In "Don Quijote of La Mancha," Cervantes presents the idea that beauty, much like a viper's poison, is a natural attribute that should not be condemned. The analogy emphasizes that just as the serpent cannot be held liable for its lethal venom, a woman should not be judged or scorned for her beauty. This perspective suggests that beauty is inherent and neutral, and it should not be a basis for blame or criticism.

The text further likens beauty to fire and a sword, illustrating that it does not harm those who do not engage with it. An honest woman's beauty is akin to a talent or a quality that can either enchant or challenge, depending on how it is approached. In this way, Cervantes advocates for a recognition of beauty as something that exists independently of the intentions of others, urging an understanding that it should not be misused or misinterpreted.
