Political Philosophy and the United States

The arrival of the United States, as expressed in the Constitution, presents a counter-example to much of the preceding Political Philosophy.  It is a product of collective construction, a response to specific historical circumstances, dubbed an "experiment" because of its uncertain future.  In that context, ideas such as Freedom have value not as absolute truths, but as sound building materials.  Likewise, that it might be a response to biological need does not guarantee modal Necessity of success as a viable social organization.  And, it demonstrates what gets suppressed in Plato's leap from a vision of the Idea of Good to the effecting of social harmony--Reason that is both Techne and Experimental.
