Ms Neiman thinks that people yearn for a sense of moral purpose.
In a world preoccupied with consumerism and petty self-interest, that gives life dignity.
People want to determine how the world works, not always to be determined by it.
It means that people's behavior should be shaped not by who is most powerful, or by who stands to lose or gain, but by what is right despite the costs.
Moral sensibility is why people will suffer for their beliefs, and why acts of principled self-sacrifice are so powerful.
People can distinguish what is and what ought to be.
Torture was once common in Europe's market squares.
It is now unacceptable even when the world's most powerful nation wears the interrogator's mask.
Race was once a bar to the clubs and drawing-rooms of respectable society.
Now a black man is in the White House.
