He [Paolo Sarpi] was one of the two foremost Italian statesmen since the Middle Ages, the other being Cavour. - Andrew Dickson White

The French philosophy of the eighteenth century was in full strength. Those were the years in which Voltaire ruled European opinion, and Turgot could not but take account of his influence. Yet no one could apparently be more unlike those who were especially named as the French philosophers of the eighteenth century. He remained reverential; he was never blasphemous, never blatant; he was careful to avoid giving needless pain or arousing fruitless discussion; and, while the tendency of his whole thinking was evidently removing him from the orthodoxy of the Church, his was a broader and deeper philosophy than that which was then dominant.

Of all tyrannies of unreason in the modern world, one holds a supremely evil preeminence. It covered the period from the middle of the sixteenth century to the middle of the seventeenth, and throughout those hundred years was waged a war of hatreds,—racial, religious, national, and personal;—of ambitions, ecclesiastical and civil;—of aspirations, patriotic and selfish;—of efforts, noble and vile. During all those weary generations Europe became one broad battlefield,—drenched in human blood and lighted from innumerable scaffolds. In this confused struggle great men appeared—heroes and martyrs, ruffians and scoundrels: all was anarchic. The dominant international gospel was that of Machiavelli.

There was strong warrant for pretensions... As far back as 1493, Pope Alexander VI had settled disputes between Spain and Portugal arising out of their rivalry in the Orient and the Occident by drawing a line from pole to pole one hundred leagues west of the Azores, giving all west of it to the Spanish, all east of it to the Portuguese. Both these nations attempted more or less persistently to exercise the sway thus given over the oceans as well as over the continent. The Portuguese forbade under heavy penalties any person, whether native or alien, to pass through the waters off the African and Brazilian coasts without special permission; the Spanish were hardly less severe toward those who without leave approached their dependencies. But, though the realization of the earth's rotundity renewed the old difficulty, and Spain and Portugal discovered that the Papal decision was futile, since all their new dominions could be approached both from the east and the west, both nations continued to maintain, as best they could, their sovereignty over the vast oceans. Other nations followed these examples.
