“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)
“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)
