Gregor Schiemann (Wuppertal) gives a talk at the MCMP Colloquium (28 May, 2014) titled "Persistence of the lifeworld? On the relation of lifeworld and science". Abstract: In contrast to the concept of science, the concept of the lifeworld describes an experience, which is characterised by familiar social relations, actions that are performed as a matter of course, and a lack of professionalism. Divergent relations between science and the life-world are possible, as I will demonstrate in the first part, by considering exemplary processes of scientification of the lifeworld and their opposing tendencies. I judge the contradicting evaluations as an expression of a cultural change, in which the existence of the lifeworld as a non-scientific experience is at stake. To evaluate the situation, I develop a concept of lifeworld in the second part, that reveals an attitude towards the world, and performances of actions, both of which are historically contingent; and whose abolition can, today, already be imagined. In the concluding third part the fact that we are, however, somewhat far removed from a conceivable end of the lifeworld is demonstrated.
