However, Kleinians also utilize Freud's first conception of splitting, to explain the way "In a related process of splitting, the person divides his own self. This is called 'splitting of the ego'." Indeed, Klein herself maintained that "the ego is incapable of splitting the object—internal or external—without a corresponding splitting taking place within the ego". Arguably at least, by this point "the idea of splitting does not carry the same meaning for Freud and for Klein": for the former, "the ego finds itself 'passively' split, as it were. For Klein and the post-Kleinians, on the other hand, splitting is an 'active' defence mechanism". As a result, by the close of the century "four kinds of splitting can be clearly identified, among many other possibilities" for post-Kleinians: "a coherent split in the object, a coherent split in the ego, a fragmentation of the object, and a fragmentation of the ego."
