 His proof that there must be this intelligible possession and not merely physical possession turns on the application of human choice (6:246). An object of choice is one that some human has the capacity to use as means for various ends or purposes. Rightful possession would be the right to make use of such an object. Suppose that for some particular object, no one is allowed to have rightful possession. This would mean that a usable object would be beyond possible use. But putting an object beyond rightful use when humans have the capacity to use it would “annihilate” the object in a practical respect, treat it as nothing. Kant claims that this is problematic because in a practical respect an object is considered merely as an object of possible choice. This consideration of the mere form alone, the object simply as an object of choice, cannot contain any prohibition of use for an object, for any such prohibition would be freedom limiting itself for no reason. Thus in a practical respect an object cannot be treated as nothing, and so the object must be considered as at least potentially in rightful possession of some human being or other. So all objects within human capacity for use must be subject to rightful or intelligible possession.
