Famous quotes containing the words elevation and/or model:
“Give the slave the least elevation of religious sentiment, and he is not slave: you are the slave: he not only in his humility feels his superiority, feels that much deplored condition of his to be a fading trifle, but he makes you feel it too. He is the master.”
—Ralph Waldo Emerson (1803–1882)
“... if we look around us in social life and note down who are the faithful wives, the most patient and careful mothers, the most exemplary housekeepers, the model sisters, the wisest philanthropists, and the women of the most social influence, we will have to admit that most frequently they are women of cultivated minds, without which even warm hearts and good intentions are but partial influences.”
—Mrs. H. O. Ward (1824–1899)
