The leader must have the courage to go where nobody dared to venture before in the world of the minds and spirits of men.
He must question what was always assumed to be correct. He must challenge beliefs handed down from generation to generation and accepted as being real. He must stand for the truth no matter what the cost is.
He must support the oppressed, the weak, and the deprived and stand up to the raw power of the oppressors, no matter who they may be. All these things help the leader to inspire trust, the very foundation of leadership.
