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.
"The true essence of humankind is kindness. There are other qualities which come from education or knowledge, but it is essential, if one wishes to be a genuine human being and impart satisfying meaning to one's existence, to have a good heart."
