The Houyhnhnm’s notion of truth and falsehood. The author’s discourse disapproved by his master. The author gives a more particular account of himself, and the accidents of his voyage.

My master heard me with great appearances of uneasiness in his countenance; because doubting, or not believing, are so little known in this country, that the inhabitants cannot tell how to behave themselves under such circumstances. And I remember, in frequent discourses with my master concerning the nature of manhood in other parts of the world, having occasion to talk of lying and false representation, it was with much difficulty that he comprehended what I meant, although he had otherwise a most acute judgment. For he argued thus: “that the use of speech was to make us understand one another, and to receive information of facts; now, if any one said the thing which was not, these ends were defeated, because I cannot properly be said to understand him; and I am so far from receiving information, that he leaves me worse than in ignorance; for I am led to believe a thing black, when it is white, and short, when it is long.” And these were all the notions he had concerning that faculty of lying, so perfectly well understood, and so universally practised, among human creatures.
