses Robert Boyle’s mechanical philosophy as an example of the irrelevance of ‘philosophy’ to ‘science’ and criticizes my 2006 book Atoms and alchemy for overemphasizing Boyle’s successes. The present paper responds as follows: first, it argues that Chalmers employs an overly simplistic methodology insensitive to the distinction between historical and philosophical claims; second, it shows that the central theses of Atoms and alchemy are untouched by Chalmers’s criticisms; and third, it uses Boyle’s analysis of subordinate causes and his (...) debate with Henry More in the 1670s to demonstrate the inadequacy of Chalmers’s construal of the mechanical philosophy.Keywords: Robert Boyle; Alan Chalmers; Geber; Paul of Taranto; Daniel Sennert; Alchemy; Chymistry; Mechanical philosophy; Reduction to the pristine state.

William R. Caspary makes the case for Dewey as a more discerning and challenging political theorist than this.

William Uttal is concerned that in an effort to prove itself a hard science, psychology may have thrown away one of its most important methodological tools—a critical analysis of the fundamental assumptions that underlie day-to-day empirical research. In this book Uttal addresses the question of localization: whether psychological processes can be defined and isolated in a way that permits them to be associated with particular brain regions. New, noninvasive imaging technologies allow us to observe the brain while it is (...) actively engaged in mental activities. Uttal cautions, however, that the excitement of these new research tools can lead to a neuroreductionist wild goose chase. With more and more cognitive neuroscientific data forthcoming, it becomes critical to question their limitations as well as their potential. Uttal reviews the history of localization theory, presents the difficulties of defining cognitive processes, and examines the conceptual and technical difficulties that should make us cautious about falling victim to what may be a "neo-phrenological" fad.

It no longer is true in a metaphorical sense only that a person can have a change of heart. We might grant this much — allow that a person may have one heart at one time and have another heart at still another time — and also resist the idea that a person can have a change of mind in anything other than a qualitative sense. In the discussion that follows, this standard view of the matter is called into question. (...) If the argument presented here is sound, it can happen both that one person has numerically different minds at different times and that different people have the same mind at different times. These possibilities, as I take them to be, call for reassessment of some well entrenched assumptions concerning personal identity and responsibility. In particular, they suggest that it may not be true that person A bears responsibility for making decisions person B previously made only on the condition that A is the same person as B. (shrink)

Lawsuits alleging illegal and unethical insurance sales practices have received widespread publicity in recent years. Although many observers have argued that one source of ethical conflicts for insurance agents is the industry's reliance on straight commission compensation, there remains a paucity of empirical data to support the claim. Therefore, we tested whether different forms of compensation influence insurance agent recommendations of products. We obtained survey responses from 336 insurance agents. Respondents were presented with a composite sketch of a hypothetical client. (...) Following this description, they were asked to identify which one of eight specified life insurance products they would recommend to the client. A between-groups design was employed to manipulate differences in compensation associated with the eight products. Results indicated that neither amount of coverage nor type of coverage (term life versus cash value) recommended was associated with compensation. However, an unanticipated finding was that amount of coverage recommended was significantly higher when the insured was male than when the insured was female. (shrink)

During the past few decades a growing interest in what is often called the ‘Kyoto School’ of philosophy has evidenced itself here and there in the West, especially in discussions of comparative religious thought and in the pages of journals which are sensitive, in the post-colonial world, to the value of giving attention to contemporary thought that originates outside the Anglo-American and continental contexts. What has made the so-called Kyoto School especially interesting is the fact that those thinkers identified with (...) it obviously possess a wide acquaintance with Western thought but also have a programme of clarifying points at which they, as Japanese philosophers, find Western philosophy either in sum or in its parts inadequate or objectionable. Moreover, inasmuch as the philosophers of the Kyoto School have deliberately reached back into the Mahayana Buddhist component in Japanese civilization in order to find terms, perspectives, and even foundations for their own analyses and constructions, Western students of comparative religion and comparative thought have in the study of this school a unique aperture for observing how a group of thinkers, while sharing modernity and its problems with us, reates both of these to a religious tradition which is in many ways strikingly different from that of the West.

