Force and mind are opposites; morality ends where a gun begins.

It's not that I don't suffer, it's that I know the unimportance of suffering. I know that pain is to be fought and thrown aside, not to be accepted as part of one's soul and as a permanent scar across one's view of existence.

The alleged short-cut to knowledge, which is faith, is only a short-circuit destroying the mind

The fact that a man has no claim on others ... does not preclude or prohibit good will among men and does not make it immoral to offer or to accept voluntary, non-sacrificial assistance.

The government's only proper job is to protect individual rights against violence by force or fraud ... to protect men from foreign invaders ... to settle disputes among men according to objective laws ... The greatness of the Founding Fathers was how well they understood this issue and how close some of them came to understanding it perfectly.

Why had we let it go? Why had we both been condemned...to an exile among dreary strangers who had made us give up all desire for rest, for friendship, for the sound of human voices? Could I now reclaim a single hour spent talking to my brother, Philip, and give it to Ken Daggart? Who made it our duty to accept, as the only reward for our work, the gray torture of pretending love for those who roused nothing but contempt?

Happiness is not to be achieved at the command of emotional whims.
