There is great skepticism about the admittance of expert normative ethics testimony into evidence. However, a practical analysis of the way ethics testimony has been used in courts of law reveals that the skeptical position is itself based on assumptions that are controversial. We argue for an alternative way to understand such expert testimony. This alternative understanding is based on the practice of clinical ethics.

Dr Agich takes up a previous difficult case related by Dr Kottow in an earlier issue of the Journal. He analyses the three ethical problems as presented in the case and offers his own opinion of it as well as his own conclusions with regard to the medical ethical aspects of it. Unlike Dr Kottow, Dr Agich's reading of the case indicates that the application of the principle of informed consent does not rule out ethical decisions for the physician, but (...) emphasizes the relevance of ethical analysis beyond the issue of informed consent.

This article is an attempt to clarify a confusion in the brain death literature between logical sufficiency/necessity and natural sufficiency/necessity. We focus on arguments that draw conclusions regarding empirical matters of fact from conceptual or ontological definitions. Specifically, we critically analyze arguments by Tom Tomlinson and Michael B. Green and Daniel Wikler. which, respectively, confuse logical and natural sufficiency and logical and natural necessity. Our own conclusion is that it is especially important in discussing the brain death issue to observe (...) the distinction between logical and natural sufficiency/necessity in a strict fashion.

This book offers the first historical treatment and analytic analysis of the problem of the criterion. It provides analyses of the ancient and modern characterizations of the problem and a resolution of each. My purpose is to show that there are at least two versions of the problem, one posed by a Pyrrhonian sceptic and one by a dogmatic sceptic. I show that both versions have a dissolution. Then, by examining the presuppositions of the dogmatic sceptic, I demonstrate that the (...) sceptic's position is self-undermining. I argue that meta-epistemological scepticism is much less reasonable than some forms of meta-epistemic cognitivism. (shrink)

In 1926, Mally presented the first formal system of deontic logic. His system had several consequences which Mally regarded as surprising but defensible. It also, however, has the consequence that A is obligatory if and only if A is the case, which is unacceptable from the point of view of any reasonable deontic logic. We describe Mally's system and discuss how it might reasonably be repaired.

The information-theoretic point of view proposed by Leibniz in 1686 and developed by algorithmic information theory (AIT) suggests that mathematics and physics are not that different. This will be a first-person account of some doubts and speculations about the nature of mathematics that I have entertained for the past three decades, and which have now been incorporated in a digital philosophy paradigm shift that is sweeping across the sciences.

During the last decade neurotransplantation has developed into a technique with the possible potential to repair damaged or degenerating human brain. Effective neurotransplantation has so far been based on the use of fetal brain tissue derived from aborted embryos or fetuses. The ethical issues related to this new therapeutic approach therefore not only concern the possible adverse side effects for a neural graft-receiving patient, but also the relationship between the requirements for fetal tissue and the decision-making process for induced abortion. (...) Although for decades human embryos and fetuses have been the subject of biomedical studies, and, in principle, their use has therefore not been seen as ethically objectionable, the above points made it necessary to reconsider the moral issues. The present paper points out several of these issues, both from the donor and acceptor (patient) point of view. The conclusion is that under a series of restrictions intended to prevent the use of grafts from encouraging induced abortions and to maintain high standards of respect for life and human dignity, neurotransplantation using embryonic or fetal brain tissue parts cannot be rejected on moral grounds.

Some years ago, Lokhorst proposed an intuitionistic reformulation of Mally's deontic logic. This reformulation was unsatisfactory, because it provided a striking theorem that Mally himself did not mention. In this paper, we present an alternative reformulation of Mally's deontic logic that does not provide this theorem.

The familiar issue of corporate social responsibility takes on a new topic. Added to the list of concerns from affirmative action and environmental integrity is their growing contributions to education. At first glance, the efforts may appear to be ordinary gestures of communal good will in terms of providing computers, sponsoring book covers, and interactive materials provided by Scholastic Magazine. A closer view reveals a targeted market of student life who are vulnerable to commercials placed in these formats. Among the (...) most effective corporate intervention is Channel One News. It offers a newsworthy show but with mandatory commercial viewing. This increasing trend of corporations intervening to assist schools that need more money and/or equipment is disingenuous.In this essay, I present the background of this commercialization of education and demonstrate the violations against student autonomy and integrity. Although there may be utilitarian merits to some interventions, I argue that these infringe upon the moral value of personhood. Advertising in schools in its current practice is immoral on deontological grounds. (shrink)

Hi everybody! It's a great pleasure for me to be back here at the new, improved Santa Fe Institute in this spectacular location. I guess this is my fourth visit and it's always very stimulating, so I'm always very happy to visit you guys. I'd like to tell you what I've been up to lately. First of all, let me say what algorithmic information theory is good for, before telling you about the new version of it I've got.
