In Nightingale and the Rose, the student says that he loves that girl, but he doesn’t take any action. After he was rejected by the girl, with the red rose exchanged with the life of the nightingale in his hand, he, however, does not cherish this hard-won rose, instead, he drops it. From this, we can see that he doesn’t understand love and either does he deserves it. “He” is a representative of the so-called “artist” in Wilde’s generation, speaking art yet without any knowledge about it. As to the daughter of the professor, she loves high position and great wealth more than the bloody rose exchanged with life, which shows her vulgar values. As the daughter of a professor, she has no idea about the true value of that rose. It also reflects the author’s sarcasm to society. Fourth, other characters.
