Empiricism and Political Philosophy

The standard academic segregation of Philosophy and Political Science makes it difficult to appreciate that Locke is the pioneer of Empiricism in not only Epistemology, but in Political Philosophy, as well, i. e. he conceives both as a posteriori.  Thus, just as what is 'true' is whatever happens to be believed, what is 'good' is whatever happens to be agreed upon.  Furthermore, as independent of prior conditions, Truth and Goodness are a-historical, i. e. there can be no Empiricist concept of History, only a manifold of unconnected events.  Now, the American Political system is Empiricist in its electoral processes, but not so in some of its other features, e. g. check-and-balance mechanisms, the possibility of amending the Constitution, etc., in which happenstance is potentially constrained.  In those respects, the system is Experimental, insofar as a novelty is further subject to integration into what has preceded.  Accordingly, Originalism, which presumes to adhere strictly to the intentions of the Founding Fathers, expresses an extreme anti-Empiricism.
