Per generazioni i filosofi hanno sostenuto che gli esseri umani sono essen­zialmente identici – che condividono, cioè, la stessa natura – e che questa somiglianza essenziale è estremamente importante. Periodicamente, i filo­sofi hanno proposto di fondare l’essenziale identità degli esseri umani sulla biologia. Nel saggio viene difesa la tesi secondo cui se, quando si parla di ‘biologia’, ci si riferisce ai pronunciamenti tecnici dei biologi di profes­sione – in particolare dei biologi evoluzionisti – semplicemente non è vero che tutti gli (...) organismi che appartengono alla specie homo sapiens in quan­to specie biologica siano essenzialmente identici. Generations of philosophers have argued that all human beings are essen­tially the same – that is, they share the same nature – and that this essen­tial similarity is extremely important. Periodically, philosophers have pro­posed to base the essential sameness of human beings on biology. In this essay it is argued that if ‘biology’ is taken to refer to the technical pro­nouncements of professional biologists – in particular evolutionary biolo­gists – it is simply not true that all organisms that belong to homo sapiens as a biological species are essentially the same.

This is a book review of David Hull's edited volume of collected papers, Science and Selection.

Philosophers of science frequently bemoan (or cheer) the fact that today, with the supposed collapse of logical empiricism, there are now ;;10 grand systems. However, although this mayor may not be true, and if true mayor may not be a cause for delight, no one should conclude that the philosophy of science has ground to a halt, its problems exhausted and its practioners dispirited. In fact, in this post­ Kuhnian age the subject has never been more alive, as we work (...) with enthusiasm on special topics, historical and conceptual. And no topic has grown and thrived quite like the philosophy of biology, which now has many students in the field producing high-quality articles and monographs. The success of this subject is due above all to the work and influence of one man: David Hull. In his own writings and in the support he has given to others, he has shown true leadership, in the best Platonic sense. It is now twenty years since Hull fnt gave his seminal paper 'What the philosophy of biology is not', and to mark that point and to show our respect, gratitude and affection to its author, a number of us who owe much to Hull decided to produce a volume of essays on and around themes to which Hull has spoken.

The marketplace of ideas theoy has been utilized as one means to justify,from a societal perspective, contempora y public relations practice. Proponents confend that practitioners serve society in true Miltonian fashion by helping clients inject their views into that marketplace. One must question, however, whether afunctional marketplace of ideas exists relative to the public relations process. Further, by focusing ethical questions on individualistic practitioner behavior relative to that marketplace, practitioners may not be paying sulyicient attention to the demands of distributive (...) and social justice.

Before being executed by the Nazis at the age of 39, Dietrich Bonhoeffer had produced enough material, according to Howell, to fill 16 volumes of theological reflections. Nevertheless, Howell noted, Dietrich Bonhoeffer is not a household name. That is unfortunate. One of Bonhoeffer's most inspiring efforts-from the perspective of mass media ethics-centered around his unfinished attempt to define "what is meant by telling the truth." As is often the case with truly outstanding thinkers, his reflections in this regard appear even (...) more timely today than when he composed them well over 50 years ago. (shrink)

This article explores the intellectual life of Max Harold Fisch, the twentieth-century American scholar of Giambattista Vico and Charles S. Peirce. Fisch was a thinker with fundamental commitments to both history and philosophy. The claim here is that his life exemplifies a constitutive tension in the work of intellectual historians, who operate in the interstice between these two disciplines. What we learn is that intellectual historians may have a double investment both in the filigree of particular historical contexts and in (...) the principles that emerge in and then detach from those contexts. The article explores this double investment by following it through five decades of Fisch’s intellectual labor between 1930 and 1980. (shrink)

Joseph Priestley, the eighteenth-century scientist who discovered oxygen, was one of the most remarkable thinkers of his time. This collection of essays by a team of experts covers the full range of his work in the fields of education, politics, philosophy, and theology, and firmly re-establishes him as a major intellectual figure.

