Ralph Waldo Emerson is one of the most important figures in American nature writing, yet until now readers have had no book devoted to this central theme in his work. The Best Read Naturalist fills this lacuna, placing several of Emerson’s lesser-known pieces of nature writing in conversation with his canonical essays. Organized chronologically, the thirteen selections-made up of sermons, lectures, addresses, and essays-reveal an engagement with natural history that spanned Emerson’s career. As we watch him grapple with what he called the book of nature, a more environmentally connected thinker emerges-a green Emerson deeply concerned with the physical world and fascinated with the ability of science to reveal a correspondence between the order of nature and that of the mind. The Best Read Naturalist illuminates the vital influence that the study of natural history had on the development of Emerson’s mature philosophy.
