In his Paralipomena Johannes Kepler reported an experimentum that he had seen in the Dresden Kunstkammer. In one of the rooms there, which had been turned in its entirety into a camera obscura, he had witnessed the images formed by a lens.

I argue that this experiment allowed Kepler to sort out the confusion between images 'in the air'—referring to the geometrical locus of images in the perspectivist tradition of optics—and the experimentally produced 'projected images', which were empirically familiar but conceptually alien to perspectivist optics.

In the following Kepler suggests a number of different readings of Carroll’s Alice books that would be useful to those attempting to integrate philosophy into an existing curriculum.

Medical ethics involve more than a prohibition against advertising or solicitation of patients, or a limit on the height of the letters on a doctor's office door. The true ethics of health care are the fundamental values that guide-or should guide-physicians in every aspect of their interaction with patients, their families, and society at large. Professional ethics is a complex and controversial issue, but one that must be dealt with in an era of increasing skepticism about the practice of medicine. (...) Medical Stewardship is a carefully reasoned historical and philosophical inquiry into the origins of our notions of medical ethics, and the ways in which a true sense of the doctor's proper role can be restored. Tracing the development of medical ethics from ancient times to the modern era, Dr. Kepler consides them in relation to the medical profession of today. He considers several areas seldom discussed in works on medical ethics: the exploitation of the patient, preventive versus disease treatment, ethical problems in medical education, drug abuse by physicians, the ethics of organized medicine, and some important but under-utilized roles of the physician.

In this article, I highlight systemic oppression related to identity construction and ontological performativity. I introduce the concept of inter-relationality as a discursive tool that builds upon intersectionality, feminist theology, and quantum entanglement theory. For a case study, I recount my experience observing sex-trafficked boys in Thailand in order to demonstrate the analytical model I present. My chief analytical guiding principle in the treatment of the case study is the way masculinity operates to re-enforce oppression. I propose queering masculinity using (...) an inter-relational perspective for the purpose of de-constructing oppressive systems and replacing them with liberative ones. (shrink)

Originally published in 1986. All students of social science must confront a number of important philosophical issues. This introduction to the philosophy of the social sciences provides coherent answers to questions about empiricism, explanation and rationality. It evaluates contemporary writings on the subject which can be as difficult as they are important to understand. Each chapter has an annotated bibliography to enable students to pursue the issues raised and to assess for themselves the arguments of the authors.

Quantifiers are a test case for an interface between psychological questions, which attempt to specify the numerical content that supports the semantics of quantifiers, and linguistic questions, which uncover the range of possible quantifier meanings allowable within the constraints of the syntax. Here we explore the development of comprehension of most in English, of particular interest as it calls on precise numerical content that, in adults, requires an understanding of large exact numerosities (e.g., 23 blue dots and 17 yellow is (...) an instance of “most of the dots are blue”). In a sample of 100 children 2 to 5 years of age we find that (a) successful most comprehension in cases with two salient subsets is achieved at 3 years, 7 months of age, and (b) most comprehension is independent of knowledge of large exact number words; that is, knowledge of large exact number words is neither necessary, as evidenced by children who understand “most” but not “four,” nor sufficient, as evidenced by children who understand “nine” but not “most.”.

It has become fashionable to question attempts to derive internationally agreed duties of clinical care from more general theories of human rights. For example, some argue that such attempts risk moral abstraction through their neglect for the importance of culture and community in shaping moral consciousness and are thus often unhelpful in the resolution of concrete moral dilemmas within medicine. Others denounce the importance of general moral principles altogether in bioethics and attempt to articulate what are claimed to be more (...) practical approaches to resolving moral conflict. This paper challenges such arguments. It does so through arguing that: i) all humans everywhere have the same basic human needs; ii) the satisfaction of these needs varies with culture; iii) the imputation of moral duties on others entails respect for their right to basic need satisfaction, including the right to choose between cultures; iv) internationally accepted clinical duties of care embrace presumptions about the duties and rights of patients which follow from these more general principles and v) problems of moral indeterminacy that arise from putting these principles into practice can be resolved through associated procedural policies of rational negotiation and compromise. The moral importance and practicality of respect for individual human rights within the practice of medicine is thus defended. Indeed, the paper concludes by arguing that without belief in human rights linked to a theory of basic human needs, communitarian theories of morality are incoherent. (shrink)

Invited media scholars and journalists examine the general issue of nuclear waste, risk and the sicentific promises that were made, but not kept, about safe disposal. The mass media uncovered and reported on nuclear waste problems at Rocky Flats in Colorado and Hanford in Washington. Two environmental journalists review efforts to expose problems at these sites, how secrecy hampered reporting, and the effects of media coverage on nearby residents. An environmental communications scholar evaluates media coverage, the role of the U.S. (...) Department of Energy, and the impact of secrecy on public risk perceptions and attitudes toward government nuclear waste policies. (shrink)

The intensity of the opposition to health reform in the United States continues to shock and perplex proponents of the Patient Protection and Affordable Care Act. The emotion and the apocalyptic rhetoric, render civil and evidence-based debate over the implications and alternatives to specific provisions in the law difficult if not problematic. The public debate has largely barreled down two non-parallel yet non-intersecting paths: opponents focus on their fear of government expansion in the future if PPACA is implemented now, while (...) proponents focus on the urgency and specifics of our health care market problems and the limited number of tools we have to address them. Frustration on both sides has led opponents to deny the seriousness of our health system’s problems and proponents to ignore the risk of governmental overreach. These non-intersecting lines of argument are not moving us closer to a desired and necessary resolution. (shrink)