Background Various authorities recommend the participation of patients in promoting patient safety, but little is known about health care professionals' (HCPs') attitudes towards patients' involvement in safety-related behaviours. Objective To investigate how HCPs evaluate patients' behaviours and HCP responses to patient involvement in the behaviour, relative to different aspects of the patient, the involved HCP and the potential error. Design Cross-sectional fractional factorial survey with seven factors embedded in two error scenarios (missed hand hygiene, medication error). Each survey included two (...) randomized vignettes that described the potential error, a patient's reaction to that error and the HCP response to the patient. Setting Twelve hospitals in Switzerland. Participants A total of 1141 HCPs (response rate 45%). Measurements Approval of patients' behaviour, HCP response to the patient, anticipated effects on the patient–HCP relationship, HCPs' support for being asked the question, affective response to the vignettes. Outcomes were measured on 7-point scales. Results Approval of patients' safety-related interventions was generally high and largely affected by patients' behaviour and correct identification of error. Anticipated effects on the patient–HCP relationship were much less positive, little correlated with approval of patients' behaviour and were mainly determined by the HCP response to intervening patients. HCPs expressed more favourable attitudes towards patients intervening about a medication error than about hand sanitation. Conclusions This study provides the first insights into predictors of HCPs' attitudes towards patient engagement in safety. Future research is however required to assess the generalizability of the findings into practice before training can be designed to address critical issues. (shrink)

In the early twentieth century psychology became the study of "behavior." This article reviews developments within animal psychology, functional psychology, and American society and culture that help explain how a term rarely used in the first years of the century became not only an accepted scientific concept but even, for many, an all-encompassing label for the entire subject matter of the discipline. The subsequent conceptual and linguistic activity of John B. Watson, Edward C. Tolman, Clark L. Hull, and B.F. Skinner, (...) as they attempted to explain "behavior" throughout the course of the twentieth century, is then discussed. Finally, the article suggests the need for greater conceptual and linguistic diversity in psychology. In this last regard, reference is made to cognition and consciousness, to William James and John Dewey, and to the fact that prediction and control might not be the most relevant aims of contemporary psychology.

E. O. Wilson argues that we must use scientifically based reason to solve the values dilemma created by the loss of a transcendent foundation for values. Peter Singer allows that sociobiology can help us understand the evolutionary origin of ethics, but denies the claim that sociobiology or any science can furnish us with ultimate ethical principles. We argue that Singer's critique of Wilson's attempt to bridge the gap between fact and value using empirical reason is unconvincing and that Singer's own (...) ethical principle of disinterestedness requires major support from empirical reason and is not sustainable by pure reason alone.

Hull et al.'s analysis of operant behavior in terms of interaction and replication does not seem consistent with a genuine selection model. The putative replicators do not replicate, and the overall process is more reminiscent of directed mutation than of natural selection. General analogies between natural selection and operant reinforcement are too superficial to be of much scientific use.

Seeking parallels among disciplines can have both risks and benefits. Finding parallels may be a vacuous exercise in categorization, generating no new insights. And pointing to analogous functions may cause us to treat them as homologous. Hull et al. have provided a basis for the generation of insights in different selectionist areas, without confusing analogy with homology.

Many analogies exist between the process of evolution by natural selection and of learning by reinforcement and punishment. A full extension of the evolutionary analogy to learning to include analogues of the fitness, genotype, development, environmental influences, and phenotype concepts makes possible a single theory of the learning process able to encompass all of the elementary procedures known to yield learning.

The interaction of the organism with the environment requires not only reactive, but also active behavior which helps subject to meet the challenge of the uncertainty of the environment. A positive feedback between active behavior and immune system makes the selection process effective.

In their account of learning and behavior, the authors define an interactor as emitted behavior that operates on the environment, which excludes Pavlovian learning. A unified neural-network account of the operant-Pavlovian dichotomy favors interpreting neurons as interactors and synaptic efficacies as replicators. The latter interpretation implies that single-synapse change is inherently Lamarckian.

Activity anorexia illustrates selection of behavior at the biological, behavioral, and neural levels. Based on evolutionary history, food depletion increases the reinforcement value of physical activity that, in turn, decreases the reinforcement effectiveness of eating – resulting in activity anorexia. Neural opiates participate in the selection of physical activity during periods of food depletion.

Criticized as a nostalgic anachronism by those who oppose her version of political theory and lauded as symbol of direct democratic participation by those who favor it, the Athenian polis features prominently in Hannah Arendt's account of politics. This essay traces the origin and development of Arendt's conception of the polis as a space of appearance from the early 1950s onward. It makes particular use of the Denktagebuch, Arendt's intellectual diary, in order to shed new light on the historicity of (...) one of her central concepts. The article contends that both critics and partisans of Arendt's use of the polis have made the same mistake: they have presumed that the polis represents a space of face-to-face immediacy. In fact, Arendt compared the polis to a series of analogues, many of which are not centered on direct exchanges between political actors and spectators. As a result, Arendt's early work on the polis turns out to anticipate many of the concerns of her later work on judgment, and her theory of the polis becomes a theory of topics. (shrink)
