Answer:
Step-by-step explanation:
False.
The "duality of man" is a concept that has been explored by many writers, including Gothic writers, but it refers to the idea that humans have both good and evil, or light and dark, aspects to their nature. It is not specifically about the conflict between physical and mental existence.
In Gothic literature, the duality of man is often used to explore the dark side of human nature and the ways in which people are capable of committing heinous acts. It can also be used to create complex characters who struggle with their own moral ambiguity.
