Hobbes' Leviathan might be the very foundation for modern states -- it might not be an idea of statehood built on the Summum bonum or highest good, but arguably I'll point this out just to show the importance of understanding this difference.
Hobbes Leviathan promotes a kind of State Corporatism (State as one individual) like Plato advocates.
Hobbes also, on the cover of De Cive, contrasts Imperium and Libertas -- like Plato does between Persian Despotism and Athenian Liberty.
Plato Republic:
>And the city whose state is most like that of an individual man.
>The best governed state most nearly resembles such an organism.
Check. Hobbes makes the State like that of an individual man.
Plato Republic:
>so the entire city may come to be not a multiplicity but a unity.
That is also confirmed in Hobbes' Leviathan: for Hobbes his State is more than just a partnership of clans bonded by a common idea, like Orthodoxy is.
In Hobbes words:
>This is more than Consent, or Concord; it is a real Unity of them all, in one and the same Person
And
>The error concerning mixed government has proceeded from want of understanding of what is meant by this word body politic, and how it signifies not the concord, but the union of many men.
