Answer: In "The Wild Swans at Coole," Yeats view of nature is that it is timeless and beautiful.
Explanation: Although Yeats sees nature as timeless and beautiful, his view on the passage of time for man is less joyful, in fact the mood of the poem seems mournful. He writes about the loss of passion and love as time passes for man, with only nature and the swans being constant in their being. The swan's flight indicates that passage of time.
