Jonathan Swift,
Gulliver's Travels
(1726)
“ 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. ”
