Truth is defined by those with the Power. Power is attained by those with the resources to acquire it. The resources are typically 'taken' from the weak or ignorant. The weak and ignorant are doomed to speak of injustice and definition of "Truth". But the pendulum occasionally swings in the other direction. When the weak become strong by banding together under a common cause and then have the Power to institute a new "Truth".
