Famous quotes containing the word conclusion:
“I’ve heard the wolves scuffle, and said: So this
Is man; so what better conclusion is there
The day will not follow night, and the heart
Of man has a little dignity, but less patience
Than a wolf’s....”
—Allen Tate (1899–1979)
“So this
Is man; so—what better conclusion is there—
The day will not follow night, and the heart
Of man has a little dignity, but less patience
Than a wolf’s,”
—Allen Tate (1899–1979)
“I have come to the conclusion that the closer people are to what may be called the front lines of government ... the easier it is to see the immediate underbrush, the individual tree trunks of the moment, and to forget the nobility the usefulness and the wide extent of the forest itself.... They forget that politics after all is only an instrument through which to achieve Government.”
—Franklin D. Roosevelt (1882–1945)
