Dignity is as essential to human life as water, food, and oxygen. The stubborn retention of it, even in the face of extreme physical hardship, can hold a man’s soul in his body long past the point at which the body should have surrendered it. The loss of it can carry a man off as surely as thirst, hunger, exposure, and asphyxiation, and with greater cruelty. In places like Kwajalein, degradation could be as lethal as a bullet.
