To Change Opinion
No one who, against other people's opinion, has predicted the outcome of something exactly as it then turns out, should think that those who opposed him, once they see what has happenned, will say he was right, and say he was wiser or more understanding than they were. No, they will deny the fact, or the prediction, or else they will allege that the circumstances differ somehow. Or they will find some other way to convince themselves and others that their opinion was correct, and the opposite opinion mistaken.
Giacomo Leopardi, in 'Thoughts'
