Remember that rights are moral principles which define and protect a man's freedom of action, but impose no obligations on other men. - Ayn Rand

There is no such thing as duty. If you know that a thing is right, you want to do it. If you don't want to do it—it isn't right. If it's right and you don't want to do it—you don't know what right is and you're not a man.

"There are no evil thoughts, Mr. Rearden," Francisco said softly, "except one: the refusal to think."

Every man builds his world in his own image; he has the power to choose, but no power to escape the necessity of choice. If he abdicates his power, he abdicates the status of man, and the grinding chaos of the irrational is what he achieves as his sphere of existence — by his own choice.
