Abstract
Yet this widespread agreement as to the contingency of fact conceals an important possibility of disagreement. For there is a common assumption by which the doctrine of the exclusiveness of factual truths is trivialized. This is the assumption that the excluded alternative can be merely negative. Thus: there are elephants, there might have been no elephants; there is a world, there might have been no world. What the positive fact necessarily excludes, then, is only a privation: in short it may exclude literally nothing. But to exclude nothing is not really, I suggest, to exclude. Real transactions are not concerned with non-entity, and exclusion is in some sense a real transaction. If I am just here, I prevent you from being here. If elephants exist, then, in certain portions of the world at a given moment, other large animals cannot exist, for the space they might occupy is otherwise occupied. The non-being of wild elephants in North America is a partly positive fact, for it means that every portion of the land surface of that continent is covered either by some solid object different from an elephant, or by empty air.
