The quote from Joseph Conrad's "The Secret Agent" highlights a shared simplicity in thought among people, regardless of their social status. It suggests that those who possess a serene disposition, whether wealthy or poor, often approach life with a clear and uncomplicated mindset. This tranquility of mind allows individuals to navigate the complexities of existence with ease, focusing on what truly matters rather than getting lost in convoluted ideas.

Conrad’s observation reflects a profound truth about human nature, implying that true wisdom often comes not from intellectual sophistication but from a sense of peace and clarity. The ability to maintain simplicity in thought can foster understanding and connection between diverse groups, reinforcing the notion that regardless of one's background, a serene soul shares a common perspective on life’s essential truths.
