Axiom ax-sdo 245

Description: The principle of self-defeating objects. If an object's existence would imply that it doesn't exist -- usually via contradiction -- then it doesn't exist. As a special case, if some tuple's membership in a relation would imply non-membership in that relation, then it's not a member. For a survey of this principle across maths, see [Tao].
