This is a good basic model and reminds me somewhat of the levels used in spiral-dynamics and similar systems, see the table in: http://www.spiraldynamics.org/aboutsd_overview.htm http://www.spiraldynamics.org/aboutsd_overview.htm However, only levels DH3 and upwards follow the model of including the previous levels and adding enhancements, the first 2 levels are another mini-hierarchy, and DH2 is almost a category on it's own. Perhaps this might be modelled better with a dimension-level mapping. This also follows the ethos, pathos and logos. This will allow analysis and levelling of each form of argument: DH0 -> DE:0 DH1 -> DE:1 DH2 -> DP:0 DH3 -> DL:0 DH4 -> DL:1 DH5 -> DL:2 DH6 -> DL:3 I also like the concept of DH7 which explicitly argues against the strongest form of the statement. DH7 -> DL:4
