"This is an example of what I call "lifeboat questions"--ethical formulations such as"What should a man do if he and another man are in a lifeboat that can hold only one?" First, every code of ethics must be based on a metaphysics--on a view of the world in which man lives. But man does not live in a lifeboat--in a world in which he must kill innocent men to survive."

-Ayn Rand
