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 DonneAnd now good morrow to our waking souls, Which watch not one another out of fear; For love, all love of other sights controls, And makes one little room, an everywhere. Let sea-discoverers to new worlds have gone, Let maps to other, worlds on worlds have shown, Let us possess one world, each hath one, and is one.
John Donne
