The Devil being thus reduc'd to act upon Mankind by Stratagem only, it remains to enquire how he performs, and which way he directs his Attacks; the Faculties of Man are a kind of a Garrison in a strong Castle, which as they defend it on the one hand under the Command of the reasoning Power of Man's Soul, so they are prescribed on the other hand, and can't sally out without Leave; for the Governor of a Fort does not permit his Soldiers to hold any Correspondence with the Enemy, without special Order and Direction. Now the great Enquiry before us is, How comes the DEVIL to a Parley with us? how does he converse with our Senses, and with the Understanding? How does he reach us, which way does he come at the Affections, and which way does he move the Passions? 'Tis a little difficult to discover this treasonable Correspondence, and that Difficulty is indeed the _Devil_'s Advantage, and, for ought I see, the chief Advantage he has over Mankind. It is also a great Enquiry here, whether the _Devil_ knows our Thoughts or no? If I may give my Opinion, I am with the negative; I deny that he knows any thing of our Thoughts, except of those Thoughts which he puts us upon thinking, for I will not doubt but he has the Art to inject Thoughts, and to revive dormant Thoughts in us: It is not so wild a Scheme as some take it to be, that Mr. _Milton_ lays down, to represent the _Devil_ injecting corrupt Desires and wandring Thoughts into the Head of _Eve_, by Dreams, and that he brought her to Dream whatever he put into her Thoughts, by whispering to her vocally when she was asleep; and to this End, he imagines the DEVIL laying himself close to her Ear, in the Shape of a Toad, when she was fall asleep; I say, this is not so wild a Scheme, seeing even now, if you can whisper any thing close to the Ear of a Person in a deep Sleep, so as to speak distinctly to the Person, and yet not awaken him, as has been frequently tried, the Person sleeping shall dream distinctly of what you say to him; nay, shall dream the very Words you say. We have then no more to ask, but how the DEVIL can convey himself to the Ear of a sleeping Person, and it is granted then that he may have Power to make us dream what he pleases: But this is not all, for if he can so forcibly, by his invisible Application, cause us to dream, what he pleases, why can he not with the same Facility prompt our Thoughts, whether sleeping or waking? To dream, is nothing else but to think sleeping; and we have abundance of deep-headed Gentlemen among us, who give us ample Testimony that they dream waking.
