With ongoing advances in reproductive technology and genetic engineering, man's ability to make himself what he pleases is increasingly within reach. The power to change human nature says nothing at all about whether we ought to change it. Both Aldous Huxley and C. S. Lewis made disturbing predictions about man's possible future. Both explored what might happen if technologies like genetic engineering and psychological conditioning were unwisely applied to mankind.
Society is structured into five classes.
On top are the Alphas, society's elite. They are the intellectuals, educators, and government officials. At bottom are the Epsilons. They handle society's most menial tasks. In the middle are the Betas, Gammas, and Deltas, each having responsibilities appropriate to their class.
