I am a realist. Tario is an etherealist. “The etherealists maintain that there is no such thing as matter—that all is mind. They say that none of us exists, except in the imagination of his fellows, other than as an intangible, invisible mentality. “According to Tario, it is but necessary that we all unite in imagining that there are no dead Torquasians beneath our walls, and there will be none, nor any need of scavenging banths.” “You, then, do not hold Tario’s beliefs?” asked Carthoris. “In part only,” replied the Lotharian. “I believe, in fact I know, that there are some truly ethereal creatures.

Upon such, then, may you exist.” “But I thought you were a realist,” exclaimed Carthoris. “Indeed,” cried Jav, “what more realistic than this bounteous feast? It is just here that we differ most from the etherealists. They claim that it is unnecessary to imagine food; but we have found that for the maintenance of life we must thrice daily sit down to hearty
