|Ontological Commitment: A theory is bound to the acceptance of objects if it were wrong without the existence of these objects. It may be, however, that parts of the theory do not have to contain the object, then the ontological commitment for the whole theory is omitted. (See H. Lauener Quine, 1982, p. 130).|
