Abstract
The essay examines passages from Henry David Thoreau's journal and Walden as illustrations of Goethe's phenomenological approach to nature, focusing on the influence on Thoreau of Goethe's discovery of metamorphosis as the generative principle of plants, and his proclamation that "first to last the plant is nothing but leaf." The essay shows how Goethe and Thoreau bring a poet's heightened awareness of language to their scientific observation of nature, and argues that their attention to figurative language, its limits as well as its possibilities, helps them and their readers to develop the needed flexibility to think along with rather than merely about nature.
