Famous quotes containing the word companions:

    Dear fellow-artist, why so free
    With every sort of company,
    With every Jack and Jill?
    Choose your companions from the best;
    Who draws a bucket with the rest
    Soon topples down the hill.
    William Butler Yeats (1865–1939)

    Yet the companions of the Muses
    will keep their collective nose in my books
    And weary with historical data, they will turn to my dance tune.
    Ezra Pound (1885–1972)

    There was never a man born so wise or good, but one or more companions came into the world with him, who delight in his faculty, and report it. I cannot see without awe, that no man thinks alone and no man acts alone, but the divine assessors who came up with him into life,—now under one disguise, now under another,—like a police in citizen’s clothes, walk with him, step for step, through all kingdoms of time.
    Ralph Waldo Emerson (1803–1882)
