    Sir Arthur Conan Doyle (1859–1930)

    I could not undertake to form a nucleus of an institution for the development of infant minds, where none already existed. It would be too cruel.
    Henry David Thoreau (1817–1862)

    You know that the nucleus of a time is not
    The poet but the poem, the growth of the mind
    Of the world, the heroic effort to live expressed
    As victory. The poet does not speak in ruins
    Nor stand there making orotund consolations.
    He shares the confusions of intelligence.
    Wallace Stevens (1879–1955)
