"안티테제" (antithesis) is a rhetorical device that contrasts opposing ideas or concepts to highlight differences. It is often used in literature, philosophy, and speeches to create a more profound understanding of a subject by presenting conflicting viewpoints. This technique can enhance the emotional impact of a message and engage the audience more effectively. In philosophy, Hegel introduced the concept of thesis, antithesis, and synthesis, where the antithesis represents the opposition to the initial idea (thesis). This dialectical method illustrates how conflicting ideas can lead to a new understanding or resolution, emphasizing the dynamic nature of thought and progress.
