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 friends 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.
by
John Donne
