Right and wrong exist as conceptions of mind, because there are portions of the universe capable of happiness and misery. Erase sentiency from the universe and you erase the possibility of ethics. Every conscious portion of the universe, therefore, has ethical relations to every other conscious portion (man, woman, worm, Eskimo, oyster, ox), but not to inanimate portions (clod, cabbage, river, rose), because the ones are sentient and the others are not.
