The last royal projectors with whom the world has been troubled, were Charles of Sweden and the Czar of Muscovy. Charles, if any judgment may be formed of his designs by his measures and his inquiries, had purposed first to dethrone the Czar, then to lead his army through pathless deserts into China, thence to make his way by the sword through the whole circuit of Asia, and by the conquest of Turkey to unite Sweden with his new dominions: but this mighty project was crushed at Pultowa; and Charles has since been considered as a madman by those powers, who sent their ambassadors to solicit his friendship, and their generals "to learn under him the art of war." The Czar found employment sufficient in his own dominions, and amused himself in digging canals, and building cities: murdering his subjects with insufferable fatigues, and transplanting nations from one corner of his dominions to another, without regretting the thousands that perished on the way: but he attained his end, he made his people formidable, and is numbered by fame among the demi-gods. I am far from intending to vindicate the sanguinary projects of heroes and conquerors, and would wish rather to diminish the reputation of their success, than the infamy of their miscarriages: for I cannot conceive, why he that has burned cities, wasted nations, and filled the world with horrour and desolation, should be more kindly regarded by mankind, than he that died in the rudiments of wickedness; why he that accomplished mischief should be glorious, and he that only endeavoured it should be criminal. I would wish Cæsar and Catiline, Xerxes and Alexander, Charles and Peter, huddled together in obscurity or detestation. But there is another species of projectors, to whom I would willingly conciliate mankind; whose ends are generally laudable, and whose labours are innocent; who are searching out new powers of nature, or contriving new works of art; but who are yet persecuted with incessant obloquy, and whom the universal contempt with which they are treated, often debars from that success which their industry would obtain, if it were permitted to act without opposition. They who find themselves inclined to censure new undertakings, only because they are new, should consider, that the folly of projection is very seldom the folly of a fool; it is commonly the ebullition of a capacious mind, crowded with variety of knowledge, and heated with intenseness of thought; it proceeds often from the consciousness of uncommon powers, from the confidence of those, who having already done much, are easily persuaded that they can do more. When Rowley had completed the orrery, he attempted the perpetual motion; when Boyle had exhausted the secrets of vulgar chymistry, he turned his thoughts to the work of transmutation[1].
