Do not judge a man by where he stands, but how he reached there.
Get to know two things about a man. How he earns his money and how he spends it. You will then have the clue to his character. You will have a searchlight that shows up the inmost recesses of his soul. You know all you need to know about his standards, his motives, his driving desires, his real religion.

To stand by yourself - that was also part of dignity. That way, a person could get through a public flaying with dignity. Galileo. Luther. Even somebody who admitted his guilt and resisted the temptation to deny it. Something politicians couldn't do. Honesty, the courage for honesty. With others and yourself.
