In this paper, I consider Thomas Soderquist's recent call for a biographica
l approach to historical narrative. He stresses in particular the need to p
ay greater attention to the existential struggles of our historical actors.
Echoing Raphael Samuel, he argues that this will help us to move away from
the hermeneutic of suspicion, which underlies the dominant sociological ap
proach, toward a hermeneutic of edification. Ultimately, this approach will
reestablish the moral purpose of historiography which has been lost in the
search for objectivity. While agreeing with the ultimate goal, I argue tha
t Soderquist's fundamentally conservative approach cannot produce edificati
on. Following Friedrich Nietzsche, Paul De Man and Jacques Derrida, I call
instead for a more reflexive approach which is conscious of the performativ
e character of historiography. I outline this alternative by seeking to rec
onstruct the life of Percy Lockhart-Mummery, a renown British surgeon who w
rote widely on cancer, natural history and the future of humanity. I focus
in particular on the struggle to find a unifying theme which might resolve
some tensions in Mummery's texts, tensions about the modern search for cert
ain knowledge, asking where exactly lies the difficulty, with the historica
l actor or the historian, While the emphasis placed on performance must inv
olve the dissolution of the reflecting self, I conclude that historical nar
rative can only edify if it speaks about the search for knowledge of its el
usive, evanescent author.
