In the second Treatise I have demonstrated the manner of distilling subtil, volatile, sulphureous spirits, _viz._ of common salt, vitriol, allome, nitre, sulphur, antimony, and other salts of minerals, and metals, and their vertues, and intrinsecal properties, now also I will shew their extrinsecal use, as they are to be mixed with waters for Baths. The vertues therefore of Baths proceed not from insipid water, but from those most subtile, volatile, sulphureous, and salt spirits; but these being of themselves not mixed with water unfit for Baths, to be used for recovering of health, by reason of their too great heat, and subtilty; the most high God hath revealed to us unworthy and ungrateful men his fatherly providence shewing to us by nature the use of them, and the manner of using of them for the taking away of diseases; which (nature) being never idle, works uncessantly, and like a handmaid executes the will of God, by shewing to us the various kinds of distillations, transmutations, and generations. From which teacher we must learn all arts and sciences, seeking a certain, and infallible information, as it were out of a book writ with a divine hand, and filled with innumerable wonders, and secrets. And this is a far certainer knowledg then that empty, and imaginary Philosophy of those vulgar disputing Philosophers. Dost thou think that that true Philosophy can be sold for a hundred Royals? How can any one judge of things hid in the earth, who is willfully blind in things exposed to the light of the Sun, hating knowledge? I wish knowledge were sutable to the name: how can any one that is ignorant of the nature of fire, know how to work by fire? fire discovers many things, in which you may as in a glass see things that are hid; The fire shews to us how every thing, waters, salt, minerals, and metals, together with other innumerable things are generated in the bowels of the earth by the reflexion of that central, and astral fire: for without the knowledge of fire all nature remains vailed, and occult. Fire (always had in great esteem by Philosophers) is the key for the unlocking of the greatest secrets, and to speak in a word, he that is ignorant of fire is ignorant of nature with her fruits, and he hath nothing, but what he hath read, or heard, which oftentimes is false, according to that; _He easily speaks untruths that speaks what he hath heard_. He that is ignorant knows not how to discern betwixt the truth and falshood, but takes the one for the other. I pray thee, thou that art so credulous, dost thou think that thy teacher writ his books from experience, or from reading other Authors? May they not be corrupted and sophisticated by antiquity, and frequent description? Also dost thou understand the true, and genuine sense of them? It is better to know, than to think; for many are seduced by opinions, and many are deceived by faith that is without knowledge.
