Recent results from two different studies show evidence of strong emotional engagement in moral dilemmas that require personal involvement or ethical problems that involve significant inter-personal issues. This empirical evidence for a connection between emotional engagement and moral or ethical choices is interesting because it is related to a fundamental survival mechanism rooted in human evolution. The results lead one to question when and how emotional engagement might occur in a professional ethical situation. However, the studies employed static dilemmas or (...) problems that offered only two choices whose outcome was certain or nearly so, whereas actual problems in professional ethics are dynamic and typically involve considerable uncertainty. The circumstances of three example cases suggest that increasing personal involvement and uncertainty could have been perceived as changes, threats, or opportunities and could therefore have elicited an emotional response as a way to ensure the reputation, integrity or success of oneself or a group to which one belongs. Such emotional engagement is only suggested and more studies and experiments are required to better characterize the role of emotional engagement in professional ethics. (shrink)

This paper proposes that virtue theories of argumentation and theories of visual argumentation can be of mutual assistance. An argument that adoption of a virtue approach provides a basis for rejecting the normative independence of visual argumentation is presented and its premisses analysed. This entails an independently valuable clarification of the contrasting normative presuppositions of the various virtue theories of argumentation. A range of different kinds of visual argument are examined, and it is argued that they may all be successfully (...) evaluated within a virtue framework, without invoking any novel virtues. (shrink)

Nanotechnology is developing far faster than our understanding of its effects. This lapping of our understanding by speedy development is typical of new technologies, and in the United States we let development occur, introducing new artifacts into the world, without any serious attempt to understand beforehand their effects, long-term or short-term. We have been willing to pay the price of pushing the technological envelope, but pushing the nanotechnological envelope has some special risks, requiring more caution.
