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 thy 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 (1572 – 1631), England
