1. The book is a dialogue or a dialectic. At least it should be. . . . from the instant this logos can have been formed, when the possibility of dialogue has come into being, it might happen, thorugh an accident of circumstance, that I wouldn't have a partner handy: alone, then, I address this discourse to myself, I converse with myself in a sort of inward commerce. What I then hold is still a discourse but it is soundless, aphonic, private -- which also means deprived: of its mouthpiece, its voice.
Jacques Derrida, Disseminations, 184
