Reason is no longer an agency that directs other traditions, it is a tradition in its own right with as much (or as little) claim to the centre of the stage as any other tradition. Being a tradition it is neither good nor bad, it simply is. The same applies to all traditions – they are neither good nor bad, they simply are. They become good or bad (rational/irrational; pious/impious; advanced/'primitive'; humanitarian/vicious; etc.) only when looked at from the point of view of some other tradition.
