Final answer:
The last two lines of "The Rhodora" and "To a Waterfowl" both express a sense of unity and connection with nature, emphasizing the beauty and purpose found in the natural world.
Step-by-step explanation:
In the concluding lines of "The Rhodora," Ralph Waldo Emerson reflects on the interconnectedness of all elements in nature, highlighting the beauty of the rhodora flower as part of the grand tapestry of creation. Similarly, in William Cullen Bryant's "To a Waterfowl," the final lines convey a profound connection between the speaker's journey and the bird's flight, suggesting a purposeful design in the natural order. Both poets use their concluding verses to convey a sense of harmony and purpose within the larger scope of the natural world.
Examining the common themes in the concluding lines of these poems underscores the transcendentalist perspective prevalent in American literature during the 19th century. The poets celebrate the beauty of nature and emphasize the spiritual connection between humans and the natural world, reflecting a philosophical movement that sought to explore the divine in the ordinary aspects of life.
