 Questions arise about the relationships between (1)–(5). (1) and (5) are similar in letting the question of an entity’s neutrality be settled by its intrinsic nature. (2)–(4) answer this question by looking at the relationships of a given entity to other things: to the nature of larger groups of entities of which the given entity is/can be a member: are these groups mental or physical? Or by looking to the kinds of laws that govern the entity in question: are the laws mental or physical? If one is inclined to think that neutrality is a matter of intrinsic nature alone, (2)–(4) will seem misguided. (2)–(4) still might have a place as epistemic criteria—as ways of finding out whether a given entity is neutral. The friends of (1) and (5) can agree that a given entity’s ability to actually or possibly belong to a certain group, or to be governed by certain laws, is due solely to its intrinsic nature. Their disagreement concerns only the question whether this ability is conferred on that entity by its being both mental and physical or neither mental or nor physical. In either case (2)–(4) can only be used to discover which things are the neutral entities.
