One can be a partisan of the left or right and still adhere to this proverb. Do not be deluded by fanatics, thugs, and rascals just because they claim to be your ally.
“When someone is honestly 55 percent right, that’s very good and there’s no use wrangling. And if someone is 60 percent right, it’s wonderful, it’s great luck, and let him thank God.
“But what’s to be said about 75 percent right? Wise people say this is suspicious. Well, and what about 100 percent right? Whoever says he’s 100 percent right is a fanatic, a thug, and the worst kind of rascal.”
— An old Jew of Galicia (Quoted by Czelaw Milosz)
