Object-relating can be described in terms of the experience of the subject. Description of object-usage involves consideration of the nature of the object. I am offering for discussion the reasons why, in my opinion, a capacity to use an object is more sophisticated than a capacity to relate to objects; and relating may be to a subjective object, but usage implies that the object is part of external reality.

This sequence can be observed: (1) Subject relates to object. (2) Object is in process of being found instead of placed by the subject in the world. (3) Subject destroys object. (4) Object survives destruction. (5) Subject can use object.
