Who casts not up his eye to the sun when it rises?
But who takes off his eye from a comet, when that breaks out?
who bends not his ear to any bell, which upon any occasion rings?
But who can remove it from that bell, which is passing a piece of himself out of this world?
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.
Del poeta británico John Donne in “Devotions Upon Emergent Occasions”.
