As to the Effects of Mathematical thinking, what Volumes might be writ of it will more easily appear, if we consider the wondrous Usefulness of this Engine in all humane Affairs; as of War, Peace, Justice, Injuries, Passion, Love, Marriage, Trade, Policy, and Religion. When a Man has been screw'd into himself, and brought by this Art to a Regularity of Thought, he never commits any Absurdity after it; his Actions are squared by the same Lines, for Action is but the Consequence of Thinking; and he that acts before he thinks, sets humane Nature with the bottom upward. M. would never have made his Speech, nor the famous B----ly wrote a Book, if ever they had been in this thinking Engine: One would have never told us of Nations he never saw, nor the other told us, he had seen a great many, and was never the Wiser. H. had never ruin'd his Family to Marry Whore, Thief and Beggar-Woman, in one Salliant Lady, after having been told so honestly, and so often of it by the very Woman her self. Our late unhappy Monarch had never trusted the English Clergy, when they preacht up that Non-Resistance, which he must needs see they could never Practice; had his Majesty been screw'd up into this Cogitator, he had presently reflected, that it was against Nature to expect they should stand still, and let him tread upon them: That they should, whatever they had preacht or pretended to, hold open their Throats to have them be cut, and tye their own Hands from resisting the Lord's Anointed. Had some of our Clergy been screw'd in this Engine, they had never turned Martyrs for their Allegiance to the Late King, only for the Lechery of having Dr. S------- in their Company. Had our Merchants been manag'd in this Engine, they had never trusted their Turkey Fleet with a famous Squadron, that took a great deal of care to Convoy them safe into the Enemies Hands. Had some People been in this Engine, when they had made a certain League in the World, in order to make amends for a better made before, they would certainly have consider'd farther, before they had embarkt with a Nation, that are neither fit to go abroad nor stay at Home. As for the Thinking practis'd in Noble Speeches, Occasional Bills, Addressings about Prerogative, Convocation Disputes, Turnings in and Turnings out at Ours, and all the Courts of Christendom, I have nothing to say to it. Had the Duke of Bavaria been in our Engine, he would never have begun a Quarrel, which he knew all the Powers of Europe were concern'd to suppress, and lay all other Business down till it was done.
