In Penelope Fitzgerald's "The Bookshop," the quote reflects a deep introspection about the nature of humanity and societal roles. It suggests that individuals often deceive themselves into believing that humanity is not divided into oppressors and the oppressed. This illusion is temporary, as those in positions of power inevitably assert their dominance over others, showcasing a harsh reality of human interactions.

Furthermore, the quote emphasizes the futility of willpower without direction or purpose. It implies that strength and determination lack significance unless they are directed toward meaningful goals. This notion invites readers to contemplate the motivations behind their actions and the importance of understanding the social dynamics at play in their lives.
