" When apparent stability disintegrates,
As it must--
God is Change--
People tend to give in
To fear and depression,
To need and greed.
When no influence is strong enough
To unify people
They divide.
They struggle,
One against one,
Group against group,
For survival, position, power.
They remember old hates and generate new ones,
The create chaos and nurture it.
They kill and kill and kill,
Until they are exhausted and destroyed,
Until they are conquered by outside forces,
Or until one of them becomes
A leader
Most will follow,
Or a tyrant
Most fear. "

― Octavia E. Butler , Parable of the Sower (Earthseed, #1)
