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
