Few subjects have generated so many newspaper headlines and such heated controversy as the treatment, or non-treatment, of handicapped newborns. In 1982, the case of Baby Doe, a child born with Down's syndrome, stirred up a national debate in the United States, while in Britain a year earlier, Dr. Leonard Arthur stood trial for his decision to allow a baby with Down's syndrome to die. Government intervention and these recent legal battles accentuate the need for a reassessment of the complex (...) issues involved. This volume--by two authorities on medical ethics--presents a philosophical analysis of the subject based on particular case studies. Addressing the doctrine of the absolute sanctity of life, Singer and Kuhse examine some actual cases where decisions have been reached; consider the criteria for making these decisions; investigate the differences between killing and letting die; compare Western attitudes and practices with those of other cultures; and conclude by proposing a decision-making framework that offers a rational alternative to the polemics and confusion generated by this highly controversial topic.

For millennia, philosophers have speculated about the origins of ethics. Recent research in evolutionary psychology and the neurosciences has shed light on that question. But this research also has normative significance. A standard way of arguing against a normative ethical theory is to show that in some circumstances the theory leads to judgments that are contrary to our common moral intuitions. If, however, these moral intuitions are the biological residue of our evolutionary history, it is not clear why we should (...) regard them as having any normative force. Research in the neurosciences should therefore lead us to reconsider the role of intuitions in normative ethics. (shrink)

Welfare biology is the study of living things and their environment with respect to their welfare. Despite difficulties of ascertaining and measuring welfare and relevancy to normative issues, welfare biology is a positive science. Evolutionary economics and population dynamics are used to help answer basic questions in welfare biology : Which species are affective sentients capable of welfare? Do they enjoy positive or negative welfare? Can their welfare be dramatically increased? Under plausible axioms, all conscious species are plastic and all (...) plastic species are conscious. More complex niches favour the evolution of more rational species. Evolutionary economics also supports the common-sense view that individual sentients failing to survive to mate suffer negative welfare. A kind of God-made fairness between species is also unexpectedly found. The contrast between growth maximization, average welfare, and total welfare maximization is discussed. It is shown that welfare could be increased without even sacrificing numbers. Since the long-term reduction in animal suffering depends on scientific advances, strict restrictions on animal experimentation may be counter-productive to animal welfare. (shrink)
