"The man who does not read good books has no advantage over the man who
cannot read them." -Mark Twain  (1835-1910)

"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 weep down the
mightiest walls of oppression and injustice." - Robert F Kennedy
