Sometimes, what is possibly true is more important than what is true.

Scenario: You are walking along on a busy city sidewalk, and you hear someone close by shout, "He's got a gun!". Do you ignore the warning as impossible? Do you stop and look around to see whether it is true? No, you will immediately duck or run for cover behind anything that might stop a bullet! This page figuratively shouts, "He's got a gun!", and then invites you to act, not on a fact, but on a possibility.
