In his final book, renowned philosopher Pierre Hadot explores Goethe's relationship with ancient spiritual exercises--transformative acts of intellect, imagination, or will. Goethe sought both an intense experience of the present moment as well as a kind of cosmic consciousness, both of which are rooted in ancient philosophical practices. These practices shaped Goethe's audacious contrast to the traditional maxim memento mori (Don't forget that you will die) with the aim of transforming our ordinary consciousness. Ultimately, Hadot reveals how Goethe cultivated a deep love for life that brings to the forefront a new maxim: Don't forget to live.
