Primate vocal communication is very different from human language. Differences are most pronounced in call production. Differences in production have been overemphasized, however, and distracted attention from the information that primates acquire when they hear vocalizations. In perception and cognition, continuities with language are more apparent. We suggest that natural selection has favored nonhuman primates who, upon hearing vocalizations, form mental representations of other individuals, their relationships, and their motives. This social knowledge constitutes a discrete, combinatorial system that shares several (...) features with language. It is probably a general primate characteristic whose appearance pre-dates the evolution of spoken language in our hominid ancestors. The prior evolution of social cognition created individuals who were preadapted to develop language. Several features thought to be unique to language—like discrete combinatorics and the encoding of propositional information—were not introduced by language. They arose, instead, because understanding social life and predicting others’ behavior requires a particular style of thinking. (shrink)

Among monkeys and apes, both the recognition and classification of individuals and the recognition and classification of vocalizations constitute discrete combinatorial systems. One system maps onto the other, suggesting that during human evolution kinship classifications and language shared a common cognitive precursor.

To conclude that language evolved from vocalizations, through gestures, then back to vocalizations again, one must first reject the simpler hypothesis that language evolved from prelinguistic vocalizations. There is no reason to do so. Many studies – not cited by Arbib – document continuities in behavior, perception, cognition, and neurophysiology between human speech and primate vocal communication.

For more than sixty years, surgeons have used bioethical strategies to promote patient self‐determination, many of these now collectively described as “informed consent.” Yet the core framework—understanding, risks, benefits, and alternatives—fails to support patients in deliberation about treatment. We find that surgeons translate this framework into an overly complicated technical explanation of disease and treatment and an overly simplified narrative that surgery will “fix” the problem. They omit critical information about the goals and downsides of surgery and present untenable options (...) as a matter of patient choice. We propose a novel framework called “better conversations.” Herein, surgeons provide context about clinical norms, establish the goals of surgery, and comprehensively delineate the downsides of surgery to generate a deliberative space for patients to consider whether surgery is right for them. This paradigm shift meets the standards for informed consent, supports deliberation, and allows patients to anticipate and prepare for the experience of treatment. (shrink)

Since the Harvard Committees bold and highly successful attempt to redefine death in 1968 (Harvard Ad Hoc committee, 1968), multiple controversies have arisen. Stimulated by several factors, including the inherent conceptual weakness of the Harvard Committees proposal, accumulated clinical experience, and the incessant push to expand the pool of potential organ donors, the lively debate about the definition of death has, for the most part, been confined to a relatively small group of academics who have created a large body of (...) literature of which this issue of the Journal of Medicine and Philosophy is an example. Law and public policy, however, have remained essentially unaffected. This paper will briefly review the multiple controversies about defining death in an attempt to explain why they have and will remain unresolved in the academic community and have even less chance of being understood and resolved by politicians, legislators, and the general public. Considering this, we will end by suggesting the probable course of public policy and clinical practice in the decades ahead. (shrink)

One way of increasing the supply of vital organs without violating the dead donor rule is to declare death on cardiopulmonary criteria after withdrawing life support. The question then is how quickly death may be declared.

Xenotransplantation pits clinical research ethics against public health needs because recipients must undergo long-term, perhaps life-long, surveillance for infectious diseases. This surveillance requirement is effectively an abrogation of the right to withdraw from a clinical trial. Ulysses contracts, which are advance directives for future care, may be an ethical mechanism by which to balance public health needs against limitation of individual rights.

