"The Rime of the Ancient Mariner" opens at a wedding celebration. The wedding guest is taken by surprise by an old sailor. The sailor tells him he has a story to tell. The wedding guest listens to the sailor's wild tale of a disastrous sail.The mariner tells a tale of a trip he was captain of. The weather turns ugly and an albatross comes to help him sail out of it. He ends up shooting the albatross and his crew blame him for bringing a curse on them. Again the weather turns bad and all of his crew end up dying, leaving only the Mariner alive. The Mariner now feels it his penance for killing the albatross, that he has to tell his tale to anyone who will listen. The bird was sent to help him, and he ended up killing it.

"Love's Philosophy" is a beautiful poem about love. Percy Bysshe Shelley writes that a divine being created nature to not be alone. He states that since it was a divine creation for nature, doesn't that mean we are to be with the one we love? He shows us how beautiful nature is and that love is just as beautiful. The poem compares love and nature as the same thing.

In "The Rime of the Ancient Mariner," we see that love and nature are elements used in the poem. In this poem, the Mariner, tells his story to a wedding guest. Love is all around, yet as he goes on with his story, we see that nature has played a very ugly part of his journey. The more he goes into his tale, love and nature turn out to be used as dangerous things. Nature is used as dangerous weapon for the sailor. It kills his crew, and threatens his life as well. The wedding guest, after hearing his story, is so sad that he doesn't enter the wedding. He instead goes home and as the poem quotes "a sadder and a wiser man." In contrast, Love's Philosophy, is a happy and uplifting poem. Nature and love are used to show how beautiful they both are. A divine creation made so no one and nothing is ever alone in life. In this poem we see that nature is used to illustrate how wonderful love is. It goes on to tell us that these two things are the most important things in life. 

The comparisons of these two poems are that they both use love and nature. One is used to show how nature can be dangerous, and how that danger affects the thoughts on love. The other one shows how much nature can inspire the love and beauty of life itself.
