NECESSITY, which is allowed to be the mother of invention, has so violently agitated the wits of men at this time that it seems not at all improper, by way of distinction, to call it the Projecting Age. For though in times of war and public confusions the like humour of invention has seemed to stir, yet, without being partial to the present, it is, I think, no injury to say the past ages have never come up to the degree of projecting and inventing, as it refers to matters of negotiation and methods of civil polity, which we see this age arrived to. Nor is it a hard matter to assign probable causes of the perfection in this modern art. I am not of their melancholy opinion who ascribe it to the general poverty of the nation, since I believe it is easy to prove the nation itself, taking it as one general stock, is not at all diminished or impoverished by this long, this chargeable war, but, on the contrary, was never richer since it was inhabited. Nor am I absolutely of the opinion that we are so happy as to be wiser in this age than our forefathers; though at the same time I must own some parts of knowledge in science as well as art have received improvements in this age altogether concealed from the former. The art of war, which I take to be the highest perfection of human knowledge, is a sufficient proof of what I say, especially in conducting armies and in offensive engines. Witness the now ways of rallies, fougades, entrenchments, attacks, lodgments, and a long _et cetera_ of new inventions which want names, practised in sieges and encampments; witness the new forts of bombs and unheard-of mortars, of seven to ten ton weight, with which our fleets, standing two or three miles off at sea, can imitate God Almighty Himself and rain fire and brimstone out of heaven, as it were, upon towns built on the firm land; witness also our new-invented child of hell, the machine which carries thunder, lightning, and earthquakes in its bowels, and tears up the most impregnable fortification. But if I would search for a cause from whence it comes to pass that this age swarms with such a multitude of projectors more than usual, who—besides the innumerable conceptions, which die in the bringing forth, and (like abortions of the brain) only come into the air and dissolve—do really every day produce new contrivances, engines, and projects to get money, never before thought of; if, I say, I would examine whence this comes to pass, it must be thus:
