Edited and with notes by Kenneth Laine Ketner. From Ketner's introduction: "Probably Peirce's draft was not sent-no original smooth copy has been found. Furthermore, this draft was probably not approved by Peirce as a final one, for it contains a few repetitions (for example, the remarks about the nature of induction). What we have here is probably complete in the sense that it seems not to be a fragment of any other piece. It stands well on its' own, and provides (in my opinion) a very reliable, if brief, guide to Peirce's thought, showing its overall structure and how semiotic fits within it. Finally, it is relatively late, being written during a particularly fruitful period of Peirce's mature career."
