Secular plays are often contrasted with religious plays, which are plays that have a religious theme or purpose. Religious plays can be used to teach religious doctrine, to inspire religious devotion, or to simply provide entertainment. Some examples of religious plays include the medieval mystery plays, the Passion plays, and the morality plays.
While secular plays do not have a religious theme or purpose, they can still be used to explore important philosophical or moral issues. For example, Shakespeare's "Hamlet" explores the themes of revenge, madness, and mortality, while Moliere's "Tartuffe" explores the theme of hypocrisy. Secular plays can also be used to simply entertain audiences, and can provide a much-needed escape from the stresses of everyday life.