Determining whether a research risk meets or exceeds a regulatory standard of risk acceptability is difficult. Recently a framework called the systematic evaluation of research risks (SERR) has been proposed as a method of comparing research risks with predetermined standards of acceptability. SERR purports to offer a systematic and largely determinate (definite) way to compare risks and say whether a specific research risk falls below or above an acknowledged standard of acceptable risk. Here the authors review some philosophical problems with (...) this framework, which they take to be representative of determinate approaches to risk comparison, and conclude that it should not be used in a stand-alone or determinate fashion. Instead, the authors suggest that a deliberative approach may be a more viable candidate for future development. Such an approach could be informed by methods such as SERR without being rigidly bound to them. (shrink)

Two groups of plant viruses have DNA in their genomes. One group, the caulimoviruses, are non‐integrating retroviruses that package dsDNA in virions. The other group, the geminiviruses, package small circular ssDNA and include the only DNA viruses known with bipartite genomes. The regulation of transcription of these viruses is not well characterized, but recent work is beginning to yield interesting results. Regulatory sequences from these viruses function in cells of species that are not hosts of the virus and are finding (...) use in constitutive expression of chimeric genes in transformed plants. Development of vectors based on plant viruses requires further characterization at the molecular level of viral life cycles. (shrink)

Previous studies have documented the fallibility of attempts by surrogates and physicians to act in a substituted judgment capacity and predict end-of-life treatment decisions on behalf of patients. We previously reported that physicians misperceive their patients' preferences and substitute their own preferences for those of their patients with respect to four treatments: cardiopulmonary resuscitation in the event of cardiac arrest, ventilator for an indefinite period of time, medical nutrition and hydration for an indefinite period of time, and hospitalization in the (...) event of pneumonia.

Professionalism is demonstrated through attitudes and behaviors. Medical education is concerned with teaching and evaluating it among students. It is often bioethicists who teach professionalism to medical students. Most bioethics curricula use lectures and group discussions to introduce principles and theories, but there is variation in number of credit and contact hours, placement in the curriculum and alongside which courses bioethics is placed), the extent of individual mentoring, and the emphasis placed on any particular philosophical approach. Bioethics curricula also vary (...) in whether and how explicitly and extensively they address topics, including professionalism, cultural competence, medical humanities, spirituality, death and dying, and community service, and in the number and topics of vignettes, controversies, assignments, and course activities.

A review of *The Social Origins of Language* by Robert M. Seyfarth and Dorothy L. Cheney; edited and introduced by Michael L. Platt.

Surgery is an important part of health care worldwide. Without access to surgical treatments, morbidity and mortality increase. Access to surgical treatment is a significant problem in global public health because surgical services are not equally distributed in the world. There is a disproportionate scarcity of surgical access in low-income countries. There are many charitable organizations around the world that sponsor surgical missions to under served nations. One such organization is Operation Smile International, a group with which both authors have (...) volunteered. This paper will describe the purpose and processes involved in Operation Smile and identify some of the key ethical issues that arise in short term medical volunteer work highlighting the importance of sustainability.

In the Summa Theologiae ‘simplicity’ is treated as pre–eminent among the terms which may properly be used to describe the divine nature. The Question in which Thomas demonstrates that God must be ‘totally and in every way simple’ immediately follows the five proofs of God's existence, preceding the treatment of His other perfections, and being frequently used as the basis for proving them. Then in Question 13 ‘univocal predication' is held to be ‘impossible between God and creatures’ so that at (...) best ‘some things are said of God and creatures analogically’ because of the necessity of using ‘various and multiplied conceptions’ derived from our knowledge of created beings to refer to what in God is simple for ‘the perfections flowing from God to creatures… pre–exist in God unitedly and simply, whereas in creatures they are received divided and multiplied’ . In line with this, in the De Potentia Dei the treatment of analogical predication is integrated into that of ‘the Simplicity of the Divine Essence’ . Moreover, it lies at the root of Thomas's rejection of any possibility of a Trinitarian natural theology such as, for instance, St Anselm or Richard of St Victor had attempted to develop, on the grounds that ‘it is impossible to attain to the knowledge of the Trinity by natural reason’ since ‘we can know what belongs to the unity of the essence, but not what belongs to the distinction of the persons’ . Even modern minds sympathetic to Thomas have clearly found it difficult to understand his concern for the divine simplicity: in his Aquinas Lecture Plantinga speaks for many in stating that it is ‘a mysterious doctrine’ which is ‘exceedingly hard to grasp or construe’ and ‘it is difficult to see why anyone should be inclined to accept it’. Not surprisingly, therefore, some of the most widely read twentieth–century commentators on Aquinas have paid little attention to it. Increased interest has recently been shown in it, but a number of discussions pay insufficient attention to the historical context out of which Thomas's interest in the doctrine emerged, and consequently tend to misconstrue its nature.

