Final answer:
Postmodern literature is the genre that views multiple realities skeptically and challenges the concept of a singular truth. It embraces a diversity of experiences and presents a relative view of reality as defined by individual perspectives.
Step-by-step explanation:
Postmodern Literature:
The type of literature that sees multiple realities and is particularly skeptical of a monolithic version of truth is postmodern literature. This literary movement rejects the notion of a singular, objective reality and instead suggests that there are multiple, equally valid realities shaped by individual perspectives and cultural contexts.
In contrast, magical realism includes fantastical elements in realistic narratives, but it doesn't inherently question the nature of reality or truth as postmodern literature does. Realistic fiction and historical fiction strive for authenticity in the depiction of their respective genres but typically adhere to a single, coherent reality. It is postmodernism that stands out for its philosophical skepticism and creation of multiple knowable worlds, as emphasized by writers and critics like Brian McHale.
