In his new book, The Undiscovered Mind: How the Human Brain
Defies Replications, Medication and Explanation (New York:
The Free Press, 1999), John Horgan writes
"The Princeton geneticist Lee Silver cranked up the rhetoric
even higher in his 1997 book, Remaking Eden. Silver prophesied
that genetic engineering might one day divide humanity into
separate species: the Genrich class, which can afford genetic
engineering, and the Natural class, which cannot. The Genrich
class will be supremely talented intellectually and athletically,
free of physical and mental illness, and possibly even immortal.
"These utopian (dystopian?) predictions are ludicrous—and,
from leading geneticists, irresponsible—given the track
of behavioral genetics thus far" (p. 161).
