In "Don Quijote of La Mancha," Miguel de Cervantes Saavedra presents the theme of a noble pursuit that often goes unrecognized, comparing it to preaching in a deserted area. This metaphor reflects the idea that one's efforts may be in vain if there is no audience to appreciate them. Don Quijote's quest for chivalry and justice is noble, yet he frequently encounters misunderstanding and indifference from those around him, underscoring the loneliness of his ideals.

The phrase "mashed in cold iron" evokes the harsh reality that often meets well-intentioned aspirations. Throughout the novel, Don Quijote's encounters with the brutal realities of the world serve to challenge his dreams and ideals. Instead of finding glory and recognition, he faces resistance and ridicule, symbolizing the struggles of any idealist in a world that can sometimes be unforgiving and harsh. This stark contrast emphasizes the complexities of striving for noble goals in an often indifferent society.
