Lumen de Lumine

I would not Eugenius, have thee ignorant of the Unitie, and Concentration of Sciences. In the past, and more Knowing years of the world, when Magic was better, and more generally understood, the Professors of this Art divided it into three parts, Elementall, Cœlestiall, and Spirituall. The Elementall part contained all the Secrets of Physic, the Cœlestiall those of Astrologie, and the Spirituall those of Divinitie. Every one of these by it self was but a Branch or Lim, but being united all Three, they were the Pandects of the Science. Now in these thy days there is no man can shew thee any reall Physic, or Astrologie, neither have they any more, than a Tong-and-Book Divinitie. The reason of it is this; In Process of time these three Sciences (which work no wonders without a mutuall essentiall Union) were by mis-interpretation dismembred, and set apart, so that every one of them was held to be a Facultie by it self. Now God had united these Three in one Naturall Subject, but man hee separated them, and placed them in no Subject, but in his own Brain, there they remained in words and fansie, not in Substantiall Elements, and Veritie. In this state the Sciences were dead and Ineffectuall: they yeelded nothing but Noyse, for they were separated: As if thou should'st dismember a Man, and then expect some one part of him should performe those Actions, which the whole did, when he was alive.
