“ His voice had become firm. "But when you accept this degree of Doctor of Predictable Life-Lines, you will have forever severed yourself from normal humanity and the right to know your future. You are now declared a breed of man apart. You will never learn your own future. There is a reason for this, and the Galactic Federation is confident you will never cause trouble. No man who has ever stood in this room a Younger and walked out a doctor, has ever violated his oath. You have been investigated far more than you know. But all of you are human." ”
