My heroes have always been truth-tellers. The dissidents, the heretics, the whistle blowers, and the prophets. In their own time, most often they are marginalized, ridiculed, even imprisoned and worse, for challenging the sacred myths of those in power. Often it is not until much later, long after their own deaths in many cases, that history shows they were right to speak out. They told the truth and they did the world a good service.
