I find Frank Herbert's view of humanity, as in "God Emperor of Dune" very pessimistic around human nature, requiring a 3000 years tyrannical ruling to save humanity from its own destructive and short term thinking. Havent read Destination: Void but seems like Herbert didnt hold fond of humanity.
Most civilization is based on cowardice. It's so easy to civilize by teaching cowardice. You water down the standards which would lead to bravery. You restrain the will. You regulate the appetites. You fence in the horizons. You make a law for every movement. You deny the existence of chaos. You teach even the children to breathe slowly. You tame.
The Stolen Journals
and my favorite:
When I set out to lead humankind along my Golden Path, I promised them a lesson their bones would remember. I know a profound pattern which humans deny with their words even while their actions affirm it. They say they seek security and quiet, the condition they call peace. Even as they speak, they create the seeds of turmoil and violence. If they find their quiet security, they squirm in it. How boring they find it. Look at them now. Look at what they do while I record these words. Hah! I give them enduring eons of enforced tranquility which plods on and on despite their every effort to escape into chaos. Believe me, the memory of Leto's Peace shall abide with them forever. They will seed their quiet security thereafter only with extreme caution and steadfast preparation.
