publisher Niemeyer published the last chapter of the Logical Investigations again in 1922. Husserl notes in the preface:· "As things stand, I had to give in to the wishes of the friends of this work and decide to make its last chapter available again in its old form." With the phrase "the friend~ of this work," Husserl also wanted to say that he himself could not quite get close to the Logical Investigations after the publication of the Ideas. At the new place of his academic activity, the passion and effort of his thought turned toward the systematic development of the plan presented in the Ideas more than ever. Thus Husserl could write in the preface mentioned to the sixth investigation: "My teaching activity in Freiburg, too, furthered the direction of my interest toward general problems and the system."

Thus Husserl watched me in a generous fashion, but at the bottom in disagreement, as I worked on the Logical Investigations every week in special seminars with advanced students in addition to my lectures and regular seminars. Especially the preparation for this work was fruitful for me. There I learned one thing-at first rather led by surmise than guided by founded insight: What occurs for the phenomenology of the acts of consciousness as the self-manifestation of phenomena is thought more originally by Aristotle and in all Greek thinking and existence as ἀλήθεια, as the unconcealedness of what-is present, its being revealed, its showing itself. That which phenomenological investigations rediscovered as the supporting attitude of thought proves to be the fundamental trait of Greek thinking, if not indeed of philosophy as such.

The more decisively this insight became dear to me, the more pressing the question became: Whence and how is it determined what must be experienced as "the things themselves" in accordance with the principle of phenomenology? Is it consciousness and its objectivity or is it the Being of beings in its unconcealedness and concealment?

Thus I was brought to the path of the question of Being, illumined by the phenomenological attitude, again made uneasy in a different way than previously by the questions prompted by Brentano's dissertation. But the path of questioning became longer than I suspected.