One of our great behavioral scientists, the bestselling author of Behave, plumbs the depths of the science and philosophy of decision-making to mount a devastating case against free will, an argument with profound consequences Robert Sapolsky's Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but (...) that doesn't mean it doesn't exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do. Determined offers a marvelous synthesis of what we know about how consciousness works-the tight weave between reason and emotion and between stimulus and response in the moment and over a life. One by one, Sapolsky tackles all the major arguments for free will and takes them out, cutting a path through the thickets of chaos and complexity science and quantum physics, as well as touching ground on some of the wilder shores of philosophy. He shows us that the history of medicine is in no small part the history of learning that fewer and fewer things are somebody's "fault"; for example, for centuries we thought seizures were a sign of demonic possession. Yet, as he acknowledges, it's very hard, and at times impossible, to uncouple from our zeal to judge others and to judge ourselves. Sapolsky applies the new understanding of life beyond free will to some of our most essential questions around punishment, morality, and living well together. By the end, Sapolsky argues that while living our daily lives recognizing that we have no free will is going to be monumentally difficult, doing so is not going to result in anarchy, pointlessness, and existential malaise. Instead, it will make for a much more humane world. (shrink)

It is not too great an exaggeration to claim that On the Origin of Species was, along with Das Kapital, one of the two most significant works in the intellectual history of the nineteenth century. As George Henry Lewes wrote in 1868, ‘No work of our time has been so general in its influence’. However, the very generality of the influence of Darwin’s work provides the chief problem for the intellectual historian. Most books and articles on the subject assert the (...) influence but remain very imprecise about its nature. It is very difficult indeed to assess what it was about the Darwinian theory which was so influential and how its influence was felt. This problem in Victorian intellectual history intersects with a related one in the history of science. There has been a tendency on the part of historians of science to isolate Darwin in two related ways. The first is to single him out from the mainstream of nineteenth-century naturalism in Britain and allow ‘Darwinism’ to stand duty for the wider movement of which it was in fact but a part. The second is the tendency to single out his evolutionary theory and to demarcate it sharply from those of his predecessors and contemporaries. According to this interpretation Darwin stood alone as a real, empirical scientist and provided the first genuinely scientific hypothesis for the process by which evolution might have occurred. The theories of the other main evolutionists—Erasmus Darwin, Lamarck, Chambers, Spencer, and Wallace—were more or less besmirched by ideological, anthropomorphic, or other ‘non-scientific’ factors or by the uses to which they were put by their authors. Charles Darwin is thus made to stand out as a figure of comparatively unalloyed scientific status and is treated in relative isolation from the social and intellectual context in which he worked and into which his theory was received.

Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the (...) circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals? perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research. (shrink)

Modern historical criticism of the gospels and Christian origins began in the seventeenth century largely as an attempt to debunk the Christian religion as a pious fraud. The gospels were seen as bits of priestcraft and humbug of a piece with the apocryphal Donation of Constantine. In the few centuries since Reimarus and his critical kin, historical criticism has been embraced and assimilated by many Christian scholars who have seen in it the logical extension of the grammatico-historical method of the (...) Reformers. The new views of New Testament exegesis and of early Christian history are important and well known. Many New Testament scholars would now hold with Schweitzer and Bultmann that Jesus was a preacher of the imminent end of the world. He may have secretly considered himself to be the Messiah, or he may have simply sought to pave the way for another, the apocalyptic Son of Man. After his execution, his disciples' experiences of his resurrection forced on them a conclusion already implicit in his teachings and personal piety: that Jesus was indeed, or had become, the Messiah, and was in fact God's Son. They expected he would soon return as the Son of Man he had predicted. (shrink)
