Life is filled with imaginary evils. A woman worries all her life that her children may be harmed. She suffers their imagined deaths a thousand times while they play ball, swing on swings and blow out birthday candles. A man fears that someone will harm him. He faces teh imaginary intruder every time his family takes a walk at night, he has some moments to himself or he attends a crowded festival of celebration. Better to worry and fear when the actual moment of suffering arises than to suffer an imagined misery all of one’s days while surrounded by joy.
