This book examines Platos account in the Timaeus of a third kind and its cosmic members, a material principle and place.

Plato’s chief argument against rhetoric is epistemological. Plato claims that rhetoric accomplishes what it does on the basis of experience,not knowledge. In this article I examine Plato’s criticisms of rhetoric in the Gorgias and the Phaedrus. I argue that Plato is right to identify rhetoric’s empirical basis, but that having this epistemic basis does not constitute an argument against rhetoric. On the contrary, Plato’s criticism of rhetoric serves to give us an epistemological explanation of rhetoric’s success.

This is a wonderful book. It is, in my opinion, the best book on Aristotle’s treatment of the physical world to appear in recent years. Still, this book is not one that can be read through on a Sunday afternoon. It resembles a text of Aristotle in the compactness of argument, though not, I am happy to report, in clarity. Like a guide raised in the wild, Lang leads us through a large sector of the forest of arguments in the (...) Physics and De Caelo. This analogy brings me to the following point: Lang’s perspective on Aristotle is extraordinary. Lang is the author of another excellent book, Aristotle’s Physics and Its Medieval Varieties. Discussions of Aristotle’s philosophy of nature through the lens of medieval philosophy and science are not uncommon. These discussions, however, face the peril of attributing, in one way or another, viewpoints to Aristotle that are actually those of his medieval successors. For this reason most work on Aristotle is now done without reference to medieval thought. Perhaps this is as it should be. But one of the great difficulties in understanding Aristotle’s conception of the world is how we are to interpret what he says. Our perspective on the world is largely formed on the basis of early modern rejections of medieval Aristotelian views. That is to say that built into our perspective is a negative response not to Aristotle directly but to medieval interpretation of Aristotle. This fact makes it extremely difficult for us to see Aristotle clearly. Here lies the advantage of knowing the “medieval varieties” of Aristotle’s natural philosophy when we try to make sense of Aristotle. Knowing this helps us distinguish more clearly between our own perspective and its roots and Aristotle’s. Aristotle’s perspective is in fact fundamentally different from ours. For example, Lang points out that to insert the notion of “speed” into Aristotle’s discussion of motion is “seriously misleading” because speed is conceptually distinguishable from moving bodies and is so treated, whereas motion, for Aristotle, is always the actualization of a capacity intrinsic to a moved body; therefore motion can neither be quantified nor abstracted from what is moved.

It is difficult to write clearly about any aspect of Plotinus’ thought. There are many reasons for this. One reason is that he is a very systematic thinker. So, for example, to treat his aesthetics one must also discuss his metaphysics, psychology, and his ethics. Anther reason is his well-known subtlety and obscurity of expression. Kuisma’s book on Plotinus’ aesthetics, however, shows that it is possible to write clearly, accurately, and succinctly about Plotinus. This book is a pleasure to read. (...) Kuisma argues against a modern, widely held interpretation of Plotinus’s aesthetics which claims that “Plotinus, in contrast to Plato, accepted the possibility of the artistic imitation of intelligible Forms,” thus giving “a new direction to Platonic art theory”. His thesis is, instead, that “the objects of artistic imitation are limited to the sphere of perceptions,” although this limitation can be overcome to some extent by “the use of symbols and symbolic conventions”, inasmuch as symbolic representations do not convey on the basis of sameness of form. He calls the common view “strong mimesis,” and his own view, “weak mimesis”. Clearly, Kuisma’s view shows Plotinus to be a traditional Platonist. Indeed, it would be odd if Plotinus, of all people, should discount Plato’s doubts about the ability of sensibles to represent eternal form. (shrink)

This is a collection of essays, many of which were given originally as papers at a conference on Ancient Method held at Amherst College in 1994. Few directly address the subject of method in ancient philosophy. Readers whose primary interest is this subject and have high hopes for this new volume from Oxford University Press will be somewhat disappointed. Yet those of us whose interests in ancient philosophy are broader will find not a few excellent essays on important questions by (...) some of the leaders in the field. (shrink)

