"If the censure of the Yahoos could any way affect me, I should have great reason to complain, that some of them are so bold as to think my book of travels a mere fiction out of mine own brain, and have gone so far as to drop hints, that the Houyhnhnms and Yahoos have no more existence than the inhabitants of Utopia. Indeed I must confess, that as to the people of Lilliput, Brobdingrag (for so the word should have been spelt, and not erroneously Brobdingnag), and Laputa, I have never yet heard of any Yahoo so presumptuous as to dispute their being, or the facts I have related concerning them; because the truth immediately strikes every reader with conviction. And is there less probability in my account of the Houyhnhnms or Yahoos, when it is manifest as to the latter, there are so many thousands even in this country, who only differ from their brother brutes in Houyhnhnmland, because they use a sort of jabber, and do not go naked? I wrote for their amendment, and not their approbation. The united praise of the whole race would be of less consequence to me, than the neighing of those two degenerate Houyhnhnms I keep in my stable; because from these, degenerate as they are, I still improve in some virtues without any mixture of vice."
