for whom the bell tolls

The phrase "for whom the bell tolls" is derived from the famous meditation by John Donne, which states "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." This phrase signifies that the death of any person affects all of humanity. It emphasizes the interconnectedness and shared fate of all human beings.