Soil is fragile and nonrenewable but the most basic of natural resources. It has a capacity to tolerate continuous use but only with proper management. Improper soil management and indiscriminate use of chemicals have contributed to some severe global environmental issues, e.g., volatilization losses and contamination of natural waters by sediments and agricultural fertilizers and pesticides. The increasing substitution of energy for labor and other cultural inputs in agriculture is another issue. Fertilizers and chemicals account for about 25% of the (...) production energy investment in agriculture. An additional 60% is accounted for by machinery, gasoline, electricity, and power-related inputs. Fertilizer additions to cropland are not utilized fully and significant amounts, depending on conditions, are either lost in surface runoff or leached into the ground water. The annual discharge of dissolved solids from agricultural lands to the waterways in the USA is substantial. The increasing use of herbicides in agriculture is a threat to the quality of surface and ground water, although this threat is dependent upon both the chemistry of the compound and the ecosystem in which it is used. Especially within the Third World, development of an environmental ethic and environmental laws have not kept pace with the increase in pesticide use. Above all is the severe and global problem of soil degradation currently occurring at the rate of five to seven million hectares per year. The policy and moral aspects of these issues are discussed.

We examine the influences of social capital, source credibility, and fairness perceptions on the judgments of experienced compensation committee members who are considering a proposal to reduce management’s performance targets in the middle of a compensation cycle due to difficult circumstances. Eighty-nine U.S. public company CC members participated in a 2 × 2 experiment with social capital and source credibility each manipulated as low or high, and outcome fairness to management, process fairness to shareholders, and outcome fairness to shareholders included (...) as measured variables. While social capital and source credibility are not significant, we find that outcome fairness to the CEO and outcome fairness to shareholders are significantly related to CC members’ support for reducing performance targets during a compensation cycle. In addition, we find that more experienced CC members are less supportive of changing the performance targets. The significant interactions include one between outcome fairness to shareholders and process fairness to shareholders, which suggests that CC member support for the proposal relies on both process and outcome fairness being present. Finally, the participants’ qualitative responses reflect arguments both for and against adjusting performance targets. Overall, the results highlight the important roles of fairness and director experience in boardroom decisions and provide important insights into factors affecting CC judgments. (shrink)

The literature on self-driving cars and ethics continues to grow. Yet much of it focuses on ethical complexities emerging from an individual vehicle. That is an important but insufficient step towards determining how the technology will impact human lives and society more generally. What must complement ongoing discussions is a broader, system level of analysis that engages with the interactions and effects that these cars will have on one another and on the socio-technical systems in which they are embedded. To (...) bring the conversation of self-driving cars to the system level, we make use of two traffic scenarios which highlight some of the complexities that designers, policymakers, and others should consider related to the technology. We then describe three approaches that could be used to address such complexities and their associated shortcomings. We conclude by bringing attention to the “Moral Responsibility for Computing Artifacts: The Rules”, a framework that can provide insight into how to approach ethical issues related to self-driving cars.

Conservatives and liberals disagree sharply on matters of morality and public policy. We propose a novel account of the psychological basis of these differences. Specifically, we find that conservatives tend to emphasize the intrinsic value of actions during moral judgment, in part by mentally simulating themselves performing those actions, while liberals instead emphasize the value of the expected outcomes of the action. We then demonstrate that a structural emphasis on actions is linked to the condemnation of victimless crimes, a distinctive (...) feature of conservative morality. Next, we find that the conservative and liberal structural approaches to moral judgment are associated with their corresponding patterns of reliance on distinct moral foundations. In addition, the structural approach uniquely predicts that conservatives will be more opposed to harm in circumstances like the well-known trolley problem, a result which we replicate. Finally, we show that the structural approaches of conservatives and liberals are partly linked to underlying cognitive styles. Collectively, these findings forge a link between two important yet previously independent lines of research in political psychology: cognitive style and moral foundations theory. (shrink)

