I think your question is nearly impossible for me to answer, but the first line to the book I am reading now, The Decameron by Giovanni Boccaccio, should make the list:
"It is inherently human to show pity to those who are afflicted; it is a quality that becomes any person, but most particularly is it required of those who have stood in need of consolation and have obtained it from others; now if ever there was a man who craved pity or valued it or rejoiced in it, that man was I."
