Contributions to Phenomenology

conditions of the possibility of Experience ... must mean nothing else than all that which lies immanently in the essence of Experience ... and therefore belongs to it indispensably. The essence of Experience that phenomenological analysis of Experience elucidates is the same as the possibility of Experience, and all that which is determined in the essence, in the possibility of Experience, is eo ipso 1 condition of the possibility of Experience. Through acquaintance with Husserl's work, then, I developed my way of understand­ ing what, according to their very possibility, lies in conscious activities of mentally representing something, for example, by imagining or remembering it, or by viewing it in a picture, all these understood as forms of modified perception. As Husserl himself made clear, such reflective and descriptive analyses of the mental activities according to their very possibility are carried out regardless of the way they have actually come to be. However, I was also interested in developmen­ tal questions, especially with regard to the activity of imagining. Hence I turned to cognitive developmental psychology in order to get acquainted with the neces­ sary empirical material. Moreover, I conducted a pilot-study with young children that I had conceived according to phenomenologically relevant aspects concerning the difference and yet inner connection of the activities of imagining and viewing 2 pictures.
