A chronic lack of pleasure, of any enjoyable, rewarding or stimulating experiences, produces a slow, gradual, day-by-day erosion of man's emotional vitality, which he may ignore or repress, but which is recorded by the relentless computer of his subconscious mechanism that registers an ebbing flow, then a trickle, then a few last drops of fuel--until the day when his inner motor stops and he wonders desperately why he has no desire to go on, unable to find any definable cause of his hopeless, chronic sense of exhaustion.
Ayn RandTo know one's own desires, their meaning and their costs requires the highest human virtue: rationality.
Ayn RandYou have chosen to risk your lives for the defense of this country. I will not insult you by saying that you are dedicated to selfless service--it is not a virtue in my morality. In my morality, the defense of one's country means that a man is personally unwilling to live as the conquered slave of any enemy, foreign or domestic. This is an enormous virtue.
