It is true, the Candles burn thus in Mines and Vaults, and damp Places; and 'tis as true that they will do so upon Occasion of very damp, stormy and moist Air, when an extraordinary Quantity of Vapours are supposed to be dispers'd abroad, as was the Case when this happen'd; and if there was any Thing of that in it on that _Monday_ Night, the Candles might, perhaps, burn blue upon that Occasion; but that the _Devil_ was abroad upon any extraordinary Business that Night, that I cannot grant, unless I have some better Testimony than the _old Lady_ that heard the Footman's out-cry but by halves, or than Mrs. _Betty_, who first fancied the Candles _burnt blue_; so I must suspend my Judgment till I hear farther. This Story however may solve a great many of those Things which pass for Apparitions in the World, and which are laid to the Devil's Charge, tho' he really may know nothing of the Matter; and this would bring me to defend _Satan_ in many Things, wherein he may truly be said to suffer wrongfully; and if I thought it would oblige him, I might say something to his Advantage this Way; however, I'll venture a Word or two for an injur'd _Devil_, take it as you will. First, it is certain, that as this Invisibility of the _Devil_ is very much to our Prejudice, so the Doctrine of his Visibility is a great Prejudice to him, as we make Use of it. By his Invisibility he is certainly vested with infinite Advantages against us; while he can be present with us, and we know nothing of the Matter, he informs himself of all our Measures, and arms himself in the best and most suitable manner to injure and assault us, as he can counteract all our secret concerted Designs, disappoint all our Schemes, and except when Heaven apparently concerns it self to over-rule him, can defeat all our Enterprizes, break all our Measures, and do us Mischief in almost every Part of our Life, and all this, because we are not privy to all his Motions, as he is to ours. But now for his Visibility and his real Appearance in the World, and particularly among his Disciples and Emissaries, such as Witches and Wizards, Demonaists, and the like: Here, I think Satan has a great deal of Loss, suffers manifest Injury, and has great Injustice done him; and, that therefore I ought to clear this Matter up a little, if it be possible, to do Justice to Satan, and set Matters right in the World about him, according to that useful old Maxim of setting the Saddle upon the right Horse, or _giving the_ Devil _his due_.
