    "abstract": "Various topics concerning the entanglement of composite quantum systems are\nconsidered with particular emphasis concerning the strict relations of such a\nproblem with the one of attributing objective properties to the constituents.\nMost of the paper deals with composite systems in pure states. After a detailed\ndiscussion and a precise formal analysis of the case of systems of\ndistinguishable particles, the problems of entanglement and the one of the\nproperties of subsystems of systems of identical particles are thourougly\ndiscussed. This part is the most interesting and new and it focuses various\nsubtle questions which have never been adequately discussed in the literature.\nSome inappropriate assertions which appeared in recent papers are analyzed. The\nrelations of the main subject of the paper with the nonlocal aspects of quantum\nmechanics, as well as with the possibility of deriving Bell\u0027s inequality are\nalso considered.",
