From "Naming Day in Eden" (1958) by Noah Jonathan Jacobs
"Adam's bold step towards freedom introduced new features of violence into the world and seriously disturbed the balance between the animal and plant kingdoms. His sudden departure must have been regarded by the others as a breach of loyalty on the part of a degenerate member who had lost his sound animal sense. They classified their poor relation as a zoological freak, a beast with brains, a man fallen from monkeyhood, and then they returned to their sensible round of duties. Naturally they refused to follow him to the perilous fronteir so far removed from corporeal being, except the dog....
The dog is aware of his own worthlessness. Waggish cynical, a slave to wretched odors, he is constantly sniffing about as if he had lost something irrecoverable."
