be the cause of all the most curious varieties and effects in nature: Was not God able to give self-motion as well to a Material, as to an Immaterial Creature, and endow Matter with a self-moving power? I do not say, _Madam_, that Matter hath motion of it self, so, that it is the prime cause and principle of its own self-motion; for that were to make Matter a God, which I am far from believing; but my opinion is, That the self-motion of Matter proceeds from God, as well as the self-motion of an Immaterial Spirit; and that I am of this opinion, the last Chapter of my Book of Philosophy will enform you, where I treat of the Deitical Centre, as the Fountain from whence all things do flow, and which is the supream Cause, Author, Ruler and Governor of all. Perhaps you will say, it is, because I make Matter Eternal. 'Tis true, _Madam_, I do so: but I think Eternity doth not take off the dependance upon God, for God may nevertheless be above Matter, as I have told you before. You may ask me how that can be? I say, As well as any thing else that God can do beyond our understanding: For I do but tell you my opinion, that I think it most probable to be so, but I can give you no Mathematical Demonstrations for it: Onely this I am sure of, That it is not impossible for the Omnipotent God; and he that questions the truth of it, may question Gods Omnipotency. Truly, _Madam_, I wonder how man can say, God is Omnipotent, and can do beyond our Understanding, and yet deny all that he is not able to comprehend with his reason. However, as I said, it is my opinion, That Matter is self-moving by the power of God; Neither can Animadversion, and Perception, as also the variety of Figures, prove, that there must be another external Agent or Power to work all this in Matter; but it proves rather the contrary; for were there no self-motion in Matter, there would be no Perception, nor no variety of Creatures in their Figures, Shapes, Natures, Qualities, Faculties, Proprieties, as also in their Productions, Creations or Generations, Transformations, Compositions, Dissolutions, and the like, as Growth, Maturity, Decay, &c. and for Animals, were not Corporeal Matter self-moving, dividable and composable; there could not be such variety of Passions, Complexions, Humors, Features, Statures, Appetites, Diseases, Infirmities, Youth, Age, &c. Neither would they have any nourishing Food, healing Salves, soveraign Medicines, reviving Cordials, or deadly Poysons. In short, there is so much variety in Nature, proceeding from the self-motion of Matter, as not possible to be numbred, nor thorowly known by any Creature: Wherefore I should labour in vain, if I endeavoured to express any more thereof; and this is the cause that I break off here, and onely subscribe my self, Madam, _Your faithful Friend_ _and Servant._ XXIII. _MADAM,_
