Famous quotes containing the word members:
“This Administration has declared unconditional war on poverty and I have come here this morning to ask all of you to enlist as volunteers. Members of all parties are welcome to our tent. Members of all races ought to be there. Members of all religions should come and help us now to strike the hammer of truth against the anvil of public opinion again and again until the ears of this Nation are open, until the hearts of this Nation are touched, and until the conscience of America is awakened.”
—Lyndon Baines Johnson (1908–1973)
“[T]here is no breaking out of the intentional vocabulary by explaining its members in other terms.”
—Willard Van Orman Quine (b. 1908)
“... the theatre demanded of its members stamina, good digestion, the ability to adjust, and a strong sense of humor. There was no discomfort an actor didn’t learn to endure. To survive, we had to be horses and we were.”
—Helen Hayes (1900–1993)
