By means of a survey of the papers given at the XIX Symposium of theSociety for History of Sciences on the „Idea of Purposiveness in the History of the Sciences“, Mai 28–30, 1981 in Bamberg, West Germany, it is demonstrated that in the course of the history of science teleological thinking in its traditional form is increasingly eliminated from the sciences. This process culminates in the attempt to rehabilitate teleological thinking by means of a reconstruction of Aristotelian philosophy using the (...) tools of modern natural science. The question arises whether this signifies the end of teleological thinking or a new direction of genuinely teleological thought. (shrink)
