In the quote from "Don Quixote" by Miguel de Cervantes, the author encapsulates the enduring nature of truth in contrast to falsehoods. He suggests that while lies may be pervasive, they will ultimately never prevail over the truth. This analogy of truth floating on water like oil illustrates its resilience and ability to stand out, even amidst a sea of deception.

Cervantes emphasizes that the essence of truth is unyielding; it may become obscured temporarily, but it will always thrive and emerge intact. This perspective invites readers to reflect on the power of honesty and integrity, reminding us that, regardless of circumstances, truth will eventually shine through and dominate over false narratives.
