"Here also is a dictum in respect to the political position and power of islands which, could the author be suddenly reanimated, he would find had been startlingly disproved in the course of a few generations. "As concerning the situation of ilands," says Peter, "whether commodious or not, this is my judgment. If a Prince desire rather to keep than augment his dominions, no place fitter for his abode than an iland, as being by itself and Nature sufficiently defensible. But if a King be minded to adde continually unto his empire, an iland is no fit seat for him; because, partly by the uncertainty of winds and seas, partly by the longsomenesse of the wayes, he is not so well able to supply and keep such forces as he hath on the continent. An example hereof is England, which hath even to admiration repelled the most puissant monarch of Europe [ Philip II of Spain ]; but for the causes above-named cannot show any of her winnings on the firme land: though shee hath attempted and atchieved as many glorious exploits as any country in the world." See what genius and energy can effect, even in spite of what seems a very plausible theory. Our insular position remains unchanged; yet we have acquired and maintained a foreign empire greater than Alexander's. On the other hand, Spain, then "the most puissant" of monarchies, has been stripped of nearly all its foreign possessions."
