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 weoo as if a promontory ere,
as well as if a manor of thy friends or of thine own were
any man's death diminishes me, because I am involved in mankind
and therfore never send to know for whom te bell tolls
it tolls for thee.

(John Donne, 1624)
