Peace and piece
Mr. Praed says he knows nothing of Mrs. Warren's profession, but his behavior indicates otherwise. However, he does not seem bothered by the fact that Mrs. Warren is a "working woman." He is nonjudgmental. As an architect, he is not of the upper class, but of the middle class.
Mr. Crofts, however, is directly involved in Mrs. Warren's profession by the fact that he owns brothels. His moral sensibility is much worse than Mr. Praed's as a result. He is a member of the upper class and feels very entitled to his wealth--also lowering his moral sensibility.
