In her novel "The Historian," Elizabeth Kostova reflects on the persistence of humanity's darker tendencies throughout history. The quote suggests that negative impulses and behaviors can endure across generations and eras, highlighting the ongoing struggle between good and evil in society. This idea underscores the complexity of human nature and the challenges faced in overcoming historical injustices and malice.

Conversely, Kostova points out that the positive actions and efforts of individuals may not leave a lasting impact, often fading away with their lives. This contrast emphasizes the fleeting nature of personal achievements and the difficulties in instigating meaningful change. The quote invites readers to consider the legacy of their choices and the importance of striving for a better future, despite the weight of humanity's darker past.
