4. Some say they cannot recede from the opinions of their Predecessors, because it would be a shame and disgrace unto them. But that which we call shame and disgrace consists in the opinion of others, and we ought not to receive errour, or reject truth, by reason of the censures or opinions of others: _Si de veritate scandalum sumitur, utilius permittitur nasci scandalum, quàm veritas relinquatur_. And to leave an errour to entertain truth, is so far from being a shame and a disgrace, that there cannot be a greater honour or glory: for _errare humanum est, sed in errore perseverare belluinum ac diabolicum est_. [Sidenote: _Rule 4._] 4. Those effects that seem strange and wonderful, either in respect of Art or Nature, require much diligence truly to discover and find out their causes; and we ought not rashly to attribute those effects to the Devil, whose causes are latent or unknown unto us: and that for these grounds. [Sidenote: _De Inject. mater. pag. 597._] [Sidenote: _Ibid. pag. 598._] 1. It hath been common almost in all Ages, not only for the vulgar, but also for the whole rabble of Demonographers and Witchmongers to ascribe those strange and wonderful effects, whether arising from Art or Nature, unto the worst of Gods Creatures, if they did not themselves understand their causes, and to censure the Authors that writ of them, as Conjurers and Magicians, as I have made manifest in my former Instances, and might be further made good and illustrated by the effects of healing by the Weapon-salve, the Sympathetick Powder, the Curing of divers Diseases by Appensions, Amulets, or by Transplantation, and many other most admirable effects both of Art and Nature, which by these self-conceited Ignorants are all thrown upon the Devils back, and he made the Author and effector of them, as though he had a kind of omnipotent power: of which the learned Philosopher and Physician _Van Helmont_ gives us this account: “_Credo equidem cum pietate pugnare, si Diabolo tribuatur potestas naturam superans. Verum naturæ ignari præsumunt se naturæ secretarios per librorum lectionem: quicquid autem ipsos latet, vel adynaton, vel falsum, vel præstigiosum, atq; diabolicum esto._” And a little after he adds this: “_Pigritiæ saltem enim immensæ inventum fuit, omnia in Diabolum retulisse quæ non capimus, nec velim Diabolum invocatum, ut nostris satisfaciat quæstionibus per temerariam potestatum attributionem._”
