Improving the science of politics

[DEMOREP1 at aol.com]

The below is an excerpt from Federalist No. 9, para. 3 by Alexander
Hamilton---

The science of politics, however, like most other sciences, has received
great improvement. The efficacy of various principles is now well understood,
which were either not known at all, or imperfectly known to the ancients. The
regular distribution of power into distinct departments; the introduction of
legislative balances and checks; the institution of courts composed of judges
holding their offices during good behavior; the representation of the people
in the legislature by deputies of their own election: these are wholly new
discoveries, or have made their principal progress towards perfection in
modern times. They are means, and powerful means, by which the excellences of
republican government may be retained and its imperfections lessened or
avoided.

Proportional representation methods for legislative bodies and single winner
methods for executive and judicial elections were not available in 1787-1788
when Hamilton wrote the above.  The "progress towards perfection" continues.
