"Nature" is what we see

"Nature" is what  we see  is a relatively short poem with only one stanza. However, the poem can in fact be divided into three parts, each starts with "nature is what we see/hear/know". The rhyme is basically an "ee" sound, which makes the poem more fluent like music. However, the third part has only on "ee" sound at the end, which actually emphasizes this word and indicate the difference of the last part: the previous two parts with at least two "ee" sounds are mostly talking about material substances while the characters in the third part become abstract. The emotion in the first two parts is light, like a young girl dancing in the nature and singing out all the names of substances around her. Nevertheless, in the third part, she seems to stop and think more about the environment, the nature which contains her. 

The poem is comparing material with abstract, minute with significant in the nature. In the first and second parts, hill, afternoon, sea and thunder are  enormous objects in the nature while Squirrel, Eclipse, the Bumble bee, bobolink and cricket are really insignificant substances. Nevertheless, all these very different notions match perfectly and form the illusory but fine heaven and harmony. In the third part, she contrasts human wisdom with nature's complicity, indicating that although human can see and hear nature, we still cannot fully understand the magnificent nature and how it is constructed. In conclusion, nature, which contains and hugs all kind of contrast and differences, not only produces heaven and melody, but also stays intangible and mysterious for human.
