1. Those that affirm that the Devil did or can produce such strange effects, do also acknowledge, that what he performeth in natural and elementary Bodies, is done by applying natural agents to natural and fit patients, which do truly bring to pass such strange effects, and that he doth no more, but only make the local application of them. From whence it must necessarily follow that the effects flow from natural agents, and so no causality at all can be ascribed unto him, except that fictitious one of being _causa sine qua non_, which is as much as no cause. And besides that, there is no proof that he maketh this local application; for if he be incorporeal, then it is simply impossible that he should perform any such matter; and however, a man by natural power and means, if he know the fit and apt actives and passives, may perform them himself, and so his assistance is needless; and we have never yet met with any argument that bore any convincing force that might induce us to believe that he is so great a Naturalist. [Sidenote: _Argum. 2._] [Sidenote: _De secret. oper. Art. & natur._ _c._ 5.] [Sidenote: Gen. 30. 37, 38, 39. _&c._] 2. There are many persons that think themselves no mean sharers in the most sorts of learning, and others that are very strait laced in their pretended zeal for godliness, and in detesting the works of Satan, that even startle and shew an abhorrency at the word Magick, if it be but once named, as though there were no Magick but what is diabolical, or that which they call diabolical were any other way evil but only in the end and use: for there are many plants and minerals, that though poysonous, are yet notwithstanding good in respect of their Creation, and the good uses that may be made of them, as to kill noxious animals that are hurtful unto man. But if any force of malice and wickedness should use them to poyson and destroy Men and Women, it were wicked and diabolical in the end and use, yet were the means lawful and natural. So whatsoever the Devil may do by wicked Men, his instruments, in leading and drawing them to make use of the great _magnalia naturæ_, to work strange wonders by, thereby to confirm Idolatry and Superstition, or to resist the truth and such devilish ends, though the end and use may be wicked and diabolical, yet the efficient cause is natural and lawful. And therefore we can find no other ground or reason of dividing Magick into natural and Diabolical, but only that they differ in the end and use: for otherwise they both work by a natural agency and means, seeing the Devil can do nothing above or contrary to that course that God hath set in nature. Therefore may men do without the aid of Devils whatsoever they can do, seeing they have no advantage over us, but operate only by applying active things to passive, like as Men do: And therefore said that most learned Philosopher, Chymist and Mathematician, our Countreyman _Roger Bacon_, excellent well in these words: _non igitur
