At the base of the construction lies the assumption that the cause of actuality of a property of one of the (as individual considered) entities in the compound system can be actuality of a property of the other one.8 pages; lecture given at the fourth biannual conference of the International Quantum Structures Association, Liptovsky Jan, Slovakia, 1998Quantum PhysicsMathematical PhysicsStructural Characterization of Compoundnesstext
