Famous quotes containing the words list of, list, divisions and/or population:
“Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.”
—Janet Frame (b. 1924)
“Lastly, his tomb
Shall list and founder in the troughs of grass
And none shall speak his name.”
—Karl Shapiro (b. 1913)
“Nothing does more to activate Christian divisions than talk about Christian unity.”
—Conor Cruise O’Brien (b. 1917)
“It was a time of madness, the sort of mad-hysteria that always presages war. There seems to be nothing left but war—when any population in any sort of a nation gets violently angry, civilization falls down and religion forsakes its hold on the consciences of human kind in such times of public madness.”
—Rebecca Latimer Felton (1835–1930)
