The quote from "Don Quixote" by Miguel de Cervantes suggests that a father's affection for his son can cloud his judgment. Even when a son possesses unattractive traits or behaviors, the father's love may prevent him from recognizing these flaws. Instead, he may perceive these shortcomings as unique qualities or gifts, reflecting a deep parental bias.

This dynamic highlights the complexities of parental love and its influence on perception. A father’s admiration can lead him to interpret his son's defects positively, showcasing the often irrational nature of emotional attachment. This theme explores the interplay between love and perception, raising questions about objectivity in relationships.
