Abstract
This article aims to analyze the mechanisms of empirical data collection in medicine and psychology in the early Enlightenment by means of experiment, observation and self-observation, while associating them with their discursive forms of representation; namely, the case narrative. The combination of empirical and discursive anthropo-techniques leads to explanations on the anthropoietics of the Enlightenment; i.e., the question of how the habitus of man was shaped around 1750. Texts of four German ‘reasonable physicians’ will be considered: Friedrich Hoffmann, Johann Gottlieb Krüger, Andreas Elias Büchner and Johann August Unzer.
