I've read both "Experience and Nature" and "How We Think" and can recommend both. "How We Think" was published first and is shorter - would make for a good introduction to Dewey. "Experience and Nature" is longer and has more weight but is also more work to read. I haven't read more than excerpts from his other works so I can't add much. Otherwise, I intend to read "The Public and its Problems" which is supposed to be a good work on democracy.
