Leadership, History, Cosmopolity

If the Idea of the Good in the Republic is identical to the World-Soul of the Timaeus, then the Polis harmonized by the Philosopher-King, in accordance with a vision of the Idea of the Good, can be either only a Cosmopolity, or a more localized Polity in transition to be incorporated in an eventual more comprehensive entity.  But, it is not until Kant, Hegel, and Marx that the historicization of Political Philosophy begins to be considered.  Accordingly, all prior Political Philosophy, Ancient and Modern, has become obsolete in many of its details, e. g. that self-preservation is the sole motivation for an individual human entering into association with others.  Likewise, not taking into consideration that an effective Sovereign must have, as has previously discussed, diachronic Leadership qualities, i. e. by means of which a local Polity might constitute an episode in the historical progression towards a Cosmopolity, is a deficiency in those models.
