Lebenswelt

Lifeworld (German: Lebenswelt) is a concept used in philosophy and in some social sciences, particularly sociology. It means the world "as lived" (German: erlebt) prior to reflective re-presentation or theoretical analysis. Edmund Husserl introduced the concept of the lifeworld in his Crisis of European Sciences (1936). Influences on Husserl's formulation of the lifeworld include Wilhelm Dilthey's "life-nexus" (German: Lebenszusammenhang) and Martin Heidegger's Being-in-the-world (German: In-der-Welt-Sein). The concept was further developed by students of Husserl such as Maurice Merleau-Ponty, Jan Patočka, and Alfred Schütz.
