It must be acknowledged, that for all these Improvements, we are obliged to the Arts and Sciences. They are as it were the first moving Force of Power in any Country; and if we take a Survey of all the Nations of the Earth, we shall find, that those Monarchs, who encourage Learning, and support Academies, are able to extend their Dominions farther than those, who, by a total Attention to Military Discipline, (though even that too depends upon the Sciences) neglect the Cultivation of that Learning, upon the Support of which, the Extension of their Dominions to foreign Parts depends. It is to the Invention of Astronomers, Mechanics, and Opticians, that we owe the principal Instruments, which are made Use of in Navigation; to their Ingenuity we owe the Quadrant, without which we should never know our Latitude; to these we are indebted for the Telescope, by which we discover Jupiter's Satellites, and find out our Longitude; to these we owe the Explanation of the Compass; to these the Contrivances of Pullies, by which we hale up our Tackling. In short, all the Inventions, which we find in the different Machines made Use of, either by Land or Water, though by long Use they are become familiar in the Hands of illiterate Persons, were no doubt originally contrived by the Study and Ingenuity of Men of Science at Home. And if Nature should shew her dislike to a Stagnation, and express her wonted Approbation of a Vicissitude in Human Affairs; who knows, but when the Sciences are forgot in this Kingdom, and we, by that Means, lose the Art of exerting that Force, which must keep up the Dignity of England over her Colonies; who knows (which Heaven avert!) but America may see herself the Mistress of the World, and the Seat of Empire, whilst we are reduced once more to the State of unletter'd Savages; and shall in vain discharge our feeble Arrows, and cast our ill-directed Javelins, against the Sides of their perhaps Five Hundred Gun Ships of War: Or the great Mogul, with his prodigious Armies, for Want of these Arts and Sciences abovementioned, and for no other Reason, may one Day or other find himself dethroned by a Prince, who will be able to reach him, though his Dominions do lie on the other Side of an unfathomable Sea. And if these Vicissitudes should in Process of Time happen, they will be no other than what have been before. What is become of Palmyra? Where is Troy? The stately Palaces of Troy are removed into the peaceful Habitation of the once Arcadian Shepherds. And if the Disposer of all Things should so order it, Daphnis and Menalcas, may again sing their rural Songs on the very Spot, where now the Seraglio of the Grand Signior seems to bid Defiance to a whole Continent.
