This paper is based on two presentations under the auspices of thf Edinburgh Medical Group in 1976. Dr Noble and Professor Mason, explore the incidence of incest and society's attitudes to it from legal, anthropological, medical and social viewpoints. They place this in a world context by looking at the universal prohibition of incest and the theories related to that taboo. In conclusion, they suggest that there seem to be sufficient sensible grounds on which to base a reappraisal of attitudes (...) to incest. Their conclusions are in turn appraised by brief commentaries from a moral philospher and a psychiatrist. (shrink)
