This man that I had was a plain ignorant fellow, and therefore the more likely to tell truth: for your better-bred sort of men are much more curious in their observation, ‘tis true, and discover a great deal more; but then they gloss upon it, and to give the greater weight to what they deliver, and allure your belief, they cannot forbear a little to alter the story; they never represent things to you simply as they are, but rather as they appeared to them, or as they would have them appear to you, and to gain the reputation of men of judgment, and the better to induce your faith, are willing to help out the business with something more than is really true, of their own invention. Now in this case, we should either have a man of irreproachable veracity, or so simple that he has not wherewithal to contrive, and to give a colour of truth to false relations, and who can have no ends in forging an untruth. Such a one was mine; and besides, he has at divers times brought to me several seamen and merchants who at the same time went the same voyage. I shall therefore content myself with his information, without inquiring what the cosmographers say to the business. We should have topographers to trace out to us the particular places where they have been; but for having had this advantage over us, to have seen the Holy Land, they would have the privilege, forsooth, to tell us stories of all the other parts of the world beside. I would have every one write what he knows, and as much as he knows, but no more; and that not in this only but in all other subjects; for such a person may have some particular knowledge and experience of the nature of such a river, or such a fountain, who, as to other things, knows no more than what everybody does, and yet to give a currency to his little pittance of learning, will undertake to write the whole body of physics: a vice from which great inconveniences derive their original.
