Famous quotes containing the words ground and/or glass:

    A new word is like a fresh seed sown on the ground of the discussion.
    Ludwig Wittgenstein (1889–1951)

    Our ideal ... must be a language as clear as glass—the person looking out of the window knows there is glass there, but he is not concerned with it; what concerns him is what comes through from the other side.
    Elizabeth Bowen (1899–1973)
