Final answer:
In these stanzas, the two abstract ideas that are personified are a) evil and good.
Step-by-step explanation:
In the given stanzas, the two abstract ideas that are personified are evil and good.
The lines suggest that there is no inherent good or evil, but rather these concepts are human creations that change over time and vary based on different perspectives and cultures. The personification of evil and good allows these ideas to be treated as concrete entities, even though they are abstract concepts.
For example, in stanza 1, the narrator discusses the tendency of humans to create abstractions and treat them as if they are tangible. This behavior is comparable to scientific modeling, where abstract ideas are represented in a concrete way for better understanding.
