To know how little one knows is to have genuine knowledge.
Not to know how little one knows is to be deluded.
Only he who knows when he is deluded can free himself from such delusions.
The intelligent man is noe deluded, because he knows and accepts his ignorance as ignorance, and thereby has genuine knowledge.
Tao Teh King, LXXI, oversatt av Archie J. Bahm
