Because it's election season and we're all beholden to polls, we should recall Harry S. Truman's great counterfactual put-down of polls (which I came across today):
"I wonder how far Moses would have
gone if he'd taken a poll in Egypt? What would Jesus Christ have
preached if he'd taken a poll in Israel? Where would the Reformation
have gone if Martin Luther had taken a poll? It isn't polls or public
opinion of the moment that counts. It is right and wrong and
leadership--men with fortitude, honesty and a belief in the right that
makes epochs in the history of the world."
(From Truman's diary, 1954, Post-Presidential Papers).
