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)
“The striking point about our model family is not simply the compete-compete, consume-consume style of life it urges us to follow.... The striking point, in the face of all the propaganda, is how few Americans actually live this way.”
—Louise Kapp Howe (b. 1934)
