In "Twenty Years After," Alexandre Dumas emphasizes the importance of prioritizing unseen principles over material appearances when faced with uncertainty. The quote suggests that true value lies not in what can be seen or touched, but in the deeper truths and ideals that guide our decisions and actions. This idea encourages individuals to look beyond surface-level distractions and focus on the foundational beliefs that drive their understanding of the world.

The notion of choosing invisible principles over material concerns resonates with readers as it highlights the significance of integrity, purpose, and inner conviction. By nurturing these deeper values, one can navigate life's complexities with clarity and conviction, ultimately achieving greater fulfillment and a meaningful existence.
