_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._
