Enhancement is a hot topic in biomedical ethics, though the academic conversation is coloured by a surprisingly strong – even reactionary – conservatism. On the one hand it probably is a good thing to have some critical scrutiny of the techno utopians' claims. On the other hand, should we – can we? – distinguish between good 'treatment' and bad 'enhancement', as Michael Sandel has argued? Is there really a difference between glasses and laser eye surgery apart from semantics? Does the capability to 'hear' non-acoustically constitute some kind of infringement of the human telos? And if so, so what? I sometimes wonder whether these concerns amount to anything more than the insinuation of a conservative vision of the human condition that would be challenged in any other conversation in moral philosophy.
Nonetheless, thinking about enhancement can be fun, and even enlightening. As with good science fiction, imagining changes to the human condition pushes us to look more clearly at what we already have, and how we might use it better. Take moral enhancement. Is it possible to make humans morally better than we are now? What might that look like and are there any dystopian risks to look out for?
‘Morality' seems to comprise three distinct dimensions towards which an enhancement project could be directed: theoretical reason, practical reason, and self-command. It's important to note at the beginning that such a project doesn't depend on science fiction technologies – special IQ pills, brain implants, and so forth might be part of this in the future, but moral enhancement is an ancient project with a long and mixed track record of developing enhancement technologies, including formal education, role-modelling, parenting, physical exercise, religious rituals, nutritional supplements, philosophical 'leisure', judicial punishment, Cognitive Behavioural Therapy, and so on.
