As the Being, Nature, and Scituation of humane Soul is thus Spherically and Mathematically discover'd, I could not find any Second Thoughts about it in all their Books, whether of their own Composition or by Translation; for it was a General received Notion, That there could not be a greater Absurdity in humane Knowledge, than to imploy the Thoughts in Questioning, what is as plainly known by its Consequences, as if seen with the Eye; and that to doubt the Being or Extent of the Soul's Operation, is to imploy her against her self; and therefore, when I began to argue with my Old Philosopher, against the Materiality and Immortality of this Mystery we call Soul, he laught at me, and told me, he found we had none of their Glasses in our World; and bid me send all our Scepticks, Soul-Sleepers, our Cowards, Bakers, Kings and Bakewells, up to him into the Moon, if they wanted Demonstrations; where, by the help of their Engines, they would make it plain to them, that the Great Eye being one vast Intellect, Infinite and Eternal, all Inferior Life is a Degree of himself, and as exactly represents him as one little Flame the whole Mass of Fire; That it is therefore uncapable of Dissolution, being like its Original in Duration, as well as in its Powers and Faculties, but that it goes and returns by Emission, Regression, as the Great Eye governs and determines; and this was plainly made out, by the Figure I had seen it in, viz. an Eye, the exact Image of its Maker: 'Tis true, it was darkened by Ignorance, Folly and Crime, and therefore oblig'd to wear Spectacles; but tho' these were Defects or Interruptions in its Operation, they were none in its Nature; which as it had its immediate Efflux from the Great Eye, and its return to him must partake of himself, and could not but be of a Quality uncomatable, by Casualty or Death. From this Discourse we the more willingly adjourned our present Thoughts, I being clearly convinced of the Matter; and as for our Learned Doctors, with their Second and Third Thoughts, I told him I would recommend them to the Man in the Moon for their farther Illumination, which if they refuse to accept, it was but just they should remain in a Wood, where they are, and are like to be, puzzling themselves about Demonstrations, squaring of Circles, and converting oblique into right Angles, to bring out a Mathematical Clock-Work Soul, that will go till the Weight is down, and then stand still till they know not who must wind it up again. However, I cannot pass over a very strange and extraordinary piece of Art which this Old Gentleman inform'd me of, and that was an Engine to screw a Man into himself: Perhaps our Country-men may be at some Difficulty to comprehend these things by my dull Description; and to such I cannot but recommend, a Journey in my Engine to the Moon.
