Question

Why do authors use rhetorical devices in essays

Answer 1

To convince the reader that what they are writing about is true and correct, and to add a deeper meaning and depth to their writing. 

Answer 2

Also known as persuasive device or stylistic device, the rhetorical device is a technique that is often used by an author or speaker to express something that is intended to change the mind of the listener or reader about the subject. This can be done by emotional display, logical reasoning, and other ways. Although it can actually evoke a strong emotional response, it isn't the goal of the rhetorical devices.