Ethical guidelines for conducting clinical trials have historically been based on a perceived therapeutic obligation to treat and benefit the patient-participants. The origins of this ethical framework can be traced to the Hippocratic oath originally written to guide doctors in caring for their patients, where the overriding moral obligation of doctors is strictly to do what is best for the individual patient, irrespective of other social considerations. In contrast, although medicine focuses on the health of the person, public health is (...) concerned with the health of the entire population, and thus, public health ethics is founded on the societal responsibility to protect and promote the health of the population as a whole. From a public health perspective, research ethics should be guided by giving due consideration to the risks and benefits to society in addition to the individual research participants. On the basis of a duty to protect the population as a whole, a fiduciary obligation to realise the social value of the research and the moral responsibility to distribute the benefits and burdens of research fairly across society, how a public health perspective on research ethics results in fundamental re-assessments of the proper course of action for two salient topical issues in research ethics is shown: stopping trials early for reasons of efficacy and the conduct of research on less expensive yet less effective interventions.

As a natural example of a 1-random real, Chaitin proposed the halting probability Ω of a universal prefix-free machine. We can relativize this example by considering a universal prefix-free oracle machine U. Let [Formula: see text] be the halting probability of UA; this gives a natural uniform way of producing an A-random real for every A ∈ 2ω. It is this operator which is our primary object of study. We can draw an analogy between the jump operator from computability theory (...) and this Omega operator. But unlike the jump, which is invariant under the choice of an effective enumeration of the partial computable functions, [Formula: see text] can be vastly different for different choices of U. Even for a fixed U, there are oracles A =* B such that [Formula: see text] and [Formula: see text] are 1-random relative to each other. We prove this and many other interesting properties of Omega operators. We investigate these operators from the perspective of analysis, computability theory, and of course, algorithmic randomness.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Age of Grace: “Charis” in Early Greek PoetryDana R. SmithThe Age of Grace: “Charis” in Early Greek Poetry, by Bonnie MacLachlan; xxi & 192 pp. Princeton: Princeton University Press, 1992, $29.95.Bonnie MacLachlan has two concerns in this book. First, she sees early charis, conventionally and inadequately translated as “grace,” as the result of feeling, concrete action, and sometimes concrete objects, fused in such a way that early (...) Greeks did not clearly distinguish these as separate aspects. Second, she focuses on the experience of beauty or pleasure as a crucial part of reciprocity in charis, and argues that many of the now-fashionable models from the social sciences, such as those dealing with reciprocal exchange of goods and favors, are insufficient to account for this particular dynamic of allurement. What later ages sensed, and what we sense, as two or more different kinds of charis “may not have been sensed as such by the archaic Greek mind.” Rather, the early Greeks possessed an integrated sense of these fragments as part of a single experience. “A charis-event, provoked by moral or aesthetic beauty, was disarming; it broke down the barriers of the self, and it demanded that the beneficiary reach out to another.” This study combines extremely able discussions of different sides of this crucial concept with a large vision of their integration into a coherent whole: “[Charis] was the moral glue of their society, linking such other central moral ideas as timê [“honor,” “prerogative,” “price”], dikê [“due portion,” “justice”], themis [“unwritten law”], xenia [“requital of gifts and hospitality”], and aidôs [“reverence,” “awe”].”How well does MacLachlan demonstrate this twofold idea? She deserves high praise for setting forth the essential passages of her authors clearly and succinctly, for giving numerous insights into them, for adducing much pertinent scholarship, and certainly for furthering the development of her important thesis. Her discussion of the earliest conception of charis (chap. 2, “The Charis of Achilles”), focused mainly on Homer, with material from the Homeric Hymns and Hesiod, gives a sensitive and persuasive account of relations among charis, timê, and dikê. She makes excellent points about specific perceptions of beauty, especially visual, although one comes away a bit uncertain as to how these aspects all cohere, and also as to whether there are differences in charis between the Iliad and the Odyssey. Her discussion of the cult dimensions of charis (chap. 3, “The Charites”), while fascinating in itself, contains little direction for using this information so as to understand the thesis. She gives careful readings of her examples of erotic and social charis (chaps. 4 and 5, “Erotic Charis” and “Social Charis”), clearly identifying types that contrast with the earlier prototypical experience, although sometimes her criticism of these is more implicit than stated. A more forceful definition of the “problem” of erotic charis, for example, would have helped unify this discussion with that of erotic charis in Aeschylus. Her discussion of Pindar and Bacchylides (6, “Epinician Charis”), perhaps the high point of the book, shows the richest ties to the multi-dimensional Homeric charis; here we return clearly to the topic of [End Page 172] beauty, see the pertinence of some of the cult information, and sense the transformational dynamics of charis as profoundly important for this genre of poems. She leaves somewhat open, however, the question of whether charis is a single thing in Pindar. The chapter on Aeschylus (7, “Charis in the Oresteia”) presents a powerful reading of different kinds of charis in conflict, private versus public, resulting in a unified view of the trilogy as a whole. Once more we note different senses of charis, but in a way that highlights their collision: the duality of charis is further brought into relation with other dualities, such as that of dikê. This chapter connects well with other parts of the book; erotic and false charis become important issues.If there is a criticism to make of this book, it is that MacLachlan does not do quite enough to work out the relations between her provocative thesis and her discussions of particular poems. Some sections are too dissertation-like in presenting evidence, and more thought about the... (shrink)

