A long and turbulent affair between Jacques Derrida and Anglophone philosophy began when in 1967, Derrida presented "La Différance' in Oxford.¹ Besides Derrida's various brief mentions of the particular event, little else has been written about it. Derrida recounts it first in The Post Card, a series of quasi-fictional and quasi-autobiographical post-cards addressed to a lover, written, according to Derrida, on the back of a medieval picture of Plato and Socrates.
