Answer:
Brotherly love
Step-by-step explanation:
A particularly predominant topic in Whitman's poetry is the subject of brotherly love. Whitman believed that society was very divided in ways that greatly damaged it. He thought that people were not always aware of their commonalities and instead chose to focus on their differences. However, Whitman also believed that people were in fact interconnected, and that humankind was a sort of large family. He often used this theme in his poetry.
