Since Aristotle , the physical (the subject matter of physics , properly τὰ φυσικά "natural things") has often been contrasted with metaphysical (the subject of metaphysics ).  "Physis, translated since the Third Century . usually as "nature" and less frequently as "essence", means one thing for the presocratic philosophers and quite another thing for Plato."  Physis is a great example of a keyword that was very important in classical rhetoric and helped define Greek language, but over time was modified through culture changes into a related, but new word. 
Between 1671 and 1677 William Penn made trips to Germany on behalf of the Quaker faith, resulting in a German settlement that was symbolic in two ways: it was a specifically German-speaking ward, and it comprised religious dissenters. Pennsylvania has remained the heartland for various branches of Anabaptists: Old Order Mennonites, Ephrata Cloisters, Brethren, and Amish. Pennsylvania also became home for many Lutheran refugees from Catholic provinces (., Salzburg), as well as for German Catholics who also had been discriminated against in their home country.
