Wordsworth's Poetical Works are famous for their glorification of nature. These poems emphasize goodness and spirituality, and put forth the idea that only through a true understanding of and connection to nature can humans reach the highest levels of nobility and purity. Society is presented as a corrupting influence; the poems, which often describe their speaker wandering through a pastoral scene, are odes to natural beauty. Although these works also explore themes of melancholy and death, they are ultimately positive overall, showcasing the redemptive power of nature.
