This first comprehensive historical and critical commentary on the works of Friedrich Nietzsche originates from the Heidelberg Academy of Sciences. Although Nietzsche is one of the most influential thinkers of the modern age, until now, no general commentary on his works as a whole has been published that addresses the full spectrum of underlying philosophical, historical, and literary factors and contexts. This Commentary on the Works of Friedrich Nietzsche will be an invaluable foundation for future research on Nietzsche. The entire edition will be completed in 2023.
