Perchance he for whom this bell tolls may be so ill as that he knows not it tolls for him. And perchance I may think myself so much better than I am, as that they who are about me, and see my state, may have caused it to toll for me, and I know not that. The church is catholic, universal, so are all her actions; all that she does, belongs to all.
…
No man is an island, entire of itself; every man is a piece of the continent, a part of the main; if a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend’s or of thine own were; any man’s death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee.
