Humility in the wrong place
“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. . . .
We are on the road to producing a race of men too mentally modest to believe in the multiplication table.”
G. K. Chesterton, Orthodoxy (Garden City, 1959), pages 31-32.
