  On the other hand, there is the view that the analysis above (as well as other similar analyses of  factorizability[7])  is immaterial for studying quantum non-locality (Butterfield 1992a, pp. 63-64, Jones and Clifton 1993, Maudlin 1994, pp. 96 and 149) and even misleading (Maudlin 1994, pp. 94-95 and 97-98). On this alternative view, the way to examine the nature of quantum non-locality is to study the ontology postulated by the various interpretations of quantum mechanics and alternative quantum  theories.[8]  In sections 4-7, we shall follow this methodology and discuss the nature of non-locality postulated by several quantum theories. The discussion in these sections will furnish the ground for evaluating the above controversy in section 8.
