1. Emerson now outlines three main points concerning our use of nature's beauty: its medicinal qualities, its spiritual elements, and its intellectual properties.
2. This metaphor shows how humans and nature act differently. Emerson says that humans are “ashamed” of their own thoughts and feelings, and he then goes on to point out that nature is never “ashamed.” He calls for humans to return to their natural state and to stop overthinking and worrisome behaviour.
I do apologise, but I do not have the answer to your third question.
