5. There are many various things, of divers Natures, prescribed by Physicians, and others, as Washes to preserve the Teeth and Gums; but most of them, if not all, to little or no purpose, as daily Experience teaches: For, all high, sharp Salts, and things of a sour or keen nature, do rather cause the Teeth to perish, than the contrary; as do all hot Spirits, be they what they will: Many have destroyed their Teeth by the frequent use of such things, and it hath hardly ever been known that any such things have ever cured or prevented the aking Pains of the Teeth, but Water only. Many Examples I could mention, if it were convenient. Physicians, and others, do daily prescribe such things for the Cure and Prevention of this Disease of the Teeth, which most of them do know by experience can do no good, but rather the contrary: But when People come to them, they must give them something for their Money; for Interest and Ignorance have more affinity with this sort of People, than Vertue, and the true Knowledge of the Nature of Things. Most certain it is, That the Shepherd and Husbandman do know far better how to prepare the Meat for their Cattel, and also how to preserve them from Disorders, than many Physicians do their Food or Physick: and a Man shall understand more by conversing with some of this sort of People, than with the Learned: For the Shepherd and Husbandman understand something of Nature; but most of the Learned are departed from the simple Ways of God in Nature, putting out their own Eyes, and then boasting what Wonders they can see with other Mens: They have invented many Words to hide the Truth from the Unlearned, that they may get the greater esteem. This hath chiefly been done to advance Pride and Interest; so that the Divine Eye is departed from many of them, who never make any Inspexion into the true Nature of Things, being contented to take other Mens Words, let it be right or wrong, as long as they have Authority and Law on their sides, wherefore should they trouble their weak Heads?
