Quote #7
LADY BRITOMART: What do you mean by the horrible truth, pray?
CUSINS: That she was enormously rich; that her grandfather was an earl; that her father was the Prince of Darkness—
UNDERSHAFT: Chut!
CUSINS:—and that I was only an adventurer trying to catch a rich wife, then I stooped to deceive her about my birth. (3.247-250)
We are learning a deep, dark secret about Dolly here: When he first met Barbara at the Army, he didn't know she was upper class and rich, so he actually thought that he would be a catch for her. When he found out the truth, he realized that that he was the potential opportunist here.
Quote #8
Don't listen to his metaphysics, Barbara. The place is driven by the most rascally part of society, the money hunters, the pleasure hunters, the military promotion hunters; and he is their slave. (3.301)
Dolly is giving his opinion of Undershaft's place in society (and his factory's). However, he actually reverses the general impression that Undershaft is Mr. Powerful, envisioning him as a "slave" to this "rascally" element.
Quote #9
There is no wicked side: life is all one. And I never wanted to shirk my share in whatever evil must be endured, whether it be sin or suffering. I wish I could cure you of middle-class ideas, Dolly. (3.418)
Barbara has always maintained that there's no such thing as "good" and "bad" men, since they're all children of God, and her points here agree with that general view point. Apparently, in her view, thinking that there is a "wicked" side of life that can be kept separate from the rest of life is "middle class." Hmm, maybe she is a bit of a snob after all?
