Famous quotes containing the words erroneous and/or recommended:

    Men have an extraordinarily erroneous opinion of their position in nature; and the error is ineradicable.
    W. Somerset Maugham (1874–1966)

    I am like a doctor. I have written a prescription to help the patient. If the patient doesn’t want all the pills I’ve recommended that’s up to him. But I must warn that next time I will have to come as a surgeon with a knife.
    —Javier Pérez De Cuéllar (b. 1920)
