We humans do, when the cause is sufficient, spend our lives. We throw ourselves onto the grenade to save our buddies in the foxhole. We rise out of the trenches and charge the entreched enemy and die like maggots under a blowtorch. We strap bombs on our bodies and blow ourselves up in the midst of our enemies. We are, when the cause is sufficient, insane.
It was not right, thought Han Fei-tzu, for his wife to die before him: her ancestor-of-the-heart had outlived her husband. Besides, wives should live longer than husbands. Women were more complete inside themselves. They were also better at living in their children. They were never as solitary as a man alone.