Too many patients are injured in the course of care. Clinicians may mistakenly cause new harm to a patient or fail to take established steps to improve the presenting condition. Medical institutions within which they work may lack mechanisms to reduce errors or prevent them from harming patients. Many, perhaps even most, injuries are preventable, probably numbering in the hundreds of thousands a year for hospital care alone. Long ignored by medical practitioners and health-care payers and little appreciated by the (...) public, the problem of medical injury is finally receiving high-level policy attention.

BackgroundSarcomas are a diverse group of neoplasms that vary greatly in clinical presentation and responsiveness to treatment. Given the differences in the sites of involvement, rarity, and treatment modality, a multidisciplinary approach is required. Previous literature suggests patients with sarcoma suffer from poorer quality of life especially physical and functional wellbeing. Adolescent and young adult patients are an underrepresented population in cancer research and have differing factors influencing QoL.MethodsRetrospective analysis of Young Adult patients enrolled in the Sarcoma Tissue Repository at (...) University of Iowa. QoL was assessed using the self-report FACT-G questionnaire at enrollment and 12 months post-diagnosis; overall scores and the 4 wellbeing subscales were calculated. Linear mixed effects models were used to measure the association between the rate of change in FACT-G subscale scores and baseline clinical, comorbidity, and treatment characteristics.Results49 patients were identified. 57.1% of patients had a malignancy involving an extremity. Mean FACT-G scores of overall wellbeing improved from baseline to 12 months. Social and emotional wellbeing did not differ significantly between baseline and 12 months. Physical wellbeing and functional wellbeing scores improved from baseline to 12 months. No difference was seen for FACT-G overall scores for age, sex, laterality, marital status, performance status, having children, clinical stage, limb surgery, chemotherapy, or tumor size. A difference was demonstrated in physical wellbeing scores for patients with baseline limitation compared to those with no baseline limitation. A difference was demonstrated in social wellbeing based on anatomical site.ConclusionYoung adults with sarcoma treated at a tertiary center had improvements in overall reported QoL at 12 months from diagnosis. Overall baseline QoL scores on FACT-G were lower than the general adult population for YA patients with sarcoma but at 12 months became in line with general population norms. The improvements seen merit further investigation to evaluate how these change over the continuum of care. Quality of life changes may be useful outcomes of interest in sarcoma trials. (shrink)

From computerized medical records to databases of pharmacological interactions and automated provisional EKG readings, the emergence of information technology has significantly altered the practice of medicine. Information technology has been widely used to enhance diagnosis and treatment and to improve communication between providers. The advent of the Internet also brings far-reaching implications for patient–physician communication, challenging physicians, patients, and policymakers to consider its impact on the delivery of medical care and the therapeutic relationship. A new set of practices by patients (...) and physicians is unfolding in cyberspace, ranging from the use of e-mail to communicate between physicians and patients in an existing relationship to one-to-one consultations with an anonymous physician and ongoing online treatment, such as psychotherapy. These practices are emerging in both the for-profit and not-for-profit spheres. (shrink)
