graver Philosophers; tho' 'tis certain no one ever met with any such absurd Creature, or convers'd with a Man, who had no Opinion or Principle concerning any Subject, either of Action or Speculation. This begets a very natural Question; What is meant by a Sceptic? And how far it is possible to push these philosophical Principles of Doubt and Uncertainty?
There is a Species of Scepticism, antecedent to all Study and Philosophy, which is much inculcated by Des Cartes and others, as a sovereign Preservative against Error and precipitate Judgment. It recommends an universal Doubt, not only of all our former Opinions and Principles, but also of our very Faculties; of whose Veracity, say they, we must assure ourselves, by a Chain of Reasoning, deduc'd from some original Principle, which cannot possibly be fallacious or deceitful. But neither is there any such original Principle, which has a Prerogative above others, that are self-evident and convincing: Or if there were, could we advance a Step beyond it, but by the Use of those very Faculties, of which we are suppos'd to be already diffident. The Cartesian Doubt, therefore, were it ever possible, to be attain'd by any human Creature (as it plainly is not) would be altogether incurable; and no Reasoning could ever bring us to a State of Assurance and Conviction upon any Subject.
