In Western Civilization, the period ruled by mysticism is known as
the Dark Ages and the Middle Ages. I will assume that you know the
nature of that period and the state of human existence in those
ages. The Renaissance broke the rule of the mystics. "Renaissance"
means "rebirth." Few people today will care to remind you that it
was a rebirth of reason - of man's mind.
