Famous quotes containing the word infinity:

    As we begin to comprehend that the earth itself is a kind of manned spaceship hurtling through the infinity of space—it will seem increasingly absurd that we have not better organized the life of the human family.
    Hubert H. Humphrey (1911–1978)

    The poetic notion of infinity is far greater than that which is sponsored by any creed.
    Joseph Brodsky (b. 1940)

    We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometime stop that motion.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
