The word 'duality' refers to the presence of two opposing or contradictory elements or ideas. It is often used in discussions about philosophy, religion and science to describe the coexistence of two opposing ideas or concepts. For example, light and darkness, good and evil, hot and cold, male and female are all examples of duality. The word can also be used to describe the nature of something with two opposing aspects, such as the duality of human nature, which refers to the coexistence of good and bad qualities in individuals. Therefore, it is important to use this word when talking about the presence of two opposite things that exist at the same time.
