" There is a possible slight confusion here that I should eliminate. Robinette (and all the rest of the human race) called these people Heechee. Of course, they didn’t call themselves that, any more than native Americans called themselves Indians or the African Khoi-San tribes called themselves Hottentots and Bushmen. What the Heechee in fact called themselves was the intelligent ones. But that proves little. So does Homo sapiens. "

― Frederik Pohl , Heechee Rendezvous (Heechee Saga, #3)
