This is a very good book, but not because it brings good news. John H. Evans, a sociologist at the University of California, San Diego, carefully documents how religious voices have been marginalized in the public debates over the human genome project. Evans documents as well how the absence of religious voices has made the public debates less rich. Playing God? should be read by anyone interested in the discussions of the human genome project and, more generally, in how religious voices and communities might participate in public debate, and what is likely to happen if they do not.

Evans is interested in what groups or professions control particular  social domains. In brief, who is in charge of what? Evans's narrative begins in the 1970s, when the possibilities of the discoveries in genetics were only beginning to dawn upon scientists. He relates how scientists, who wished to be in charge, reported what they thought should be done and how they were chastised by theologians because of what the theologians perceived as hubris. As a consequence, scientists lost control of the public discussion of the human genome project.

Faced with the possibility that governmental regulatory bodies would constrain what scientists might do, scientists suggested that there should be governmental advisory bodies, which would not have the regulatory powers the scientists feared. Evans describes how, with the help of the bioethicists who were placed on these advisory commissions, scientists have regained control of the conversation surrounding the human genome project. The bioethicists and scientists use what Evans calls "formal rationality." They do not honor requests that substantive matters be discussed. As a result, there is no significant discussion of the purposes of the scientific research into the human genome--research often paid for, I might add, by taxpayer dollars. Legislators fear becoming embroiled in the issues and also worry that they do not have the expertise to engage in substantive discussion. So there is no further discussion.
