Abstract
In contrast to the common notion of experiments as a means for testing theories, Science Studies currently emphasize the explorative character of experiments, thus elevating their systematic epistemological relevance. Consequently the experiment has become another challenge to Reichenbach′s distinction between discovery and justification, which has been valid in the philosophy of science for several decades. Repeatedly the experiment has served as an epistemological paradigm in philosophy. Engaging with recent positions in Science Studies the paper investigates Kant′s understanding of the use, meaning, and function of the experiment, focusing on its specifications with the catch words touchstone and the art of attempt. The historical and systematic approach shows to what extent the experiment is situated between freedom and coercion
