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 RandCollectivism holds that the individual has no rights, that his life and work belong to the group (to "society," to the tribe, the state, the nation) and that the group may sacrifice him at its own whim to its own interests. The only way to implement a doctrine of that kind is by means of brute force - and statism has always been the poltical corollary of collectivism.
Ayn RandI do not seek the good of others as a sanction for my right to exist, nor do I recognize the good of others as a justification for their seizure of my property or their destruction of my life.
Ayn RandI don't like people who speak or think in terms of gaining anybody's confidence. If one's actions are honest, one does not need the predated confidence of others, only their rational perception. The person who craves a moral blank check of that kind, has dishonest intentions, whether he admits it to himself or not.
