Reviews of philosophical books run the risk of being either excessively and unconstructively critical or superficially praiseworthy. To avoid both these risks, we test the approach outlined by Häyry in his book Rationality and the Genetic Challenge: Making People Better? by applying it to an eighth genetic challenge, namely, a variation of the genetic enhancement challenge discussed by Häyry as it applies to sports. We assess whether genetic enhancement in sports should be conceived as an eighth wonder or an eighth (...) cardinal sin that stems from the interaction between genetics and society, question whether Häyry’s nonconfrontational approach is really useful for dealing with these issues, and discuss how his method can be improved.
