Famous quotes containing the words and vii*, mark and/or vii:

    Me, what’s that after all? An arbitrary limitation of being bounded by the people before and after and on either side. Where they leave off, I begin, and vice versa.
    Russell Hoban (b. 1925)

    The burning of rebellious thoughts in the little breast, of internal hatred and opposition, could not long go on without slight whiffs of external smoke, such as mark the course of subterranean fire.
    Harriet Beecher Stowe (1811–1896)

    I cannot be indifferent to the assassination of a member of my profession, We should be obliged to shut up business if we, the Kings, were to consider the assassination of Kings as of no consequence at all.
    —Edward VII (1841–1910)
