The experience of newborn screening for Krabbe disease in New York State demonstrates the ethical problems that arise when screening programs are expanded in the absence of true understanding of the diseases involved. In its 5 years of testing and millions of dollars in costs, there have been very few benefits, and the testing has uncovered potential cases of late-onset disease that raise difficult ethical questions in their own right. For these reasons, we argue that Krabbe screening should only be (...) continued as a research project that includes the informed consent of parents to the testing. (shrink)

The existence of consciousness in animals may have been overlooked. Continuity in consciousness between humans and animals is predicted by evolutionary theory. However, there are specific methodological difficulties associated with investigating such a phenomenon: it cannot be directly measured; animals, unlike humans, cannot directly tell us about their conscious experience; experiments which have made comparisons to human consciousness cannot detect consciousness of a different form; application of the law of parsimony in science has traditionally led to the conclusion that it (...) does not exist.

The time taken to react voluntarily to a stimulus is far longer than can be accounted for by ordinary processes of nerve conduction and synaptic delay, and varies unpredictably from trial to trial. Though random, the distribution of reaction times usually follows a relatively simple law, which in turn can be explained by the LATER model, in which a decision signal, representing belief in the existence of the target, rises in response to incoming sensory evidence from an initial value to (...) a criterion level at which action is initiated. But the rate of rise fluctuates randomly from trial, to an extent that cannot be explained by sensory noise at the input. These conclusions, confirmed by recording from neurons in the frontal eye fields, suggest that the randomness of reaction time is due to a deliberate, gratuitous, neural process which confers certain biological advantages as well as having implications for general ideas about the nature of ‘free will'.

The paper uses questionnaire responses provided by a sample of ethical investors to investigate willingness to sacrifice ethical considerations for financial reward. The paper examines the amount of financial reward necessary to cause an ethical investor to accept a switch from good ethical performance to poor ethical performance. Conjoint analysis is used to allow quantification of the utilities derived from different combinations of ethical and financial performance. Ethical investors are shown to vary in their willingness to sacrifice ethical for financial (...) performance, and hence to display more heterogeneity than the all-encompassing ‘ethical’ label implies. Because of the existence of sub-groups of ethical investors with different attitudes towards financial reward, an attempt has been made to associate observable investors’ characteristics with their level of willingness to trade-off morality for cash. One sub-group of investors in particular appears highly resistant to the idea of accepting higher financial return as compensation for poor ethical performance. This unwillingness casts doubt on Jensen and Meckling’s widely reported claim that trade-off behaviour is ubiquitous in all areas of life. (shrink)

Plato was born around 2,500 years ago. He lived in a small city-state in Greece and busied himself with the problems of his fellow Greeks, a people living in scattered cities around the Mediterranean and the Black Sea. In all he tried to do for the Greeks he failed. Why, then, should people in the modern world bother to read what he had to say? Does it make sense to go to a Greek thinker for advice on the problems of (...) an age so different from his own? To anyone who has questioned the relevance of Plato to the modern world Richard Crossman’s lively book provides a brilliant reply. The problems facing Plato’s world bear striking parallels to ours today, the author maintains, so who better to turn to than Plato, the most objective and most ruthless observer of the failures of Greek society. Crossman’s engaging text provides both an informed introduction to Greek ideas and an original and controversial view of Plato himself. (shrink)
