The only resistance ever made to Louis XIV was from religion. - John Dalberg-Acton, 1st Baron Acton

The tide was running fast when the Reformation began at Wittenberg, and it was to be expected that Luther’s influence would stem the flood of absolutism. For he was confronted everywhere by the compact alliance of the Church with the State; and great part of his country was governed by hostile potentates who were prelates of the court of Rome. He had, indeed, more to fear from temporal than from spiritual foes.

The idea that religious liberty is the generating principle of civil, and that civil liberty is the necessary condition of religious, was a discovery reserved for the seventeenth century.

The great object, in trying to understand history, political, religious, literary or scientific, is to get behind men and to grasp ideas. Ideas have a radiation and development, an ancestry and posterity of their own, in which men play the part of godfathers and godmothers more than that of legitimate parents. We understand the work and place of Pascal, or Newton, or Montesquieu, or Adam Smith, when we have measured the gap between the state of astronomy, of political economy, &c., before they came and after they were gone. And the progress of the science is of more use to us than the idiosyncrasy of the man.
