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 rules of the mystics. "Renaissance" means the "rebirth". Few people today will care to remind you that it was a rebirth of reason - of man's mind.
Ayn RandIf [people] place such things as friendship and family ties above their own productive work, yes, then they are immoral. Friendship, family life and human relationships are not primary in a man's life. A man who places others first, above his own creative work, is an emotional parasite.
Ayn RandThe greatest threat to mankind and civilization is the spread of the totalitarian philosophy. Its best ally is not the devotion of its followers but the confusion of its enemies. To fight it, we must understand it.
