With regard to its problems, the present work is concerned with Husserl's Ideen zu einer reinen Phänomenologie und phänomenologischen Philosophie, Volume I.² According to the Ideen, phenomenology is an eidetic science of consciousness and its most general structures. This fundamental conception serves as the basis on which the present analyses are developed and defines the historical standpoint of this essay. It will be phenomenology in the sense established by the Ideen.
