Famous quotes containing the words storage, access and/or methods:

    Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.
    Henry David Thoreau (1817–1862)

    Whilst the rights of all as persons are equal, in virtue of their access to reason, their rights in property are very unequal. One man owns his clothes, and another owns a country.
    Ralph Waldo Emerson (1803–1882)

    If men got pregnant, there would be safe, reliable methods of birth control. They’d be inexpensive, too.
    Anna Quindlen (b. 1952)
