The articles collected in the present volume were written during a period of more than 30 years, the ?rst having been published in 1929, the last in 1961. They are arranged here in a systematic, not a chronological, order, starting from a few articles mainly concerned with psychological m- ters and then passing on to phenomenology in the proper sense. Within the latter group, the sequence is from articles dealing with more g- eral questions of principle to those in which rather special questions are discussed. The articles are reprinted or translated unchanged except for phenomenology of Thematics and of the Pure Ego, in which a certain number of pages have been omitted because the author has long since come to consider them erroneous. Almost all of the articles are in the service of Husserlian phenomen- ogy, which they are intended to advance and to develop further rather than merely expound. When the author made his ?rst acquaintance with Husserl´s philosophy about 40 years ago, he was overwhelmed by the spirit of uncompromising integrity and radical philosophical respon- bility, by the total devotedness which made the man disappear behind his work. Soon the young beginner came to realize the fruitfulness both of what Husserl had actually accomplished and of what he had initiated, the promise of further fruitful work.
