…[David Reimer] is cautioning us against the absolutism of distinction itself, for his phallus does not constitute the entirety of his worth. There is an incommensurability between who he is and what he has, an incommensurability between the phallus he has and what it is expected to be (and in this way no different from anyone with a phallus), which means that he has not become one with the norm, and yet he is still someone, speaking, insisting, even referring to himself. And it is from this gap, this incommensurability, between the norm that is supposed to inaugurate his humanness and the spoken insistence on himself that he performs that he derives his worth, that he speaks his worth. And we cannot precisely give content to this person at the very moment that he speaks his worth, which means that it is precisely the ways in which he is not fully recognizable, fully disposable, fully categorizable, that his humanness emerges. And this is important because we might ask that he enter into intelligibility in order to speak and to be known, but what he does instead, through his speech, is to offer a critical perspective on the norms the confer intelligibility itself. He shows, we might say, that there is an understanding to be had that exceeds the norms of intelligibility itself.
