Nathaniel Hawthorne's "The House of the Seven Gables" explores the theme of strength in contrast to weakness. The quote "Strength is incomprehensible by weakness, and, therefore, the more terrible" suggests that those who are strong may not fully understand or empathize with the struggles of the weak. This lack of comprehension can lead to a terrifying dynamic, as strength can sometimes manifest in oppressive or harsh ways.

The idea implies that true strength comes with a responsibility to understand and aid those who are weaker. Conversely, when strength is forged without empathy, it can become a source of fear and conflict. Hawthorne challenges readers to reflect on the nature of power and its impact on human relationships within the intricate narrative of the novel.
