Is it right to use biomedical technologies to make us better than well or even perhaps better than human? Should we view our biology as fixed or should we try to improve on it? College students are already taking cognitive enhancement drugs. The U.S. army is already working to develop drugs and technologies to produce "super soldiers." Scientists already know how to use genetic engineering techniques to enhance the strength and memories of mice and the application of such technologies to humans is on the horizon. In Better Than Human, philosopher-bioethicist Allen Buchanan grapples with the ethical dilemmas of the biomedical enhancement revolution. Biomedical enhancements can make us smarter, have better memories, be stronger, quicker, have more stamina, live much longer, avoid the frailties of aging, and enjoy richer emotional lives. In spite of the benefits that biomedical enhancements may bring, many people instinctively reject them. Some worry that we will lose something important-our appreciation for what we have or what makes human beings distinctively valuable. Others assume that biomedical enhancements will only be available to the rich, with the result that social inequalities will worsen. Buchanan shows that the debate over enhancement has been distorted by false assumptions and misleading rhetoric. To think clearly about enhancement, we have to acknowledge that human nature is a mixed bag and that our species has many "design flaws." We should be open be open to the possibility of becoming better than human, while never underestimating the risks that our attempts to improve may back-fire.

Desiring the Good defends a novel and distinctive approach in ethics that is inspired by ancient philosophy. Ethics, according to this approach, starts from one question and its most immediate answer: "what is the good for human beings?"--"a well-going human life." Ethics thus conceived is broader than moral philosophy. It includes a range of topics in psychology and metaphysics. Plato's Philebus is the ancestor of this approach. Its first premise, defended in Book I of Aristotle's Nicomachean Ethics, is that the final agential good is the good human life. Though Aristotle introduces this premise while analyzing human activities, it is absent from approaches in the theory of action that self-identify as Aristotelian. This absence, Vogt argues, is a deep and far-reaching mistake, one that can be traced back to Elizabeth Anscombe's influential proposals. And yet, the book is Anscombian in spirit. It engages with ancient texts in order to contribute to philosophy today, and it takes questions about the human mind to be prior to, and relevant to, substantive normative matters. In this spirit, Desiring the Good puts forward a new version of the Guise of the Good, namely that desire to have one's life go well shapes and sustains mid- and small-scale motivations. A theory of good human lives, it is argued, must make room for a plurality of good lives. Along these lines, the book lays out a non-relativist version of Protagoras's Measure Doctrine and defends a new kind of realism about good human lives.
