Sympathy in picturesque poetry

In the Theory of Moral Senitments (1759), Adam Smith argues:

“it is by the imagination only that we can form any conception of what are [another person’s] sensations... By the imagination we place ourselves in his situation, we conceive ourselves enduring all the same torments, we enter as it were into his body, and become in some measure the same person with him, and thence form some idea of his sensations, and even feel something which, though weaker in degree, is not altogether unlike them.”

“But whatever may be the cause of sympathy, or however it may be excited, nothing pleases us more than to observe in other men a fellow feeling with all the emotions of our own breast; nor are we ever so much shocked as by the appearance of the contrary.”

Consider how this theory of sentiment can help us understand the pleasure in Bowle's sonnets, and the role that Dorothy plays in Wordsworth's "Tintern Abbey."
