In a near-future world of bionics and biotechnology, the main ethical and political issue will be the definition of who we are. Could biomedical enhancements transform us to such an extent that we would be other than human? Habermas argues that any genetic enhancement intervention that could potentially alter ‘human nature’ should be morally prohibited since it alters the child’s nature or the very essence that makes the child who he is. This practice also commits the child to a specific (...) life project or, in any case, it puts specific restrictions on his freedom to choose a life of his own. Ultimately, genetic enhancement jeopardizes the very foundations of moral equality. I contend that Habermas’ argument is based either on a series of presuppositions that imply a gross misunderstanding of evolution or the relevant factual information cocerning the action we are about to morally assess is not empirically supported. Hence, the argument from human nature is based on a series of false or problematic assumptions, and, as such, it fails to play the normative role intended by Habermas. (shrink)

Moral and political philosophers no longer condemn harm inflicted on nonhuman animals as self-evidently as they did when animal welfare and animal rights advocacy was at the forefront in the 1980s, and sentience, suffering, species-typical behavior, and personhood were the basic concepts of the discussion. The article shows this by comparing the determination with which societies seek responsibility for human harm to the relative indifference with which law and morality react to nonhuman harm. When harm is inflicted on humans, policies (...) concerning negligence and duty of care and principles such as the ‘but for’ rule and the doctrine of double effect are easily introduced. When harm is inflicted on nonhumans, this does not happen, at least not any more. As an explanation for the changed situation, the article offers a shift in discussion and its basic terminology. Simple ethical considerations supported the case for nonhuman animals, but many philosophers moved on to debate different views on political justice instead. This allowed the creation of many conflicting views that are justifiable on their own presuppositions. In the absence of a shared foundation, this fragments the discussion, focuses it on humans, and ignores or marginalizes nonhuman animals. (shrink)
