The quote "Victory settles a lot of arguments in most men's heads" from Robert Jordan's "The Fires of Heaven" reflects the idea that success can bring clarity and resolution to conflicts and doubts. It suggests that achieving victory can silence opposing views and reinforce the beliefs of those who emerge triumphant. This points to a common human tendency to equate success with righteousness or truth.

In many situations, the outcomes of battles or competitions can overshadow the complexities of the underlying issues, leading to a simplified narrative where the winner's perspective dominates. The quote highlights how societal perceptions are often shaped by who prevails, underscoring the powerful influence of victory in shaping opinions and attitudes.
