Living longer: age retardation and autonomy

Value Lexicality and Human Enhancement

One idea discussed in ethical theory is that values can be put in a lexical ordering. One value that ranks higher in a lexical ordering always outweighs a lower-ranked value, regardless of the amount or intensity of both values. An account of value lexicality that focuses on the practical applicability of this concept will be developed and subsequently applied to the debate about life extension technologies and human enhancement in general. Finally, a sketch of a heuristic will be provided that shows how the concept of value lexicality could be of assistance when assessing the quality of arguments in various fields of applied ethics, one of which is the debate about human enhancement.
