(Most Neoplatonists take there to be nine Deductions.  Rangos (2014), building on remarks in Grote (1865) and a seminar of Heidegger from 1930–31, argues that the Appendix is not merely a ninth Deduction, but also plays a special role in the overall scheme of Deductions.) There is some controversy over the principles of division that Plato uses to generate the groupings.
