On the basis of looking back the development of Husserl's research for intersubjectivity, this artical discusses mainly the constitution of other's experience (Fremderfahrung) in the sphere of ownness (die Eigenheitssphäre), and the relationship between the empathy of non-ownness (die uneigentliche Einfühlung) and the empathy of ownness (die eigentliche Einfühlung). The author holds that Husserl's intentional analysis of the role of the body in perception is his answer to such a problem: on what basis do I identify others as conscious beings like myself? At the same time the difference between the empathy of non-ownness and the empathy of ownness is not absolute. To awake to my own Ich is the transition from the empathy of non-ownness to the empathy of ownness. Although the critical readers have long been dissatisfied with the account of intersubjectivity put by Husserl in the field of transcendental philosophy, his account is significant for our analysis of intersubjectivity today.
