During McCarthyism, teachers feared for their jobs if they belonged to a left-wing group. Today teachers fear for their jobs if they hug a crying child. As in all moral panics, an accusation is enough to destroy a person's life. Hysteria trumps evidence.

The second-sweetest set of three words in English is 'I don't know.'

Science is a form of arrogance control.

Even irrefutable evidence is rarely enough to pierce the mental armor of self-justification.

The individualism of American life, to our glory and despair, creates anger and encourages its release; for when everything is possible, limitations are irksome. When the desires of the self come first, the needs of others are annoying. When we think we deserve it all, reaping only a portion can enrage.

Rebels and dissidents challenge the complacent belief in a just world, and, as the theory would predict, they are usually denigrated for their efforts. While they are alive, they may be called 'cantankerous,' 'crazy,' 'hysterical,' 'uppity,' or 'duped.' Dead, some of them become saints and heroes, the sterling characters of history. It's a matter of proportion. One angry rebel is crazy, three is a conspiracy, 50 is a movement.

History is written by the victors, but it's victims who write the memoirs.
