Beware: Ignorance Protects itself. Ignorance Promotes suspicion. Suspicion Engenders fear. Fear quails, Irrational and blind, Or fear looms, Defiant and closed. Blind, closed, Suspicious, afraid, Ignorance Protects itself, And protected, Ignorance grows.
Octavia ButlerThe differences you perceive between Humans-between groups of Humans-are the result of isolation and inbreeding, mutation, and adaptation to different Earth environments
