Truly speaking, Shelley is a difficult poet; to follow his meaning with ease and security requires a nimble and poetic intelligence, which comparatively few readers are possessed of. But the main reason why this poem is popular is because it has human interest: it is filled with the enthusiasm of humanity and embodies his observation of life. We will agree with this judgment and all who care to read the thoughts of a great poet upon many points of high literary and philosophical interest will find a rich treat in Percy Bysshe Shelley’s The Moon.
