Based on the information in "Earth's Eye," the best description of the influence of Ralph Waldo Emerson on Thoreau is that Emerson inspired Thoreau to abandon city life and embrace nature. This is evident in the text when it says, "He found his love for nature through the guidance of his mentor, Ralph Waldo Emerson."
Emerson was a renowned philosopher and writer who advocated for a connection with nature and self-reliance. Thoreau, being a close friend and follower of Emerson, was greatly influenced by these ideas. Thoreau was inspired to live a simple life close to nature, which led him to build a cabin near Walden Pond. Through his experiences in nature, Thoreau wrote his famous work "Walden," which reflects his deep appreciation for the natural world.
It is important to note that while Emerson influenced Thoreau's views on nature, he did not teach Thoreau how to survive in the wilderness or become a successful author. Emerson's impact on Thoreau was more focused on philosophical and spiritual aspects, encouraging him to seek a deeper connection with nature and live a simpler life.
