What he wants is my companionship. Having great wealth sometimes makes people lonely! A cultivated woman, a woman of intelligence and breeding, can enrich a man’s life – immeasurably! I have those things to offer, and this doesn’t take them away. Physical beauty is passing. A transitory possession. But beauty of the mind and richness of the spirit and tenderness of the heart – and I have all of those things – aren’t taken away, but grow! Increase with the years! How strange that I should be called a destitute woman! When I have all of these treasures locked in my heart. I think of myself as a very, very rich woman! But I have been foolish – casting my pearls before swine!
– Tennessee Williams
A Streetcar Named Desire, Scene 10. Blanche explains to Stanley what her old college boyfriend Shep Huntleigh wants from her and what she has to offer him in return. She tries to convince Stanley that there is more to a woman than physical beauty and appearance. Blanche may be a fading beauty who is financially impoverished, but in her fantasy world she believes that the married Texas oil millionaire will want her for her beautiful spirit and mind. Her speech is a deluded hymn to herself, where in a metaphor she compares such riches she has to offer to treasures. When she uses the animal metaphor "casting my pearls before swine" she admits to foolishly giving what she has to offer to those who don’t appreciate it. Her use of "pearls" and "swine" link to the theme of social class and Blanche’s social snobbery. Stanley takes the animal imagery as a personal insult.
