it is according to their own Fancies. So proud and presumptuous are many: But they shew thereby rather their weaknesses and follies, then any truth; and all their strict and narrow pryings into the secrets of God, are rather unprofitable, vain and impious, then that they should benefit either themselves, or their neighbour; for do all we can, God will not be perfectly known by any Creature: The truth is, it is a meer impossibility for a finite Creature, to have a perfect Idea of an Infinite Being, as God is; be his Reason never so acute or sharp, yet he cannot penetrate what is Impenetrable, nor comprehend what is Incomprehensible: Wherefore, in my opinion, the best way is humbly to adore what we cannot conceive, and believe as much as God has been pleased to reveal, without any further search; lest we diving too deep, be swallowed up in the bottomless depth of his Infiniteness: Which I wish every one may observe, for the benefit of his own self, and of others, to spend his time in more profitable Studies, then vainly to seek for what cannot be found. And with this hearty wish I conclude, resting, Madam, _Your faithful Friend_ _and Servant._ [1] _Ch._ Of the Image of the Mind. XXI. _MADAM,_ Your _Author_ is so much for Spirits, that he doth not stick to affirm,[1] _That Bodies scarce make up a moity or half part of the world; but Spirits, even by themselves, have or possess their moity, and indeed the whole world._ If he mean bodiless and incorporeal Spirits, I cannot conceive how Spirits can take up any place, for place belongs onely to body, or a corporeal substance, and millions of immaterial Spirits, nay, were their number infinite, cannot possess so much place as a small Pins point, for Incorporeal Spirits possess no place at all: which is the reason, that an Immaterial and a Material Infinite cannot hinder, oppose, or obstruct each other; and such an Infinite, Immaterial Spirit is God alone. But as for Created Immaterial Spirits, as they call them, it may be questioned whether they be Immaterial, or not; for there may be material Spirits as well as immaterial, that is, such pure, subtil and agil substances as cannot be subject to any humane sense, which may be purer and subtiller then the most refined air, or purest light; I call them material spirits, onely for distinctions sake, although it is more proper, to call them material substances: But be it, that there are Immaterial Spirits, yet they are not natural, but supernatural; that is, not substantial parts of Nature; for Nature is material, or corporeal, and so are all her Creatures, and whatsoever is not material is no part of Nature, neither doth it belong any ways to Nature: Wherefore, all that is called Immaterial, is a Natural Nothing, and an Immaterial Natural substance, in my opinion, is _non_-sense: And if you contend with me, that Created Spirits, as good and bad Angels, as also the Immortal Mind of Man, are Immaterial, then I say they are Supernatural; but if you
