how does shelley present feelings of romantic love in the poem

Love's Philosophy is a love poem, written with the intention of securing a woman's affections. Shelley suggests that everything in nature has a companion, apart from himself. He therefore says to his subject that they should be companions, as it is only natural.

As such, this poem is full of the imagery of romance and love. This includes how the mountains "kiss" the heavens and how the waves "clasp one another." He therefore personifies aspects of the natural world, to suggest that romance is natural.
