Vitality and Political Philosophy

Vitality is a characteristic of an organism, which, as a unity of more or less essential parts, is distinguished from a mere contingently co-existing aggregate.  Now, Plato's concept of a Republic is unified by a Soul, and includes parts the "mother" of each of which is "necessity'.  Thus, even though Vitalism is a system usually associated with the 19th Century, notably with Bergson, the first Vitalist Political Philosophy precedes it by more than two millennia.
