The constitution of antepredicative experience was the constant concern of Husserl from the time of the Logical Investigations to that of the Crisis. Two strata can be distinguished concerning this: the first, elaborated in a Transcendental Aesthetic, defines, in a broad sense, the "primordial' world given to the individual Ego, solus ipse; the second, described in a Transcendental Theory of the perception of the other (Einfühlung) refers to the significations of intersubjectivity that are anterior to universality, properly so called.¹ The Transcendental Aesthetic itself consists of two parts: on the one hand, the constitution of lived experiences as "immanent objects' in the immanent time of internal sense, which is the subject matter of the lectures of 1905, published by Heidegger, and of group C of the unpublished manuscripts; on the other hand, the constitution of the primordial external object has been developed in numerous texts that extend over the whole of Husserl's career and of which the most recent have been assembled in Group D. Group E contains the major unpublished manuscripts that have been devoted to the theory of Einfühlung.
