Oscar Wilde made a significant impact on literature and aesthetics through his wit, epigrams, and exploration of estheticism. His works, such as *The Picture of Dorian Gray* and *The Importance of Being Earnest*, challenged conventional morality and showcased the relationship between beauty and moral ambiguity. Wilde's focus on the individual and emphasis on self-expression remain influential. He also contributed to the evolution of the modern stage and pushed boundaries of gender roles and sexual identity, which paved the way for future literary movements.
