Every circumstance of their past and every consideration of their present convinced the patriot of the infinite pleasure and value of home rule and they had codified their opinions into a political philosophy which not only justified their semi-independence and disregard of acts of Parliament, but would also justify them in breaking off from England, at the first opportunity and becoming absolutely independent. They had gathered this philosophy from the works of certain European writers—Grotius, Puffendorf, Locke, Burlamaqui, Beccaria, Montesquieu, and others—who had applied to politics and government the doctrines of religious liberty and the right of private judgment which had been developed by the Reformation. Being such extreme Protestants, and having carried so far the religious ideas of the Reformation, the colonists naturally accepted in their fullest meaning the political principles of the Reformation. If we are looking for profound influences in the Revolution, it would be difficult to find any that were stronger than two of the writers just mentioned, Locke and Burlamaqui, whose books had a vast effect in the break-up of the British empire which we are about to record. Beginning with Grotius, who was born in 1582, and ending with Montesquieu, who died in 1755, the writers mentioned covered a period of about two hundred years of political investigation, thought and experience. In fact, they covered the period since the Reformation. They represented the effect of the Reformation on political thought. They represented also all those nations whose opinions on such subjects were worth anything. Grotius was a Dutchman, Puffendorf a German, Locke an Englishman, Burlamaqui an Italian Swiss, and Montesquieu a Frenchman. Hooker, who lived from 1553 to 1600, and whom Locke cites so freely, might be included in the number, and that would make the period quite two hundred years. Hooker, in his “Ecclesiastical Polity,” declared very emphatically that governments could not be legitimate unless they rested on the consent of the governed; and this principle forms the foundation of Locke’s famous essays. There were, of course, other minor writers; and the colonists relied upon them all; but seldom troubled themselves to read the works of the earlier ones, or to read Hutchinson, Clarke and other followers of that school, because Locke, Burlamaqui, and Beccaria had summarized them all and brought them down to date. To this day any one going to the Philadelphia Library, and asking for No. 77, can take in his hands the identical, well-worn volume of Burlamaqui which delegates to the Congress and many an unsettled Philadelphian read with earnest, anxious minds. It was among the first books that the library had obtained; and perhaps the most important and effective book it has ever owned.
