The illiberality of perfectionist enhancement

With the rapid advance of bio-genetic technology, it will soon be possible for parents to design children who are born with certain genetic traits. This raises the question whether parents should be allowed to use this technology to engineer their children as they please. In this context it is often thought and argued that liberalism, which has a reputation for being permissive of all kinds of practices, grants parents the right to do so. However, I will argue that, on an understanding of liberalism that is identical to the one used by the defenders of genetic design, liberals should wary of such practices. Liberalism, in its most general form, requires that any time individuals exercise power over others they justify it without relying on any particular conception of what a good life is. When we design children to have certain traits that are only useful for realising some conceptions of the good life, we are implicitly endorsing those conceptions. Hence this practice cannot be justified in neutral terms, and liberals should be sceptical of it. Only when we engineer our children to have traits that are useful for all conceptions of the good life can liberals allow the use of this new technology. Indeed, liberalism holds that this is morally required.

Desert, democracy, and consumer surplus

If one wishes to give individuals what they deserve, one must find some way of appraising those characteristics that render them deserving. In modern democratic societies, it seems attractive to base this appraisal on an aggregation of the valuations individuals hold of the desert bases under consideration. Some have argued that the market can provide such an appraisal. However, I argue that the market does not provide a satisfactory democratic appraisal that is relevant for desert, as it allows for the existence of net consumer surplus. Nevertheless, I submit that a procedure that does not leave any net consumer surplus would succeed where the market fails. Taking the average valuation of the individuals in society for a given desert base would meet this requirement. Hence, I claim that such a procedure can provide the satisfactory democratic appraisal that the market cannot, and can be used to give individuals what they deserve.
