The inscription on the tombstone of assassinated U.S. Presidential hopeful and brother of assassinated President J F Kennedy, Senator Bobby Kennedy:

“It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal or acts to improve the lot of others or strikes out against injustice he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring those ripples build a current that can sweep down the mightiest walls of oppression and resistance.
