Speaking about the influence Husserl had on his early thinking
Heidegger later on always referred to Husserl’s ‘Logische
Untersuchungen’ (1900/01), emphasizing the attitude of critical
distance he had towards the “Ideen zu einer reinen Phänomenologie
und phänomenologischen Philosophie” (1913) and
Husserl’s transcendental phenomenology pointed out there.
Nevertheless, as shown in this paper, it is evident that in ‘Being an
Time’ Heidegger took over some essential issues from Husserl’s
later work (as e.g. the transcendental attitude, the claim of
phenomenology to be a “productive logic” and the conception of
“regional ontologies”). But it is also clear that he was also
essentially changing their character.
