He who sees a play that is regular, and answerable to the rules of poetry, is pleased with the comic part, informed by the serious, surprised at the variety of accidents, improved by the language, warned by the frauds, instructed by examples, incensed against vice, and enamoured with virtue; for a good play must cause all these emotions in the soul of him that sees it, though he were never so insensible and unpolished.
In "Don Quixote," Miguel de Cervantes Saavedra reflects on the multifaceted nature of theatre and its impact on the audience. He suggests that a well-structured play not only entertains but also engages the viewer's emotions across a spectrum. A play that adheres to the principles of poetry is capable of evoking laughter through its comedic elements while also offering serious insights, captivating the audience with unexpected developments and enriched language.
Furthermore, Cervantes emphasizes the moral and educational value of theatre. A good play can provoke thoughts against wrongdoing while simultaneously fostering admiration for virtue. It serves as a conduit for introspection and growth, affecting even those who may seem indifferent or unrefined. The emotional journey that a compelling performance provides highlights the profound connection between art and the human experience.
