Deafness as a test case

In the general discussion on prenatal selection in Chapter 3, it became clear that many ethical theorists draw a line between moral and legal norms. Moral duties cannot be automatically translated into legal obligations; and legal permissions do not always imply moral acceptance. This is clearly visible in the case of ‘deaf embryos’ – in the attempt of parents to create children who would be deaf like them.

This chapter studies the ethics of selecting ‘deaf embryos’ and argues that the deep moral disagreement visible in contemporary bioethical debate on the possibility of choosing deafness should probably be ­recognised and accepted, not drowned in feuds. I will first describe, in Sections 4.2 and 4.3, the background of the practice in emerging reproductive technologies and sketch the main moral and legal stands in its assessment and regulation. I will then go on to examine, in Sections 4.4 and 4.5, the moral justifications that have been given to the two competing views on the issue: the ‘medical view’ and the ‘social view’. The first of these states that selecting ‘deaf embryos’ is morally dubious although it should, as far as the law is concerned, be left to the discretion of the parents. The second contends that the practice is morally unproblematic or even commendable but agrees that the law should not interfere with parental choice.
