 Piety towards nature was also a main theme of William Wordsworth, whose poetry was in vogue in America in the 1820s. Wordsworth’s depiction of an active and powerful mind cohered with the shaping power of the mind that his collaborator in the Lyrical Ballads, Samuel Taylor Coleridge, traced to Kant. The idea of such power pervades Emerson’s Nature, where he writes of nature as “obedient” to spirit and counsels each of us to “Build … your own world.” Wordsworth has his more receptive mode as well, in which he calls for “a heart that watches and receives” (in “The Tables Turned”), and we find Emerson’s receptive mode from Nature onward, as when he recounts an ecstatic experience in the woods: “I become a transparent eyeball. I am nothing; I see all; The currents of the universal being circulate through me.” (O, 6).
