Abstract

This paper is concerned with the background to Lacan’s Seminar I, chapter xx on Augustine’s De magistro, its manuscript sources, editions and structure. The discussion of Augustine’s treatise was suggested to Lacan by Louis Beirnaert but he seems not to have known the text. We argue that there are reasons to think the suggestion came from his Jesuit confrere Paul Henry, the learned co-editor of the Enneads, who was helping to organise an international congress in Paris that year on Augustine. Although the history of the discussion of ‘signs’ goes back to Aristotle, the only attempt to bring signification into a theory of language, prior to Augustine, is found in a passage in Plotinus which Henry had discussed some years earlier. The Latin text of De magistro they used was, unfortunately, badly corrupted and this contributed to a mistaken understanding of its structure. Nevertheless, Lacan found some important parallels between Augustine’s view on teaching and the complexity of understanding and his own teaching and psychoanalysis.
