In "Don Quixote," Miguel de Cervantes Saavedra illustrates a contrast between idealism and reality through a critique of various human attributes. He discusses how supposed positive traits like diligence, work, and courage can become flawed when taken to extremes or misapplied, reflecting on the paradoxes within virtues. This commentary implies that such qualities can lead to laziness, idleness, and arrogance, blurring the line between noble intentions and personal vices.

The mention of the "ages of gold" evokes a nostalgic longing for a time when values were upheld in a seemingly pure form. This idea suggests that the ideals of chivalry and honor have deteriorated in contemporary society, as evidenced by the emptiness of practicing virtues without genuine commitment. Cervantes critiques the disconnect between theory and practice, particularly in areas like warfare, highlighting how past glory may not translate into present reality.
