Final answer:
William Wordsworth believed that maturity allows one to see the insignificance of the human ego in nature, as reflected in his poems which discuss the loss of nature's primacy due to humanity's focus on materialistic concerns.C is the correct answer.
Step-by-step explanation:
According to the Romantic poet William Wordsworth, maturity brings an individual to observe the insignificance of the human ego in nature.
This is seen in his poetry where he frequently uses anthropomorphism, giving nature human qualities and vice versa. In the lines provided from his poems such as "The World Is Too Much with Us," we can discern a theme of humanity losing touch with nature and thereby diminishing its own essence.
Wordsworth's poetry often demonstrates how people are alienated from nature by their own constructions and endeavors, leading to a sense of loss and yearning for a primal connection with the natural world. For instance, the desire to be 'a pagan suckled in a creed outworn' from the poem "The World Is Too Much with Us," reflects a longing to perceive the divinity in nature rather than being consumed by the modern world's preoccupations.