Despite the fact that psychedelics were proscribed from medical research half a century ago, recent, early-phase trials on psychedelics have suggested that they bring novel benefits to patients in the treatment of several mental and substance use disorders. When beneficial, the psychedelic experience is characterized by features unlike those of other psychiatric and medical treatments. These include senses of losing self-importance, ineffable knowledge, feelings of unity and connection with others and encountering ‘deep’ reality or God. In addition to symptom relief, (...) psychedelic experiences often lead to significant changes in a patient’s personality and worldview. Focusing on the case of psilocybin, we argue that the peculiar features of psychedelics pose certain novel risks, which warrant an enhanced informed consent process–one that is more comprehensive than what may be typical for other psychiatric medications. We highlight key issues that should be focused on during the consent process and suggest discussion prompts for enhanced consent in psychedelic psychiatry. Finally, we respond to potential objections before concluding with a discussion of ethical considerations that will arise as psychedelics proceed from highly controlled research environments into mainstream clinical psychiatry.

Domain constraint, the requirement that analogues be selected from "the same category," inheres in the popular saying "you can't compare apples and oranges" and the textbook principle "the greater the number of shared properties, the stronger the argument from analogy." I identify roles of domains in biological, linguistic, and legal analogy, supporting the account of law with a computer word search of judicial decisions. I argue that the category treatments within these disciplines cannot be exported to general informal logic, where (...) the relevance of properties, not their number, must be the logically prior criterion for evaluating analogical arguments.

Professor R. J. Getty has drawn attention to a tenth- or early eleventh-century manuscript of Statius’ Thebaid, hitherto examined only in Book I, namely Turonensis. Dr. Klotz, in his Teubner edition of 1908, gave citations from Book I, and wrote, ‘dolendum est sane de hoc codice primum tantum librum innotuisse, sed cum Roffensis libri maxime affinis accuratiorem notitiam haberemus, collatione quamvis -aegre careri posse nobis visum est.’ I have collated both T and Roffensis in full, and find firstly that the (...) citations of r by Klotz are far from accurate, especially in the last six books, and secondly that while it is indeed true thatT and r are very closely related, T is a much better representative than r of their common source.

The list of Italian forces1 with which Virgil concluded Aeneid 7 was a piece of the ‘machinery’ of epic, that is to say an expected part of the content of an epic poem, established by Homer and expected of his successors; cf. Apollonius 1. 20–228, Silius 3. 222 f., Statius, Th. 4. 32 f., Milton, P.L. 1. 376 f. The straightforward enumeration of Homer was naturally appropriate in the Iliad both because oral technique sought this kind of directness and because (...) of the immediate relationship of the subject-matter to a heroic community. But Virgil was well aware that the Homeric manner would not fit satisfactorily into the sophisticated and elaborate structure of literary and contemplative epic. Two essential requirements had to be met in the transplanting of such ‘machinery’ into a new milieu. The first was one of function: the piece should blend with the whole intricate pattern of theme and tone which a poem like the Aeneid possesses. The second was one of structure: it must possess within itself artistic symmetries and designs of a carefully organized kind. (shrink)

Shortly after his arrival at Carthage, while he is waiting for Dido to meet him, Aeneas finds that the walls of her temple are adorned with pictures of the Trojan War. Sunt hie etiam sua praemia laudi, he cries to Achates, sunt lacrimae rerum et mentem mortalia tangunt. The description of the pictures which follows is a remarkable example of Virgil's ability to use a traditional device in such a way as to strengthen and illuminate the main themes of his (...) poem. It is my object here first to reinterpret one of the scenes which has been misunderstood, and then to discuss how Virgil has chosen and arranged his episodes so that the description of a picture gallery becomes a part of an epic poem.

In his note on Hesiod, WD 705 M. L. West tentatively suggests adeo for deo, saying rightly that ‘Charon is not a god in the literary tradition generally or in Virgil's scheme’. Palaeographically nothing could be more attractive than this emendation. But for all Virgil's fondness for adeo he does not use it in this intensifying sense with adjectives other than those indicating number, nor does he ever use it later than the second foot. The difficulty which West is combating (...) is a very real one, but it is not solved by the removal of deo. Virgil's dilemma was that the old ferryman must be as timeless as all the other members of Pluto's establishment, and to achieve this object of portraying an unchanging picture of the machinery of the underworld he has elevated Charon to the rank of dues. In Olympus the gods are frozen at the point suitable for the anthropomorphic vision of them: Cupid is always a boy, Apollo young and handsome, Neptune older and more austere. Similarly Charon is frozen just as he has reached vigorous old age. He may not be, indeed is not, a real god, but he is a necessary part of the world of the gods and so must share their agelessness.

