Famous quotes containing the words elevation and/or model:

    All our lives we fought against exalting the individual, against the elevation of the single person, and long ago we were over and done with the business of a hero, and here it comes up again: the glorification of one personality. This is not good at all. I am just like everybody else.
    Vladimir Ilyich Lenin (1870–1924)

    For an artist to marry his model is as fatal as for a gourmet to marry his cook: the one gets no sittings, and the other gets no dinners.
    Oscar Wilde (1854–1900)
