“Brave New Genetics” is not just a metaphor for Aldous Huxley’s book published in the 1930s. Huxley’s fantastic world of frozen embryos, prenatal tests, and genetic choices is our present. The new genetics is a world that is both marvelous and frightening. This book deals with the tension between fascination and repugnance provoked by genetics: sometimes it is a wonderful world that opens up, sometimes it is the ghost of eugenics and oppression.
