I read "Nature" and the first series of Essays in the collection of his works. My motivation to read Emerson is my project to read the American authors in the Hall of Fame of Great Americans (yes, this Hall of Fame exists, though no longer active). Emerson was in the first batch of American authors to be elected into the Hall of Fame when it opened in 1900. I read some Emerson in school, but it was time to revisit his work as an adult, and I'm certainly glad I did. I enjoyed the readings very much - I read one essay at a time with breaks in between, rather than reading straight through. I was inspired, challenged, comforted (and sometimes bored) with the essays. I intended to read Essays II as well, but after completing all the pieces in Essays I, I was ready to move on to other authors. If I return to Emerson, I think I would re-read the essays I already read - they are meaty and worth more time. If you haven't read Emerson or haven't read him since high school, I recommend reading at least an essay or two.
