Final answer:
The passage suggests the theme of the overwhelming power of nature and human insignificance in Naturalism, where individuals are depicted as powerless against inherited and environmental forces.
Step-by-step explanation:
One passage that expresses a theme or principle of Naturalism implicitly is:
“In Naturalistic works, nature is depicted as indifferent, sometimes even hostile, to humans, and humans are often depicted as small, insignificant, nameless losers in battles against an all-powerful nature.”
The theme suggested here is the overwhelming power of nature and the insignificance of human beings in the face of natural forces. This theme reflects the Naturalism belief that individuals are subject to forces beyond their control such as genetics and environment, which dictate their behavior and fate. Characters in Naturalistic literature are often shown as helpless and trapped by these forces, unable to exert free will or change their predetermined outcomes.
