The creator's concern is the conquest of nature. The parasite's concern is the conquest of men.
Ayn RandThe truly and deliberately evil men are a very small minority; it is the appeaser who unleashes them on mankind; it is the appeaser's intellectual abdication that invites them to take over. When a culture's dominant trend is geared to irrationality, the thugs win over the appeasers. When intellectual leaders fail to foster the best in the mixed, unformed, vacillating character of people at large, the thugs are sure to bring out the worst. When the ablest men turn into cowards, the average men turn into brutes.
Ayn RandThe Middle Ages were an era of mysticism, ruled by blind faith and blind obedience to the dogma that faith is superior to reason. The Renaissance was specifically the rebirth of reason, the liberation of man's mind, the triumph of rationality over mysticism - a faltering, incomplete, but impassioned triumph that led to the birth of science, of individualism, of freedom.
