300 years ago Immanuel Kant was born - and I want to dedicate an extensive series of lectures to his whole philosophy. I spent the past year studying the 29 volumes of Kant's collected works and reading at least a 100 pages of Kant every day, in order to now provide the probably most comprehensive and most thorough presentation on his philosophy which has been attempted so far, to show its inner systematic relations and, most of all, to identify Kant's contribution to the aufklärung of humanity.
