Hijacking Words

John Piper (in Brothers, We Are Not Professionals) quotes G. K. Chesterton, who wrote in 1908,

What we suffer from today is humility in the wrong place. Modesty has moved from the organ of ambition. Modesty has settled on 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. The part he doubts is the part he ought not to doubt -- the Divine Reason. . . . We are on the road to producing a race of man too mentally modest to believe in the multiplication table.

G. K. Chesterton, Orthodoxy

For these reasons he foresaw the culture hijacking the word arrogance and using it to refer to conviction and the word humility to refer to uncertainty (Brothers p. 161).

Just look at the comments on any blog discussing the emerging/ent church. Is this true, or is this true?
