I think that taking life seriously means something such as this: that whatever man does on this planet has to be done in the lived truth of the terror of creation, of the grotesque, of the rumble of panic underneath everything. Otherwise it is false. Whatever is achieved must be achieved with the full exercise of passion, of vision, of pain, of fear, and of sorrow. How do we know.. That our part of the meaning of the universe might not be a rhythm in sorrow?
[W]e now know that the human animal is characterized by two great fears that other animals are protected from: the fear of life and the fear of death.. Heidegger brought these fears to the center of his existential philosophy. He argued that the basic anxiety of [humanity] is anxiety about being-in-the-world, as well as anxiety of being-in-the-world. That is, both fear of death and fear of life, of experience and individuation.
