雖然海德格話自己喺《存在同埋時間》係用現象學嘅方法， 不過佢同胡塞爾現象學嘅關係就好複雜。The fact that Heidegger believes that ontology includes an irreducible hermeneutic (interpretative) aspect, for example, might be thought to run counter to Husserl's claim that phenomenological description is capable of a form of scientific positivity. On the other hand, however, several aspects of the approach and method of Being and Time can be seen more directly in relation to Husserl's work.
