To promote writing over speech undercuts the authority of the center. Yet the center is still there. Those who make their reputations as participants in conferences have renounced none of their privileges by denying the authority of their own presence. To deny it is the true proof that one has it. But to denounce the phallogocentric authority of speech is to renounce anthropological understanding of the communication that speech, or writing for that matter, effects.
Language is fetishized, set up as an independent force.
Although language speaks through the speaker, he or she gets the honorarium. It is just this ostensive ecstasy that is suppressed by metaphysics in the name of the harmony-bringing Idea. Such phenomena can only be explained by an anthropological rather than metaphysical model of presence. The speaker's presence before the community permits the deferral of violence. The central locus from which he speaks is undecidably that of the victim and that of the divinity to whom the victim is sacrificed.
