Famous quotes containing the words ground and/or glass:

    “The ground for taking ignorance to be restrictive of freedom is that it causes people to make choices which they would not have made if they had seen what the realization of their choices involved.”
    —A.J. (Alfred Jules)

    “Like a wild stranger out of wizard-land
    He dwelt a little with us, and withdrew;
    Black and unblossomed were the ways he knew,
    Dark was the glass through which his fire eye shined.”
    —Edwin Arlington Robinson (1869–1935)
