First published in 1979 but never available in English until now, Ego Sum challenges, through a careful and unprecedented reading of Descartess writings, the picture of Descartes as the father of modern philosophy: the thinker who founded the edifice of knowledge on the absolute self-certainty of a Subject fully transparent to itself. While other theoretical discourses, such as psychoanalysis, have also attempted to subvert this Subject, Nancy shows how they always inadvertently reconstituted the Subject they were trying to leave behind.
Nancys wager is that, at the moment of modern subjectivitys founding, a foundation that always already included all the possibilities of its own exhaustion, another thought of the subject is possible. By paying attention to the mode of presentation of Descartess subject, to the masks, portraits, feints, and fables that
populate his writings, Jean-Luc Nancy shows how Descartess ego is not the Subject of metaphysics but a mouth that spaces itself out and distinguishes itself.
Ego Sumis the most risky, and therefore most philosophically interesting, book concerning Descartes in the last forty years. Like Descartess own philosophy, it remains contemporary.Ego Sum proposes a provocative and unprecedented reading of Descartes. By paying attention to mode of presentation of Descartess philosophy, Nancy challenges our common understanding of the Cogito and shows how Descartess ego is not the self-certain, self-transparent Subject of metaphysics but a mouth that opens to utter: ego sum.
