Cecily and Gwendolen are dissimilar in some aspects of their personalities and backgrounds. Gwendolen, on one hand, is confident, worldly, and at home in the big city of London. While her mother has taught her to be shortsighted like the lorgnette through which Gwendolen peers at the world, she has also brought her daughter up in a traditional family, the only such family in the entire play. On the other hand, Cecily is introduced in a garden setting, the child of a more sheltered, natural, and less-sophisticated environment. She has no mother figure other than the grim Miss Prism, and she has a guardian instead of a parent.
Gwendolen provides Wilde with the opportunity to discuss marriage, courtship and the absurdities of life. Her pronouncements on trivialities and her total contradictions of what she said two lines earlier make her the perfect instrument for Wilde to provide humor and to comment on inane Victorian attitudes. Cecily provides Wilde with an opportunity to discuss dull and boring education, Victorian values, money and security, and the repression of passion. More sheltered than Gwendolen, Cecily is still expected to learn her boring lessons and make a good marriage.
