Moritz Geiger developed an original phenomenological account of the splitting of the Ego in two papers, written in 1911 and 1913. Husserl read the 1911 paper as he was working on preliminary manuscripts to Ideas I. The first part of Husserl’s comments focused precisely on the splitting of the Ego. In this paper I will answer three questions: What is the historical-philosophical context of Geiger’s and Husserl’s discussion on the splitting of the ego? What are the phenomenological features of the splitting of the ego? What is the relevance of Geiger’s account of the splitting of the ego, for the further development of Husserl’s phenomenology? Reading Geiger was, indeed, the first occasion in which Husserl started to develop his own phenomenological account of the splitting of the ego. This will prove itself to be crucial for his mature analyses on the phenomenological reduction, as Husserl will distinguish more clearly between reflection and splitting of the ego.
