Step-by-step explanation:
The emotion speaker in the poem "The Lake Isle of Innisfree" by William Butler Yeats feels a profound sense of peace and yearning for the simplicity and tranquility of nature. Yeats expresses a longing to return to Innisfree, where he can live a solitary, quiet life, close to nature. The poem conveys a deep connection with the natural world and a desire to escape the complexities of modern life. This resonates with the concept of the sentimental as beauty's "sloppy cousin, the enemy," as explored in one of the provided texts, indicating that sentimentality can evoke both positive and negative emotions regarding the natural environment and one's relationship to it. Moreover, the speaker's state of mind reflects a melancholic tone, emphasizing a restlessness similar to the incessant motion and yearning of water described by Arthur Symons. The idea of being overwhelmed by the natural world's beauty and power is evident in the mentioned phrases such as the sky turning "blood-red" and the sense of a "vast, endless scream passing through nature".
