The ever quickening advances of science made possible by the success of the Human Genome Project will also soon let us see the essences of mental disease. Only after we understand them at the genetic level can we rationally seek out appropriate therapies for such illnesses as schizophrenia and bipolar disease.

A clone of Einstein wouldn't be stupid, but he wouldn't necessarily be any genius, either.
