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 bells tolls; it tolls for thee.
John DonneMy face in thine eye, thine in mine appears, And true plain hearts do in the faces rest; Where can we find two better hemispheres, Without sharp north, without declining west? Whatever dies, was not mix'd equally; If our two loves be one, or, thou and I Love so alike, that none do slacken, none can die.
John Donne
