Through the process of domestication the genetic make-up of farm animals can be changed by means of either selective breeding or genetic engineering. This paper is about the ethical limits to such genetic changes. It is suggested that the ethical significance of domestication has become clear recently in the light of genetic engineering, but that the problem has been there all along. Two ethical approaches to domestication are presented, genetic integrity and animal welfare. It is argued that the welfare approach (...) is superior. Finally, five ethical hypotheses based on the welfare approach are presented. (shrink)

OBJECTIVES: Early-emerging, temperamental differences in fear-related traits may be a heritable vulnerability factor for anxiety disorders. Previous research indicates that the serotonin transporter promoter region polymorphism is a candidate gene for such traits. METHODS: Associations between 5-HTTLPR genotype and indices of fearful child temperament, derived from maternal report and standardized laboratory observations, were examined in a community sample of 95 preschool-aged children. RESULTS: Children with one or more long alleles of the 5-HTTLPR gene were rated as significantly more nervous during (...) standardized laboratory tasks than children who were homozygous for the short alleles. Children homozygous for the short alleles were also rated as significantly shyer, by maternal report, than those with at least one copy of the long allele of the 5-HTTLPR gene. CONCLUSIONS: This study extends the literature linking the short alleles of the serotonin transporter promoter region polymorphism to fear and anxiety-related traits in early childhood and adulthood, and is one of very few studies to examine the molecular genetics of preschoolers' temperament using multiple measures of traits in a normative sample.

Abela accepts Fine’s account of realism and instrumentalism, but thinks that we can reject the Natural Ontological Attitude by distinguishing the theoretical attempt to make sense of scientific practice from choosing the attitude we bring to the debate, or to science itself. But Abela’s attitudes are vulnerable to Fine’s criticisms of the philosophical positions. However, if we take attitude as contrastive and as full‐blooded enough to lead to different behaviour we can see a gap in Fine’s position. He cannot tell (...) us why it is science that he trusts. When we look more widely, the philosophical positions might be seen as ways of justifying that trust. (shrink)

Text of and reflection on the 1981 encounter between Hans-Georg Gadamer and Jacques Derrida, which featured a dialogue between hermeneutics in Germany and post-structuralism in France. <br.

Informal logicians recognise the frequent use of unstated assumptions; some (e.g. Fisher) also recognise entertained arguments and recommend a suppositional approach (such as Mackie's) to conditional statements. It is here argued that these two be put together to make argument diagrams more accurate and subtle. Philosophical benefits also accrue: insights into Jackson's apparent violations of modus tollens and contraposition and McGee's counterexamples to the validity of modus ponens.
