"Atlas Shrugged"--by Ayn rand

v The Duty of thinkers is not to explain, but to demonstrate that nothing can be explained.

v The purpose of philosophy is not to seek knowledge, but to prove that knowledge is impossible to man.

v Happiness is a delusion of those whose emotions are superficial.

v “Contradictions do not exist. Whenever you think that you are facing a contradiction, check your  premises. You will find that one of them is wrong.”

v  “If you tell a beautiful woman that she is beautiful, what have you given her? It's no more than a fact and it has cost you nothing. But if you tell an ugly woman that she is beautiful, you offer her the great homage of corrupting the concept of beauty. To love a woman for her virtues is meaningless. She's earned it, it's a payment, not a gift. But to love her for her vices is a real gift, unearned and undeserved. To love her for her vices is to defile all virtue for her sake - and that is a real tribute of love, because you sacrifice your conscience, your reason, your integrity and your invaluable self-esteem.”

v “If one's actions are honest, one does not need the predated confidence of others.”

v “Don't think of them now. Never think of pain or danger or enemies a moment longer than is necessary to fight them. You're here. It's our time and our life, not theirs. Don't struggle not to be happy. You are."

v I am, therefore I'll think”

v “Happiness is a state of non-contradictory joy--a joy without penalty or guilt, a joy that does not clash with any of your values and does not work for your own destruction, not the joy of escaping from your mind, but of using your mind's fullest power, not the joy of faking reality, but of achieving values that are real, not the joy of a drunkard, but of a producer.”

v “There are no evil thoughts except one; the refusal to think.”

v “Any work is creative work if done by a thinking mind.”

v “He never felt lonliness except when he was happy.”

v In this world, either you're virtuous or you enjoy yourself. Not both...Not both.”

v “Rationality is the recognition of the fact that nothing can alter the truth and nothing can take precedence over that act of perceiving it.”

v “ Never think of pain or danger or enemies a moment longer than is necessary to fight them.”

v “There is no necessity for pain-why, then, is the worst pain reserved for those who will not accept its necessity?”

v “The sight of an achievement was the greatest gift a human being could offer to others.”

v “I think it's a sin to sit down and let your life go without making a try for it.”

v “Reason is not automatic. Those who deny it cannot be conquered by it”

v “Man has the power to act as his own destroyer and that is he has acted through most of history.”

v “Sacrifice is the surrender of that which you value in favor of which you dont”

v “To me there's only one form of human depravity-the man without a purpose.”

v “Money will not buy intelligence for the fool, or admiration for the coward, or respect for the incompetent.”
