Famous quotes containing the word axis:

    I make this direct statement to the American people that there is far less chance of the United States getting into war, if we do all we can now to support the nations defending themselves against attack by the Axis than if we acquiesce in their defeat, submit tamely to an Axis victory, and wait our turn to be the object of attack in another war later on.
    Franklin D. Roosevelt (1882–1945)

    A book is not an autonomous entity: it is a relation, an axis of innumerable relations. One literature differs from another, be it earlier or later, not because of the texts but because of the way they are read: if I could read any page from the present time—this one, for instance—as it will be read in the year 2000, I would know what the literature of the year 2000 would be like.
    Jorge Luis Borges (1899–1986)

    He is the essence that inquires.
    He is the axis of the star;
    He is the sparkle of the spar;
    He is the heart of every creature;
    He is the meaning of each feature;
    And his mind is the sky,
    Than all it holds more deep, more high.
    Ralph Waldo Emerson (1803–1882)
