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 from Meditation XVII
