No man, proclaimed Donne, is an island, and he was wrong. If we were not islands, we would be lost, drowned in each other's tragedies. We are insulated (a word that means, literally, remember, made into an island) from the tragedy of others, by our island nature. <...> We draw our lines around these moments of pain, remain upon our islands, and they cannot hurt us. They are covered with a smooth, safe, nacreous layer to let them slip, pearllike, from our souls without real pain.
