This Engine has a great deal of Philosophy in it; and particularly, 'tis a wonderful Remedy against Poreing; and as it was said of Mons. Jurieu at Amsterdam, that he us'd to lose himself in himself; by the Assistance of this piece of Regularity, a Man is most effectually secur'd against bewildring Thoughts, and by direct thinking, he prevents all manner of dangerous wandring, since nothing can come to more speedy Conclusions, than that which in right Lines, points to the proper Subject of Debate. All sorts of Confusion of Thoughts are perfectly avoided and prevented in this case, and a Man is never troubled with Spleen, Hyppo, or Mute Madness, when once he has been thus under the Operation of the Screw: It prevents abundance of Capital Disasters in Men, in private Affairs; it prevents hasty Marriages, rash Vows, Duels, Quarrels, Suits at Law, and most sorts of Repentance. In the State, it saves a Government from many Inconveniences; it checks immoderate Ambition, stops Wars, Navies and Expeditions; especially it prevents Members making long Speeches when they have nothing to say; it keeps back Rebellions, Insurrections, Clashings of Houses, Occasional Bills, Tacking, &c. It has a wonderful Property in our Affairs at Sea, and has prevented many a Bloody Fight, in which a great many honest Men might have lost their Lives that are now useful Fellows, and help to Man and manage Her Majesty's Navy. What if some People are apt to charge Cowardice upon some People in those Cases? 'Tis plain that cannot be it, for he that dare incur the Resentment of the English Mob, shows more Courage than would be able to carry him through Forty Sea-fights. 'Tis therefore for want of being in this Engine, that we censure People, because they don't be knocking one another on the Head, like the People at the Bear-Garden; where, if they do not see the Blood run about, they always cry out, A Cheat; and the poor Fellows are fain to cut one another, that they may not be pull'd a pieces; where the Case is plain, they are bold for fear, and pull up Courage enough to Fight, because they are afraid of the People. This Engine prevents all sorts of Lunacies, Love-Frenzies, and Melancholy-Madness, for preserving the Thought in right Lines to direct Objects, it is impossible any Deliriums, Whimsies, or fluttering Air of Ideas, can interrupt the Man, he can never be Mad; for which reason I cannot but recommend it to my Lord S---, my Lord N---, and my Lord H-----, as absolutely necesssary to defend them from the State-Madness, which for some Ages has possest their Families, and which runs too much in the Blood. It is also an excellent Introduction to Thought, and therefore very well adapted to those People whose peculiar Talent and Praise is, That they never think at all. Of these, if his Grace of B---d would please to accept Advice from the Man in the Moon, it should be to put himself into this Engine, as a Soveraign Cure to the known Disease call'd the Thoughtless Evil.
