People say it would be terrible if we made all girls pretty. I think it would be great. - James Watson

Watson: But legalities aside, I think we must reevaluate our basic assumptions about the meaning of life. Perhaps, as my former colleague Francis Crick suggested, no one should be thought alive until about three days after birth.

Moving forward will not be for the faint of heart. But if the next century witnesses failure, let it be because our science is not yet up to the job, not because we don't have the courage to make less random the sometimes most unfair courses of human evolution.

The reality is that the idea of improving on the genes that nature has given us alarms people. When discussing our genes, we seem ready to commit what philosophers call the naturalistic fallacy, assuming that the way nature intended it is best. By centrally heating our homes and taking antibiotics when we have an infection, we carefully steer clear of the fallacy in our daily lives, but mentions of genetic improvement have us rushing to run the “nature knows best” flag up the mast. For this reason, I think that the acceptance of genetic enhancement will most likely come about through efforts to prevent disease.
