Substance is a subspecies of value. When you reverse the containment process and define substance in terms of value the mystery disappears: substance is a "stable pattern of inorganic values." The problem then disappears. The world of objects and the world of values is unified.
Robert M. PirsigHow are you going to teach virtue if you teach the relativity of all ethical ideas? Virtue, if it implies anything at all, implies an ethical absolute. A person whose idea of what is proper varies from day to day can be admired for his broadmindedness, but not for his virtue.
