Developmental progress in ancient Greek ethics

Starting from a neo-Kohlbergian approach to moral reasoning, major moral-cognitive advancements are reconstructed from the historical development of ancient Greek ethical philosophy. Kohlberg's stage theory is basically retained and supplemented by a developmental logic which allows us to (re)construct moral stages from their respective predecessors. This logical or dynamical approach, however, yields a new stage taxonomy, which is significantly different from and more detailed than Kohlberg's. Applying the new approach to ancient Greek ethics nine distinct stages within the historical process can be made out and analysed. As far as the argument and the available historical evidence go, the real historical development appears to be well accommodated by the suggested theory.
