"It is from the 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 a tiny ripple of hope, and crossing each other from a million different centres of energy and daring, those ripples build a current which can sweep down the mightiest walls of oppression or resistance." -- Senator Robert Kennedy
(And may I add, Senator Kennedy would have been exceedingly proud of the man his son, Robert Kennedy Jr. has become.)
