Human pride refuses to face the truth. (William Wilberforce, 18th-19th century English politician and philanthropist)
Wilberforce was a leader in the anti-slave trade in England; he also promoted a return to civility in the social life of his country. Perhaps it was in those long-lasting and bitter struggles that he discovered the great tragedy of pride. The proud and arrogant often cannot face the truth because it would require them to change their mistaken values.
Pride goes before destruction, a haughty spirit before a fall (Proverbs 16:18).
