There is abundance of knowledge, yet but little truth known. The generality of our knowledg is but as Castles in the aire, or groundlesse fancies. I know but two ways that are ordained for the getting of wisdome, _viz._ the book of God, and of Nature; and these also, but as they are read with reason. Many look upon the former as a thing below them, upon the latter as a ground of Atheisme, and therefore neglect both. It is my judgement, that as to search the Scriptures is most necessary, so without reason it is impossible. Faith without reason is but implicite. If _I_ cannot understand by reason how every thing is, yet _I_ wil see some reason that a thing is so, before _I_ beleeve it to be so. I will ground my beleeving of the Scripture upon reason, I will improve my reason by Philosophy. How shall we convince gain-sayers of the truth of the Scriptures, but by principles of Reason? When God made Man after his own image, How was that? But by making him a rational creature? Men therfore that lay aside Reason in the reading of sacred mysteries, do but un-man themselves, and become further involved in a Labyrinth of errors. Hence it is that their Religion is degenerated into irrationall notions. Now to say, that pure Philosophy is true Divinity, will haply bee a paradox, yet if any one should affirm it, he would not be heterodox. When _Job_ had been a long time justifying himselfe against God, which I conceive was by reason of his ignorance of God, and himselfe; God undertakes to convince him of his errour by the principles of Nature, and to bring him to the knowledge of both: as you may see at large, _Job_ 38. Can any deny that _Hermes_, _Plato_, _Aristotle_ (though pure Naturalists) were not most deep Divines? Doe not all grant that the two first cha. of _Gen._ are true Divinity? I dare also affirm that they are the most deep and the truest Philosophy. Yea, they are the ground, and sum of all Divinity, and Philosophy: and if rightly understood, will teach thee more knowledge of God, and thy selfe, then all the books in the world besides. Now for the better understanding of them, make use of most profound _Sandivogius_ the author of the first of the ensuing Treatises, as the best Expositor of them: in that treatise of his thou shalt see the mystery of the Deity, & Nature unfolded, even to admiration: as to see what that light, and fire is which is the throne of Gods Majesty. How he is in the heaven most gloriously, & in the creatures providentially. How he is the life of that universall Spirit which is diffused through the whole world. What that Spirit of his is that moved upon the Waters. What those Waters are which are above the Firmament, and which are under the Firmament. What that Sperm and Seed was which God put into all creatures by which they should be multiplyed. The true manner of Mans Creation, and his degenerating into Mortality. The true nature of the Garden of _Eden_, or Paradise. Also
