The "coincidence of opposites" is a philosophical concept that suggests that seemingly contradictory elements can coexist and even complement each other. This idea is often explored in various fields, including philosophy, psychology, and art. It highlights how opposites, such as light and darkness or joy and sorrow, can create a more profound understanding of existence. In literature and mythology, the coincidence of opposites is frequently illustrated through characters or themes that embody duality. For example, the Yin and Yang symbol represents how opposing forces are interconnected and interdependent. This concept encourages a holistic view of life, recognizing that balance often arises from the interplay of contrasting elements.
