In "The Man in the Iron Mask" by Alexandre Dumas, the characters grapple with the concept of enduring goodness. Aramis reflects on the idea that true goodness remains constant and unchanging, much like the character Athos, who embodies unwavering moral principles. This contemplation suggests a deep philosophical insight into the nature of virtue and its permanence.

The notion that goodness is unalterable contrasts with the fluctuating circumstances of characters' lives. Dumas uses Aramis's thoughts to explore themes of loyalty, honor, and the struggles between personal aspirations and ethical choices, ultimately reinforcing the value of steadfast moral integrity amidst chaos.
