Martin Luther King Jr. said this quote
“ I accept this award today with an abiding faith in America and an audacious faith in the future of mankind. I refuse to accept despair as the final response to the ambiguities of history. I refuse to accept the idea that the isness of man's present nature makes him morally incapable of reaching up for the eternal oughtness that forever confronts him. I refuse to accept the idea that man is mere flotsom and jetsom in the river of life, unable to influence the unfolding events which surround him. I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. ”
