Gwendolen and Celicy care less about who they are, what their true names are, they forgive them, and have a happy ending. This change shows that their ideas about marriage have switched from naive to mature. They no longer depend on imagination but base more on true love.
The two young men also experience attitude changes. They live in a two-identity life by the mean of lying. Jack creates a brother called "Ernest", in order to go to London to have fun, and Algernon images a friend named "Bunburry" to have excuses to visit "him" in the countryside. Jack tells Algernon his goal of going to the city is pursuing pleasure, "Oh, pleasure, pleasure! What else should one bring one anywhere?" (1.308). In other words, love is a tool of entertainment for him. When Algernon talks about marriage, he says, "I really don't see anything romantic in proposing. It is very romantic to be in love. But there is nothing romantic about a definite proposal. Why, one may be accepted. One usually is, I believe. Then the excitement is all over. The very essence of romance is uncertainty. If ever I get married, I'll certainly try to forget the fact" (1.308). Their casual attitude of marriage is shown through their conversations. After they meet with their beloved girls, and then their lies are finally exposed, they decide to give up their unmindful attitude, try their best to persuade Gwendolen and Celily to stay with them. It distinctively contrasts with their attitude before, and conveys that it is important to be earnest in marriage.
Moreover, when Lady Bracknell knows that her daughter is going to marry with Jack, she requires to examine every aspect of him, includes whether his income is high, whether he owns a house and whether he smokes. "I confess I feel some what bewildered by what you have just told me. To be born, or at nay rate bred, in a hand-bag, whether it had handles or not, seems to me to display a contempt for the ordinary decencies of family life that reminds one of the worst excesses of the French revolution" (1.
