No man is an island

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 any man­ner 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.

–John Donne
