This workshop (No. 2) is organized as part of a research project that focuses on the philosophical and institutional foundations of ‘scientific empiricism’, i.e., the association of rationality with systematic models which are compatible with experience and/or experiments . The project draw s a historical and conceptual line of reflection from the schools of the 14th century, through renaissance humanism, the early modern scientific revolution, the Kantian critique, up to and including contemporary science, while addressing the phenomenological attempt to found the natural and human sciences in the twentieth century.
