Final answer:
Emily Dickinson's work is reflective of the Romanticism movement, which emphasized nature, personal expression, and emotional depth as reactions to the Industrial Revolution.
Step-by-step explanation:
To which of the following was Dickinson responding in his letters? The answer can be understood by considering the cultural context in which Emily Dickinson wrote her poetry. Dickinson, along with other writers such as Walt Whitman, is often categorized within the literary movement of Romanticism. This movement, which started as a response to the Industrial Revolution and encompassed themes of nature, the ordinary person, and self-expression, heavily influenced Dickinson's work. Thus, in Dickinson's letters and poetry, one can see the elements of Romanticism as a response to the changing world around her.
Romantic writers placed a high emphasis on the beauty and power of nature, the significance of the individual, and the value of emotion and imagination over rationality that had been heralded during the Age of Enlightenment. Although transcendentalism also emerged during this period, focusing on self-reliance and individualism, and was a cultural development parallel to Romanticism, Dickinson's letters more directly reflect the characteristics and themes of Romanticism.
