Radically divergent personalities can coexist in one person without canceling out

Evidence

For Roth, the writer, Demjanjuk’s ordinary homelife was no kind of alibi. The frightening thing was precisely that a person can be both that and this—the monstrous killing machine and the caring family man. The doubles coexist; they do not cancel each other out. “The Germans have proved definitively to all the world,” Real Roth observes, “that to maintain two radically divergent personalities, one very nice and one not so nice, is no longer the prerogative of psychopaths only.” — Naomi Klein, Doppelganger, 703

Categorization

• XREF: Directly connects to the reader’s overarching project: the ‘both that and this’ doubling is exactly the structure of Klein’s own conflation with Naomi Wolf and the diagonalist convergence being tracked throughout the book. — connects to: Human personality is measured on continuous spectrums, not sorted into fixed types — Sander van der Linden, Foolproof: Why Misinformation Infects…, 492
• DEEPTHINKING: The ‘doubles coexist; they do not cancel each other out’ formulation is the load-bearing metaphysical claim undergirding Klein’s entire Mirror World concept — the refusal to resolve Jekyll/Hyde into one or the other.
