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.
-- Robert F. Kennedy, South Africa, 1966
