论死亡(On Death)

　　according to cycle of life all things must die. and when some one dies, those who love him weep, and mourn his death. but when we weep at the death of someone we love, or at the realization that death will soon take him away, aren't we weeping at our own loss?

　　do we pity him because he is going to die, or do you feel sorry for yourself because you are going to lose him?
