The fact is, that civilization requires slaves. The Greeks were quite right there. Unless there are slaves to do the ugly, horrible, uninteresting work, culture and contemplation become impossible.
Human slavery is wrong, insecure, and demoralizing.
On mechanical slavery, on the slavery of the machine, the future of the world depends. And the Warder is Despair. But some of us are looking at the stars. As long as mankind is trapped on Earth, we are like rats in a cage, with the potential for much anguish and despair. No wonder then that so many take the nihilistic path to self-destruction, or embrace hedonism to dispel their suffering.
