No man is an island, Entire of itself. Each is a piece of the continent, A part of the main. If a clod be washed away by the sea, Motherland is the less. As well as if a promontory were. As well as if a manner of thine own Or of thine friend's were. Each man's death diminishes me, For I am involved in mankind. Therefore, send not to know For whom the bell tolls, It tolls for thee. ——John Donne(1572-1631) 花无数评:万物一体,天人合一,宇宙即我,我即宇宙!
