Oh! I just remembered. For anyone out there who might be interested in learning more about Peirce, a really good place to find some more is a novel by A.D. Manning called Love Story Logic. It is unpublished, but he has recently put up the first four chapters on the internet, at the following link: http://linguistics.byu.edu/classes/Ling230am/stories/LSLpartI.pdf. If you want to read the rest of it, you can email him at the address on the copyright page.
