The authors, Dan Brock, Allen Buchanan, Norman Daniels, and Daniel Wikler, repeatedly emphasize their opinion that advances in genetic technology force upon us entirely new ethical questions which previous moral theories lack the resources to resolve.2 The claims that new scientific discoveries render previous moral theories obsolete should be regarded with suspicion. The reader’s suspicion should be further aroused when she notes another feature of the authors’ theorizing that neatly fits the claim that we stand at the dawn of a new world of ethical theorizing. The authors’ discussion from start to finish stays at a middle level.
