Final answer:
Famous writers use humor, irony, and satire to engage readers and present serious messages in a humorous way. The 'intentional fallacy' refers to the notion that authors' intentions should not be the sole determinant of a text's meaning. Effective writing in plays, stories, and other literary forms is determined by how well themes are conveyed and audiences are engaged.
Step-by-step explanation:
Writers such as Charles Dickens and Jonathan Swift utilized humor, irony, and satire to engage readers and compellingly convey their messages. The use of these literary techniques allows the writer to present a scenario or character in a humorous way, yet simultaneously points to a serious underlying message or criticism. The intentional fallacy suggests that the author's intended meaning should not solely dictate one's understanding of a literary work. Instead, readers may discover meanings the author never explicitly intended. Moreover, a close look at famous plays reveals that playwrights craft their works to invoke a range of emotions, and whether the text is designed to amuse or disturb, its ultimate effectiveness is measured by how well it can convey themes and engage the audience.
