houhyhynm
Horse like creatures in the book "Gulliver's Travels" that,in their world replace humans as a dominant species. Houhyhynms talk, but only say things that are true and logical. In this world, there are also beings called Yahoos who are human like. They, however, are the slaves of this world.
The houhyhynms were much more human than most of the men I had met.
