But you may say, Purity belongs onely to natural things, and none but natural bodies can be said purified, but God exceeds all Purity. 'Tis true: But if there were infinite degrees of Purity in Matter, Matter might at last become Immaterial, and so from an Infinite Material turn to an Infinite Immaterial, and from Nature to be God: A great, but an impossible Change. For I do verily believe, that there can be but one Omnipotent God, and he cannot admit of addition, or diminution; and that which is Material cannot be Immaterial, and what is Immaterial cannot become Material, I mean, so, as to change their natures; for Nature is what God was pleased she should be; and will be what she was, until God be pleased to make her otherwise. Wherefore there can be no new Creation of matter, motion, or figure; nor any annihilation of any matter, motion, or figure in Nature, unless God do create a new Nature: For the changing of Matter into several particular Figures, doth not prove an annihilation of particular Figures; nor the cessation of particular Motions an annihilation of them: Neither doth the variation of the Onely Matter produce an annihilation of any part of Matter, nor the variation of figures and motions of Matter cause an alteration in the nature of Onely Matter: Wherefore there cannot be new Lives, Souls or Bodies in Nature; for, could there be any thing new in Nature, or any thing annihilated, there would not be any stability in Nature, as a continuance of every kind and sort of Creatures, but there would be a confusion between the new and old matter, motions, and figures, as between old and new Nature; In truth, it would be like new Wine in old Vessels, by which all would break into disorder. Neither can supernatural and natural effects be mixt together, no more then material and immaterial things or beings: Therefore it is probable, God has ordained Nature to work in her self by his Leave, Will, and Free Gift. But there have been, and are still strange and erroneous Opinions, and great differences amongst Natural Philosophers, concerning the Principles of Natural things; some will have them _Atoms_, others will have the first Principles to be _Salt, Sulphur_ and _Mercury_; some will have them to be the four Elements, as _Fire, Air, Water,_ and _Earth_; and others will have but one of these Elements also some will have _Gas_ and _Blas, Ferments, Ideas_ and the like; but what they believe to be Principles and Causes of natural things, are onely Effects; for in all Probability it appears to humane sense and reason, that the cause of every particular material Creature is the onely and Infinite Matter, which has Motions and Figures inseparably united; for Matter, Motion and Figure, are but one thing, individable in its Nature. And as for Immaterial Spirits, there is surely no such thing in Infinite Nature, to wit, so as to be Parts of Nature; for Nature is altogether Material, but this opinion
