G.K. CHESTERTON on Humility.

"What we suffer from today is humility in the wrong place.
Modesty has moved from the organ of ambition. Modesty
has settled upon the organ of conviction; where it was
never meant to be. A man was meant to be doubtful about
himself, but undoubting about the truth; this has been
exactly reversed. Nowadays the part of a man that a man
does assert is exactly the part he ought not to assert -
himself."

Quoted from the chapter called "The Suicide of Thought"
in his book "Orthodoxy", published in 1908.
