This essay proposes a reading of Joyce as intervening in the system of spatial mastery which we may designate in a general way as the “post”: the deployment and regulation of language as conditioned by its media of transmission and its function as that which is sent, dispatched, or delivered through space. We owe this notion of language implies a dispositif or putting-into-place that organizes human communication according to the identification of subjects with names and addresses that fix their locations, thereby designating them as senders and receivers between the relay-points of the message-systems that constitute the post. Joyce's characters are constantly solicited by the post in this sense; they are both subjected to and constituted as subjects by letters, post cards and other transmitted and circulated texts. Like other technologies, the post functions as an extension of the human that increases the power of the subject while diminishing its value. As a writer, Joyce is concerned with the consequences of this predicament for his own language, and for language in general.
