In Blade Runner, Rachael silently starts to cry when Deckard proves to her that she is a replicant. The silent grief over the loss of her “humanity,” […] or, [in the simple case of any human being who reflects on human existence] – the eternal gnawing doubt over whether I am truly human or just an android – it is these states which make me human.
