Today marks the 50th anniversary of Senator Robert F. Kennedy's "Ripple of Hope" speech. The speech was delivered at the University of Cape Town on June 6, 1966, during the height of apartheid. Many historians believe the "Ripple of Hope" address was the greatest speech of his life.
My favorite snippet of the speech is uniquely uplifting: "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 which can sweep down the mightiest walls of oppression and resistance. "
