PREFACE.
T being usual for Authors, in Prefaces, to render an Account of the Occasion which gave Birth to their Writings, and to acquaint the Reader with the Design and Scope of their Discourses; I thought it convenient to continue a Custom approved by many illustrious Examples.
The Motive of publishing this Tract, is not the Intercession of Friends, for none had ever the View of any Part of it; and that it is not Design of Applause that has engaged me in this Undertaking, the Care I have had to conceal my Name will, I suppose, free me from such Suspicion: the chief Inducement proceeds from an Inclination to Mankind, to instruct them to preserve and prolong their Lives, thereby to prevent them from using fraudulent Quack Medicines (which are now become so universally vendible amongst them) or advising with such as are wholly ignorant; and I should think my self sufficiently rewarded for my Pains, if I could arrive to the Point of reforming the Abuses of the present, and restoring the Simplicity of the ancient Practice, by laying open to the World my Observations of the pretended and fallacious Methodus Medendi, and the Insignificancy of a great Part of their Materia Medica.
And here I will particularly address my self to all those Persons concern’d with me, who are the People or Patients; and the Physicians with their Followers, the Chirurgeons and Apothecaries: This Discourse is chiefly intended for the first, it being they who are most highly injured by the unwarrantable Practices of those we have therein accused; for although many understanding Persons among the People are sufficiently satisfied of the Abuses we have mentioned; and that it is of absolute Necessity some Reformation should be made: Yet all are not thus perswaded; for we may daily observe, that many who are less discerning, being deceiv’d by an imaginary Good, covet their own Ruin; and unless they be given to understand which is the Evil, and which is the Good, by Persons they have Reason to confide in, they must necessarily run much Hazard.
I have here endeavoured to undeceive them; which I should dispair of, did I only foresee Inconveniencies afar off (the Vulgar being led by Sense, and not by probable Conjectures); but since they do now actually labour under many, and those obvious, Inconveniencies, how short sover their sight be, the Senses of Feeling being no less acute in them than in others, I persuade my self, they will readily assent to those Truths I have largely discovered.
And here must I venture through all the Barricadoes and the Fortifications of popular Resentment; but Satires, like Incision, become necessary when the Humour rankles, and the Wound threatens Mortification; when Advice ceases to work; when Loss, Experience, and Disaster will not convince, then Satire reforms, by making the Error we embrace ridiculous: Shame works to make us forsake a Thing, which Instruction augments, or Persuasion could have no Effect upon.
Many and great Abuses, and of the last Importance to the People, have urged my Duty and demanded my Assistance; and if in my Essay on Health, I do persuade my Reader to the Regimen I have here laid down, he may assure himself of that Golden Panacea, that Elixir Salutis, at no other Charge but in cura seipsum.
It would by many be expected, that I should make an Apology for the great Liberties I have taken in my general Treatment of the whole Faculty; in which I claim the allow’d Exception, that there are some few very Eminent, and worthy of the first Honours and Dignity of Physick, and who by their unwearied Labour of Body and Application of Mind, have run through the Courses of Anatomy, Botany, Chymistry, and Galenick Pharmacy, and no less acquainted with the Virtues, Faults, and Preparations, Compositions and Doses of Vegetables, Animals, Minerals, and all the Shop Medicines.
