Abstract
This chapter presents an overview of the Neo‐Kantian movement in philosophy that spanned the late nineteenth and early twentieth centuries and that was concentrated geographically in Germany. Following a summary of the institutional and intellectual context surrounding Neo‐Kantianism, the chapter explores the core philosophical principles associated with the movement, attending in particular to the ways in which Neo‐ Kantian philosophers appropriate and depart from the core tenets of Kant's critical philosophy. After briefly surveying the context in which Neo‐Kantianism took shape, the chapter surveys the two major “schools” into which the movement crystallized around 1880: the Marburg School, comprised primarily of Hermann Cohen, Paul Natorp, and Ernst Cassirer, and the Baden, or Southwest School, comprised principally of Wilhelm Windelband, Heinrich Rickert, and Emil Lask. Both schools of Neo‐ Kantianism are marked by a rich and fascinating process of internal conceptual development.
