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 Butler (1947-2006) American writer

Parable of the Talents, ch. 12, epigram (1998)
