Profane literature likely refers to works with vulgar language and explicit content, contrasting with traditional literature's themes, references, or symbolism.

When discussing the concept of profane literature, Prof. Rearick may have referred to works that typify qualities opposite to those upheld by romantic and revered literature.
Profane literature could involve vulgar language and explicit content, which is a stark contrast to the complex and abstract themes, historical and cultural references, or symbolism and allegory found in more traditional literary works. \
