The third Direction.—The true one is of a larger Letter than the counterfeit ones, which are in Twelves, &c., of the Letter small Bibles used to be printed on. I shall now speak something of the book itself.
All other Authors that have written of the nature of Herbs, give not a bit of reason why such an Herb was appropriated to such a part of the body, nor why it cured such a disease. Truly my own body being sickly, brought me easily into a capacity, to know that health was the greatest of all earthly blessings, and truly he was never sick that doth not believe it. Then I considered that all medicines were compounded of Herbs, Roots, Flowers, Seeds, &c., and this first set me to work in studying the nature of simples, most of which I knew by sight before; and indeed all the Authors I could read gave me but little satisfaction in this particular, or none at all. I cannot build my faith upon Authors’ words, nor believe a thing because they say it, and could wish every body were of my mind in this,—to labour to be able to give a reason for every thing they say or do. They say Reason makes a man differ from a Beast; if that be true, pray what are they that, instead of reason for their judgment, quote old Authors? Perhaps their authors knew a reason for what they wrote, perhaps they did not; what is that to us? Do we know it? Truly in writing this work first, to satisfy myself, I drew out all the virtues of the vulgar or common Herbs, Plants, and Trees, &c., out of the best or most approved authors I had, or could get; and having done so, I set myself to study the reason of them. I knew well enough the whole world, and every thing in it, was formed of a composition of contrary elements, and in such a harmony as must needs show the wisdom and power of a great God. I knew as well this Creation, though thus composed of contraries, was one united body, and man an epitome of it: I knew those various affections in man, in respect of sickness and health, were caused naturally (though God may have other ends best known to himself) by the various operations of the Microcosm; and I could not be ignorant, that as the cause is, so must the cure be; and therefore he that would know the reason of the operation of the Herbs, must look up as high as the Stars, astrologically. I always found the disease vary according to the various motions of the Stars; and this is enough, one would think, to teach a man by the effect where the cause lies. Then to find out the reason of the operation of Herbs, Plants, &c., by the Stars went I; and herein I could find but few authors, but those as full of nonsense and contradiction as an egg is full of meat. This not being pleasing, and less profitable to me, I consulted with my two brothers, Dr. Reason and Dr. Experience, and took a voyage to visit my mother Nature, by whose advice, together with the help of Dr. Diligence, I at last obtained my desire; and, being warned by Mr. Honesty, a stranger in our days, to publish it to the world, I have done it.
But you will say, What need I have written on this Subject, seeing so many famous and learned men have written so much of it in the English Tongue, much more than I have done?
To this I answer, neither Gerrard nor Parkinson, or any that ever wrote in the like nature, ever gave one wise reason for what they wrote, and so did nothing else but train up young novices in Physic in the School of tradition, and teach them just as a parrot is taught to speak; an Author says so, therefore it is true; and if all that Authors say be true, why do they contradict one another? But in mine, if you view it with the eye of reason, you shall see a reason for everything that is written, whereby you may find the very ground and foundation of Physic; you may know what you do, and wherefore you do it; and this shall call me Father, it being (that I know of) never done in the world before.
I have now but two things to write, and then I have done.
- 1. What the profit and benefit of this Work is.
- 2. Instructions in the use of it.
1. The profit and benefit arising from it, or that may occur to a wise man from it are many; so many that should I sum up all the particulars, my Epistle would be as big as my Book; I shall quote some few general heads.
First. The admirable Harmony of the Creation is herein seen, in the influence of Stars upon Herbs and the Body of Man, how one part of the Creation is subservient to another, and all for the use of Man, whereby the infinite power and wisdom of God in the creation appear; and if I do not admire at the simplicity of the Ranters, never trust me; who but viewing the Creation can hold such a sottish opinion, as that it was from eternity, when the mysteries of it are so clear to every eye? but that Scripture shall be verified to them, Rom. i. 20: “The invisible things of him from the Creation of the World are clearly seen, being understood by the things that are made, even his Eternal Power and Godhead; so that they are without excuse.”—And a Poet could teach them a better lesson;
“Because out of thy thoughts God shall not pass,
“His image stamped is on every grass.”