The article investigates a system of polymorphically typed combinatory logic which is equivalent to Gödel’s T. A notion of (strong) reduction is defined over terms of this system and it is proved that the class of well-formed terms is closed under both bracket abstraction and reduction. The main new result is that the number of contractions needed to reduce a term to normal form is computed by an ε 0-recursive function. The ordinal assignments used to obtain this result are also (...) used to prove that the system under consideration is indeed equivalent to Gödel’s T. It is hoped that the methods used here can be extended so as to obtain similar results for stronger systems of polymorphically typed combinatory terms. An interesting corollary of such results is that they yield ordinally informative proofs of normalizability for sub-systems of second-order intuitionist logic, in natural deduction style. (shrink)

Why would a country strongly influenced by Buddhism's reverence for life allow legalized, widely used abortion? Equally puzzling to many Westerners is the Japanese practice of mizuko rites, in which the parents of aborted fetuses pray for the well-being of these rejected "lives." In this provocative investigation, William LaFleur examines abortion as a window on the culture and ethics of Japan. At the same time he contributes to the Western debate on abortion, exploring how the Japanese resolve their conflicting (...) emotions privately and avoid the pro-life/pro-choice politics that sharply divide Americans on the issue.

: A highly detailed application of Dewey's "dramatic rehearsal" to a particular ethical dilemma situation is developed here. This illustrates the role of moral imagination and creativity, and of self-discovery and self-transformation, within dramatic rehearsal. A primary concern is to show how decisions emerge through unification; what sorts of decisions emerge; how they can be evaluated; and whether the choices and evaluations accord with what is generally taken to be ethical/moral. Sartre's dilemma of a French student during World War II—who (...) is torn between staying with his mother who needed him and making his way to England to join the Free French Forces—provides the illustrative case. Using this case leads to a comparison of Dewey's and Sartre's approaches, and to a Deweyan reinterpretation and reconstruction of the process of decision in Sartre's early ethical theory. Criteria that Sartre, rightly, rejects as determinants of decision are shown to function in dramatic rehearsal as instruments for exploring the meanings of the dilemma. Sartre's analogy between making an ethical decision and creating a painting is explored in terms of Dewey's esthetic theory. This illuminates how dramatic rehearsal develops, and how it culminates in ethical decision. The idea that one makes oneself as one makes one's decision is shown to flow from the painting analogy, in both Sartre and Dewey. How this Deweyan account relates to Sartre's theory of radical choice is considered. Openings for the Deweyan perspective are sought in a brief exploration of Sartre's later ethical theories.

Skepticism about ethical expertise has grown common, raising concerns that bioethicists’ roles are inappropriate or depend on something other than expertise in ethics. While these roles may depend on skills other than those of expertise, overlooking the role of expertise in ethics distorts our conception of moral advising. This paper argues that motivations to reject ethical expertise often stem from concerns about elitism: either an intellectualist elitism, where some privileged elite have supposedly special access in virtue of expertise in moral (...) theory; or an authoritarian elitism, where our reliance on experts in ethics risks violation of autonomy and democracy. The paper sketches an anti-elitist conception of ethics expertise in bioethics as continuous with an anti-elitist conception of ethics expertise in common moral practice, undercutting the intellectualism, and then uses this anti-elitist conception to reject arguments that ethical expertise violates autonomy or democracy. An anti-elitist picture of ethical expertise both renders it consistent with our general moral practice and allows us to resist skeptical concerns. (shrink)

Debates about the ethics of health care and medical research in contemporary pluralistic democracies often arise partly from competing religious and secular values. Such disagreements raise challenges of balancing claims of religious liberty with claims to equal treatment in health care. This paper proposes several mid-level principles to help in framing sound policies for resolving such disputes. We develop and illustrate these principles, exploring their application to conscientious objection by religious providers and religious institutions, accommodation of religious priorities in biomedical (...) research, and treatment of patients’ religious views in doctor–patient encounters. Given that no sound set of guiding principles yields precise solutions for every policy dispute, we explore how morally sound democracies might deliberatively resolve such policy issues, following our proposed principles. Taken together and carefully interpreted, these principles may help in guiding difficult decision making in the indefinitely large realm where government, medical providers, and patients encounter problems concerning religion and medicine.
