A revised translation of Heidegger's most important work.

the Logische Untersuchungen,l phenomenology has been conceived as a substratum of empirical psychology, as a sphere comprising "imma nental" descriptions of psychical mental processes, a sphere compris ing descriptions that - so the immanence in question is understood - are strictly confined within the bounds of internal experience. It 2 would seem that my protest against this conception has been oflittle avail; and the added explanations, which sharply pinpointed at least some chief points of difference, either have not been understood (...) or have been heedlessly pushed aside. Thus the replies directed against my criticism of psychological method are also quite negative because they miss the straightforward sense of my presentation. My criticism of psychological method did not at all deny the value of modern psychology, did not at all disparage the experimental work done by eminent men. Rather it laid bare certain, in the literal sense, radical defects of method upon the removal of which, in my opinion, must depend an elevation of psychology to a higher scientific level and an extraordinary amplification ofits field of work. Later an occasion will be found to say a few words about the unnecessary defences of psychology against my supposed "attacks. (shrink)

THE TEXT In the summer semester of 1925 in Freiburg, Edmund Husserl delivered a lecture course on phenomenological psychology, in 1926127 a course on the possibility of an intentional psychology, and in 1928 a course entitled "Intentional Psychology. " In preparing the critical edition of Phiinomeno logische Psychologie (Husserliana IX), I Walter Biemel presented the entire 1925 course as the main text and included as supplements significant excerpts from the two subsequent courses along with pertinent selections from various research manuscripts (...) of Husserl. He also included as larger supplementary texts the final version and two of the three earlier drafts of Husserl's Encyclopedia Britannica article, "Phenomenology"2 (with critical comments and a proposed formulation of the Introduction and Part I of the second draft by Martin Heidegger3), and the text of Husserl's Amsterdam lecture, "Phenomenological Psychology," which was a further revision of the Britannica article. Only the main text of the 1925 lecture course (Husserliana IX, 1-234) is translated here. In preparing the German text for publication, Walter Biemel took as his basis Husserl's original lecture notes (handwritten in shorthand and I Hague: Nijhoff, 1962, 1968.

EDMUND HUSSERL in his early writings on space distinguishes three kinds of problems surrounding the presentation of space: psychological, logical, and metaphysical. By the term "psychology" Husserl means a descriptive and genetic psychology which seeks to characterize the contents and structure of particular experiences and to investigate the genetic relations between different experiences. Included among the genetic questions concerning space is the problem of the origin of the science of space.
