This work investigates the foundational role of the first-person perspective in shaping human cognition and moral agency. Béatrice Longuenesse, a prominent philosopher known for her work on Kant and German idealism, utilizes a rigorous analytical framework to examine how the 'I' functions as a necessary condition for both objective knowledge and ethical responsibility. She argues that the capacity to refer to oneself as 'I' is not merely a linguistic convenience but a structural requirement for rational thought and moral accountability.
