Diodotus son of Eucrates:
"I think the two things most opposed to good counsel are haste and passion; haste usually goes hand in hand with folly, passion with coarseness and narrowness of mind. As for the argument that speech ought not be the exponent of action, the man who uses it must be either senseless or personally interested: senseless if he believes it possible to deal with the uncertain future through any other medium; interested if wishing to carry a disgraceful measure and doubting his ability to speak well in a bad cause, he thinks to frighten opponents and hears by well-aimed calumny... The good citizen ought to triumph not by frightening his opponents but by beating them fairly in argument." (Thucydides, War, 3.42.1-2, 5)
I thought of three things when I read this quote: 1) myself and other supporters of the Iraq War during late 2002/early 2003 telling those on the fence the world was going to end if we didn't act, and 2) Hank Paulson breathlessly going from Sunday talk show to Sunday talk show during prior to the big bailout telling those on the fence that the world was going to end if we didn't act, and 3) LBJ's "daisy" ad which assisted him in achieving a landslide victory over Barry Goldwater in the 1964 presidential election, which showed a picture of the world ending if viewers didn't act. All of these were cases of haste and passion being the enemies of conservatism. The implication? By definition, it is occasionally better not to triumph. Why? Because good is better than triumph.
