The last sound on the worthless earthwill be two human beings trying to launch a homemade spaceship and already quarreling about where theyare going next.

-Faulkner,William Harrison
  Speech to UNESCO Commission, in the NewYork Times, 3 Oct.

I am a passenger on the spaceship, Earth.

-Fuller, R(ichard) Buckminster
  Operating Manual for Spaceship Earth, ch.1.

Space-ships and time machines are no escape from the human condition. Let Othello subject Desdemona to a lie-detector test; his jealousy will still blind him to the evidence. Let Oedipus triumph over gravity; he won't triumph over his fate.

-Koestler, Arthur
