In Heidegger's fundamental text Being and Time (1927), "Dasein" is introduced as a term for the type of being that humans possess.[15] Dasein has been translated as "being there". Heidegger believes that Dasein already has a "pre-ontological" and non-abstract understanding that shapes how it lives. This mode of being he terms "being-in-the-world". Commentators have noted that Dasein and "being-in-the-world" are unitary concepts in contrast with the "subject/object" view of rationalist philosophy since at least René Descartes. Heidegger uses an analysis of Dasein to approach the question of the meaning of being, which Heidegger scholar Michael Wheeler describes as "concerned with what makes beings intelligible as beings".[16]

Heidegger was a member and supporter of the Nazi Party.[17][18] There is controversy as to the relationship between his philosophy and his Nazism.[19][20]
