In "A Clockwork Orange," Anthony Burgess presents the idea that both good and evil are necessary components of human existence. The concept emphasizes that without the presence of evil, true moral choice would not be possible. This suggests that the nature of humanity involves a constant struggle between these opposing forces, creating the complexity necessary for individuals to make meaningful ethical decisions.

The quote reflects a philosophical perspective that sees the coexistence of good and evil as foundational to moral understanding. By arguing that it is unnatural to be wholly good or wholly evil, Burgess highlights the importance of the choices people make in navigating their moral landscape. This interplay between moral entities is essential for life's dynamism, allowing individuals to develop their moral compass through the challenges they face.
