In Joseph Conrad's "Heart of Darkness," the author reflects on the dark nature of imperialism, emphasizing that the conquest of lands often involves displacing people who differ in appearance. This perspective reveals that the act of colonization is not inherently noble but is instead marred by its brutal reality. The superficial justifications for such conquests reveal a deep moral quandary inherent in the process of domination over others.

However, Conrad suggests that what elevates this grim endeavor is the underlying idea that drives it. This idea is not just a superficial justification, but rather a profound belief that motivates individuals to commit themselves to a cause, worthy or not. This commitment encourages individuals to worship the concept itself, potentially leading to significant sacrifices in its name, emphasizing the complexities of human motivations behind imperialistic pursuits.
