pure and simple corporeal substance; and what Man names impure dregs and filths, these are onely irregular and cross motions of that matter, in respect to the nature of such or such a figure; or such motions as are not agreeable and sympathetical to our Passions, Humors, Appetites, and the like. Concerning the Contrarieties, Differences and Wars in Nature, which your _Author_ denies, I have spoken thereof already, and though he endeavours in a long discourse to prove, that there is no War in nature; yet, in my opinion, it is to little purpose, and it makes but a war in the thoughts of the Reader; I know not what it did in his own. But I observe he appeals often to Divinity to bear him up in Natural Philosophy; but how the Church doth approve his Interpretations of the Scripture, I know not: Wherefore I will not meddle with them, lest I offend the Truth of the Divine Scripture, wherein I desire to submit to the Judgment of the Church, which is much wiser then I, or any single Person can be. However, for all what your _Author_ says, I do nevertheless verily believe, there is a war between Natural motions: For example; between the Regular motions of Health, and the Irregular motions of Sickness; and that things applied do oftentimes give assistance to one side or other, but many times in the conflict, the applied remedies are destroyed, and sometimes they are forced to be Neutrals: Wherefore though the nature of Infinite Matter is simple, and knows of no discord, yet her actions may be cross and opposite: the truth is, Nature could never make such variety, did her actions never oppose each other, but live in a constant Peace and Unity. And thus leaving them to agree, I am confident your _Ladiship_ and I shall never disagree; for as long as my life doth last, I shall always prove, Madam, _Your constant Friend,_ _and faithful Servant._ [1] _Ch._ The Fiction of Elementary Complexions and Mixtures.
