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.
John Donne
(1572-1644)
